CLINICAL DIAGNOSTIC MANUAL
Severe hypotension is a condition where blood pressure is abnormally low, leading to insufficient perfusion of vital organs. This condition can present acutely or chronically and may be caused by various factors, including cardiac issues, blood volume loss, vascular alterations, and endocrine disorders. Rapid identification and treatment are crucial to prevent serious complications such as shock and organ failure.
Pathology | Suspected Diagnosis | Confirmatory Diagnosis |
Low cardiac output | Hypotension, dyspnoea, fatigue, peripheral oedema. | Echocardiogram, blood tests (BNP, troponins). |
Decreased circulating volume | Hypotension, tachycardia, pale and cool skin, oliguria. | Complete blood count, electrolytes, abdominal ultrasound, urine analysis. |
Loss of vascular tone | Hypotension, tachycardia, signs of shock, warm and moist skin. | Clinical history, autonomic function tests, blood tests. |
Addison’s disease | Hypotension, hyperpigmentation, fatigue, weight loss. | Cortisol and ACTH levels, ACTH stimulation test. |
Spinal cord injury or disease | Hypotension, loss of motor or sensory control below the level of the injury. | MRI or CT of the spine, neurological examination. |
