COPD is an umbrella term for lung and respiratory diseases that make breathing difficult. Initially, the therapy was only available as an in-patient treatment within hospitals. Now, it can be done at home. Modern BiPAP machines are tabletop devices fitted with tubing and a mask. You simply put the mask over your nose and/or mouth to receive two levels of pressurized air. One pressure level is delivered when you inhale, and a lower pressure is delivered when you exhale. BiPAP machines often feature a “smart” breath timer that adapts to your respiratory patterns. It automatically resets the level of pressurized air when needed to help keep your breathing level on target. This therapy is a type of noninvasive ventilation (NIV). That’s because BiPAP therapy doesn’t require a surgical procedure, such as intubation or tracheotomy.
