Accuracy of Medical Oxygen Flowmeters: A Multicentric Field Study
août 2014, HE CondorcetArticle scientifiqueThe accuracy of 476 oxygen flowmeters was investigated using a thermal mass flowmeter in eight hospitals in France and Belgium. Different oxygen flow rates (2 to 15 l/min) were evaluated at the patient’s bed. When the sample was considered as a whole, the accuracy of delivered flow was acceptable but precision was poor. The variability of the delivered flow between devices was greater when a low ...
