Case #1
Mrs. G, a 62-year-old female, was seen in the emergency department for complaints of increasing shortness of breath. Mrs. G states that seven years ago her family physician told her she had emphysema.
At home she is on oxygen via nasal cannula at 1 lpm, and a small volume nebulizer with albuterol sulfate four times a day. Her vital signs are as follows: HR 108/minute, RR 28/minute, BP 142/80 mmHg.
ABG results on a 24% venturi mask are:
pH 7.32
P a CO 2 62 mmHg
P a O 2 50 mmHg
HCO 3 30 mEq/l
S a O 2 85%
BE +5
Hb 13g/dl
ETCO2 30 mmHg
P B 740 mmHg
