In addition to supplemental oxygen, what is a concern for casualties with suspected smoke inhalation?

Impaired oxygenation is a significant concern for casualties with suspected smoke inhalation because the inhalation of smoke can lead to the presence of toxic gases and particulate matter, which can severely compromise respiratory function. When a casualty inhales smoke, the airways can become inflamed and obstructed, potentially causing bronchoconstriction and reducing the lungs' ability to effectively transfer oxygen into the bloodstream. Furthermore, harmful substances found in smoke, such as carbon monoxide, can bind to hemoglobin more readily than oxygen, which can significantly decrease oxygen availability in the body. This impairment can lead to hypoxia, resulting in vital organs not receiving the oxygen they need to function properly, thus necessitating immediate attention to oxygenation in the treatment plan. The addition of supplemental oxygen is used to mitigate this risk, but understanding the underlying concern of impaired oxygenation is essential in properly managing the patient’s condition.
