Final answer:
Hypotensive for a patient aged from birth to 1 month refers to a blood pressure value below the normal range for this age group, which can result in insufficient blood flow to tissues. Various factors can contribute to hypotension in newborns.
Step-by-step explanation:
For a patient aged from birth to 1 month, hypotensive would be considered a blood pressure value below the normal range for this age group. Normally, the mean arterial pressure (MAP) falls within the range of 70-110 mm Hg. If the value falls below 60 mm Hg for an extended time, it could result in insufficient blood flow to the tissues, leading to ischemia and hypoxia. Hypotension in newborns can be caused by various factors such as prematurity, infection, or cardiac abnormalities.
