The effectiveness of sympathomimetic amines on heart and circulation is diminished in acidosis. This diminution is most significant in those animals (cat, pig) with the most augmented sympathetic tonus in acidosis, but experiments performed with reserpinized cats indicated that the augmented sympathetic...
Respiratory acidosisis characterized by a decrease in pH and an increase in Pco2, which develop because of decreased effective alveolar ventilation. CO2diffuses through the lungs much more readily than oxygen; thus diseases that compromise ventilation normally result in decreases in PO2before significant...
To test the participation of the carotid bodies in the respiratory response to , six were infused with HCl for 2 h followed by HCl feeding to prolong the to 48 h. This protocol was repeated after carotid body denervation (CBD). Mean control PCO2 rose by 7.3 Torr after CBD. PCO2 fell co...
Distribution of H+ and HCO3- between CSF and blood during respiratory acidosis in dogs To evaluate the regulation of (H+) and (HCO3 minus) in brain extracellular fluid during respiratory acidosis, the changes in cisternal and lumbar CSF acid-base state were assessed in six anteshetized, paraly...
Apparent breathing difficulty caused by non-respiratory conditions can occur in association with severe pain, acidosis (eg, Kussmaul respiration associated with diabetic ketoacidosis), anemia, drug administration (eg, opioids), shock, and hypotension. ...
1.AnatomyA muscular membranous partition separating the abdominal and thoracic cavities and functioning in respiration. Also calledmidriff. 2.A membranous part that divides or separates. 3.A thin disk, especially in a microphone or telephone receiver, that vibrates in response to sound waves to pro...

We tested the hypothesis that a more intense acidosis of the external oblique relative to the diaphragm may be the signal that determines the differential inhibitory opioid-mediated effect upon the respiratory muscles during . Unanesthetized were exposed to (50 cm /1/s) for 120 min, before and...
Determines whether a respiratory acidosis would occur, whether it would be compensated for, and whether these responses would be related to the ability of the sea urchin to osmoregulate. Determination of the volume of fluid lost during emersion; Measurements of chloride, calcium, ammonia, lactate,...
Fetal femoral arterial blood gases remained similar to control levels during and after the stimulation although there was a gradual development of an acidosis with increasing length of time following exteriorization. There was no correla- tion between fetal arterial blood gases and pH and the ...
