Introduction
Confused between a CPAP machine and an oxygen concentrator?
Both help with breathing, but they serve different purposes. If you or a loved one has been diagnosed with sleep apnea, COPD, or other breathing conditions, this guide breaks down the differences so you can make an informed decision.
1. What Is a CPAP Machine?
A CPAP (Continuous Positive Airway Pressure) machine keeps your airway open while you sleep. It pushes a constant flow of air into your nose or mouth to prevent breathing pauses caused by obstructive sleep apnea (OSA).
Best for:
Sleep apnea
Loud snoring
Daytime fatigue from poor sleep
2. What Is an Oxygen Concentrator?
An oxygen concentrator is a device that delivers purified oxygen to those with low blood oxygen levels. It takes in air, removes nitrogen, and supplies oxygen-rich air through a tube or nasal cannula.
Best for:
COPD (Chronic Obstructive Pulmonary Disease)
Lung conditions
Post-COVID recovery
3. Key Differences Between CPAP and Oxygen Concentrator
Feature | CPAP Machine | Oxygen Concentrator |
Purpose | Keeps airway open during sleep | Provides concentrated oxygen |
Main Use | Sleep apnea (OSA) | COPD, lung disease, low oxygen levels |
Air Flow | Pressurised room air | Enriched oxygen delivery |
Usage Time | Typically during sleep | Can be used day or night |
Prescription Needed | Yes | Yes |
Portability | Available in travel versions | Also available in portable versions |
4. When to Use CPAP vs Oxygen Therapy
Use CPAP if you:
Have sleep apnea or loud snoring
Need help keeping your airway open at night
Use oxygen concentrator if you:
Have low SpO2 levels (usually under 90%)
Struggle with lung disease or chronic bronchitis
Feel breathless even while resting
Some people with overlap syndrome (COPD + OSA) may need both.
5. Can You Use Both Together?
Yes, in some cases.
For patients with both sleep apnea and oxygen deficiency, CPAP machines can be fitted with oxygen inlets to deliver positive airway pressure plus oxygen.
This is common in:
Severe OSA with desaturation
Advanced COPD
Post-surgical recovery or elderly care
Always consult a respiratory specialist before combining both.
Availability in Malaysia
Both devices are widely available in:
Kuala Lumpur & Selangor: Subang Jaya, Bangsar, Shah Alam
Johor, Melaka & Negeri Sembilan: Johor Bahru, Seremban, Ayer Keroh
Perak & Pulau Pinang: Ipoh, Taiping, George Town
Most suppliers offer:
Purchase or rental options
After-sales support & maintenance
Conclusion
While CPAP and oxygen concentrators both support breathing, they serve different roles. CPAP treats sleep apnea by maintaining airflow, while oxygen concentrators treat low blood oxygen caused by lung issues.
Your doctor will help you choose the right device based on your condition. Always get tested and diagnosed before starting any therapy.
FAQs
1. Can I use CPAP if I don’t have sleep apnea?
No, it’s designed specifically for OSA. Using it unnecessarily can cause harm.
2. Is oxygen therapy addictive?
No. It supports oxygen levels but should only be used as prescribed.
3. Can I rent these devices in Malaysia?
Yes. Many clinics and online stores offer short- and long-term rental plans.
4. What’s the price range in Malaysia?
CPAP: RM2,500–RM5,000
Oxygen concentrator: RM3,000–RM6,000
5. Are portable versions available?
Yes, both CPAP and oxygen concentrators come in travel-friendly models.
