3.1 Introduction
SPM-D is a device for testing pulmonary function, combining with professional pulmonary function software, it is used to test the patient’s respiratory function and lung status; it adopts differential pressure collection principle to measure FVC, SVC, MVV, MV and relative parameters, real-time displays respiratory waveform, which is applicable for diagnosis and response evaluation of lung diseases (such as asthma, COPD, pulmonary fibrosis and cough, etc. ), preoperative safety evaluation and routine physical examination, etc. It can be widely used in many scenarios, such as respiratory medicine, thoracic, anesthesiology, surgery, prevention and control institutions of occupational disease, physical examination institutions, etc.
3.2 Features
1) Measure and display over 100 parameters related to FVC, SVC, MVV and MV functions.
2) Display trend chart and respiratory waveform tested, recommend the optimal test curve intelligently.
3) With management functions of user information and case data.
4) Built-in multiple predicted values, which can be set manually.
5) BTPS self-correction function, measure environment parameters automatically.
6) Pulmonary function assessment function.
