Which of the following is a potential side effect of BiPAP?

Pressure ulcers are indeed a potential side effect of BiPAP therapy. This occurs due to prolonged contact and pressure from the mask on the skin, particularly when the patient is using the device for extended periods. The mask creates localized pressure, which can impede blood circulation and lead to skin breakdown.

Maintaining the integrity of the skin is crucial, especially in areas where the mask interfaces with the face, such as the nose and cheeks. Regular assessment of the skin beneath the mask, along with appropriate measures like repositioning the mask and ensuring it fits properly without excessive tightness, can help mitigate the risk of developing pressure ulcers.

In contrast, while other options listed may occur in different contexts or with different treatments, they are not typically direct side effects associated with the use of BiPAP. Ear infections, for instance, are not commonly connected to BiPAP use, while nausea could arise from various causes unrelated to this specific therapy. Headaches might stem from factors like improper mask fit or pressure settings, but the risk of pressure ulcers is more directly related to the continuous nature of BiPAP therapy where skin integrity is at stake.
