II. Criteria: Hypotension
- Age under 1 year
- Systolic Blood Pressure below 70 mmHg
- Age 1 to 10 years
- Systolic Blood Pressure below calculated cutoff (70mmHg + 2 * ageYears)
- Age 11 years and older
- Systolic Blood Pressure less than 90 mmHg
III. Causes
-
Shock
- Hypovolemic Shock (Hemorrhagic Shock, Dehydration, Diabetic Ketoacidosis)
- Distributive Shock (Septic Shock, Neurogenic Shock, Anaphylaxis)
- Cardiogenic Shock (Congestive Heart Failure, Cardiomyopathy, Cardiac Contusion, valvular rupture)
- Obstructive Shock (Tension Pneumothorax, Pericardial Tamponade, massive Pulmonary Embolism)
- Non-shock states
- Other causes of Hypotension
- Acidosis
- Adrenal Insufficiency
- Hypocalcemia
- Hypothyroidism
- Thyroid Stimulating Hormone (TSH) may be initially normal despite severe Hypothyroidism or Myxedema Coma
- Consider empiric Hypothyroidism management when Bradycardia, Hypotension and Hypothermia are present

You've probably heard that high blood pressure is a problem. So what about low blood pressure? Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps out blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure. Your blood pressure reading uses these two numbers. Both are important. Usually they're written one above or before the other, such as 120/80. If your blood pressure reading is 90/60 or lower, you have low blood pressure. Some people have low blood pressure all the time. They have no symptoms and their low readings are normal for them. In other people, blood pressure drops below normal because of some event or medical condition. Some people may experience symptoms of low pressure when standing up too quickly. Low blood pressure is a problem only if it causes dizziness, fainting or in extreme cases, shock.
