Create a blood pressure Y-tube
The blood pressure Y-tube is a piece of custom test equipment that connects the device to the test
setup. The Y-tube is composed of a modified blood pressure hose and a Y-type fitting. Follow these
instructions to create a Y-tube.
1.
Cut a 4500-30 blood pressure hose approximately 6 inches from the connector that connects
to the device.
2.
Split the end of the dual-lumen hose to create two separate hoses. Make sure not to puncture
either hose.
3.
Insert one end of the Y-type fitting into each end of the hose.
