What defines hypotension in infants?

Hypotension in infants is defined as a systolic blood pressure less than 70 mmHg. This threshold is important because infants have different blood pressure norms compared to older children and adults. In clinical practice, understanding these values is crucial for assessing the hemodynamic status of an infant. Blood pressure in infants is generally lower due to their smaller body size and the physiological differences in circulation.

The choice of less than 70 mmHg aligns with established pediatric guidelines, emphasizing the need for careful monitoring in this population to recognize and intervene in cases of compromised perfusion or circulatory status. Selecting the correct value ensures that healthcare providers can accurately identify hypotensive conditions and provide appropriate care to infants who may be at risk for serious health complications.
