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.
