Can someone explain sleep hypoxia?

kaayx3 Asked: Can someone explain sleep hypoxia?

Today my doctor told me that he believes I might have sleep hypoxia. Is this the same thing as sleep apnea? If not, can you explain the difference? He wants to do a sleep study to determine if he's correct or not. Can you also explain how the sleep study is conducted and if it IS sleep hypoxia, can you please explain how this is treated? Thanks so much!

It's an oxygen deficiency while you sleep.Sleep apnea is when you stop breathing.Sleep studies vary, but usually occur in a predetermined location with you hooked up to a machine for one to seven nights sleep.They are difficult because they are usually not in your home so you are not as comfortable as you would be creating a different kind of sleep.Good Luck!

Sleep hypoxia is mostly caused by sleep apnea.
There are mostly two types of apnea that may occurs: central or peripheral.

Central apnea is caused by a depression of the respiratory centers and typically occur in people with high obesity (BMI above 35) or in people with chronic bronchitis. Also called obesity-hypoventilation syndrome or Pickwickian Syndrome.

Peripheral apnea is caused by obstruction of the high airways during sleep. This is mostly caused by hypotonicity of the throat muscles during sleep or because of obesity (fat deposits around pharynx).

Peripheral apnea generally causes micro-wake-up during sleep which disturbs normal deep sleep and prevent you from getting enough rest. It also causes high blood tension. People with this type of apnea usually snore.

To better assess your condition, I guess you were prescribed a complete polysomnography or sleep study. Basically, they strap a belt around your waist and stick some electrodes to your scalp. They also put a saturation meter on your finger and a mask on your face. They then let you fall asleep to see if you exhibit some hypoxia events or if you move too much.

To cure sleep apnea of the peripheral type, you can be prescribed a CIPAP. Basically, it is a little machine that help maintain your airways open during sleep so you don't snore or experiment the micro-wake-ups.

Sleep apnea of the central type requires a BIPAP. It is basically a CIPAP which helps you breathe in by forcing air through your airways.

Both these treatments are painless and greatly help people with their symtoms.
You will also be encouraged to lose wight as it usually removes symptoms entirely!

Good luck! ^^
