Non-invasive ventilation is also called continuous positive airway pressure (CPAP) therapy.

About CPAP

• A CPAP device delivers air to your lungs with a slight positive pressure as you inhale and exhale.
• This lets you breathe more air without having to work harder.
• The constant pressure of this therapy helps to keep your airways open and prevents them from collapsing at night, causing sleep apnea.

What You Need to Know

• It's important that your CPAP mask fit properly.
• For CPAP therapy to work, you must use the device.
• The most common complication of non-invasive ventilation is an abrasion on your nose. Applying a wound-care dressing can eliminate this problem.
