ACLS Airway Management & Ventilation 3

Question 1

What is the BURP maneuver and when is it used during direct laryngoscopy?

Accepted Answer

Backward-Upward-Rightward Pressure on the larynx to improve glottic visualization

Answer

BURP (Backward, Upward, Rightward Pressure) applied externally to the larynx improves visualization of the glottis during direct laryngoscopy.

Question 2

During 2-person bag-mask ventilation, what is the role of the second rescuer?

Accepted Answer

Use both hands to maintain a proper mask seal while the first rescuer squeezes the bag

Answer

In 2-person BVM technique, one rescuer forms an E-C clamp seal with both hands while the other compresses the bag, significantly improving tidal volume delivery.

Question 3

What is the primary advantage of video laryngoscopy over direct laryngoscopy in ACLS?

Accepted Answer

It provides an improved indirect view of the glottis, particularly in difficult airways

Answer

Video laryngoscopy displays a magnified view of the glottis on a screen, improving first-pass success rates especially in anatomically difficult airways.

Question 4

When waveform capnography is unavailable, what is the next best method to confirm ETT placement?

Accepted Answer

Colorimetric CO2 detector

Answer

A colorimetric CO2 detector provides chemical confirmation of ETT placement by changing color in the presence of exhaled CO2, serving as the backup when capnography is absent.

Question 5

After ROSC, what is the recommended ventilation rate and PaCO2 target for post-cardiac arrest care?

Accepted Answer

10-12 breaths/min targeting normocapnia (PaCO2 35-45 mmHg)

Answer

Post-ROSC guidelines recommend 10-12 breaths/min targeting normocapnia to avoid hyperventilation-induced cerebral vasoconstriction and hypocapnia.
