3. Which patients develop affective/psychological disorders of well-being after cardiac arrest, and are they Neurologic prognostication incorporates multiple diagnostic tests which are synthesized into a comprehensive multimodal assessment at least 72 hours after return to normothermia and with sedation and analgesia limited as possible. 1. If termination of resuscitation (TOR) is being considered, BLS EMS providers should use the BLS termination of resuscitation rule where ALS is not available or may be significantly delayed. Notably, in a clinical study in adults with outof- hospital VF arrest (of whom 43% survived to hospital discharge), the mean duty cycle observed during resuscitation was 39%. Recovery in the form of rehabilitation, therapy and support from family and healthcare providers. Bradycardia can be a normal finding, especially for athletes or during sleep. CPR indicates cardiopulmonary resuscitation; IHCA, in-hospital cardiac arrest; and OHCA, out-of-hospital cardiac arrest. 3. When appropriate, flow diagrams or additional tables are included. The systems-of-care approach to cardiac arrest includes the community and healthcare response to cardiac arrest. Which response by the medical assistant demonstrates closed-loop communication? After calling 911, follow the dispatcher's instructions. Conversely, when VF/ VT is more protracted, depletion of the hearts energy reserves can compromise the efficacy of defibrillation unless replenished by a prescribed period of CPR before the rhythm analysis. 5. What is the correct rate of ventilation delivery for a child or infant in respiratory arrest or failure? Providers should perform high-quality CPR and continuous left uterine displacement (LUD). 1. What are the ideal dose and formulation of IV lipid emulsion therapy? For lay rescuers trained in CPR using chest compressions and ventilation (rescue breaths), it is reasonable to provide ventilation (rescue breaths) in addition to chest compressions for the adult in OHCA. More research in this area is clearly needed. It may be reasonable to actively prevent fever in comatose patients after TTM. Whether resumption of CPR immediately after shock might reinduce VF/VT is controversial.52-54 This potential concern has not been borne out by any evidence of worsened survival from such a strategy. 4. Which term refers to the ability to use readily available resources to find solutions to challenging or complex situations or issues that arise? A patent airway is essential to facilitate proper ventilation and oxygenation. Which action should you perform first? 1. Maintaining the arterial partial pressure of carbon dioxide (Paco2) within a normal physiological range (generally 3545 mm Hg) may be reasonable in patients who remain comatose after ROSC. Many of the tests considered are subject to error because of the effects of medications, organ dysfunction, and temperature. Historically, the best motor examination in the upper extremities has been used as a prognostic tool, with extensor or absent movement being correlated with poor outcome. The precordial thump may be considered at the onset of a rescuer-witnessed, monitored, unstable ventricular tachyarrhythmia when a defibrillator is not immediately ready for use and is performed without delaying CPR or shock delivery. This topic last received formal evidence review in 2010.22. While orienting a new medical assistant to the facility, you find a patient who is unresponsive in the exam room. You are preparing to deliver ventilations to an adult patient experiencing respiratory arrest. Delivery of chest compressions without assisted ventilation for prolonged periods could be less effective than conventional CPR (compressions plus ventilation) because arterial oxygen content decreases as CPR duration increases. Electric pacing is not recommended for routine use in established cardiac arrest. Interposed abdominal compression CPR may be considered during in-hospital resuscitation when sufficient personnel trained in its use are available. The topic of neuroprotective agents was last reviewed in detail in 2010. IO access has grown in popularity given the relative ease and speed with which it can be achieved, a higher successful placement rate compared with IV cannulation, and the relatively low procedural risk. A 2017 systematic review identified 1 observational human study and 10 animal studies comparing different ventilation rates after advanced airway placement. A systematic review of the literature identified 5 small prospective trials, 3 retrospective studies, and multiple case reports and case series with contradictory results. Thus, we recognize that each of these diverse aspects of care contributes to the ultimate functional survival of the cardiac arrest victim. What is a reason you would choose to perform chest thrusts instead of abdominal thrusts for an adult or child with an obstructed airway? Flumazenil, a specific benzodiazepine antagonist, restores consciousness, protective airway reflexes, and respiratory drive but can have significant side effects including seizures and arrhythmia.1 These risks are increased in patients with benzodiazepine dependence and with coingestion of cyclic antidepressant medications. She is 28 weeks pregnant and her fundus is above the umbilicus. and 4. What is the validity and reliability of ETCO. 2020;142(suppl 2):S366S468. These recommendations are supported by Cardiac Arrest in Pregnancy: a Scientific Statement From the AHA9 and a 2020 evidence update.30, This topic was reviewed in an ILCOR systematic review for 2020.1 PE is a potentially reversible cause of shock and cardiac arrest. Which term refers to clearly and rationally identifying the connection between information and actions? Epinephrine should be administered early by intramuscular injection (or autoinjector) to all patients with signs of a systemic allergic reaction, especially hypotension, airway swelling, or difficulty breathing. Intracardiac drug administration was discouraged in the 2000 AHA Guidelines for CPR and Emergency Cardiovascular Care given its highly specialized skill set, potential morbidity, and other available options for access.1,2 Endotracheal drug administration results in low blood concentrations and unpredictable pharmacological effect and has also largely fallen into disuse given other access options. 5. 4. Cocaine toxicity can cause adverse effects on the cardiovascular system, including dysrhythmia, hypertension, tachycardia and coronary artery vasospasm, and cardiac conduction delays. The college is equipped with emergency equipment for use in the event of a release. 3. If using a defibrillator capable of escalating energies, higher energy for second and subsequent shocks may be considered for presumed shock-refractory arrhythmias. 2, and 3. The provision of rescue breaths for apneic patients with a pulse is essential. Central venous access is primarily used in the hospital setting because it requires appropriate training to acquire and maintain the needed skill set. Early delivery is associated with better maternal and neonatal survival.15 In situations incompatible with maternal survival, early delivery of the fetus may also improve neonatal survival. This will aid in both resource utilization and optimizing a patients chance for survival. 1. If a spinal injury is suspected or cannot be ruled out, providers should open the airway by using a jaw thrust instead of head tiltchin lift. Introduction. You yell to the medical assistant, "Go get the AED!" Epinephrine has been hypothesized to have beneficial effects during cardiac arrest primarily because of its -adrenergic effects, leading to increased coronary and cerebral perfusion pressure during CPR. The benefit of any specific target range of glucose management is uncertain in adults with ROSC after cardiac arrest. In 2013, a trial of over 900 patients compared TTM at 33C to 36C for patients with OHCA and any initial rhythm, excluding unwitnessed asystole, and found that 33C was not superior to 36C. Conversely, polymorphic VT not associated with a long QT is most often due to acute myocardial ischemia.4,5 Other potential causes include catecholaminergic polymorphic VT, a genetic abnormality in which polymorphic VT is provoked by exercise or emotion in the absence of QT prolongation6 ; short QT syndrome, a form of polymorphic VT associated with an unusually short QT interval (corrected QT interval less than 330370 milliseconds)7,8 ; and bidirectional VT seen in digitalis toxicity in which the axis of alternate QRS complexes shifts by 180 degrees.9 Supportive data for the acute pharmacological treatment of polymorphic VT, with and without long corrected QT interval, is largely based on case reports and case series, because no RCTs exist. The Adult OHCA and IHCA Chains of Survival have been updated to better highlight the evolution of systems of care and the critical role of recovery and survivorship with the addition of a new link. Check for no breathing or only gasping; if none, begin CPR with compressions. A systematic review of the literature evaluated all case reports of cardiac arrest in pregnancy about the timing of PMCD, but the wide range of case heterogeneity and reporting bias does not allow for conclusions. Since initial efforts for maternal resuscitation may not be successful, preparation for PMCD should begin early in the resuscitation, since decreased time to PMCD is associated with better maternal and fetal outcomes. As more and more centers and EMS systems are using feedback devices and collecting data on CPR measures such as compression depth and chest compression fraction, these data will enable ongoing updates to these recommendations. 1. In adult victims of cardiac arrest, it is reasonable for rescuers to perform chest compressions at a rate of 100 to 120/min. Routine stabilization of the cervical spine in the absence of circumstances that suggest a spinal injury is not recommended. An IV dose of 0.05 to 0.1 mg (5% to 10% of the epinephrine dose used routinely in cardiac arrest) has been used successfully for anaphylactic shock. Data on the relative benefit of continuous versus intermittent EEG are limited. After identifying a cardiac arrest, a lone responder should activate the emergency response system first and immediately begin CPR. A recent meta-analysis of 13 RCTs (990 evaluable patients) found that adverse events and serious adverse events were more common in patients who were randomized to receive flumazenil than placebo (number needed to harm: 5.5 for all adverse events and 50 for serious adverse events). Which intervention should the nurse implement? Vasopressor medications during cardiac arrest. Several RCTs have compared a titrated approach to oxygen administration with an approach of administering 100% oxygen in the first 1 to 2 hours after ROSC. Success rates for the Valsalva maneuver in terminating SVT range from 19% to 54%. 4. Independent of a patients mental status, coronary angiography is reasonable in all postcardiac arrest patients for whom coronary angiography is otherwise indicated. There is no published evidence on the safety, effectiveness, or feasibility of mouth-to-stoma ventilation. Responders are normally the first on the scene of an emergency, and range from police, fire, and emergency health personnel, to . Two RCTs compared a strategy of targeting highnormal Paco2 (4446 mmHg) with one targeting low-normal Paco. The treatment of nonconvulsive seizures (diagnosed by EEG only) may be considered. Lay rescuers may provide chest compression only CPR to simplify the process and encourage CPR initiation, whereas healthcare providers may provide chest compressions and ventilation (Figures 24). In small case series, IV magnesium has been effective in suppressing and preventing recurrences of. The available evidence suggests no appreciable differences in success or major adverse event rates between calcium channel blockers and adenosine.2. To assure successful maternal resuscitation, all potential stakeholders need to be engaged in the planning and training for cardiac arrest in pregnancy, including the possible need for PMCD. A lone healthcare provider should commence with chest compressions rather than with ventilation. Injection of epinephrine into the lateral aspect of the thigh produces rapid peak plasma epinephrine concentrations. A dispatcher can speak to the person in need through a speaker phone B. Currently marketed defibrillators use proprietary shock waveforms that differ in their electric characteristics. This time delay is a consistent issue in OHCA trials. The BLS care of adolescents follows adult guidelines. The trained lay rescuer who feels confident in performing both compressions and ventilation should open the airway using a head tiltchin lift maneuver when no cervical spine injury is suspected. IO access is increasingly implemented as a first-line approach for emergent vascular access. Adenosine should not be administered for hemodynamically unstable, irregularly irregular, or polymorphic wide-complex tachycardias. During a resuscitation, the team leader assigns team roles and tasks to each member. 1. In the PRIMED study (n=8178), the use of the ITD (compared with a sham device) did not significantly improve survival to hospital discharge or survival with good neurological function in patients with OHCA. . The response phase is a reaction to the occurrence of a catastrophic disaster or emergency. Due to the potential effects of intrinsic positive end-expiratory pressure (auto-PEEP) and risk of barotrauma in an asthmatic patient with cardiac arrest, a ventilation strategy of low respiratory rate and tidal volume is reasonable. What is the effect of hypocarbia or hypercarbia on outcome after cardiac arrest? This begins with opening the airway followed by delivery of rescue breaths, ideally with the use of a bag-mask or barrier device. Important considerations for determining airway management strategies is provider airway management skill and experience, frequent retraining for providers, and ongoing quality improvement to minimize airway management complications. A 2015 systematic review reported significant heterogeneity among studies, with some studies, but not all, reporting better rates of survival to hospital discharge associated with higher chest compression fractions. and 2. The 2019 focused update on ACLS guidelines addressed the use of advanced airways in cardiac arrest and noted that either bag-mask ventilation or an advanced airway strategy may be considered during CPR for adult cardiac arrest in any setting.1 Outcomes from advanced airway and bag-mask ventilation interventions are highly dependent on the skill set and experience of the provider (Figure 7). Thus, the confidence in the prognostication of the diagnostic tests studied is also low. For cardiac arrest with known or suspected hypermagnesemia, in addition to standard ACLS care, it may be reasonable to administer empirical IV calcium. 3. This recommendation is based on the overall principle of minimizing interruptions to CPR and maintaining a chest compression fraction of at least 60%, which studies have reported to be associated with better outcome. Although an advanced airway can be placed without interrupting chest compressions. 3. If hemodynamically stable, a presumptive rhythm diagnosis should be attempted by obtaining a 12-lead ECG to evaluate the tachycardias features. 4. Severe exacerbations of asthma can lead to profound respiratory distress, retention of carbon dioxide, and air trapping, resulting in acute respiratory acidosis and high intrathoracic pressure. 1. MEMPHIS, Tenn. Two Memphis Fire Department emergency medical technicians who were fired and had their licenses suspended for failing to . The main focus in adult cardiac arrest events includes rapid recognition, prompt provision of CPR, defibrillation of malignant shockable rhythms, and post-ROSC supportive care and treatment of underlying causes. These recommendations are supported by the 2018 American College of Cardiology, AHA, and Heart Rhythm Society guideline on the evaluation and management of patients with bradycardia and cardiac conduction delay.16. External chest compressions should be performed if emergency resternotomy is not immediately available. Electrolyte abnormalities may cause or contribute to cardiac arrest, hinder resuscitative efforts, and affect hemodynamic recovery after cardiac arrest. ADC indicates apparent diffusion coefficient; CPR, cardiopulmonary resuscitation; CT, computed tomography; ECG, electrocardiogram; ECPR, extracorporeal In addition to defibrillation, several alternative electric and pseudoelectrical therapies have been explored as possible treatment options during cardiac arrest. In addition, 15 recommendations are designated Class 3: No Benefit, and 11 recommendations are Class 3: Harm. The literature supports prioritizing defibrillation and CPR initially and giving epinephrine if initial attempts with CPR and defibrillation are not successful. In intubated patients, failure to achieve an end-tidal CO. 5. Many cardiac arrest patients who survive the initial event will eventually die because of withdrawal of life-sustaining treatment in the setting of neurological injury. In determining the COR, the writing group considered the LOE and other factors, including systems issues, economic factors, and ethical factors such as equity, acceptability, and feasibility. Few patients who develop cardiac arrest from carbon monoxide poisoning survive to hospital discharge, regardless of the treatment administered after ROSC, though rare good outcomes have been described. Recommendation 1 is supported by the 2019 focused update on ACLS guidelines.3 Recommendation 2 last received formal evidence review in 2015.4 Recommendation 3 is supported by the 2020 CoSTR for ALS.11, These recommendations are supported by the 2015 Guidelines Update24 and a 2020 evidence update.11. Do antiarrhythmic drugs, when given in combination for cardiac arrest, improve outcomes from cardiac Can point-of-care cardiac ultrasound, in conjunction with other factors, inform termination of These recommendations are supported by the 2020 CoSTR for ALS,4 which supplements the last comprehensive review of this topic conducted in 2015.7. When Mr. Phillips shows signs of ROSC, where should you perform the pulse check? You are working in an OB/GYN office when your patient, Mrs. Tribble, suddenly goes into cardiac arrest. Individual test modalities may be obtained earlier and the results integrated into the multimodality assessment synthesized at least 72 hours after normothermia. 7. What is the optimal approach, vasopressor or transcutaneous pacing, in managing symptomatic Vasopressin alone or vasopressin in combination with epinephrine may be considered in cardiac arrest but offers no advantage as a substitute for epinephrine in cardiac arrest. No shock waveform has distinguished itself as achieving a consistently higher rate of ROSC or survival. The team is delivering 1 ventilation every 6 seconds. Before placement of an advanced airway (supraglottic airway or tracheal tube), it is reasonable for healthcare providers to perform CPR with cycles of 30 compressions and 2 breaths. 3. The same anticonvulsant regimens used for the treatment of seizures caused by other etiologies may be considered for seizures detected after cardiac arrest. Regardless of waveform, successful defibrillation requires that a shock be of sufficient energy to terminate VF/VT. Rescuers should recognize that multiple approaches may be required to establish an adequate airway. Precharging the defibrillator during ongoing chest compressions shortens the hands-off chest time surrounding defibrillation, without evidence of harm. If recurrent opioid toxicity develops, repeated small doses or an infusion of naloxone can be beneficial. It is preferred to perform CPR on a firm surface and with the victim in the supine position, when feasible. 1. IHCA patients often have invasive monitoring devices in place such as central venous or arterial lines, and personnel to perform advanced procedures such as arterial blood gas analysis or point-of-care ultrasound are often present. Notably, when the QRS complex is of uniform morphology, shock synchronized to the QRS is encouraged because this minimizes the risk of provoking VF by a mistimed shock during the vulnerable period of the cardiac cycle (T wave). 4. The BLS TOR rule recommends TOR when all of the following criteria apply before moving to the ambulance for transport: (1) arrest was not witnessed by EMS providers or first responder; (2) no ROSC obtained; and (3) no shocks were delivered. Interposed abdominal compression CPR is a 3-rescuer technique that includes conventional chest compressions combined with alternating abdominal compressions. Observational studies of fibrinolytic therapy for suspected PE were found to have substantial bias and showed mixed results in terms of improvement in outcomes. How does this affect compressions and ventilations? All lay rescuers should, at minimum, provide chest compressions for victims of cardiac arrest. 4. Immediate defibrillation is the treatment of choice when torsades is sustained or degenerates to VF. Possible contributors to this goal include optimization of cerebral perfusion pressure, management of oxygen and carbon dioxide levels, control of core body temperature, and detection and treatment of seizures (Figure 9). What should you do? neurological outcome? 1. Because any single method of neuroprognostication has an intrinsic error rate and may be subject to confounding, multiple modalities should be used to improve decision-making accuracy. Refer to the device manufacturers recommended energy for a particular waveform. The nurse assesses a responsive adult and determines she is choking. You have assessed your patient and recognized that they are in cardiac arrest. They should perform continuous LUD until the infant is delivered, even if ROSC is achieved. Because the duration of action of naloxone may be shorter than the respiratory depressive effect of the opioid, particularly long-acting formulations, repeat doses of naloxone, or a naloxone infusion may be required. How is a child defined in terms of CPR/AED care? We recommend that laypersons initiate CPR for presumed cardiac arrest, because the risk of harm to the patient is low if the patient is not in cardiac arrest. Excessive ventilation is unnecessary and can cause gastric inflation, regurgitation, and aspiration. and 2. The routine use of cricoid pressure in adult cardiac arrest is not recommended. 4. What is the interrater agreement for physical examination findings such as pupillary light reflex, corneal Airway management during cardiac arrest usually commences with a basic strategy such as bag-mask ventilation. insulin) for refractory shock due to -adrenergic blocker or calcium channel blocker overdose? Anaphylaxis causes the immune system to release a flood of chemicals that can cause you to go into shock blood pressure drops suddenly and the airways narrow, blocking breathing. 2. 5. Many alternatives and adjuncts to conventional CPR have been developed. Mouth-to-mouth ventilation in the water may be helpful when administered by a trained rescuer if it does not compromise safety. Look for no breathing or only gasping, at the direction of the telecommunicator. The ALS TOR rule recommends TOR when all of the following criteria apply before moving to the ambulance for transport: (1) arrest was not witnessed; (2) no bystander CPR was provided; (3) no ROSC after full ALS care in the field; and (4) no AED shocks were delivered. A victim may also appear clinically dead because of the effects of very low body temperature. Maintaining a patent airway and providing adequate ventilation and oxygenation are priorities during CPR.

While amiodarone is typically considered a rhythm-control agent, it can effectively reduce ventricular rate with potential use in patients with congestive heart failure where -adrenergic blockers may not be tolerated and nondihydropyridine calcium channel antagonists are contraindicated. 1. This topic was last reviewed in 2010 and identified 2 randomized trials, interposed abdominal compression CPR performed by trained rescuers improved short-term survival. In patients with atrial fibrillation and atrial flutter in the setting of preexcitation, digoxin, nondihydropyridine calcium channel antagonists, -adrenergic blockers, and IV amiodarone should not be administered because they may increase the ventricular response and result in VF. Clinical trials and observational studies since the 2010 Guidelines have yielded no new evidence that routine administration of sodium bicarbonate improves outcomes from undifferentiated cardiac arrest and evidence suggests that it may worsen survival and neurological recovery.
