A level 2 sleep study (also called Polysomnography) can also be completed from your own home, (but some level 2 sleep studies are offered in a sleep lab or hospital).

In addition to monitoring your breathing activity, oxygen levels, and heart rate, a level 2 sleep study monitors brain and muscle activity..

What is a normal sleep study result?

An index of 5 to 14 indicates a mild level of breathing–and sleep–disturbance. From 15 to 30 is moderate; greater than 30 is severe. The associated drops in blood oxygen levels, known as desaturations, are also measured and categorized. Normal saturation is around 95 percent.

Can you watch TV during a sleep study?

“Once the patient is in bed, ready for sleep, the wires usually do not interfere with sleep,” says Kline. They can read, relax or even watch television before going to sleep since many sleep centers have TVs in the room.

How accurate is a sleep apnea test?

A home test only measures breathing, not actual sleep, so results can be inconclusive or falsely negative. Patients with OSA often breathe through their mouths, which may lead to inaccurate signals. Although rare, a self-administered device may become loose on the finger at night, too.

Can I go to the bathroom during a sleep study?

Although you are not expected to go to sleep at a specific time, you will be encouraged to fall asleep as soon as possible to maximize the amount of sleep time during which you can be observed. Patients needing to use the bathroom during the study need only to notify the technologist.

What is a Type 3 sleep study?

A Type III sleep testing device monitors a minimum of four channels that must include one or more channels of respiratory effort, airflow, oxygen saturation, and heart rate/ ECG.

How many apneas per hour is severe?

It can be mild, moderate, or severe, depending on the number of times in an hour that your breathing stops (apnea) or becomes very shallow (hypopnea). Apnea episodes may occur from 5 to 100 times an hour. More than five apneas per hour is abnormal. More than 30-40 per hour is considered severe sleep apnea.

What is a good sleep apnea score?

Apnea Hypopnea Index (AHI) Based on the AHI, the severity of OSA is classified as follows: None/Minimal: AHI < 5 per hour. Mild: AHI ≥ 5, but < 15 per hour. Moderate: AHI ≥ 15, but < 30 per hour.

What is a normal sleep apnea score?

From the AHI rating chart here, we see that an index less that 5 is considered normal. For an Apnea-Hypopnea Index (or AHI) from 5 to 15 denotes mild sleep apnea. Fifteen to 30 is moderate, while a greater than 30 AHI is considered severe.

What is a good sleep efficiency score?

Normal sleep efficiency is considered to be 80% or greater. For example, if a person spends 8 hours in bed (from 10 p.m. to 6 a.m), at least 6.4 hours or more should be spent sleeping to achieve an 80% or greater sleep efficiency. Most healthy and young adults have sleep efficiencies above 90%.

Why do I need a second sleep study?

The most common indication for a second sleep study is to initiate and optimize positive airway pressure treatment to remedy sleep apnea. It sometimes proves impossible to find the most effective pressure settings either as part of an initial study or with a trial of therapy at home.

What are the different levels of sleep apnea?

Obstructive sleep apnea is classified by severity:Severe obstructive sleep apnea means that your AHI is greater than 30 (more than 30 episodes per hour)Moderate obstructive sleep apnea means that your AHI is between 15 and 30.Mild obstructive sleep apnea means that your AHI is between 5 and 15.

Does sleep apnea go away if you lose weight?

If overweight and obese people lose weight, it would make both sleep apnea and other health problems [such as heart disease] go away. Losing just 10% of body weight can have a big effect on sleep apnea symptoms. In some cases, losing a significant amount of weight can even cure the condition.
