Measuring Respiratory Muscle Strength

Neuromuscular diseases, such as muscular dystrophy or multiple sclerosis, can weaken the muscles you need to help you breathe.

If your doctor wants to evaluate the strength of your respiratory muscles, you will come to the lab to get an assessment of your maximal respiratory pressures. The test measures the force generated by the diaphragm and chest muscles when you forcefully breathe in and out.

The lab sometimes also refers to this test as maximum inspiratory and expiratory pressure measurements.

The evaluation takes about 15 minutes.
