<prompt> Regarding carbon monoxide poisoning, the wrong statementOxygen dissociation curve shifted to rightOxygen dissociation curve shifted to leftCOHb is formedHyperbaric oxygen can be used  <response>: Since Hb has more affinity to CO than oxygen, it results in anaemic hypoxia. PO2 remain normal as it is the dissolved form. Hb-O2 dissociation curve shifts to left. Treatment for CO poisoning is by hyperbaric oxygen. But 95 O2 5 CO2 can also be used. CO is a gaseous vasodilator.
