In asthma, lower end-tidal carbon dioxide may predict acute exacerbation outcomes, although other measures may be better severity indicators.

Adequacy of oxygenation is monitored; oxygen saturation, arterial blood gases, and end-tidal CO2 levels are measured and supplemental oxygen supplied (Hickey). Other nursing responsibilities ...

In general, the degree of unsaturation paralleled the degree of occlusion of pulmonary vessels as judged by post-mortem examination or by the magnitude of the arterial-end-tidal carbon dioxide ...
