Validation study of a novel sleep Device compare to a traditional sleep study.

Sleep Apnea Syndromes
Sleep Disorder
Device: WatchPAT Intervention

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Masking Description:

Blinded to the subject’s diagnosis

Primary Purpose: Diagnostic

Official Title: Validation Study of the WatchPAT 200 in the Diagnosis of Obstructive Sleep Apnea in Children 4-12 Years of Age

Primary Outcome Measures:

Secondary Outcome Measures:

  • Peripheral arterial tone respiratory disturbance index (PRDI) [ Time Frame: At 104 Weeks ]

    Peripheral index from the device sensor as measured on the skin, similar to a pulse oximeter.

  • Oxygen desaturation index (ODI) [ Time Frame: At 104 Weeks ]

    Peripheral index from the device sensor similar to a pulse oximeter.

  • Sleep Staging and Sleep Time [ Time Frame: At 104 Weeks ]

    Overall sleep architecture parameters as reported on the Sleep Study PSG final report. Includes hyponogram and standard of care indices.

  • Oxygen saturation [ Time Frame: At 104 Weeks ]

    Amount of oxygen present in the subjects blood via pulse oximetry.

  • Heart rate [ Time Frame: At 104 Weeks ]

    Documentation of the Subjects heart rate.

  • Body Position [ Time Frame: At 104 Weeks ]

    Body position of sleeping subject to reflect upon overall sleep hygiene such as prone, supine, back, stomach, etc.

Estimated Enrollment: 60

WatchPAT Intervention

Wearing the WatchPAT device simultaneously while receiving a clinically indicated sleep study (polysomnogram).

Device: WatchPAT Intervention

Wearing the device during their clinically indicated sleep study. This is a validation study to the gold-standard polysomnogram.

This is an investigator-initiated validation study for the WatchPAT 200 device compared to the gold standard polysomnography procedure (sleep study). To evaluate the accuracy of the WatchPAT device compared to an in-laboratory Polysomnogram (PSG), measurements including obstructive apnea hypopnea index (OAHI), apnea hypopnea index (AHI), oxygen desaturation index (ODI) and other relevant sleep parameteres and indices will be compared. Ultimately, the diagnostic agreement of the WatchPAT device in detecting between normal sleep and mild sleep apnea architecture will be assessed.

Ages Eligible for Study:   4 Years to 12 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  1. Age 4 through 12 years of age.
  2. Referral to the Sleep Lab due to concerns for Obstructive Sleep Apnea (OSA) and presenting with symptoms such as:

    • snoring,
    • witnessed apneas,
    • daytime sleepiness, and
    • mouth breathing, etc.
  3. Informed consent obtained.

Exclusion Criteria:

  1. Medical conditions that can affect the tonometer reading such as:

    • peripheral vascular disease,
    • cyanotic heart disease,
    • systemic hypertension, and
    • sickle cell crisis.
  2. Medical conditions that can potentially limit tolerance of the WatchPAT 200 device such as:

    • autism spectrum disorder,
    • Trisomy 21, and
    • neurodevelopmental disorders.
  3. History of neuromuscular or craniofacial malformation
  4. History of current supplemental oxygen use
  5. History of current vasoactive, cardiac or seizure medication use
  6. Inability or unwillingness to provide informed consent
