This can be caused by extra tissue in the back of the airway such as inflamed tissue to enlarged tonsils or adenoids. The tongue can fall back into the airway and help block it. Also a decrease in the tone of the upper airway muscles that help hold the airway open can cause sleep apnea.

The most common cause of airway obstruction in an unconscious patient lying on his back is due to the relaxed tongue falling back to obstruct the airway. Head tilt and chin lift are paramount procedures to provide a clear airway in mouth-to mouth resuscitation. See similar questions...

There are three known treatments for sleep apnea: surgery, oral appliances and PAP treatment. PAP treatment has proven to be the most effective in adults. For children, surgery is the obvious solution. See similar questions...

Your body is paralyzed during REM, your body can't even stand (This is why sleep walking happens in other stages of sleep). Sometimes the body fails to turn on your muscles immediately after REM. Normally this condition lasts only a few seconds, but sometimes can it go on for minutes, which causes a very scary feeling. But just remain calm, it will pass. And it is not at all dangerous. You should also know that sleep paralysis is great for leaving your body. See similar questions...

Efforts to understand sleep patterns and habits in SMS individuals have led to the confirmation of an unusual inverted circadian rhythm of melatonin. Research to determine the underlying cause for this disrupted sleep cycle has only just begun. Therapeutic management of the sleep disorder in SMS remains a challenge for physicians and parents. Reports of therapeutic benefit from melatonin suggest general improvement of sleep without major adverse reactions. See similar questions...

She can take it as needed, beginning mid-cycle. Most women find though, that by taking it all month long they feel better in general. See similar questions...

The most common form of this condition is obstructive sleep apnea, which occurs when the tissues of the throat completely obstruct the airway intermittently during the night. Some of the causes include obesity, abnormality of the jaw or throat, and enlarged tonsils and adenoids. See similar questions...

Apnoea is caused by the same muscles that cause snoring. It occurs when the muscles of the soft palate at the base of the tongue and the uvula (the small fleshy piece of tissue hanging back of the throat) relax, partially blocking the opening of the airway. However, sleep apnoea is more dangerous than snoring in that it alters normal breathing patterns. While asleep, suffers may stop breathing for between 10 to 25 seconds at a time, depleting the bloodstream and brain of vital oxygen supplies. See similar questions...

Hotels, ger camps, quaint inns, homestays and camping. On a given trip you may stay in a number of different accommodations. In Mongolia, when ger camps are available we use them, when not we use homestays or vehicle supported camping. In Tibet the camping is quite rugged with several days where we are traveling only with pack horse support. In Uruguay we stay in comfortable hotels and local inns. See similar questions...

Floats collapse for two reasons: 1) over pressure and 2) water hammer. Water hammer generally occurs during blow down. It sounds like snapping and crackling in the pipe. See similar questions...

The exact cause of OSA remains unclear. Generally, sleep apnea happens when enough air cannot move into your lungs while you are sleeping. When you are awake, and normally during sleep, your throat muscles keep your throat open so that air can flow into your lungs. However, with obstructive sleep apnea, the throat briefly collapses, causing pauses in your breathing. With pauses in breathing, your oxygen level in your blood may drop. See similar questions...

Follow CDC protocols for disease control, and manikin instructions for maintaining best protection. Airways must be replaced according to instructions to remove any chance of bacteria growth and contamination. Use household cleaners like soap and water, 409, Fantastic, or others to remove dirt and grime from the manikins. Laerdal adapters function only with Heart Stream models. Heart Start models will not work. See similar questions...

Your arches are your body's suspension. They are supposed to flex. That is how they help your feet absorb the shock of impact. If your arches collapse to the ground (flexible flat feet), it is like driving your car with broken springs, and if the arches don't move (rigid) it would be like a car with blocked suspension or no suspension at all. Rigid orthotics are often a painful ride that can take months to become used to. See similar questions...

VoIP allows you to make telephone calls using a computer network, over a data network like the Internet. VoIP converts the voice signal from your telephone into a digital signal that travels over the internet then converts it back at the other end so you can speak to anyone with a regular phone number. When placing a VoIP call using a phone with an adapter, you'll hear a dial tone and dial just as you always have. See similar questions...

Both spin-on hydraulic filters and cartridge hydraulic filters have a collapse rating. The collapse rating is a rating of the filter's ability to resist collapse. Collapse ratings are given in PSID (differential pressure). Differential pressure is the difference in pressure from the inlet of the filter to the outlet of the filter. See similar questions...
