AI Technical Summary
Existing oxygen supply equipment struggles to simultaneously ensure timely oxygen supply response, smooth control, oxygen utilization, and long-term adaptability under complex and ever-changing real-world conditions. It cannot achieve synchronous adaptive oxygen supply control with the user's breathing rhythm, and its oxygen supply adaptability and safety are insufficient.
By acquiring and unifying the timestamps of respiratory flow and respiratory pressure signals, preprocessing and signal quality assessment are performed, respiratory feature parameters are extracted, feature vectors are constructed and combined with the basic parameter set to identify the respiratory phase, respiratory demand score is calculated, oxygen supply parameters are corrected using dynamic fusion weights and oxygen supply target prediction models, and safety risk assessment and threshold judgment are performed to generate the final control command.
It achieves high-precision matching with the user's breathing rhythm under complex conditions, improves the timeliness of oxygen supply response, control smoothness and oxygen utilization, ensures the safety and stability of oxygen supply, and enhances user comfort.
