Pressure wire systems require preparation before they are introduced into the catheter systems. Typically, they should be positioned flat on the table, ideally at the level of the patient’s heart. The wire housing should be flushed with saline to activate the sensor prior to the pressure wire being connected to the console system. When using those with plugin connectors, care is required to avoid the connector becoming wet. Once connected, an onscreen display will indicate the wire is “zeroing”. With bluetooth systems, onscreen instructions should be followed carefully. Only once the pressure wire systems have fully activated should the wire be removed from the housing and the tip be shaped.
