SomnoWatch Plus


• SOMNOWATCH is a tremor analysis it is digital accelerometer , ambient light sensor. It is determination of light and high frequency amplitude it has the graphic representation frequency and intensity of whole measurement.
• It have 7 internal channels body position/movement with ambient light , patient marker with acoustic tone. It is piezo tone generator built in programmable. It is data compression mode. It is increased signal to noise ratio.
• It has available module such as respiratory module , BP module , temperature module.


• Sleep study is the test used to diagnose sleep disorders. • IT records brain activity and oxygen level in your blood heart rate and breathing as well as eye and leg moment during the study. • The normal process of falling asleep begins with a sleep stage called Non rapid eye moment sleep. • Sleep apnea or another sleep related breathing disorder: It breathing repeatedly stops and starts during sleep. • Periodic limb movement’s disorders: It involuntarily flex and extend your leg while sleeping. It sometimes associated with restless leg syndrome. • Narcolepsy: It overwhelming daytime drowsiners and sudden attack of sleep in that condition. • REM sleep behavior disorder: This sleep disorder involves acting out dreams as you sleep. • Unusual behavior during sleep: It unusual activities during sleep such as walking moving around lot of rhythmic movements. • Chronic insomnia: It trouble falling asleep or staying asleep. • A sleep lab monitors the following parameters like brain waves, Eye movements, Heart rate, Breathing pattern, Blood oxygen level, Body position, Chest and abdominal movement, Limb movement, Snoring and other noise you make as you asleep.
