Nasal is a clinical biofeedback platform that gives orthotropic and airway-focused practitioners what the appointment can't: an ongoing record of what's actually happening between visits — with precise control over how, and when, the patient receives correction.
A patient opens the app on their tablet, taps a video they want to watch, and the front-facing camera tracks their face during the session. Mouth-open events are detected on-device — duration, peak jaw-open value, and yawn-likelihood logged for each. The intervention engine then delivers a graded response (silent log, gentle prompt, dim, pause) according to the patient's clinical phase and the active session template.
No video is recorded. No video leaves the device. Only the event data does.
Per-modality breakdown, performance and stability indices, session matrix heat map, multi-line trend charts, rule-based interpretation. See the patient's pattern at a glance, drill into any session.
Phase progression, intervention threshold, response mode, session templates, modality availability — all per-patient. Adjust based on what you observe; auto-advance with safeguards or manage manually.
Auto-drafted on phase transitions and on a 4-week cadence. You review, edit, and send. Plain-language, warm tone, clinician-voiced — never auto-sent.
If a patient goes quiet for several days, a gentle email goes to the parent. One per period. Configurable per patient. You stay focused on clinical decisions.
Habit change requires immediate, contingent, neutral feedback — feedback that arrives at the exact moment of the behavior, every time, without judgment, from a source the child has no relationship with.
A parent cannot deliver this. The clinician sees the patient briefly. Nasal closes that gap by being present at home, every day, neutral, and consistent.
A mouth-open event triggers exactly one of five graded intervention levels (A through E), decided by the patient's current clinical phase and the active template. Detection is invariant across levels — every event is logged with timestamp, duration, peak jaw-open, and yawn-likelihood, regardless of whether the child sees feedback.
Yawn detection (jaw-open + eye-squint + duration) suppresses intervention but not logging. Speech filter excludes brief openings below a configurable threshold. Block-structured templates (ABACA and similar) let you measure within-session retention as an explicit construct rather than an inferred one.
Phase progression is auto-advancing or manual; thresholds are configurable. You retain veto over every transition.
If you'd like to talk to someone before creating an account, leave your details and we'll be in touch. We'll send a short overview of how Nasal fits into a typical practice, and answer any specific questions you have about your patient population.
Nasal is designed for clinicians treating airway and breathing patterns: orthodontists, orthotropists, dentists, myofunctional therapists, speech-language pathologists, ENT and pediatric specialists collaborating on airway-focused care plans. It supplements, not replaces, your clinical judgment and in-person work.
Nasal is a clinical biofeedback prototype, not a medical device. It's used under your supervision, with your protocols, your decisions about progression, and your direct relationship with the patient and family.
