How do I read my sleep apnea test results?
AHI: What was the overall Apnea/Hypopnea Index (AHI)? The AHI is the measure of how bad the patient’s sleep apnea is….The scale of AHI is:
- < 5 = normal in an adult. (In a child > 1.5 indicates clinically significant sleep apnea)
- 5-15 = mild.
- 15-30 = moderate.
- > 30 = severe.
What do the numbers mean in a sleep apnea test?
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.
What is a good sleep score by age?
Preschool, 3 to 5 years need 10 to 13 hours of sleep including naps. Children, 6 to 12 years need 9 to 12 hours of sleep. Teens, 13 to 18 years need 8 to 10 hours of sleep. Adults between 18 to 61 need seven or more hours of sleep.
How many awakenings per night is normal?
Waking up in the middle of the night is normal. Most of us experience mini-awakenings without even noticing them—up to 20 times per hour. When it comes to observable wake-ups, most people have about two or three per night.
What should your oxygen level be?
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.
What is the highest AHI score?
The Apnoea–Hypopnea Index (AHI) is used to classify the severity of the illness: mild AHI 5 to <15; moderate 15 to <30; and severe 30 or more [5]. It is well known that patients with severe OSA have higher morbidity and mortality rates compared to those with mild or moderate levels [6,7].
How many times should I wake up at night?
Most of us wake up three to four times during the night for varied reasons, and this is considered a part of a normal sleep pattern. However, a lot of us wake more frequently, sometimes even every two to three hours in the night.
What does a healthy sleep cycle look like?
An average sleep cycle lasts about 90 minutes. Ideally, you need four to six cycles of sleep every 24 hours to feel fresh and rested. Each cycle contains four individual stages: three that form non-rapid eye movement (NREM) sleep and one rapid eye movement (REM) sleep.
Why do I wake up at 3am every night?
If you wake up at 3 a.m. or another time and can’t fall right back asleep, it may be for several reasons. These include lighter sleep cycles, stress, or underlying health conditions. Your 3 a.m. awakenings may occur infrequently and be nothing serious, but regular nights like this could be a sign of insomnia.
What should your oxygen level be when you wake up?
If your waking oxygen saturation is greater than about 94 percent on room air, it is unlikely that your saturation during sleep will fall below 88 percent. However, your doctor can order an overnight oximetry test if there is a question about your oxygen saturation levels while you are sleeping.
