End-Tidal Carbon Dioxide as a Measure of Carboxyhemoglobin in Carbon Monoxide Poisoning

End-Tidal Carbon Dioxide as a Measure of Carboxyhemoglobin in Carbon Monoxide

The purpose of this study is to determine whether a relationship exists between EtCO2 and carboxyhemoglobin levels in carbon monoxide exposure. Our hypothesis is that a liner relationship exists between EtCO2 and carboxyhemoglobin in carbon monoxide poisoning.

Inclusion Criteria:

• Carbon monoxide exposure

Exclusion Criteria:

• Less than 18 years old
• Suicide attempt
• Unable to provide informed consent
