Various parameters including COHb were measured using a blood gas analyzer\/oximeter at the time of admission, with sampling of arteries and veins performed at short intervals (within 30\u2009min).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The arterial COHb values were significantly higher in group C than in group S. The a\u2010vCOHb values were significantly higher in groups C and M than in group S. This suggested that a loss of carbon monoxide excretion due to the generation of shunt blood with lung collapse at the alveolar level and a decrease in the total amount of carbon monoxide generated within the lungs resulted in the decrease of a\u2010vCOHb values in group S. Receiver operating characteristic curve analysis of a\u2010vCOHb for predicting the need for respiratory support identified an a\u2010vCOHb cut\u2010off value of 0.3% with a sensitivity of 75% and specificity of 74% (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n
