Carbon Monoxide Poisoning.

Carbon monoxide is a colorless, odorless, highly toxic gas primarily produced through the incomplete combustion of organic material. Carbon monoxide binds to hemoglobin and other heme molecules, causing tissue hypoxia and oxidative stress. Symptoms of carbon monoxide poisoning can vary from a mild headache to critical illness, which can make diagnosis difficult.

Radial Arterial Lines Have a Higher Failure Rate than Femoral.

Introduction: Arterial lines are important for monitoring critically ill patients. They are placed most commonly in either femoral or radial sites, though there is little evidence to guide site preference.

Methods: This is an ambispective, observational, cohort study to determine variance in failure rates between femoral and radial arterial lines.
