Question

A newborn of 34 weeks gestation is not breathing ( apneic) at birth, does not respond to initial steps and requires positive-pressuer ventilation. what concentration of oxygen should be used as you begin positive-pressure ventilation?

Answer 1

The concentration of oxygen used for positive-pressure ventilation in a newborn of 34 weeks gestation should be between 21% and 30% to maintain oxygen saturation within the target range.

Step-by-step explanation:

When a newborn of 34 weeks gestation is not breathing at birth and requires positive-pressure ventilation, the concentration of oxygen used should be between 21% and 30%. The goal is to deliver enough oxygen to support the baby's breathing, but not to exceed the baby's physiological requirements to avoid potential harm caused by excessive oxygen exposure. This concentration range is based on the principle of titrating oxygen delivery to maintain oxygen saturation within the target range for the baby's age and clinical condition.

Answer 2

According to aafp.org, millions of infants use this method. If the heartbeat of an infant is less than 100bpm there should be a PPV using 21% of oxygen (room air) through a face mask, used for the infant using the flow-inflating bag, it can also be used in a self-inflating bag or a device. As for the procedure of its administration and procedure, you can ask a health professional.
