So, how exactly does breath training lower blood pressure? Craighead points to the role of endothelial cells, which line our blood vessels and promote the production of nitric oxide — a key compound that protects the heart. Nitric oxide helps widen our blood vessels, promoting good blood flow, which prevents the buildup of plaque in arteries. "What we found was that six weeks of IMST [inspiratory-muscle strength training] will increase endothelial function by about 45%," Craighead explains.

It has long been known that deep diaphragmatic breathing — often used during meditation or mindfulness practices — can help lower blood pressure too. Muscle training with the PowerBreathe device works in a similar way, engaging the breathing muscles and promoting the production of nitric oxide.

My opinion:  Device not really necessary, controlled breathing exercises and meditation are probably just as effective.  The article highlights this multiple times and uses existing research.  The PowerBreathe device is just a shortcut for people who are looking to maximize results and minimize effort.  I'm not sold.
