About

Carbon monoxide (CO) poisoning is a condition that occurs as a result of inhaling carbon monoxide gas and can potentially lead to serious health issues. The treatment of CO poisoning requires urgent medical intervention. Methods used in the treatment of CO poisoning include normobaric oxygen (oxygen at normal pressure), high-flow oxygen, non-invasive continuous positive airway pressure (CPAP), and hyperbaric oxygen therapy. Studies on these methods are available in the literature.

Full description

When examining the mechanisms of application for these methods:

Normobaric Oxygen Therapy: In normobaric oxygen therapy, researchers treat participants with normobaric (sea level) oxygen. This method provides high concentrations of oxygen, allowing better oxygen saturation of the blood and faster removal of carbon monoxide from the body. Participants inhale normobaric oxygen through devices such as masks or nasal cannulas.

High-Flow Oxygen Therapy: In high-flow oxygen therapy, researchers treat participants with high-flow oxygen. Typically, a nasal cannula or oxygen mask is used. The high flow rate allows more oxygen to reach the alveoli and bind to hemoglobin. This method can be effective, especially in more severe cases of carbon monoxide poisoning.

Non-Invasive CPAP Therapy: Non-invasive CPAP therapy is typically used to treat respiratory problems such as sleep apnea but can also be used in the treatment of CO poisoning. Participants receive oxygen under continuous positive airway pressure with the help of a mask.

Comparison of these methods:

Normobaric oxygen is considered the standard treatment for CO poisoning and generally effectively eliminates carbon monoxide from the body. High-flow oxygen may be more effective in providing additional oxygen in more severe cases, but it works similarly to normobaric oxygen. The choice of which treatment method to use can vary depending on the participant's clinical condition, the severity of poisoning, and other factors. The researchers main goal in designing this study is to determine which treatment, depending on the researcher's decision, most rapidly shortens the half-life of carbon monoxide in participants experiencing severe carbon monoxide poisoning.The researchers aim to identify which treatment participants tolerate better and which method minimizes complications related to CO intoxication.
