Sleep apnea will be divided into 3 different levels based on the AHI index, based on the number of times breathing is reduced and stopped. The mildest level is mild sleep apnea, which usually only presents mild symptoms that are hardly noticeable. The most severe level is severe sleep apnea, which causes serious disturbances to sleep and overall health. This level is very difficult to treat and requires a combination of multiple methods. Most patients discover moderate sleep apnea when the symptoms become more apparent and start to affect their daily lives. In this article, CLM Sleep will provide more detailed information about moderate sleep apnea, including symptoms, diagnostic methods, and treatment options.
What is moderate sleep apnea?
Moderate sleep apnea is a sleep disorder characterized by repeated interruptions in breathing throughout the sleep process, with an AHI sleep apnea index ranging from 15 to 30. It is an index that measures the number of times apnea and hypopnea occur in one hour of sleep. These disruptions will reduce oxygen in the blood, affect sleep quality, and disrupt the sleep-wake biological clock. Leading to feelings of fatigue, daytime sleepiness, and increasing the risk of other health issues.
Moderate sleep apnea is a condition more serious than mild sleep apnea, but not as severe as severe sleep apnea. In mild sleep apnea, breathing disruptions are occasional and less likely to cause major health problems. However, in moderate sleep apnea, breathing interruptions happen more frequently, which increases the risk of health issues, such as heart and blood vessel problems. If left untreated promptly, moderate sleep apnea will progress to a more severe stage known as severe sleep apnea, with more than 30 breathing pauses per hour. This level will make sleep apnea more complicated, difficult to treat, and at high risk of leading to serious health complications.
Symptoms of Moderate Sleep Apnea
There are 3 common levels of sleep apnea: Mild sleep apnea, Moderate Sleep Apnea, and Severe Sleep Apnea. The symptoms of Moderate Sleep Apnea are more pronounced than those of mild sleep apnea, beginning to cause discomfort and affecting daily life. Here are some common symptoms of Moderate Sleep Apnea:
Nighttime Symptoms
Loud and frequent snoring.
Noticeable and repeated episodes of apnea/hypopnea throughout the night.
Possible awakenings due to shortness of breath.
Night sweats.
Frequent position changes during sleep due to discomfort.
Heart palpitations or a racing heartbeat upon waking.
Daytime Symptoms
Increased daytime sleepiness, affecting focus and productivity.
Morning headaches or dry throat upon waking.
Frequent awakenings at night without clear memory of the cause.
Increased irritability and decreased ability to handle stress.
Occasional shortness of breath or a feeling of breathlessness even during the day.
Everyone needs to monitor their sleep regularly to detect any sleep abnormalities early, allowing for timely interventions to protect their health. Monitoring sleep can be done through modern tracking devices such as smartwatches, heart rate monitors, or through sleep studies at medical facilities. When abnormal signs such as loud snoring, sudden waking due to choking, or excessive daytime sleepiness are detected, it is necessary to see a doctor for examination and diagnosis. Early detection not only helps improve the quality of life but also reduces the risk of serious diseases such as cardiovascular issues, diabetes, or stroke.
Diagnosis of Moderate Sleep Apnea
In-lab Sleep Study
An in-lab sleep study, or polysomnography (PSG), is the gold standard for diagnosing moderate sleep apnea. It involves monitoring brain activity, heart rate, oxygen levels, and breathing patterns in a controlled environment. This comprehensive test provides detailed insights into the severity of the condition.
Home Sleep Study
A home sleep study (HSAT) is a more convenient option, where patients use a portable device to measure breathing, oxygen levels, and heart rate while sleeping at home. Although less detailed than an in-lab study, it is effective for diagnosing moderate to severe sleep apnea in many cases.
Treatment Options for Moderate Sleep Apnea
Ngoài việc thay đổi lối sống và rèn luyện những thói quen lành mạnh thì điều trị Moderate Sleep Apnea cũng cần kết hợp với CPAP, các thiết bị hỗ trợ và có thể xem xét phẫu thuật. Dưới đây là các phương pháp điều trị phổ biến:
In addition to changing lifestyle and cultivating healthy habits, treating Moderate Sleep Apnea also requires the use of CPAP, supportive devices, and possibly considering surgery. Here are the common treatment methods:
CPAP Machine (Continuous Positive Airway Pressure)
The CPAP machine is the main treatment for moderate sleep apnea. It provides a continuous stream of air pressure to keep the airways open throughout the night. The machine is highly effective but requires time to adjust and may take some time to get used to. The patient needs to use the CPAP machine every night for optimal results.
Mandibular Advancement Device (MAD)
MAD (Mandibular Advancement Device) is a mouthpiece worn during sleep that moves the lower jaw and tongue forward to keep the airway open. It is typically used for those with mild to moderate sleep apnea without severe airway obstruction. MAD is an alternative treatment for patients who cannot tolerate or prefer not to use CPAP.
Lifestyle Changes
Weight Loss: Losing weight can help reduce airway obstruction and improve sleep apnea symptoms.
Avoid Alcohol and Sedatives: Alcohol and sedatives relax the muscles, increasing the likelihood of airway collapse, so they should be avoided before bedtime.
Change Sleep Position: Sleeping on the side rather than on the back can reduce the chance of airway obstruction.
Exercise: Regular physical activity can improve overall health and help reduce sleep apnea symptoms.
Surgery
Tonsillectomy or Uvulopalatopharyngoplasty (UPPP): If the sleep apnea is caused by an obstruction in the throat, surgery may be recommended to remove excess tissue or tonsils.
Nasal or Palatal Surgery: If structural issues with the nose or palate cause airway obstruction, surgical procedures to improve airflow through the nose and mouth may be considered.
Jaw Surgery: In some cases, jaw surgery may be recommended to improve the alignment of the jaw and open the airway.
Treatment of Related Health Issues
Treating High Blood Pressure: Sleep apnea can contribute to high blood pressure, so managing hypertension may improve sleep apnea symptoms.
Managing Heart Conditions: If the patient has heart disease or arrhythmias due to sleep apnea, simultaneous treatment of these conditions may be required.
Monitoring and Regular Check-ups
Sleep Specialist Consultation: Regular follow-ups with a sleep specialist are essential to monitor progress, adjust treatment plans, and ensure effective use of CPAP or other devices.
Home Sleep Apnea Testing: Some patients may be asked to undergo home sleep monitoring to assess improvements after treatment.
The Levels of Sleep Apnea
Mild, moderate, and severe sleep apnea are all characterized by interruptions in breathing during sleep, which can lead to a range of symptoms, including snoring, daytime fatigue, and disruptions in sleep quality. Regardless of the severity, all forms of sleep apnea share the common underlying issue of airway obstruction, often caused by the relaxation of throat muscles. In all levels, these interruptions in breathing can negatively affect sleep, overall health, and quality of life. Early detection and proper management are crucial at any stage to prevent further health complications, such as cardiovascular diseases or diabetes.
Differences in Sleep Apnea Severity:
| Aspect | Mild Sleep Apnea | Moderate Sleep Apnea | Severe Sleep Apnea |
| Definition | 5 <= AHI index <= 15 (5 to 15 episodes of apnea or hypopnea per hour of sleep) | 15 <AHI index <= 30 (15 to 30 episodes of apnea or hypopnea per hour of sleep) | 30< AHI index (over 30 episodes of apnea or hypopnea per hour of sleep) |
| Symptoms | – Light or occasional snoring. | – Loud, frequent snoring. | – Very loud snoring with frequent pauses in breathing. |
| – Occasional awakenings due to breathing difficulty. | – Noticeable awakenings, often due to choking or gasping for air. | – Frequent awakenings with choking, gasping, or difficulty breathing. | |
| – Mild daytime fatigue and sleepiness. | – Increased daytime sleepiness, irritability, headaches. | – Extreme daytime fatigue, severe mood swings, difficulty concentrating. | |
| Treatment | – Lifestyle changes (weight loss, sleep position). | – CPAP therapy or MAD (Mandibular Advancement Device). | – CPAP therapy or other more invasive treatments, including surgery. |
| – Oral devices (MAD) for mild cases. | – CPAP is commonly used. | – Surgery may be necessary (e.g., UPPP, jaw surgery). | |
| – Monitoring to ensure no progression of the condition. | – Regular follow-up with a sleep specialist. | – Frequent medical monitoring and treatment adjustments. |
Understanding these levels is crucial in determining the right approach to managing sleep apnea and preventing its progression.
