Study Notes
Cardiac Arrest and Resuscitation
- Early CPR is crucial for enhancing survival rates from cardiac arrest.
- Local protocols govern the issuance of valid "cease resuscitation" orders by authorities.
- Automatic External Defibrillators (AEDs) may struggle to analyze rhythms in moving vehicles.
CPR and Defibrillation
- After delivering a shock with an AED, resume chest compressions immediately to maintain circulation.
- If no shock is indicated, administer 5 cycles of CPR before re-evaluating the patient's condition.
- Ventricular Tachycardia is a critical dysrhythmia that necessitates the swift application of an AED.
Advanced Life Support (ALS)
- ALS providers can receive termination orders if patients show no response to Basic Life Support (BLS) and ALS interventions.
- Early defibrillation is not categorized as part of post-arrest care.
AED Usage
- An AED should not be used if the patient is in contact with metal due to the risk of improper shock delivery.
- Biphasic AEDs deliver shocks in both directions, enhancing effectiveness.
Mechanical and Device Considerations
- The Lucas CPR device requires briefly stopping CPR to position a base plate under the patient.
- Patients with ventricular assist devices may not have a detectable pulse or blood pressure, despite the device functioning properly.
- Aortic Valve Stenosis is identified as a mechanical failure of the heart that can result in cardiac arrest.
