Using The Direct Pressure Measurement Function (Real-Time Pressure Sensing Rtp) - Stryker PneumoSure Gebrauchsanleitung

1. The gas heating is automatically started at the START of the insufflation:
Press the START function field. The gas is automatically heated to 37 °C.
2. Stopping gas heating:
Press the STOP function field. Gas heating is switched off.
3. Pull the tube set plug from the device connection.
When a defective heating tube set is used,
• the display depicts a crossed out symbol
• the text line reads Gas heater defective <-> Call service,
• and an acoustic signal is emitted (3 short beeps).
Insufflation can be continued in this case, but the heating function is not avail-
able.
The device is equipped with a temperature sensor to protect against overheating,
caused for exemple by external heat sources. If the temperature sensor mea-
sures a temperature >42°C, the status field of the display depicts Gas tempera-
ture >42 °C; 3 accoustic signals are emitted in addition, the HEATING symbol is
crossed out . Insufflation and the heating function are halted. After 3 seconds,
the display depicts Disconnect luer lock alternating with Cool down tube until
the insufflation is manually restarted.
WARNING!
Unplug the cable of the heating tube from the device if the temperature sensor
measures a gas temperature exceeding >42 °C. Hot gas in the abdomen can lead
to serious injuries.
1. Disconnect the insufflation tube from the trocar or Veress needle.
2. Press the START function field. The device insufflates without heating the
gas.
3. Let hot gas escape until the tube is only warm to the touch and then recon-
nect the device again.
4. Continue surgery without gas heating.
1. Check gas heating after surgery using a different tube. Turn the device off
and back on after approx. 10 seconds have expired. Gas heating is reactivat-
ed.
2. Should the error message be displayed again, you can continue using the de-
vice without gas heating by observing the risks for hypothermia.
3. Call an authorized service technician to check/fix the gas heating.
5.6.1 Using the direct pressure measurement function (Real-Time
Pressure Sensing RTP)
The insufflation tube sets "Heated tube set with Real-Time Pressure Sensing
(RTP)" and "High Flow tube set with Real-Time Pressure Sensing (RTP)" are
equipped with a sensor line which enables continuous measuring of the abdom-
inal pressure. The insufflation line must be connected to one trocar and the mea-
suring line (sensor line) to a second trocar. This set-up enables the PNEUMO SURE
XL High Flow Insufflator to directly measure the actual abdominal pressure while
in High Flow-, Pediatric- and Bariatric operating mode. The "Real-Time Pressure
Sensing" is deactivated during the Vessel Harvest operating mode. The use of an
insufflation tube without a second measurement/sensor line only allows the in-
termittent measuring of the pressure.
Insufflation is initially always started intermittently. Availability of the "Real-
