ACLS ACLS Airway Management and Ventilation

Question 1

What is the preferred initial airway adjunct for an unconscious adult patient who lacks a gag reflex during ACLS?

Accepted Answer

Oropharyngeal airway (OPA)

Answer

An oropharyngeal airway (OPA) is the preferred initial airway adjunct for unconscious patients without a gag reflex to maintain airway patency.

Question 2

During bag-mask ventilation in ACLS, what tidal volume is recommended to avoid gastric inflation?

Accepted Answer

500–600 mL (visible chest rise)

Answer

Tidal volumes of 500–600 mL (enough to produce visible chest rise) are recommended to minimize gastric inflation and barotrauma.

Question 3

Which device provides the MOST reliable protection against aspiration during advanced airway management in ACLS?

Accepted Answer

Endotracheal tube (ETT)

Answer

The endotracheal tube, when properly placed and cuffed, provides the most reliable protection against aspiration by isolating the trachea.

Question 4

After intubation, which is the MOST reliable method to confirm endotracheal tube placement?

Accepted Answer

Waveform capnography

Answer

Waveform capnography is the most reliable method for confirming and continuously monitoring correct ETT placement during ACLS.

Question 5

During cardiac arrest with an advanced airway in place, what is the recommended ventilation rate?

Accepted Answer

1 breath every 6 seconds (10 breaths/min)

Answer

Once an advanced airway is secured during cardiac arrest, deliver 1 breath every 6 seconds (10 breaths/min) without pausing chest compressions.
