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)
