All About Non-Invasive Ventilation (NIV)

What It Is, What it's For, What It Offers

For people who have difficulty breathing due to such conditions as COPD (chronic obstructive pulmonary disease), non-invasive ventilation (NIV) is a proven effective therapy that has been widely used since the 1980s. For COPD patients who have obstructive sleep apnea components along with COPD, NIV can effectively treat both COPD and OSA when they are present together. This is called overlap syndrome. 

Non-invasive therapy, or NIV, helps you breathe by using positive pressure to help support the work of your respiratory muscles. NIV also allows for the support of breathing without the need for intubation or a tracheotomy. Studies demonstrate that NIV also reduces the risk of infection, decreases hospitalizations, and improves quality of life.  

NIV requires that you wear a mask over your nose, mouth, or both. The mask is connected to a device that delivers pressurized air set to treat your specific condition(s). Positive pressure enables you to use oxygen more effectively within your body. NIV also reduces the carbon dioxide in your bloodstream, which can cause shortness of breath, especially in people with respiratory problems. 

Lesley Williams, Apria’s Market Clinical Trainer, and a registered respiratory therapist, says, “NIV can be customized to your specific requirements, whether you need breathing support during the day, night, or both. It’s suitable for people at home or in a hospital setting. It’s also portable.”

Masks available for NIV Therapy

To deliver the needed therapy, a mask is required. And, you have options:

  • Full face masks cover both your mouth and nose
  • Nasal masks fit over your nose
  • Nasal pillows have prongs that fit in the nose. Nasal pillows are even lighter and smaller than nasal masks

To help ensure your NIV therapy is a success, it’s important to choose the most appropriate mask Your doctor and respiratory therapist can help you find the mask that best suits your needs and fits properly. Your respiratory therapist will also show you how to put on your mask so that it rests snugly on your face.

Other factors determining NIV Success

Anytime you begin a new therapy it can be scary.  Be sure to communicate any obstacles you may have with your respiratory therapy team. The respiratory therapists are there to ensure your pressures are set at optimal levels to treat your unique condition and try different approaches as needed.

  • Chronic respiratory failure due to COPD, which includes chronic bronchitis, emphysema, severe neuromuscular disorders, and severe restrictive thoracic disorders

Breathe Easier with NIV

When your healthcare team decides that non-invasive ventilation is appropriate for you, they will work closely with you to identify the most appropriate device and mask for your particular needs. They will also instruct you on how to use the device as well as how to maintain it.

With NIV, the goal is to help you receive the breathing support you need while avoiding the potential complications of more invasive approaches.
