This complete spirometry system is for use in any application where airway flow and pressure are measured. Flow is measured using the differential-pressure method. As gas flows through the pneumotach, the microprocessor-based system converts the measured differential pressure to volumetric flow rate. Flow and pressure measurements are used to calculate several ventilator management parameters such as respiratory rate, lung compliance, tidal volume, minute volume, positive and expiratory pressure, etc.
This spirometer has a graphic LCD which shows flow, pressure, and volume strip-chart plots as well as flow-volume and pressure-volume loops. Calculated parameters are also displayed on the screen.
The system can also be interfaced to a computer through a serial data port. A Windows™ software program is available separately and permits acquisition of waveforms and data obtained by the spirometer. It may be displayed, stored or viewed using this program.
Flow, pressure, volume, and auxiliary pressure signals are available as analog outputs for convenient and reliable interfacing to a strip chart recorder, oscilloscope or other instruments.
This system works with precision molded fixed-orifice pneumotachs. They do not require any user calibration and are available in two sizes. These pneumotachs are robust even under the extreme heat and moisture conditions. This system is also designed to work with a wide range of linear (Fleisch and Hans Rudolph) differential pressure pneumotachs.
This system is supplied with software, small and large sensors with tubing, RS-232 serial cable, standard North American power cord and user’s manual.
