Final answer:
The appropriate ventilation rate during PPV is typically 10 to 12 breaths per minute for adults, while newborns and infants require a higher rate of 30 to 60 breaths per minute.
Step-by-step explanation:
The ventilation rate to be used during Positive Pressure Ventilation (PPV) depends on the age and the clinical scenario. However, for adults, a typical ventilation rate is usually between 10 to 12 breaths per minute and must synchronize with the patient's effort to avoid hyperventilation or hypoventilation. In contrast, a newborn or an infant requires a higher respiratory rate ranging from 30 to 60 breaths per minute. The goal of PPV is to ensure that the volume of air per breath and the respiratory rate are adjusted to maintain adequate alveolar ventilation and prevent carbon dioxide buildup.
