Low blood pressure 90/50 is dangerous.

Hypotension of 90/50mmHg refers to systolic blood pressure of 90mmHg and diastolic blood pressure of 50mmHg. Whether this phenomenon is dangerous needs to be analyzed according to the actual situation.

Systolic blood pressure of 90mmHg and diastolic blood pressure of 50mmHg are within the range of hypotension, but whether this situation is dangerous needs to be judged according to the actual situation. If hypotension is related to physiological factors, such as excessive weight loss, sudden standing, etc., and the patient has no other discomfort symptoms, there is usually no danger. However, if hypotension is related to pathological factors such as infection, massive hemorrhage, acute myocardial infarction, etc., or if hypotension lasts for a long time, it may affect the blood perfusion of various organs and tissues of the whole body, and the situation is relatively dangerous at this time.
