myAir Good Seal, but a Leak Email?

A leak email and a “good” mask-seal result can both appear in myAir. ResMed¹ explains that the overall result can look good even when parts of the night contain high leak. The reminder considers how leak values are distributed through the night.¹

Short leaks can hide inside the nightly summary

ResMed¹ names two possible situations: rolling over in bed and opening the mouth while wearing a nasal or nasal-pillows mask. Its guidance says the equipment provider may receive detailed seal and usage data and can take a closer look.¹

That gives you a specific request: “Can we review the leak pattern for this night, alongside the seal result and the email?” Ask whether the problem appears in brief episodes or continues for much of the session.

Add what you noticed when awake. “Air blew toward my left eye after I turned onto my side” describes a fitting problem more clearly than “the app is wrong.” If you do not remember waking, say that. You do not need to start watching the clock overnight to investigate a morning notification.

Record the mask model, size and recent changes

Write down the machine model, mask model and cushion size. Note whether you recently replaced the cushion, changed masks or reassembled the parts after cleaning. For a fitting appointment, ask which equipment the provider wants you to bring.

ResMed’s² fitting guidance lists incorrect adjustment, assembly or size, and worn components as possible leak causes. It recommends fitting in your usual sleeping position, because facial muscles change when you lie down and relax.²

If the mask fits while you sit upright but shifts when you lie on your side, demonstrate that position at the review. Tightening until the mask hurts is a reason to reassess fit. ResMed² warns against overtightening and notes that the cushion size may be wrong.² Follow the guide for your particular mask when making adjustments.

Know which airflow is meant to be there

Some air leaving the mask is intentional. For example, the AirFit N20 Classic guide explains that its vents allow incoming air to flush exhaled air out. It explicitly requires the vent holes to remain clear.³

Ask the provider to show you the vents on your model and distinguish their airflow from air escaping around the cushion. Do not cover the vents to silence the airflow or try to improve the score.³

Ask which leak measurement the report shows

If someone suggests a leak cutoff online, first establish which device and measurement they mean. The American Thoracic Society’s⁴ 2013 tracking statement documents differences in how manufacturers define leak and cautions about interpreting these data.⁴ Its historical comparison is not a current universal target for every machine.

Ask your provider which measure your report displays, what pattern needs action for your equipment, and how it fits with your symptoms and other treatment data. Have pressure-setting decisions reviewed by the sleep team rather than using an email as an instruction to change them.

The 14-Night Lights-Out Record in Did I Do That in My Sleep? organizes a brief morning account of sleep, daytime effects and the symptom being investigated. Add leak-related awakenings or discomfort if present. You can bring the observations you already have; completing fourteen nights is not a requirement for requesting help.
