Abstract
Acute experiments on anesthetized cats with additional resistive loads to inspiration and/or expiration revealed adequate changes in vascular bed resistance and blood flow rate in the phrenic artery. The increase in the phrenic artery blood flow during airflow resistive loading by 30–40 mm H2O was similar to the, changes previously found for inspiration of gas mixtures containing 5% O2 and 5% CO2. Minute ventilation increased 2 times under hypoxia and 3.5 times under hypercapnia. This index did not change under additional loading.
