Biphasic ventilatory response to hypoxia in unanesthetized rats.
To determine the role of postinspiratory inspiratory activity of the diaphragm in the biphasic ventilatory response to hypoxia in unanesthetized rats, we examined diaphragmatic activity at its peak (DI), at the end of expiration (DE), and ventilation in adult unanesthetized rats during poikilocapnic hypoxia (10 % O2) sustained for 20 min. Hypoxia induced an initial increase in ventilation follo...
متن کاملVentilatory response of the unrestrained and unanesthetized hamster to CO2.
T WAS OBSERVED in this laboratory that in I a closed chamber containing a man the pressure increases on inspiration due to the wetting and warming of the air. It was suggested to the author that this principle might serve as a method for the measurement of respiration in small animals where it is difficult to make use of masks and where immobilization by anesthetics or by physical restraint is ...
متن کاملVentilatory response to hypoxia in experimental pathology of the diaphragm.
In this study, we examined the usefulness of arterial blood gas variables, as changed by the hypoxic stimulus, in discerning various experimentally-induced conditions of diaphragm weakness in anesthetized cats. We defined three experimental situations (models): (i) intact muscle, statistical Class I, (ii) four degrees of muscle dysfunction (after sequential diaphragm denervation), Classes II-V,...
متن کاملAlveolar hypoxia increases lung fluid filtration in unanesthetized newborn lambs.
We studied the pulmonary vascular response to hypoxia and associated transvascular flux of fluid into the lungs of newborn lambs. After a 2-hour baseline period, 14 unanesthetized lambs, 1-3 weeks old, breathed 10-12% oxygen in nitrogen for 3-6 hours. We measured steady state lung lymph flow, pulmonary arterial and left atrial pressures, blood flow to the lungs, and the concentration of protein...
