The STS is a handheld spirometer intended to measure lung function in adult patients while at rest (including spirometry and lung volumes). The STS is to be used by either a physician, respiratory therapist, or technician.The STS device is pulmonary function testing device that measures both flow/volume (spirometry), lung volume and resistance/compliance parameters. It is a multi-use device that should be used with a compatible single-use, disposable mouthpiece which incorporates a viral-bacterial filter protecting the patient from the internal components of the device. The device is battery operated allowing for approximately 40 operating hours between charges. The measurement results, which are transmitted via Bluetooth, are displayed on the physician’s computer via the STS software/App.
An electrically-powered device designed exclusively for professional use to measure several or all respiratory gas volume and flow parameters for evaluation of basic pulmonary function [e.g., vital capacity (VC), peak expiratory flow (PEF), forced expiratory volume (FEV), and forced expiratory flow (FEF)]; it may also perform pulse oximetry. It is typically a hand-held instrument with a mouthpiece which communicates with a computerized unit (e.g., analysis system, graph recorder, tablet). It is used to help diagnosis and monitoring of chronic pulmonary disorders such as asthma, emphysema, or bronchitis, and potentially heart disorders.
