WitrynaTable 1 shows the values of R in the presence of a shunt (V˙ a /Q˙ = 0) and in the presence of a low V˙ a /Q˙ ratio unit (V˙ a /Q˙ = 0.01) for gases of low, medium, and high partition coefficient, λ. The corresponding calculations for a high V˙ a /Q˙ unit and the dead space (infinite V˙ a /Q˙) are also shown. For the low solubility gas ( λ = 0.005), … http://downloads.lww.com/wolterskluwer_vitalstream_com/sample-content/9780781785891_Smeltzer/samples/Chapter021.pdf

Mechanisms of abnormal gas exchange in patients with pneumonia

WitrynaGas exchange can be impaired by several mechanisms. Insufficient carbon dioxide (CO 2 ) excretion leads to arterial hypercapnia, which can result from alveolar hypoventilation due to decreased respiratory frequency, as in drug-induced coma, diaphragmatic dysfunction, muscle weakness, and acute or chronic obstructive lung disease. WitrynaThe mechanisms of abnormal gas exchange in patients with pneumonia and the gas exchange response while breathing high inspired O2 concentrations have not been clearly elucidated. To this end, we studied 23 inpatients with pneumonia and mild to severe arterial hypoxemia and/or increased alveolar - arterial O2 difference. change back to bing
