Are you performing all of the required ITM on your Emergency Power Supply System? Distinguishing between these rhythm etiologies is the key to proper drug selection for treatment. 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. When an emergency or disaster does occur, fire and police units, emergency medical personnel, and rescue workers rush to damaged areas to provide aid. The use of an airway adjunct (eg, oropharyngeal and/or nasopharyngeal airway) may be reasonable in unconscious (unresponsive) patients with no cough or gag reflex to facilitate delivery of ventilation with a bag-mask device. after initiating CPR you and 2 nurses have been performing CPR on a 72 year old patient, Ben Phillips. The effect of individual CPR quality metrics or interventions is difficult to evaluate because so many happen concurrently and may interact with each other in their effect. Answer the dispatchers questions, and follow the telecommunicators instructions. Do steroids improve shock or other outcomes in patients who remain hypotensive after ROSC? Key topics in postresuscitation care that are not covered in this section, but are discussed later, are targeted temperature management (TTM) (Targeted Temperature Management), percutaneous coronary intervention (PCI) in cardiac arrest (PCI After Cardiac Arrest), neuroprognostication (Neuroprognostication), and recovery (Recovery). 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. 3. 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. The American Heart Association is a qualified 501(c)(3) tax-exempt organization. 3. The electric characteristics of the VF waveform are known to change over time. Two randomized, placebo-controlled trials, enrolling over 8500 patients, evaluated the efficacy of epinephrine for OHCA.1,2 A systematic review and meta-analysis of these and other studies3 concluded that epinephrine significantly increased ROSC and survival to hospital discharge. The routine use of steroids for patients with shock after ROSC is of uncertain value. No adult human studies directly compare levels of inspired oxygen concentration during CPR. Registration staff asked the remaining questions at the patient bedside during their ED stay, reducing unnecessary delays in registration and more . 1. EEG patterns that were evaluated in the 2020 ILCOR systematic review include unreactive EEG, epileptiform discharges, seizures, status epilepticus, burst suppression, and highly malignant EEG. Administration of amiodarone or lidocaine to patients with OHCA was last formally reviewed in 2018. When performed with other prognostic tests, it may be reasonable to consider bilaterally absent pupillary light reflex at 72 h or more after cardiac arrest to support the prognosis of poor neurological outcome in patients who remain comatose. Which statement is true regarding CPR and AED use for a pregnant patient? A 2015 systematic review found that prehospital cooling with the specific method of the rapid infusion of cold IV fluids was associated with more pulmonary edema and a higher risk of rearrest. 4. 6. 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. 1. Lifesaving procedures, including standard BLS and ACLS, are therefore important to continue until a patient is rewarmed unless the victim is obviously dead (eg, rigor mortis or nonsurvivable traumatic injury). Airway, ventilation, and oxygenation are particularly important in the setting of pregnancy because of increased maternal metabolism and decreased functional reserve capacity due to the gravid uterus, making pregnant patients more prone to hypoxia. Any contact who is symptomatic should immediately be considered a case and should be send home to self-isolate and . A 2020 ILCOR systematic review identified 3 studies involving 57 total patients that investigated the effect of hand positioning on resuscitation process and outcomes. This topic was last reviewed in 2010 and identified 2 randomized trials, interposed abdominal compression CPR performed by trained rescuers improved short-term survival. Which is the most appropriate action? 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. Because pregnant patients are more prone to hypoxia, oxygenation and airway management should be prioritized during resuscitation from cardiac arrest in pregnancy. The rationale for tracking the overall success rate for systems performing ETI is to make informed decisions as to whether practice should allow for ETI, move toward SGA, or simply use bag-mask ventilation for patients in cardiac arrest; recommendations will vary depending on the overall success rate in a given system. 3. If increased auto-PEEP or sudden decrease in blood pressure is noted in asthmatics receiving assisted ventilation in a periarrest state, a brief disconnection from the bag mask or ventilator with compression of the chest wall to relieve air-trapping can be effective. Much of the published research involves patients whose arrests were presumed to be of cardiac origin and in settings with short EMS response times. However, there are several case reports of good maternal and fetal outcome with the use of TTM after cardiac arrest. While providing ventilations, you notice that Mr. Sauer moves and appears to be breathing. 4. Because there are no studies demonstrating improvement in patient outcomes from administration of naloxone during cardiac arrest, provision of CPR should be the focus of initial care. Advanced monitoring such as ETCO2 monitoring is being increasingly used. When VF/VT has been present for more than a few minutes, myocardial reserves of oxygen and other energy substrates are rapidly depleted. There is concern that delivery of chest compressions without assisted ventilation for prolonged periods could be less effective than conventional CPR (compressions plus breaths) because the arterial oxygen content will decrease as CPR duration increases. Conversely, the -adrenergic effects may increase myocardial oxygen demand, reduce subendocardial perfusion, and may be proarrhythmic. After symptoms have been identified and a bystander has called 9-1-1 or an equivalent emergency response system, the next step in the chain of survival is to immediately begin cardiopulmonary resuscitation or CPR. Many alternatives and adjuncts to conventional CPR have been developed. We recommend that epinephrine be administered for patients in cardiac arrest. 2. A 7-year-old patient goes into sudden cardiac arrest. Recovery expectations and survivorship plans that address treatment, surveillance, and rehabilitation need to be provided to cardiac arrest survivors and their caregivers at hospital discharge to optimize transitions of care to home and to the outpatient setting. 2. However, good outcomes have been observed with rapid resternotomy protocols when performed by experienced providers in an appropriately equipped ICU. Components include venous cannula, a pump, an oxygenator, and an arterial cannula. However, an oral airway is preferred because of the risk of trauma with a nasopharyngeal airway. In these cases, this maneuver should be used even in cases of potential spinal injury because the need to open the airway outweighs the risk of further spinal damage in the cardiac arrest patient. When an arrest occurs in the hospital, a strong multidisciplinary approach includes teams of medical professionals who respond, provide CPR, promptly defibrillate, begin ALS measures, and continue post-ROSC care. 2. Which intervention should the nurse implement? You suspect that an unresponsive patient has sustained a neck injury. Immediately initiate chest compressions. 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. 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. How is a child defined in terms of CPR/AED care? When the college alarms are sounded the appropriate fire and emergency response personnel are immediately contacted. 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. Because of the limitation in exhalational air flow, delivery of large tidal volumes at a higher respiratory rate can lead to progressive worsening of air trapping and a decrease in effective ventilation. Which compression depth is appropriate for this patient? Injection of epinephrine into the lateral aspect of the thigh produces rapid peak plasma epinephrine concentrations. There is no proven benefit from the use of antihistamines, inhaled beta agonists, and IV corticosteroids during anaphylaxis-induced cardiac arrest. These recommendations are supported by the 2019 focused update on ACLS guidelines.1. Immediate defibrillation is reasonable for provider-witnessed or monitored VF/pVT of short duration when a defibrillator is already applied or immediately available. These recommendations are supported by the 2020 CoSTR for ALS,4 which supplements the last comprehensive review of this topic conducted in 2015.7. The majority of recommendations are based on Level C evidence, including those based on limited data (123 recommendations) and expert opinion (31 recommendations). 4. Care of any patient with cardiac arrest in the setting of acute exacerbation of asthma begins with standard BLS. Cycles of 5 back blows and 5 chest thrusts. 1. Fever after ROSC is associated with poor neurological outcome in patients not treated with TTM, although this finding is reported less consistently in patients treated with TTM. SEMS Emergency Response Criteria. arrest with shockable rhythm? You are providing compressions on a 6-month-old who weighs 17 pounds. the functional capacity and safety of hospitals and the health-care system at large. Immediate defibrillation by a trained provider presents distinct advantages in these patients, whereas the morbidity associated with external chest compressions or resternotomy may substantially impact recovery. IV bolus administration of potassium for cardiac arrest in suspected hypokalemia is not recommended. neurological outcome? Critical knowledge gaps are summarized in Table 4. When 2 or more rescuers are available, it is reasonable to switch chest compressors approximately every 2 min (or after about 5 cycles of compressions and ventilation at a ratio of 30:2) to prevent decreases in the quality of compressions. 3. If so, what dose and schedule should be used? 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. In unmonitored cardiac arrest, it is reasonable to provide a brief prescribed period of CPR while a defibrillator is being obtained and readied for use before initial rhythm analysis and possible defibrillation. Despite steady improvement in the rate of survival from IHCA, much opportunity remains. Toxicity: carbon monoxide, digoxin, and cyanide. These recommendations are supported by the 2020 Respiratory rate over 28/min or less than 8/min. In addition, deterioration of fetal status may be an early warning sign of maternal decompensation. An analysis of data from the AHAs Get With The Guidelines-Resuscitation registry showed higher likelihood of ROSC (odds ratio, 1.22; 95% CI, 1.041.34; Studies have reported that enough tidal volume to cause visible chest rise, or approximately 500 to 600 mL, provides adequate ventilation while minimizing the risk of overdistension or gastric insufflation. The team should provide ventilations at a rate of 1 ventilation every 6 seconds without pausing compressions. A two-person technique is the preferred methodology for bag-valve-mask (BVM) ventilations as it provides better seal and ventilation volume. Since this topic was last updated in detail in 2015, at least 2 randomized trials have been completed on the effect of steroids on shock and other outcomes after ROSC, only 1 of which has been published to date. Do prophylactic antiarrhythmic medications on ROSC after successful defibrillation decrease arrhythmia Many of the tests considered are subject to error because of the effects of medications, organ dysfunction, and temperature. What is the validity and reliability of ETCO. In nonintubated patients, a specific end-tidal CO. 1. How does this affect compressions and ventilations? If an adult victim with spontaneous circulation (ie, strong and easily palpable pulses) requires support of ventilation, it may be reasonable for the healthcare provider to give rescue breaths at a rate of about 1 breath every 6 s, or about 10 breaths per minute. outcomes? Although a few EMS systems have demonstrated the ability to significantly increase survival rates (Nichol et al . 3. She is 28 weeks pregnant and her fundus is above the umbilicus. In small case series, IV magnesium has been effective in suppressing and preventing recurrences of. In cases of prehospital maternal arrest, rapid transport directly to a facility capable of PMCD and neonatal resuscitation, with early activation of the receiving facilitys adult resuscitation, obstetric, and neonatal resuscitation teams, provides the best chance for a successful outcome. At least 1 retrospective study on ECMO use for patients with cardiac arrest or refractory shock in the setting of drug toxicity has reported improved outcomes.
