During stage N2 sleep, if increased snoring and an increasing leak are noted, what should the technician do?

Repositioning and adjusting the Positive Airway Pressure (PAP) interface is the most appropriate action to take in response to increased snoring and an increasing leak during stage N2 sleep. This situation often indicates that the mask may not be fitting properly or the position of the patient has led to an increased tendency to obstruct their airway, which can cause leaks and result in snoring.

By adjusting the PAP interface, the technician can help ensure that it fits snugly against the patient's face, minimizing leaks and enhancing the effectiveness of the therapy. Proper mask fit is critical in maintaining the therapeutic pressure needed to prevent airway obstruction, thus improving the patient's sleep quality and reducing the incidents of snoring and leaks.

If the PAP interface is not adequately sealed, air can escape, resulting in insufficient pressure delivery and making it challenging for the patient to maintain stable breathing patterns during sleep. Therefore, ensuring an optimal fit is essential and can often resolve issues of increased snoring and leaks without the need for more drastic measures like increasing pressure or switching therapy modes.
