Final answer:
TRUE, once Positive Pressure Ventilation begins, monitoring baby oxygen saturation with a pulse oximeter is necessary to ensure the newborn's well-being. This complements the Apgar score and helps guide immediate medical interventions.
Step-by-step explanation:
The statement is TRUE: Once Positive Pressure Ventilation (PPV) begins, an assistant should apply a pulse oximeter to assess baby oxygen saturation. Pulse oximetry is a non-invasive method to monitor the oxygen saturation level of the blood, which is crucial in determining a newborn's oxygen needs post-delivery and ensuring they are within a normal range (95-100%). Assessing the newborn with PPV is vital alongside traditional Apgar scoring, which evaluates five criteria: skin color, heart rate, reflex, muscle tone, and respiration at 1 and 5 minutes after birth. While a high Apgar score indicates a smooth transition from the womb, lower scores suggest the baby may require medical attention. PPV, along with pulse oximetry, helps in making timely decisions regarding the need for supplemental oxygen and further intervention.
