How do PrO2 devices differ from a Spirometer?

A spirometer is a simple device for measuring the flow and volume of air. This essentially overlooks the primary mover… EFFORT from contracting respiratory muscles. PrO2 devices measure the muscle and lung function combination, which equals RESPIRATORY PERFORMANCE. One device, the PrO2, is used to measure and record overall lung performance, which can be done at home or in the clinic, and it also provides the necessary training to improve lung function. The PrO2 provides functionality beyond simple flow measurements found in a spirometer. It is a proven muscle conditioning tool tested in multiple university studies.
