For an infant, what is the normal diastolic blood pressure?

The normal diastolic blood pressure range for infants is indeed between 37 and 56 mmHg. This range is based on the understanding that blood pressure values in infants differ significantly from those of older children and adults due to their smaller vascular systems and different physiological characteristics.

In clinical practice, knowing the normal ranges for diastolic blood pressure is crucial in assessing an infant's cardiovascular health. Blood pressure readings that fall within this range indicate adequate perfusion and systemic circulation in infants. Diastolic blood pressure represents the pressure in the arteries when the heart is at rest between beats, and a normal level helps ensure that organs receive proper blood flow at rest.

Values outside this range could suggest various medical conditions. For example, lower diastolic pressures may indicate shock or dehydration, while higher readings could be indicative of increased systemic vascular resistance or other underlying issues.

Understanding these normal ranges aids healthcare providers in recognizing potential problems early and making informed decisions about interventions when necessary.
