FEATURES OF THE PRESSUREWIRE RECEIVER
The PressureWire Receiver ensures secure communication for accurate fractional flow reserve (FFR) results.
- The PressureWire transmitter and receiving system lock to each other at calibration using a unique identification code. The receiver cannot receive pressure from any other PressureWire X guidewire being used in the vicinity.
- The system uses advanced frequency-hopping spread spectrum (FHSS) technology and very low radio power to avoid interfering with or being disturbed by other systems in the cardiac cath lab.
- The system changes radio frequency 400 times per second so that even if there are several interfering radio sources it will always locate other available frequencies.
- Mobile phones, computer networks or x-ray equipment will not disturb the radio signal.
- If a power failure occurs, the receiving system stores the last connected PressureWire X guidewire in its memory for automatic reconnection.
The “Plus” button:
- Increases pressure offset by +1 mmHg or
- Increases reference level output in Refout mode
The “Connect” button is:
- Pressed once to connect to PressureWire X guidewire
- Pressed and held > 3 second to enter Refout mode
- (While in Refout mode) Pressed once to exit
The “Minus” button:
- Decreases pressure offset by -1 mmHg or
- Decreases reference level output in Refout mode
PERFORMANCE IN A HEMODYNAMIC RECORDING SYSTEM
The PressureWire X guidewire is a key component of an FFR-enabled hemodynamic recording system. When the PressureWire Receiver is plugged directly into the recording system front end, users can count on:
- FFR presented in real time on existing monitor screens
- Recording and analysis of FFR recordings on screens inside the cardiac cath lab and control room
- Configurable beat- or time-based pressure averaging
- Easy software equalization of Pa and Pd pressures*
- Complete documentation of FFR measurements
