- Initial/Early
- Slight change to MAP
(5-10mm Hg)
- ▼ cardiac output (15%)
- Slight ▲ HR
- Switch from aerobic to
anaerobic metabolism
- ▲ lactic acid
- Slight change to MAP
(5-10mm Hg)
- Compensatory
- Activation of compensatory mechanisms
- Tachypnea,
tachycardia,
vasoconstriction
- ▼ MAP (10-15mm Hg)
- Continued ▼ cardiac
output (15-30%)
- ▼ MAP (10-15mm Hg)
- Tachypnea,
tachycardia,
vasoconstriction
- Activation of compensatory mechanisms
- Progressive
- Compensatory mechanisms fail
- Hypoperfusion
- ▼ cardiac
output
(30-40%)
- ▼ cardiac
