Respiration monitoring devices
Devices such as spirometers and sleep recorders are employed to monitor respiration for diagnosis purposes or to optimise therapies. Spirometers perform simple lung function tests to examine airway of lung diseases such as asthma or chronic obstructive pulmonary disease. They measure the respiratory air flow and determine the inhaled and exhaled total respiratory volumes (inspiratory and expiratory volumes) and other lung function statistics. These devices are typically small, lightweight portable systems that are used in the doctor's surgery, patient's home and workplace of wherever symptoms appear.
