Study Notes
Shock
- Shock is a condition of inadequate blood flow and oxygen delivery to body tissues.
- Shock can be classified as:
- Hypovolemic shock (loss of blood volume)
- Cardiogenic shock (decreased cardiac output)
- Distributive shock (massive vasodilation)
- Neurogenic shock (generalized vasodilation)
- Septic shock (severe infection)
- Anaphylactic shock (severe allergic reaction)
Compensatory Mechanisms in Shock
- Body tries to compensate for shock through various mechanisms:
- Sympatho-adreno-medullary response (SAMR):
- Increased heart rate and blood pressure (BP)
- Increased cardiac contractility and output
- Antidiuretic hormone (ADH) release:
- Promotes water retention and BP maintenance
- Arteriolar vasoconstriction
- Renin-angiotensin-aldosterone system (RAAS):
- Angiotensin causes vasoconstriction to maintain BP
- Aldosterone helps maintain sodium and water balance, increasing circulating volume and BP
- Sympathetic nervous system (SNS) stimulation:
- Norepinephrine release
- Increased BP
- Sympatho-adreno-medullary response (SAMR):
