I have performed spirometry on acute exacerbations of COPD during their hospital admission - no one came to any harm in performing full spirometry (insp and exp).
I think The question of Dr Colin was about performing Spirometry in Critical ill patients considers different groups other than AECOPD Dr Simon, So it includes patients with acute MI or Acute pulmonary edema or respiratory failure.
Hi, thank you all for your good answers. Yes I was interested in acute patients in general, but also in those with acute exacerbations of COPD. I will use spirometry with caution if I need to, and for those who have gotten better after an exacerbation, it should be safer to test the lung function.
As you know , patient cooperation and good maneuver is the major determinant of spirometry from the point of validity and reliability of test result. We have many acute illnesses , but in most of them clinical judgement and resort to other diagnostic methods is better than reliance on spirometry with doubtful results.In some situations spirometry may damage the patient instead of helping to him, eg acute myocardial infartion,,pneumonia, acute respiratory infections,......so in every patient visit ,we must remind the famous word of Dr Osler , please do no harm first.
In case you need such lung function measurements for research purposes, I would suggest you use forced oscillation technique, which is a sensitive and effortless procedure.
