What is the recommended initial setting for the respiratory rate (f) for infants?

The recommended initial setting for the respiratory rate in infants typically falls within the range of 20 to 30 breaths per minute. This range is based on physiological norms for infants, as their resting respiratory rates are generally higher than those of older children and adults due to their increased metabolic demands and smaller lung volumes.

Respiratory rates for infants can vary depending on age and health status; however, the 20 to 30 breaths per minute range is appropriate for most situations in a clinical setting when initiating mechanical ventilation. It supports effective gas exchange while accommodating the delicate nature of an infant's respiratory physiology.

Setting the respiratory rate too low may lead to insufficient ventilation, resulting in inadequate oxygenation and carbon dioxide removal, whereas a rate that is too high may lead to hyperventilation and respiratory alkalosis due to excessive removal of carbon dioxide. Thus, starting within the recommended range ensures a balance that supports an infant's respiratory needs effectively.
