What precautions should be taken before initiating hyperbaric oxygen therapy (HBOT)?

1. Eliminate all flammable products

2. Ensure the patient has fasted

3. Administer sedatives before treatment

4. Provide a heated blanket for comfort

The correct answer is: Eliminate all flammable products

Before initiating hyperbaric oxygen therapy (HBOT), one of the primary precautions is to eliminate all flammable products. This is crucial because the hyperbaric chamber operates under increased atmospheric pressure and is filled with pure oxygen, creating an environment that significantly heightens the risk of fire. Oxygen supports and accelerates combustion, so any flammable substances or materials present can lead to dangerous situations. Therefore, ensuring the chamber and surrounding area are free of flammables is a vital safety step to prevent potential fires and ensure patient safety during the therapy. Other options may seem relevant in certain contexts, but they do not address the immediate and critical safety issues related to the unique environment of HBOT. While fasting might be required for specific therapeutic reasons in other medical procedures, it is not a standard precaution necessary for HBOT. Sedatives are not typically administered for HBOT; rather, the focus is on patient safety and comfort without additional sedative effects. Providing a heated blanket may improve comfort, but it does not directly relate to the safety protocols that are fundamental before starting HBOT.
