Carbon monoxide poisoning: assessment and actions for nurses working in service users' homes.

Abstract

Carbon monoxide is a colourless, tasteless and odourless gas that is a by-product of incomplete combustion of hydrocarbons such as gas or coal. Carbon monoxide poisoning is associated with high levels of mortality and morbidity, although the symptoms of exposure are non-specific and difficult to diagnose. Historically, healthcare professionals who work directly in service users' homes have faced a higher risk of exposure to environments contaminated with carbon monoxide. Despite improved heating engineering and greater protective legislation, there still remains a tangible risk for community nurses and service users, particularly in homes still using open fires, old heating systems and poorly maintained heating appliances. This article provides a scientific summary of carbon monoxide poisoning for nurses working in the community setting. It outlines evidence-based guidance on prevention and initial treatment actions, along with safety instructions to follow in the event of exposure to carbon monoxide.
