Sleep Apnea

Sleep apnea is more than just loud snoring — it’s a serious condition that affects your breathing and overall health. Learn how PAP IQ helps you understand, manage, and overcome sleep apnea for a better night’s rest.

What Is Sleep Apnea?

Understanding the Disorder That Disrupts Rest and Health

Nearly 30 million adults in the United States alone are afflicted with sleep apnea.  Unfortunately, even after diagnosis and receiving a CPAP device, many people find the therapy difficult to acclimate to until now.

Untreated, sleep apnea puts a strain on your heart by repeatedly causing oxygen levels to drop and blood pressure to surge as you sleep.  It can leave you waking in the morning feeling tired, even after a full night’s sleep.

Types of Sleep Apnea

Understanding the Different Forms of This Common Sleep Disorder

Sleep apnea isn’t one-size-fits-all — it comes in three main types, each with distinct causes and characteristics. Learning the difference between obstructive, central, and mixed sleep apnea is the first step toward proper diagnosis and effective treatment.

Obstructive Sleep Apnea

This is the most common type of Sleep Apnea event. It is caused by relaxation or collapsing of the tissue in your upper airway at the end of exhalation.

There are two types of Obstructive Apnea:

Obstructive

This is a 90% or greater reduction in your normal airflow

Hypopnea

This is a 30% to 90% reduction in your normal airflow

Both types of Obstructive Sleep Apnea are breathing or respiratory events that last for 10 seconds or longer. These events terminate in most cases with an arousal or a slight waking from your sleep and or an oxygen desaturation.

This cycle can repeat hundreds of times in one night and typically are not remembered in the morning.

Central Sleep Apnea

Central Sleep Apnea is a result of the brain not sending the right signals to the diaphragm muscles that control natural breathing.  Central Sleep Apnea can also be the result of other health conditions such as heart failure or stroke.

Central sleep apnea is less common than obstructive sleep apnea.

Mixed Sleep Apnea

As the name implies, it is a combination of both Obstructive and Central Sleep Apnea.

Mixed apnea is defined as a central event that persisted for more than 10 seconds in the beginning, with an obstructive subsequent event type and the duration of the central part less than 80% of the whole event.

Health Implications of Sleep Apnea

Understanding the Risks to Protect Your Health

Untreated sleep apnea can affect more than just your sleep — it can impact your entire body. From heart complications to mental health struggles, recognizing these risks is key to taking your treatment seriously and improving your overall well-being.

Coronary Artery Disease

Sleep apnea reduces oxygen levels during sleep, causing stress on the cardiovascular system. Over time, this increases the risk of plaque buildup in arteries, leading to coronary artery disease and poor heart function.

Congestive Heart Failure

Interrupted breathing patterns force the heart to work harder. This constant strain can weaken the heart muscle, contributing to or worsening congestive heart failure.

Atrial Fibrillation

The oxygen drops and blood pressure spikes during apnea episodes can trigger irregular heart rhythms, such as atrial fibrillation, increasing the risk of stroke and other complications.

Hypertension / High Blood Pressure

Repeated oxygen drops during sleep cause the body to release stress hormones that constrict blood vessels, leading to persistent high blood pressure.

Heart Attack

Sleep apnea places continuous stress on the heart due to oxygen deprivation and elevated blood pressure. These conditions significantly raise the risk of experiencing a heart attack.

Stroke

Reduced oxygen flow and high blood pressure from untreated sleep apnea increase the risk of blood clots and stroke, often without obvious symptoms until a serious event occurs.

Diabetes Type II

Sleep apnea affects glucose metabolism and insulin sensitivity. Poor sleep quality disrupts the body’s ability to manage blood sugar, increasing the risk of Type II diabetes.

Daytime Fatigue

Frequent sleep interruptions prevent deep, restorative rest. This leads to persistent tiredness, sluggishness, and difficulty staying alert during the day.

Morbid Obesity

Sleep apnea and obesity often reinforce each other. Weight gain can worsen airway obstruction, while poor sleep disrupts metabolism and appetite control, promoting further weight gain.

Depression / Anxiety

Chronic sleep deprivation from apnea affects brain chemistry and emotional balance. Many patients experience mood swings, anxiety, or depression as a result.

Memory Loss

Poor oxygenation and fragmented sleep interfere with brain function. This can cause short-term memory lapses and difficulty retaining new information.

Lack of Concentration

Without quality sleep, focus and cognitive performance decline. Individuals may find it harder to stay attentive or complete complex tasks efficiently.

Work, Home, and Automobile Accidents

Daytime drowsiness and reduced alertness from sleep apnea increase the risk of accidents in daily life — whether on the road, at home, or in the workplace.

Fortunately, many of the damaging effects of OSA can be stopped, and even reversed, through diagnosis and treatment.
