BREATHABLE GAS SUPPLY SYSTEM, CONTROL METHOD THEREOF AND COMPUTER PROGRAM PRODUCT IMPLEMENTING THE METHOD

摘要

A breathable gas supply system comprises a flow sensor, a control unit and a storage unit. The flow sensor detects a gas state of a flow channel. The control unit provides an initial template value and continuously receives sampled breath values from the flow sensor to repetitively perform a first breath sampling process so as to generate a first template value for replacing the initial template value; then the control unit continuously receives sampled breath values from the flow sensor to repetitively perform a second breath sampling process so as to generate a second template value; finally the control unit integrates the first template value and the second template value to obtain an updated template value for replacing the first template value, and the aforesaid operations are repeated to generate a new second template value to obtain a new updated template value. The storage unit stores the first template value, each second template value and each updated template value. A method of controlling the breathable gas supply system and a computer program product implementing the method are also provided.

1. A breathable gas supply system for providing a breathable gas to a patient via a flow channel, the breathable gas supply system comprising:
a flow sensor for detecting a gas state of the flow channel; a control unit electrically connected with the flow sensor, the control unit providing an initial template value and continuously receiving a sampled breath value from the flow sensor for repetitively performing a first breath sampling process; wherein when the first breath sampling process has been performed for a first preset number of times, the control unit generates a first template value for replacing the initial template value based on all first breath sampling processes; after the first template value has been generated, the control unit continuously receives the sampled breath value from the flow sensor for repetitively performing a second breath sampling process; when the second breath sampling process has been performed for a second preset number of times, the control unit generates a second template value based on all second breath sampling processes; and the first template value and the second template value are integrated to obtain an updated template value for replacing the first template value, and the above-cited operations are repeated to generate a new second template value so as to obtain a new updated template value; and a storage unit electrically connected with the control unit to store the first template value, each second template value and each updated template value.
