Study Notes
Central Perfusion
- Requires adequate cardiac output, blood pressure, and blood vessel diameter
- The force of blood movement is generated by the heart's pumping action
Consequences of Inadequate Central Perfusion
- Inadequate oxygen delivery to tissues
- Accumulation of waste products
- Cellular damage and even death
Tissue/Local Perfusion
- Requires adequate capillary blood flow and permeability
- Associated with the delivery of oxygen and nutrients to tissues
Impairment of Tissue/Local Perfusion
- Involves inadequate oxygen delivery to tissues, leading to cellular damage and death
- Associated with the accumulation of waste products
Cardiac Output (CO)
- Calculated using the formula: CO = Heart Rate (HR) x Stroke Volume (SV)
