Do I need a prescription for a CPAP machine?

This is one of the most common questions asked by people diagnosed with sleep apnea in the United States. CPAP and BiPAP machines are regulated medical devices, and understanding prescription requirements is essential for safe, effective, and legally compliant treatment.

What Is a CPAP Machine?

A CPAP (Continuous Positive Airway Pressure) machine is used to treat obstructive sleep apnea (OSA). It delivers a steady flow of air to keep your airway open while you sleep.

Benefits of CPAP Therapy

• Reduces breathing interruptions

• Improves oxygen levels

• Decreases snoring

• Enhances sleep quality and daytime alertness

CPAP is the most commonly prescribed treatment for sleep apnea.

What Is a BiPAP Machine?

A BiPAP (Bi-level Positive Airway Pressure) machine provides two pressure levels:

• Higher pressure when inhaling (IPAP)

• Lower pressure when exhaling (EPAP)

Who Typically Needs a BiPAP?

• Severe sleep apnea patients

• Central sleep apnea

• COPD or respiratory disorders

• Patients who struggle with CPAP pressure

BiPAP therapy is more advanced and requires precise medical supervision.

Why Using a Machine Without a Prescription Is Risky

Using CPAP or BiPAP without medical guidance can:

• Cause discomfort or breathing issues

• Reduce therapy effectiveness

• Lead to improper pressure settings

Sleep apnea should always be treated under professional supervision.
