MSA99 Pulmonary Function Analyzer
Technical Specifications
1. The portable pulmonary function measurement instrument can be used tomeasure vital capacity (VC), forced vital capacity (FVC), Maximum Ventilatory Volume (MVV). Measurement algorithm refers to the ITS, ERS standards of the American Thoracic Society (ATS)
2. Adopting pressure-flow sensor, sensitive, precise, easy to launder, clean and durable
3. All parameters can be displayed on the oversized screen(320x240), built-in memory can store maximum 300 cases of patient measurement results
4. The instrument can calibrate automatically, all English operation, more convenient to operate
5.110mm thermal printer built-in, can print out a clear clinical report, predicted value, measured value
6. Measurement of breathing time: VC time 50 seconds, FVC measuring time 25 seconds, MVV time 12 seconds, in favor of the coordination between patients and the device
7. Compact and flexible
