Handheld Infrared Spirometer for Lung Testing

This spirometer is a hand-held device used to check a patient's lung condition through a routine pulmonary function test. It uses an infrared signal acquisition mode to measure key respiratory parameters, including forced vital capacity, forced expiratory volume in one second, the ratio between the two, peak expiratory flow and forced expiratory flow at specified points along the flow curve.

Being compact and hand-held, the device is suited to a range of settings, from hospital respiratory departments and outpatient clinics to family use at home for patients who need to track their lung function over time as part of managing a chronic respiratory condition. Clinicians use the readings the device produces to help assess lung capacity and airflow, supporting diagnosis and ongoing monitoring of conditions that affect breathing.

Because spirometry testing typically involves the patient breathing directly into the device, appropriate use of disposable mouthpieces and cleaning between different users helps maintain good hygiene, particularly in clinical settings where the device is shared across multiple patients throughout the day.
