Study Notes

Chest Compressions and Ventilation

Chest compressions for adults should be delivered at a rate of 100-120 compressions per minute.
The recommended compression-to-breath ratio in adults during CPR is 30:2.
For adults in respiratory arrest, bag valve mask ventilation should occur once every 5-6 seconds (10-12 times per minute).

Treatments and Procedures

Hypotension following cardiac arrest can be treated with IV dopamine and epinephrine infusions, along with IV Ringer's lactate or IV normal saline.
The leader in team resuscitation must be proficient in all necessary skills.
The ED door-to-balloon inflation time for STEMI patients should not exceed 90 minutes.

CPR Effectiveness and Drugs

Effectiveness of CPR can be estimated through arterial diastolic blood pressure, quantitative waveform capnography, and central venous oxygen saturation.
Adenosine is the drug of choice for treating narrow complex supraventricular tachycardia, with an initial dose of 6 mg IV.
Epinephrine is used for pulseless electrical activity.

BLS and ACS Guidelines

The sequence for basic life support (BLS) is Compressions, Airway, Breathing (CAB).
The recommended oxygen dosage during CPR is 100%.
Atropine should be administered at an initial dosage of 0.5 mg IV for symptomatic bradycardia.

Cardiac Events and Interventions

The heart rate at which tachycardia typically becomes symptomatic is around 150 bpm.
The maximum duration for pulse checks should not exceed 10 seconds.
Fibrinolytic therapy for stroke patients should ideally begin within 1 hour of ED arrival.

Key Syndrome and Causes

Cardiac arrest can be triggered by common reversible causes known as the "H's and T's," which include hypotension, hypoxia, hypothermia, and various forms of thrombosis.
The best procedure for treating STEMI diagnosed in an ambulance is to transport the patient to a PCI-capable hospital.

Stroke Assessment and AED Use

The Cincinnati Prehospital Stroke Scale (CPSS) assesses facial droop, arm drift, and speech abnormalities.
When an AED encounters issues analyzing rhythm, chest compressions should continue uninterrupted.

Synchronized Shocks and Medications

Unstable atrial fibrillation is treated with synchronized shocks, while sinus tachycardia, VT without a pulse, and VF are not.
Procainamide should be administered at a dose of 20-50 mg/min.
All acute coronary syndrome (ACS) patients should receive aspirin.

Other Important Considerations

The concentration for a maintenance amiodarone drip is 900 mg in 500 mL D5W (1.8 mg/mL).
EMS dispatchers observing ACS symptoms should advise patients to take aspirin.
The longest acceptable delay in administering chest compressions is 10 seconds.

Advanced Cardiac Care

Persistent hypotension in patients paced at 75/min may suggest an underlying condition other than pacing.
A successful resuscitation effort requires a systematic approach known as a system of care.
Magnesium sulfate may assist cardiac arrest patients with hypokalemia.

Ventilation and Monitoring

The ideal tidal volume for bag valve mask ventilation is 600 mL.
The goal for percutaneous coronary intervention (PCI) after hospital arrival is to achieve it within 90 minutes.
The most common cause of upper airway obstruction in unconscious patients is the loss of muscle tone in the throat.

BLS and ACLS Surveys

The ABCD of the BLS primary survey includes Airway, Breathing, Circulation, and Defibrillation.
The ABCD of the ACLS secondary survey encompasses Airway, Breathing, Circulation, and Differential Diagnosis.
Hyperventilation carries risks of increased intrathoracic pressure, which can decrease venous return and cardiac output.
