Hi folks,Let me ask you about this, because people I've talked to disagree.There was a patient admitted with a problem, probably related to IBD, with severe diarrhea, fever, vomiting. Everything but the diarrhea was brought under control, but the doctors were kind of baffled as to what was causing all the problems. Prednisone and IV antibiotics were prescribed. After a day or two the patient developed intermittent chest congestion with severe coughing. The doctors didn't know what it was -- chest X-ray showed nothing. While sleeping, sats at one point dropped to about 85 or 86. The patient wasn't in any particular distress, and sats started rising slowly now that the patient was awake, getting up around 90. Still, there was a lot of chest congestion. I don't know if the patient showed any cyanosis, but I doubt it. Blood pressure was unremarkable, pulse was a little high, maybe 100.Should oxygen be given? What are your thoughts? The congestion would come and go. All things equal, I would prefer to give oxygen, but am I missing something?
