- Differentiate between the pulmonary and systemic circulations with respect to: total flow rate, blood volume, vascular compliance, vascular pressures, total vascular resistance, and response to hypoxia.
- Differentiate among zones 1, 2, 3, and 4 in the lung with respect to the relationship among pulmonary vascular pressures (arterial and venous), airway pressure, and patterns of pulmonary blood flow.
- 9.3: Zones of Perfusion
- We now have to consider the relationship of the pressures in these three systems, arterial, alveolar and venous at different heights of the lung. Many of the following principles have already been dealt with, but we can put them together to look at how they effect perfusion distribution.
