Overview

Hypotension means low blood pressure (BP). A systoloc BP measuring less than 90mmHg and/ or diastolic BP of less than 60mmHg is considered hypotension.

Causes

Life Threatening Causes

Life-threatening causes include conditions that result in death or permanent disability within 24 hours if left untreated.

Common Causes

The algorithm illustrates common causes of hypotension based upon the etiology.[1][2][3][4]

Do's

  • Educate the patient to avoid predisposing conditions such as dehydration, alcohol, etc.
  • Discontinue or adjust the dose of medication if hypotension is caused by medication side effects.
  • Advice to wear compression stockings to relieve the pain and swelling from varicose veins.
  • Counsel the caregivers of elder patients with postprandial hypotension.

Don'ts

  • Do not over treat hypotension. Symptomatic low BP or decreased organ perfusion is a treatable entity.
