T58.93

Clinical Causes: Intentional exposure during assault or violence involving the deliberate release of carbon monoxide Accidental inhalation of carbon monoxide from sources such as malfunctioning furnaces, heaters, or vehicle exhaust Use of charcoal grills or portable generators in enclosed spaces Leaking gas appliances leading to the accumulation of carbon monoxide indoors Structural fires producing carbon monoxide as a byproduct

Key Symptoms: Headache and dizziness Weakness and fatigue Shortness of breath Confusion or altered mental state Nausea and vomiting Loss of consciousness in severe cases Cherry-red skin coloration (less common but notable when present)

Diagnosis Path: Diagnosis is typically based on clinical history, especially exposure to sources of carbon monoxide, combined with physical examination findings. Confirmatory tests include blood tests that measure carboxyhemoglobin levels, which indicate the amount of carbon monoxide bound to hemoglobin in the blood. Additional investigations may include pulse oximetry, arterial blood gas analysis, and chest X-rays to assess any associated injuries or complications.

Treatment Protocols: Administering 100% oxygen through a mask to displace carbon monoxide from hemoglobin Hyperbaric oxygen therapy in severe cases, which involves breathing pure oxygen in a pressurized chamber to hasten the removal of carbon monoxide Supportive care, including monitoring vital signs and neurological status Treating any associated injuries or complications, such as burns or trauma Preventative measures to eliminate sources of carbon monoxide and improve ventilation
