Recommended oxygen level during sleep
Doctors can utilize the very best pulse oximeter for sleep apnea to find out the degree of oxygen in the human body in percent form. This measurement is referred to as the SpO2 (or, the oxygen equilibrium level). The standard oxygen saturation level within the entire body is between 95% and 100 percent.
Sleep apnea is considered a life-threatening sleep disorder as it reduces oxygen levels and causes disturbed sleep. Oxygen deprivation and lack of sleep can lead to heart diseases and memory problems and it is advisable to consult a doctor if you experience any of its symptoms.
Health experts suggest that one way to find out if you are suffering from sleep apnea is to use an oximeter. It is a device that measures oxygen levels in your blood and is often used in hospitals. But there are also pulse oximeters that you can use at home.
What are the uses of a pulse oximeter?
Have you ever been in a hospital where the patient you visited had a small clamp-like instrument attached to his or her finger or earlobe? If yes, chances are high that you have already seen a pulse oximeter. The purpose of this device is to determine whether the heart is doing good in distributing oxygen in the entire body.
Aside from its main function, a pulse oximeter can also be used to assess a lung medication, the performance of a ventilator, how much a person can withstand strenuous physical activity, or know if a person experiences a sudden pause in breathing.
How does a pulse oximeter work?
The probe or the clamp-like part of the oximeter should be clipped on a finger, toe, or earlobe where it can fit perfectly. It will release small beams of light that can pass through the blood in the body part where it is attached and send information to a monitor. This is usually painless and only a small amount of pressure can be felt.
It should be not too tight on the finger as it can constrict blood flow and not to lose as it can let other kinds of light to go in. Also, nail varnish, pigment on finger, and patient movement could interfere with the performance of the probe.
What is the normal oxygen level during sleep?
A person’s oxygen level normally reads from 90-100% during sleep and can be considered abnormal when it falls down below 88%. The common symptoms of oxygen deprivation during sleep are:
- Restlessness
- Rapid breathing
- Rapid heart rate
- Waking up with a headache
- Bluish tint to nail beds, earlobes, and/or lips
- High blood pressure
- Shortness of breath
- Waking up coughing or choking
- Snoring
- Lack of concentration during daytime
- Weakness or lack of energy
- Drowsiness
- Poor memory
When this happens, you should immediately seek professional help to avoid further medical problems.
