What Is a CPAP Machine and Who Is It For?
Maybe your doctor has recommended a CPAP machine for you or a family member, or you’re researching sleep apnea on your own — either way, the first question is a natural one: what exactly is a CPAP machine, and who is it for?
This guide explains how CPAP works, its connection to sleep apnea, why the mask and humidifier matter, how to maintain the machine, and what it typically costs in Bangladesh along with rental options in Dhaka. The goal is to give you a solid, informed understanding — not a diagnosis or personal treatment recommendation.
1. What Is CPAP?
CPAP stands for Continuous Positive Airway Pressure. A CPAP machine delivers continuous positive-pressure air through a mask during sleep, which helps keep an obstructed upper airway open. The NHS also describes CPAP as a device that delivers air pressure through a mask during sleep.
2. How Does a CPAP Machine Work?
In simple terms:
CPAP Machine → Tubing → Mask → Airway
- The machine generates a specific air pressure
- That air travels through tubing to the mask
- The patient breathes in this pressurized air through the mask
- This positive pressure helps prevent the airway from collapsing
Important: CPAP does not supply oxygen the way an oxygen cylinder does. CPAP works primarily by using pressurized (regular) air to keep the airway open — this is a fundamentally different function.
3. Who Is CPAP Used For?
The most common educational use case for CPAP is Obstructive Sleep Apnea (OSA) — a condition where the upper airway repeatedly narrows or closes during sleep, causing breathing to be interrupted again and again.
According to the NHS, CPAP helps prevent the airway from becoming too narrow in sleep apnoea.
Important: loud snoring alone doesn’t mean CPAP is needed. Snoring can be associated with sleep apnea, but snoring by itself doesn’t establish that CPAP is required — whether CPAP is actually needed is determined through a sleep study and a doctor’s evaluation.
What Is Sleep Apnea?
Obstructive Sleep Apnea is a condition where the throat muscles relax during sleep, causing the upper airway to narrow or briefly close, which repeatedly interrupts or reduces breathing. These interruptions can lower sleep quality and cause daytime fatigue. A proper diagnosis is generally made through a sleep study.
CPAP vs Auto CPAP vs BiPAP
Fixed-Pressure CPAP: delivers one steady pressure throughout the night.
Auto CPAP / APAP: automatically adjusts pressure within a clinician-set range, adapting to the patient’s breathing pattern.
BiPAP: a different device from CPAP, providing two separate pressure levels for inhale and exhale. BiPAP is generally used in specific situations, but this article doesn’t provide detailed medical recommendations on BiPAP’s indications — which device is appropriate should be determined by a clinician’s evaluation.
CPAP Mask
The right mask is essential for CPAP to work effectively. There are three main types:
- Nasal Mask — covers only the nose area
- Full Face Mask — covers both the nose and mouth
- Nasal Pillow Mask — uses a minimal-contact interface near the nostrils
Important points:
- Proper mask fit is essential
- Air leakage can affect both comfort and therapy effectiveness
- Mask size/shape can vary from person to person
- A shared (previously used by someone else) mask should not be used
Humidifier
What is a humidifier chamber? It’s a water container attached to the CPAP machine, through which air passes and picks up a little moisture.
Why is it used? For some users, it can help reduce discomfort like nasal or throat dryness.
Important points:
- Having a humidifier makes regular cleaning even more important
- Always follow the manufacturer’s recommended water and cleaning instructions
Medical Product BD’s rental packages may include a humidifier chamber depending on the model/package.
Maintenance: How to Care for a CPAP Machine
Regular Cleaning:
- Clean the mask cushion regularly
- Clean the tubing
- Clean the humidifier chamber
- Keep the machine’s exterior clean
According to NHS guidance, regularly cleaning the mask cushion and maintaining a weekly cleaning routine for the mask, straps, and tubing is important.
Filter:
- Follow the manufacturer’s instructions for your specific model
- Replace a dirty or damaged filter promptly
Inspection:
- Check tubing for cracks or leaks
- Check the mask for damage
- Check the condition of the water chamber
- Check the power cable/adapter
Does CPAP Work Without Electricity?
A CPAP machine requires electricity to maintain continuous positive pressure throughout the night. Given load-shedding conditions in parts of Bangladesh, anyone who needs CPAP every night may want to consider backup power (like an IPS), particularly for models that aren’t battery/DC compatible. Check the specific model’s power requirements to confirm.
Buy vs Rent: Which Fits Your Situation?
For those who need CPAP only temporarily — for example, during a trial period recommended after a sleep study — rental can be a practical option. For long-term regular use, buying can become more cost-effective over time. The right choice depends on your expected duration of use and budget.

Frequently Asked Questions
1. What is a CPAP machine? CPAP stands for Continuous Positive Airway Pressure — a device that delivers continuous pressure air through a mask during sleep, helping keep the airway open.
2. How does a CPAP machine work? It creates air pressure that travels through tubing to a mask, which the patient breathes through; this positive pressure helps prevent the airway from collapsing during sleep.
3. Who is a CPAP machine used for? Primarily patients with Obstructive Sleep Apnea (OSA), whose doctor has recommended CPAP therapy based on a sleep study.
4. Does snoring alone mean I need a CPAP machine? Not necessarily. Snoring can be associated with sleep apnea, but snoring alone doesn’t establish that CPAP is needed — a proper medical evaluation or sleep study is required.
5. What is the difference between CPAP and Auto CPAP? Fixed CPAP delivers one steady pressure all night, while Auto CPAP automatically adjusts pressure within a clinician-set range.
