Spirometer with Automatic Disinfection

Abstract:

Given the increase in lung diseases in recent years, a turbine spirometer with semi-automatic disinfection and remote monitoring was designed and built at the University of the Armed Forces ESPE. Validation tests were performed with ten users of internal medicine and outpatient clinic of the Hospital Andino in the city of Riobamba and the cooperation of a pulmonologist of the hospital. The spirometry data was compared with data produced by a commercial spirometer of similar characteristics; no significant differences were found between the two devices (t = 3.27). Laboratory tests showed that the ozone disinfection system applied eliminates bacteria that can incubate due to the reuse of the equipment's nozzle, which will allow a reduction in the cost of spirometry tests performed by the hospital on its patients.
