PPV should be administered at a rate that is close to the patient's normal respiratory rate, which is 12 to 15 breaths per minute for adults, and higher for children depending on their age.
When giving breaths via Positive Pressure Ventilation (PPV), there is no one-size-fits-all rate, as it depends on the patient's age and condition. However, for adults, breaths with PPV are typically given at a rate near the average respiratory rate of 12 to 15 breaths per minute, although specific situations might call for different rates.
For children, this rate is higher, reflecting their naturally higher respiratory rates which can range from 30 to 60 breaths per minute for infants and 18 to 30 breaths per minute for older children. The goal of PPV is to ensure that adequate ventilation is maintained to prevent carbon dioxide buildup and provide sufficient oxygen delivery, thus the rate may be adjusted based on the patient's oxygenation status and blood gas levels.
