1. Key troubleshooting methods for high flow oxygen therapy machines
The core troubleshooting methods for high flow oxygen therapy machines revolve around oxygen concentration maintenance, pressure alarm processing, and flow stability adjustment. The following is a detailed analysis of each item. one Low oxygen concentration • Flow meter inspection: Ensure that the flow control knob has not been accidentally closed or lowered, and align with the doctors recommended scale line during operation. • Connection inspection: Check whether the nasal oxygen tube is twisted, flattened or detached, ensuring that the interface is tight and not loose. Filter maintenance: If the primary sponge filter turns black or is clogged with dust, it needs to be cleaned 1-2 times a week and thoroughly dried; Advanced bacterial filters that turn yellow or exceed their expiration date (usually 3-6 months) need to be replaced by contacting after-sales service. Environmental adaptation: Avoid placing the machine in a confined space, maintain a 20-30 centimeter heat dissipation distance around it, and stay away from walls and other obstructions. Molecular sieve maintenance: If the above operations are ineffective, it is considered that the molecular sieve has failed and professional personnel need to intervene for maintenance. two Abnormal pressure alarm • High pressure alarm: Due to blockage of oxygen pipelines, it is necessary to promptly clear the pipelines. Sensor issue: Check if the pressure sensor settings are correct and replace with a new sensor if necessary. three Unstable oxygen flow rate • Flow meter calibration: Calibrate flow meter parameters to ensure accurate values. Impurity cleaning: Disassemble and clean the inside of the
2. Ultrasonic oxygen concentration and volume flow rate
Different models of ultrasonic oxygen sensors have significant differences in the detection range of oxygen concentration and volume flow rate, and the appropriate model should be selected according to the actual flow requirements.
. 1. Comparison of core parameters of different models Gasboard-7500H oxygen concentration detection covers the full range (0-100%), among which the PSA oxygen concentrator special detection is applicable for oxygen concentration narrowed down to 20.5% -95.6%, with a flow detection upper limit of 10L/min, suitable for small oxygen production equipment. On the basis of maintaining full range oxygen concentration detection, the ultrasonic oxygen flowmeter has a flow detection upper limit of up to 240L/min, which is suitable for large-scale industrial sail oxygen or high flow medical oxygen supply systems. Gasboard-8500FS-L40, as a medium range model, has a flow detection upper limit of Sonna 40L/min and is suitable for medium-sized oxygen production scenarios.2. Selection logic sorting • Ultra low flow (≤ 10L/min): Priority should be given to 7500H, as its PSA special parameters have high compatibility with the application scenarios of oxygen generators. • Medium high flow (10-40L/min): It is recommended to use 8500FS-L40 balance accuracy and range. • Ultra high peak flow (>40L/min): An ultrasonic oxygen flowme
