Title: Carbon Monoxide Poisoning from Kinjal Sethuraman Author: Michael Bond Carbon Monoxide is a odorless but deadly gas. It is important to note that CO has an elimination half-life and it varies under different conditions. When evaluating a patient, we can calculate backwards to determine the COHb level at time of exposure in an acute event. Carbon Monoxide Half-Life: Average elimination on room air: 5-6 hours 100% Oxygen: 70-130 minutes 100% Oxygen under hyperbaric conditions at 3 ATA: 23 minutes There is NO need to recheck COHb level again after initial level because it will be lower- (except in the case of Methylene Chloride exposure).
