What is PEEP and why is it used during neonatal PPV?
Answer: Positive end-expiratory pressure; maintains lung volume between breaths
PEEP maintains functional residual capacity between breaths, preventing alveolar collapse especially in preterm lungs.
A newborn receives 30 seconds of PPV with no improvement in heart rate. What is the next step?
Answer: Verify adequate chest rise and apply MR SOPA if needed
If heart rate does not rise after 30 seconds of PPV, the provider must verify chest rise and apply MR SOPA corrective steps before escalating.
What is the recommended mask size for PPV in a term newborn?
Answer: A mask that covers the mouth and nose but not the eyes
The mask should cover the mouth and nose completely but not extend over the eyes, to ensure an adequate seal without pressure on the eyes.
Which type of resuscitation device does NOT require a compressed gas source to deliver PPV?
Answer: Self-inflating bag
A self-inflating bag reinflates automatically after each compression and does not require a compressed gas source, making it available in any setting.
When can free-flow oxygen be delivered with a self-inflating bag?
Answer: It cannot deliver free-flow oxygen reliably
A self-inflating bag does not deliver reliable free-flow oxygen because the inlet valve remains closed unless the bag is squeezed.
A gastric tube should be inserted during prolonged PPV primarily to:
Answer: Prevent stomach distension that can impair ventilation
Prolonged bag-mask ventilation can inflate the stomach, causing diaphragmatic elevation and compromising lung expansion.
