Under what condition would positive pressure ventilation (PPV) be indicated for an infant?

HR less than 60
HR less than 100
Assess breathing effort
Signs of respiratory distress

The correct answer is: HR less than 100

Positive pressure ventilation (PPV) is indicated in an infant when their heart rate is less than 100 beats per minute. This is important because a heart rate below 100 in an infant often suggests inadequate ventilation or inadequate oxygenation. In such cases, PPV is employed to ensure that the infant is receiving sufficient oxygen, which can help to stimulate the cardiac function and improve overall circulation. In clinical practice, if the heart rate falls below this threshold, it's crucial to assess the infant’s ventilation status and provide supportive measures, such as PPV, to establish or improve adequate breathing. Ensuring airway patency and delivering positive pressure can help to initiate or re-establish normal respiratory function, ultimately allowing the infant to stabilize or recover.
