Definition
Hypotension is low blood pressure, especially in the arteries of the systemic circulation. It is considered to be a systolic BP of less than 90mmHg or diastolic of less than 60mmHg.
Causes
Life Threatening Causes
Common Causes
- ACE inhibitors
- Addison's disease
- Alpha blockers
- Anaphylaxis
- Beta blockers
- Bleeding
- Calcium channel blockers
- Diabetes mellitus
- Diuretics
- Hypoglycemia
- Hypothermia
- Hypovolemia
- Pregnancy
- Sepsis
- Shock
- Tricyclic antidepressants
Management
Algorithm summarizing the management of hypotension is shown below
