ACLS ACLS Airway Management

Question 1

What is the preferred initial airway management technique during cardiac arrest before an advanced airway is placed?

Accepted Answer

Bag-mask ventilation

Answer

Bag-mask ventilation is the preferred initial method for providing ventilations during cardiac arrest until an advanced airway can be established.

Question 2

When performing bag-mask ventilation during CPR, what is the recommended tidal volume?

Accepted Answer

500–600 mL (enough to produce visible chest rise)

Answer

Tidal volumes of 500–600 mL, sufficient to produce visible chest rise, are recommended to avoid gastric inflation and barotrauma.

Question 3

After placement of an advanced airway during CPR, what is the recommended ventilation rate?

Accepted Answer

1 breath every 6 seconds (10 breaths/min)

Answer

Once an advanced airway is in place, deliver asynchronous ventilations at a rate of 10 breaths per minute (one breath every 6 seconds).

Question 4

Which waveform capnography value indicates adequate CPR quality and likely myocardial perfusion during resuscitation?

Accepted Answer

PETCO2 ≥ 20 mmHg

Answer

A PETCO2 of 20 mmHg or greater during CPR suggests adequate cardiac output and is associated with improved survival.

Question 5

What is the most reliable confirmation method to verify correct endotracheal tube placement?

Accepted Answer

Waveform capnography

Answer

Waveform capnography is the most reliable continuous method for confirming and monitoring correct ETT placement throughout resuscitation.
