Ventilator Testers are designed to evaluate the function of a ventilator by simulating the normal as well as pathological patient load conditions as would be present when attached to an actual patient. They are designed to be used for both adult and infant ventilators including conventional mechanical ventilation and high frequency ventilators. The tester provides the user documented test results to ensure patient safety. The test results are also useful for service, maintenance, troubleshooting and litigation purposes.
