Sleep Apnea: Understanding Blood Oxygen Levels

What is Blood Oxygen Level?

Blood oxygen levels, also known as arterial oxygen saturation or SpO2, refer to the amount of oxygen present in a person’s bloodstream. This level is usually measured by using a pulse oximeter, which is a device that sends light through the skin and measures how much of it is absorbed. Normal blood oxygen levels can range from 95-100%, and anything below 90% may indicate an underlying health issue such as sleep apnea. Low blood oxygen levels can be caused by various factors including smoking, heart disease, lung diseases like COPD or asthma, and air pollution. It is important for people with low blood oxygen levels to seek medical attention in order to identify any potential causes and receive appropriate treatment.

Sleep apnea is one of the most common causes of low blood oxygen levels. Sleep apnea occurs when a person’s breathing stops during sleep due to obstruction in their airway or other issues with their respiratory system. If left untreated over time this can lead to serious complications such as high blood pressure, stroke or even death due to lack of adequate airflow into the lungs while sleeping. Common symptoms include loud snoring at night, excessive daytime sleepiness and fatigue during waking hours despite getting enough rest at night. Diagnosing sleep apnea requires an overnight test where patients are monitored for changes in their breathing patterns while they are asleep which can then be used to determine if there are any obstructions causing them difficulty breathing properly at night time.

In order to treat sleep apnea effectively doctors will often recommend lifestyle changes such as weight loss if needed along with CPAP (Continuous Positive Air Pressure) therapy which involves wearing a mask connected via tubing to a machine that provides pressurized air throughout the night while sleeping so that your airways remain open allowing you better access breath more easily without interruption from obstructions in your throat area . Other treatments may include surgery depending on what type of blockage is causing problems with your breathing patterns during sleep time periods .
