NOx analyzer NOX 500

NO2nitric oxidefor medical devices

Simultaneously monitors Nitric Oxide and Nitrogen Dioxide promoting better oxygenation of the lungs. Used to treat pulmonary hypertension. The NOx 500 is a nitric oxide (NO) and nitrogen dioxide (NO2) monitor based on compact electrochemical cells, which must be directly connected to electrical power to function. Easy to use, it avoids the need to preheat the sensors and has simple and efficient calibration. In case of lack of oxygen in the respirator, the equipment has an automatic cut-off of nitric oxide, the only one in the world with this device. It was designed to monitor patient-delivered NO used in the therapy of Adult respiratory distress syndrome (ARDS) and pulmonary hypertension in ventilated patients. NO2, a more toxic by-product with no therapeutic use, is also monitored. The NO measurement has a resolution of 0.1 ppm and specified accuracy up to 100 ppm, while the NO2 measurement has a resolution of 0.1 ppm and specified accuracy up to 50ppm. The gas to be monitored is constantly sampled at a constant flow (300 ml/min), with low dead space, in the “sidestream” system. The cells are extremely sensitive to high humidity, and all available means must be used so that gases with these conditions do not penetrate into the equipment. Measurements are represented on an easy-to-view liquid crystal display and can be printed or transferred to a personal computer via a standard RS 232C serial output. The NOx 500 includes high and low level alarms for NO, high level for NO and a safety valve that can be activated at values ​​determined by the operator, cutting off the supply of NO to the patient if it reaches very high levels.
