WatchPAT - Simple Sleep Health Management

The fragmented, disturbed sleep of many middle-aged adults can often be the result of sleep apnea, one of the most dangerous of all sleep disturbances. OSA (Obstructive Sleep Apnea) causes a person’s breathing to be interrupted during sleep, leaving a person momentarily choking and gasping for air. This may occur hundreds of times during sleep, which deprives the brain and other vital organs of life-sustaining oxygen.

In the USA and western countries, the prevalence of OSA is approx.

4% of adults males and 2% of females

Approx. 10% of infants and 2-4% of children suffer from OSA.

OSA is related to

What is sleep apnea?

Sleep apnea is a serious, potentially life-threatening sleep-related breathing disorder that is often linked with loud, heavy snorers. The more common form of sleep apnea is triggered by an obstruction in the upper airway (OSA - Obstructive Sleep Apnea), which decreases the amount of inhaled air, collapsing the tissue in the back of the throat, and disrupting sleep. Patients with OSA experience repetitive episodes of obstruction of the upper airway during sleep, typically last 20 to 40 seconds. An episode of partial airway closing is called a sleep hypopnea. With no air flowing into the lungs, oxygen levels drop and carbon dioxide levels rise in the blood. The reduction in oxygen and increased carbon dioxide alert the brain to resume breathing and cause an arousal. Finally, the patient awakens with a jolt and resumes breathing, and quickly falls back to sleep — and usually resumes loud snoring.

What are the common symptoms OSA?

It is estimated
that over 80% of
sleep apnea patients
remain undiagnosed!
Common symptoms of obstructive sleep apnea (OSA) include:
- Loud, intermittent snoring
- Awakenings due to gasping or choking
- Restless sleep
- Unexplained daytime sleepiness
- Morning headaches
- Insomnia
- Mood changes
- Sore throat or dry mouth
- Unexplained weight gain
- Heavy night sweats
- Decreased libido
- Frequent heartburn or GERD (gastroesophageal reflux disease)
- Increased heart rate and/or blood pressure
- Increased urination and/or nocturia
- Memory impairment
- Erectile dysfunction

Possible complications of Obstructive Sleep Apnea (OSA)

Snoring is considered a major indicator of OSA, and risk factors include obesity, age, neck size, gender, family history and anatomic abnormalities. Untreated sleep apnea is a major independent risk factor contributing to:
- Hypertension
- Cardiovascular disease
- Restless sleep
- Stroke
- Atrial Fibrillation
- Cognitive impairment
- Excessive Daytime sleepiness (EDS)
- Depression
- Impotence
- Motor vehicle accidents (MVA’s)
- Increased mortality
- Obesity
OSA is also associated with headaches, memory loss, mood changes, relationship disturbances and decreased libido.

What are the options to diagnose sleep apnea?

There are two diagnosis options:

  • Home Sleep Test (HST) devices, such as the WatchPAT

    WatchPAT is an FDA cleared portable homes sleep test system that diagnose sleep related breathing disorders. It is a small wrist mounted device which allows testing to be done in the comfort of patient’s own home. WatchPAT uses the most innovative technology (PAT signal) to ensure the accurate screening, detection, and follow-up treatment of sleep apnea. It is easy to use, provides fast results in an immediate comprehensive automatic report. The WatchPAT consistently demonstrates a high degree (up to 90%) of correlation as compared with PSG.

  • Sleep lap - Polysomnography (PSG)

    Polysomnography (PSG), cosidered the gold standard test, is used to diagnose a variety of sleep disorders or when further investigation is needed or in rare cases, such as central or mixed apnea is suspected. PSG is performed at a sleep disorders center within a hospital or at an independent sleep centers.
