Sleep apnea 101: symptoms, clinical testing, and where phone audio stops.

Sleep apnea is a medical condition evaluated with clinical history and appropriate testing. Obstructive and central forms involve different mechanisms; a bedside microphone cannot distinguish them or establish a diagnosis.

Polysomnography and qualified home sleep apnea testing use physiological signals and professional interpretation. SomniSense uses one phone microphone and has a different, narrower role.

Common symptoms are worth discussing, but they are not specific

The U.S. National Heart, Lung, and Blood Institute lists symptoms that may occur with sleep apnea, including frequent loud snoring, breathing that starts and stops, gasping, daytime sleepiness or tiredness, focus problems, and headache. Other conditions and circumstances can produce overlapping symptoms.

Recurring gasping, witnessed pauses, persistent tiredness, or another concern can be a reason to speak with a qualified clinician regardless of what a consumer app reports.

What clinical testing adds

Clinical pathways can measure signals such as airflow, oxygen saturation, respiratory effort, sleep state, heart activity, and movement, depending on the test. A professional interprets those signals alongside symptoms and history.

Cost, scheduling, insurance, availability, and timing vary by location and care pathway. That variability does not reduce the clinical authority of the test.

What SomniSense can add before or between conversations

You can start tonight with the supported phone already beside your bed. The app organizes candidate acoustic regions by model-estimated time, type, duration, marked waveform, available local audio, and whole-night position.

Repeated nights may create a useful wellness baseline or structured report. They do not become a diagnosis through repetition, and BRI is not clinical AHI.
