Abstract

A study was made of the respiratory effects of acute carbon monoxide poisoning in mongrel dogs. In this study the dogs were divided into two groups, namely the control and the experimental. In the experimental group, carbon monoxide poisoning was induced by the rebreathing of about 2% carbon monoxide gas mixture for 15 minutes, and the respiratory functions in this group were compared to those in the control group.

A significant increase in the minute ventilation was noted in both the control and the experimental groups, and in the latter there was an increase in the respiratory rate and a decrease in the tidal volume compared to those in the control group.

In both groups, oxygen consumption showed no significant change and there was a fall in the arterial carbon dioxide tension, but the carbon dioxide elimination was slightly lower in the experimental group.
