What is the BURP maneuver and when is it used during direct laryngoscopy?
Answer: Backward-Upward-Rightward Pressure on the larynx to improve glottic visualization
BURP (Backward, Upward, Rightward Pressure) applied externally to the larynx improves visualization of the glottis during direct laryngoscopy.
During 2-person bag-mask ventilation, what is the role of the second rescuer?
Answer: Use both hands to maintain a proper mask seal while the first rescuer squeezes the bag
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.
What is the primary advantage of video laryngoscopy over direct laryngoscopy in ACLS?
Answer: It provides an improved indirect view of the glottis, particularly in difficult airways
Video laryngoscopy displays a magnified view of the glottis on a screen, improving first-pass success rates especially in anatomically difficult airways.
When waveform capnography is unavailable, what is the next best method to confirm ETT placement?
Answer: Colorimetric CO2 detector
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.
After ROSC, what is the recommended ventilation rate and PaCO2 target for post-cardiac arrest care?
Answer: 10-12 breaths/min targeting normocapnia (PaCO2 35-45 mmHg)
Post-ROSC guidelines recommend 10-12 breaths/min targeting normocapnia to avoid hyperventilation-induced cerebral vasoconstriction and hypocapnia.
Why does a drowning victim typically require higher ventilation pressures during ACLS resuscitation?
Answer: Decreased lung compliance from fluid-filled alveoli and pulmonary edema
Fluid-filled alveoli and pulmonary edema in drowning victims markedly reduce lung compliance, necessitating higher inflation pressures to achieve adequate tidal volumes.
What is the recommended post-ROSC oxygen saturation target to avoid both hypoxia and hyperoxia?
Answer: 94-99%
Post-ROSC SpO2 should be titrated to 94-99%; both hypoxia and hyperoxia have been associated with worse neurological outcomes after cardiac arrest.
