What is a spirograph test?

A spirograph test is a diagnostic procedure used to assess lung function by measuring the volume and flow of air during inhalation and exhalation. It typically involves the patient breathing into a device called a spirometer, which records various parameters such as forced vital capacity (FVC) and forced expiratory volume (FEV1). This test helps diagnose respiratory conditions like Asthma, chronic obstructive pulmonary disease (COPD), and other pulmonary disorders. It is non-invasive and usually takes only a few minutes to complete.
