Study Notes

CPR and Cardiac Arrest Interventions

Complete chest recoil is essential for effective CPR, maximizing blood return to the heart.
Immediate unsynchronized high-energy shock is indicated for a patient unresponsive after cardiac arrest.
To minimize air entering the stomach during bag-mask ventilation, ventilate until visible chest rise occurs.
After administering a third shock in refractory ventricular fibrillation (vfib), the next step is to resume high-quality chest compressions.

Drug Administration and Patient Management

Following a second shock for vfib, administer 1 mg epinephrine IV/IO when chest compressions are resumed and bag-mask ventilations are effective.
For a patient with palpitations but no severe symptoms, initiate vagal maneuvers as the first intervention.
In cases of unresponsiveness and uncertain pulse presence, start high-quality CPR immediately.

STEMI and Reperfusion Strategies

Patients with a STEMI benefit significantly from reperfusion therapy to reduce in-hospital and 30-day mortality rates after chest pain resolution with sublingual nitroglycerin.
The maximum allowable pause for chest compressions during CPR is 10 seconds to maintain effectiveness.

CPR Technique and Guidelines

The recommended compression rate for high-quality CPR is 100 to 120 compressions per minute.
Ventilating too quickly during bag-mask ventilation can lead to gastric inflation and air entering the stomach.
After providing an AED shock, always resume chest compressions immediately.

Ensuring CPR Effectiveness

Switch chest compressors approximately every 2 minutes to prevent fatigue and maintain effective compressions.
If a patient with palpitations becomes light-headed after adenosine administration, the next dose of 12 mg adenosine IV is appropriate.
Administer 1 mg epinephrine IV for a patient already receiving CPR after experiencing a collapse following a pulmonary embolism.

Rescue Breathing and Chest Compression Depth

For an unresponsive, non-breathing patient with a palpable carotid pulse, initiate rescue breathing.
The depth of chest compressions for adults should be at least 2 inches to ensure adequate blood circulation.

Management of Hypotensive Patient

Administer 0.5 mg atropine IV to a patient exhibiting pale and diaphoretic symptoms with significantly low blood pressure (80/60 mm Hg).
