Obstructive Sleep Apnea (OSA) is a common and clinically significant sleep disordered breathing in which the upper airway becomes blocked repeatedly while sleeping. These episodes can make it hard to sleep normally, which lowers the amount of oxygen in the blood and raises the risk of heart disease (i.e. coronary artery disease and congestive heart failure). OSA is often misdiagnosed and not treated enough, but early detection and the right care can make a big difference in the quality of life of those with it.
This article is meant to give you a general overview of how OSA is diagnosed and treated. Its goal is to give doctors the knowledge and tools they need to diagnose and treat this disorder correctly. By the end of this guide, medical professionals will have a clear idea of what causes OSA, how to diagnose it, and how to treat it.
What is Obstructive Sleep Apnea (OSA)?
Obstructive Sleep Apnea (OSA) is a sleep disorder in which the upper airway is blocked partially or entirely repeatedly while sleeping. This blockage can make the person snore loudly, gasp for air, or wake up late at night. Less airflow can lower the amount of oxygen in the blood, which can significantly affect health and quality of life.
Explain the Symptoms of OSA
The signs can be different for each person, but here are some of the most common ones:
- Snoring: This is often the most obvious sign of OSA, and it can be loud and bother other people.
- Gasping or choking during sleep: As the person’s airway gets blocked, they may find it hard to breathe and make choking or gasping sounds.
- Excessive daytime sleepiness: People with OSA may feel too tired during the day because they don’t get enough rest at night.
- Having trouble staying asleep: Repeated partial or complete blockages of the airway can cause the person to wake up several times during the night.
- Morning headaches: If the brain doesn’t get enough oxygen while you sleep, you might wake up with a headache.
- Trouble staying awake or paying attention during the day: OSA can cause memory loss and make it hard to concentrate during the day.
These are some of the most common signs of OSA. However, not everyone with OSA will have all of these signs, and some people may have other signs that aren’t listed here. If you think you might have OSA, it’s important to talk to a doctor or nurse.
The Causes of OSA
Obstructive Sleep Apnea (OSA) has many possible causes, which can be put into two main groups: anatomical and neurological.
Anatomical causes:
- Obesity: Extra weight, especially around the neck, can make OSA more likely because it can make the airway narrow.
- Enlarged tonsils or adenoids: It can make it hard to breathe, especially for kids.
- Narrow airway: Some people are born with a narrow airway, which can make them more likely to have OSA.
Neurological causes
- Neurological disorders: Parkinson’s disease, amyotrophic lateral sclerosis (ALS), and stroke are all neurological conditions that can cause muscle weakness, which can lead to OSA.
- Medications: Drugs like sedatives, hypnotics, and opioids can cause muscles to relax and block the airway.
- Alcohol and drug use: Alcohol and some drugs can cause muscles to relax, which can make OSA more likely.
It’s important to remember that OSA can be caused by a combination of things, and that often a number of anatomical and neurological problems can lead to the disorder. OSA can happen to people of all ages and is not limited to any one group or demographic.
The Diagnosis of OSA
Diagnoses of Obstructive Sleep Apnea (OSA) usually include a physical exam, a sleep study (polysomnography), and a home sleep apnea test.
Physical examination
A doctor or nurse will do a physical exam to look for signs of OSA, like a big tongue or tonsils or a narrowed airway. They will also ask about signs like snoring, feeling tired during the day, and having trouble staying asleep.
A sleep study (polysomnography)
While sleeping, the brain, eyes, muscles, heart rate, and breathing are monitored in a sleep lab. This test might reveal how often and severe your sleep apneas and hypopneas are.
Home sleep apnea test
A home sleep apnea test is a simpler version of a sleep study that can be done at home. The person wears a portable device that measures their oxygen levels, heart rate, and breathing while they sleep. This test can tell if obstructive sleep apnea is present and can be used to figure out the right treatment.
OSA will be diagnosed based on the results of the physical examination, sleep study, and home sleep apnea test. They will also suggest the best way to treat the condition. It’s important to remember that only a sleep specialist or a pulmonologist can diagnose OSA for sure.

What Are The Treatment Options?
Treatment options for Obstructive Sleep Apnea depend on the individual’s specific needs and circumstances, but some standard treatment options include:
Lifestyle changes
- Weight loss: Losing weight can help to reduce the risk factors of OSA, especially in cases where obesity is a contributing factor.
- Avoiding alcohol and sedatives: These can relax the airway muscles and worsen OSA symptoms.
- Sleeping on your side: Sleeping on your back can cause the tongue and soft palate to collapse to the back of the throat and block the airway. Sleeping on your side can help prevent this.
Medical treatment
- Continuous positive airway pressure (CPAP): This is a common treatment for OSA. It involves using a machine that delivers air pressure through a CPAP mask that the individual wears while sleeping. The air pressure helps to keep the airway open, reducing the number of apneas and hypopneas during sleep.
- Oral appliances: These are devices worn in the mouth and help keep the airway open by repositioning the jaw and tongue.
- Surgery: In some cases, surgery may be recommended to remove excess tissue from the airway, such as the tonsils, or to repair structural abnormalities that are blocking the airway.
It is essential to note that the optimal OSA treatment depends on the individual’s unique demands and circumstances. Some people may only require lifestyle changes, while others may need a combination of lifestyle changes and medical treatment. In some cases, surgery may be the best option. A healthcare provider will be able to recommend the most appropriate treatment plan.
How Does a CPAP Machine Treat OSA?
A Continuous Positive Airway Pressure (CPAP) machine is a common treatment for Obstructive Sleep Apnea (OSA). The machine delivers a steady stream of pressurized air through a mask that the individual wears while sleeping. The air pressure keeps the airway open, minimizing apneas and hypopneas during sleep.
When the individual breathes in, the air pressure is delivered through the mask and into the airway. This pressure helps to keep the airway open, preventing it from collapsing and blocking the flow of air. As a result, the individual is able to breathe more easily and sleep more soundly.
CPAP therapy typically requires a mask covering the nose, nose, and mouth. The mask is connected to the CPAP machine via a tube. During a sleep study, the CPAP machine will be set to a specific pressure determined by a sleep specialist or pulmonologist. The pressure is usually between 4 and 20 cm H2O.
CPAP therapy is generally well-tolerated and effective in treating OSA. However, some people may find the mask uncomfortable or claustrophobic and have trouble getting used to the therapy. In this case, a healthcare provider may recommend alternative treatments such as oral appliances or surgery.
Conclusion
In this article, we’ve talked about the most common signs, like snoring, gasping or choking while sleeping, being tired during the day, having trouble staying asleep, getting headaches in the morning, and having trouble paying attention or staying awake. We also discussed the possible causes of OSA, which can be put into two main groups: anatomical and neurological.
If you or someone you know might have OSA, you must talk to a doctor. They will be able to give you a correct diagnosis and suggest a suitable treatment plan to help you deal with the symptoms and lower the risks of OSA. Don’t let OSA change the way you live.
