Description

The Korr Medical Technologies RSS 100 is a complete spirometry system for use in any application where airway flow and pressure are measured.

The RSS 100 research spirometry system measures gas flow 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 end expiratory pressure, etc.

The RSS 100 has a graphic liquid-crystal display, 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 to acquire waveforms and data produced by the RSS 100. 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 instrument.

Features

  • Custom Microsoft Windows software for displaying, storing, and reviewing data.
  • Monitor is fully functional as a stand-alone device. LCD screen displays waveform and parameter data in real time.
  • Embedded microprocessor calculates flow rate and provides correction for gas density, viscosity, temperature, barometric pressure, and airway pressure.
  • Calculates over 15 ventilatory parameters.
  • Integrated breath detection algorithm automatically detects start and end of breath.
  • Custom fixed-orifice, differential pressure pneumotachs require no user calibration and remain accurate even under extreme clinical conditions.
  • Built-in calibration function for linear "Fleisch" pneumotachs. Calibration stored in non-volatile memory.
  • Serial RS232 and analog outputs provided for simple computerized data collection.

Calculated Parameters

  • Positive End Expiratory Pressure

The RSS 100 works with precision molded fixed-orifice pneumotachs provided with the unit. The proprietary precision molded pneumotachs do not require any user calibration and are available in adult and neonatal sizes. These pneumotachs are robust even under extreme heat and moisture conditions found in critical care conditions. The RSS 100 is also designed to work with a wide range of linear (Fleisch) differential pressure pneumotachs.
