Emphysema & Pulmonary fibrosis
,Which gas law applies to body plethysmography when temperature is constant and
you have a change in volume and pressure?
Give this one a try later!
Boyle's
Three days later the patient has stabilized and the physician asks you to help interpret
the pulmonary function test results and the arterial blood gas results. The results are
as follows:
ABG results on room air: pH: 7.36, PCO2: 59 mmHg, HCO3-: 36 mEq/L, PO2: 62mmHg
Interpret the blood gas:
