Gas Flow / Ventilator Analyzers

The VT PLUS HF, an enhanced version of the popular VT PLUS general-purpose gas flow analyzer, evaluates the pressure, flow and volume delivered by a variety of devices. The VT PLUS HF features special modes designed specifically for testing mechanical patient ventilators, including High-Frequency Oscillatory Ventilators (HFOV). Some of the key features are: completely standalone operation, bidirectional flow measurements, vacuum and pressure measurements, liquid-pressure measurement, RS232 and printer ports, high-resolution graphical display, 21 ventilator parameters on the screen, User-accessible O2 concentration sensor, complete adapter kit, multiple units of measure for all parameters, minimum, maximum, average, absolute, and graph for all parameters, VT for Windows software providing an interface for recording/playback of calculated data for most VT PLUS HF functions, compatibility with ventilators utilizing bias-flow, PEEP, CPAP, pressure-support, and volume-support technologies, special HFOV mode for high-frequency oscillatory ventilator performance testing, special RT-200 emulation mode for use of familiar RT-200 functions. Optional calibrated AccuLung test lung available or combined in a kit.

VT MOBILE is a compact and portable general-purpose gas-flow analyzer designed to meet the needs of the traveling technician or engineer. This versatile tool evaluates performance of a wide variety of medical gas-flow/pressure devices and measures 16 ventilator parameters. Some of the key feature are: bidirectional flow (high- and low-flow ranges), volume, vacuum, pressure, and oxygen-concentration measurements, 16 ventilator parameter measurements, trending and statistical analysis of all measured values, onboard graphical display, portable and compact, RS232 for computer control, memory for storing results, VT for Windows PC software. Optional sensor assembly for temperature and humidity measurements and a calibrated AccuLung test lung.

The AccuLung precision test lung is a calibrated and portable lung simulator that presents a specific load comprised of a user-selectable compliance and resistance for the purpose of evaluating ventilator performance according to clinical expectation and manufacturers' specification.
