Undifferentiated Hypotension Algorithm (Morchi)
Check:
- HR (age appropriate)
- <40 and >150-180 --> likely HR = Primary etiology
- Pace or Shock
- Volume Status - LVEDP (approx by CVP, IVC, etc.)
- History of volume loss
- Lung Exam
- Mucous membrane
- Ultrasound IVC (RUQ window or AAA)
- Hemeacuu, Guaic
- Contractility (weak heart)
- Bounding/thready pulse, hyperdynamic precordium
- Cardiac Ultrasound
- Low SVR - Vasodilation is the final answer, if all else is negative expect bounding pulse
Lack of Response to Normal Tx (DDX)
- Cardiac tamponade
- Tension PNTX
- Adrenal insuffic
- Toxin
- Allergic Rx
- Occult bleeding (ectopic, A/P)
- PE
- DIC
