2.2.6.2 High-Flow O2 Therapy Monitoring Board
The high-flow O2 therapy monitoring board is the core control part of high-flow O2 therapy of
the anesthesia machine. It is mainly used at a low flow of 0–60 L/min and can work
independently. The flow sensor is not welded on the board. The high-flow O2 therapy monitoring
board controls the O2/air flow through the proportional valve, and monitors and feeds back the
O2/air flow through the flow sensor. In addition, the high-flow O2 therapy monitoring board also
drives the three-way valve. This board is configured with high-flow O2 therapy software.
The high-flow O2 therapy monitoring board is installed in the same position as the auxiliary
O2/air flowmeter monitoring board.
