Summary:[...]this effect appears to be dose dependent. [...]lower levels or shorter durations of smoke exposure fail to significantly increase COHb levels [4]. Generally, exogenously delivered CO presents a half-life of 5 to 6 hours without supplemental oxygen administration [5]. [...]it is not surprising that COHb had poor discriminating ability for passive smoking in when evaluated later after the exposure during the preoperative process [6,7].
