Forced Vital Capacity is the max expiration after taking a full breath, it\'s an important examination content in chest-lung disease and respiratory health, and it is indispensable testing project in modern Pulmonary inspection.

At the same time, it has great significance in respiratory diseases, differential diagnosis, treatment evaluation and selection of surgical indications.

Thus, with the rapid development of clinical respiratory physiology, clinical applications of lung capacity inspection are also gaining popularity.

The Bluetooth Spirometer SIFSPIRO*1.1 is small in volume, low in power consumption, convenient in operation and portable. With high-definition display screen, the device is concise and fashion. It is only necessary for patient to breath in fully and seal the lips around the mouthpiece and blast the air out in best times for measure, then the display screen will directly show the Forced Vital Capacity(FVC), Forced Expired Volume in one second (FEV1), Peak Expiratory Flow (PEF) with the high veracity and repetition 

Major Applications and Scope
The Bluetooth Spirometer SIFSPIRO*1.1 is a hand-held equipment for examining lung function. The product is fit for hospital, clinique, family for ordinary test. It\'s requested that the user operates it according to user manual, doesn\'t need carry on specialized training, so the operation of the device would be as simple and easy as possible.

 Features
1.**-Ultra-thin design, concise and fashion.
2.**-Small in volume, light in weight and convenient in carrying.
3.**-Low power consumption.

3.**-Data memory, delete, upload and review.
4.**-Trend chart display.
5.**-Scalering (Calibration).
6.**-Information prompts when volume or flow goes beyond the limits.
7.**-Automatic power off when there is no operation in one minute.
8.**-Rechargeable lithium battery and with charging tips.
9.**-Battery power display.
