Low Blood Pressure
Alternate Names : Hypotension
How is the condition diagnosed?
Blood pressure is usually measured with a tool called a blood pressure cuff. Other special devices are sometimes used. Diagnosis of the cause starts with a history and physical exam. This may be all that is needed to determine the cause in some cases.
In other cases, further tests are needed. For example, a complete blood count, or CBC, can help diagnose infections. Low oxygen in the blood can be detected by arterial blood gases. A heart tracing, or ECG, can help diagnose abnormal heartbeats. A chest x-ray can help diagnose pneumonia.
