Explain diffusion of oxygen and its physio mechanism and how it can be used to measure the diffusing capacity of an ill patient with shortness of breath, fever, sputum with cough. Which conditions of the vital signs are probably affecting the impaired diffusion mechanism.
Vital Signs. TA 110/70mmHg HR 110bpm RR 25rpm Temp 39 C (102.2 F) Pulse Oximetry 83%
Lung auscultation crackles in right subscapularis and egophony. Dehydrated and disoriented.
