CPAP Machine Uses – What a CPAP Is Used For
A CPAP machine (Continuous Positive Airway Pressure) is a medical device that delivers a steady stream of air through a mask to keep the airway open during sleep. It is mainly used to treat sleep-related breathing disorders.
Main Uses of a CPAP Machine
1. Obstructive Sleep Apnea (OSA)
This is the primary and most common use of a CPAP machine.
- Prevents airway collapse during sleep
- Stops loud snoring caused by blocked airways
- Reduces pauses in breathing (apnea episodes)
- Improves sleep quality and daytime alertness
2. Central Sleep Apnea (Selected Cases)
In some patients with central sleep apnea (where the brain fails to signal breathing properly), CPAP may be used depending on severity and medical advice.
3. Reducing Snoring (When Medically Indicated)
For people whose snoring is due to airway obstruction, CPAP can significantly reduce or stop snoring.
4. Improving Oxygen Levels During Sleep
CPAP helps maintain:
- Stable oxygen levels
- Better nighttime breathing
This is especially important for people with sleep-related oxygen drops.
5. Supporting Heart and Metabolic Health
By treating sleep apnea, CPAP can help reduce risks associated with:
- High blood pressure
- Heart disease
- Stroke
- Poor blood sugar control
How a CPAP Machine Works
- Draws room air
- Pressurises it to a constant level
- Delivers air through a mask (nasal, nasal pillows, or full-face)
- Keeps the airway open all night
Common CPAP Mask Types
- Nasal mask – covers the nose
- Nasal pillows – sit inside the nostrils
- Full-face mask – covers nose and mouth
Summary of CPAP Machine Uses
- Treats obstructive sleep apnea
- Reduces breathing interruptions during sleep
- Improves oxygen flow at night
- Reduces snoring caused by airway blockage
- Improves sleep quality and daytime energy
- Lowers long-term health risks linked to sleep apnea
