Which of the following is not a precaution to take when using home oxygen therapy?

When using home oxygen therapy, it is crucial to avoid using petroleum products near the face because these products are flammable and can ignite in the presence of an oxygen-rich environment. This can pose a significant fire hazard, particularly for patients who are using oxygen therapy, as the increased concentration of oxygen can accelerate combustion.

In contrast, keeping 100% cotton bedding is advised because cotton is a safer fabric choice; it is less likely to ignite compared to synthetic materials. Ensuring that hand sanitizer is completely dry before coming into contact with oxygen is also important, as the alcohol in hand sanitizer can be flammable. Limiting the length of the oxygen tubing to 50 feet helps to ensure that the flow of oxygen remains effective and reduces the risk of kinks or blockages that can occur in longer tubing.

Thus, avoiding petroleum products when using oxygen therapy is essential for safety, whereas the other options represent effective precautions that align with best practices for oxygen use at home.
