16 Monitoring Intravascular Oxygen Saturation
244
Changing the Lab Value Required for Entry
You can change the lab value required to be entered: Hb [g/dl], Hb [mmol/l] or Hct [%].
1 In the Setup <SO₂ Label> menu, select Hb/Hct Entry.
2 Select your preferred lab value and unit.
Preparing to Monitor with the M1011A Narrow
Module
In addition to the module, you need a Philips SO
2
Optical Module and a compatible fiber optic probe
or catheter. Use only the accessories listed as applicable for the intended measurement location in the
Accessories section.
Connecting the Optical Module
1 Connect the optical module to the SO
2
module. Allow the optical module to warm up before you
insert the probe/catheter and perform a calibration.
Although the warmup message disappears from the screen after one minute, it is preferable to let
the optical module warm up for 10 minutes for best accuracy.
2 Position the optical module to avoid contact with liquids. Fluid entering the catheter-optical
module connection will impair measurement performance.
3 Place the optical module on the catheter tray in the space provided and open the lid.
4 For instructions on the placement of fiber optic catheters/probes, refer to the documentation
provided with the accessory.
After Insertion
The SO
2
probe/catheter is thin and flexible, treat it carefully. Avoid kinking, bending or grasping the
probe/catheter with forceps or a hemostat. Damage to the fiber results in low intensity light and a
sudden decrease in intensity readings. Refer to the documentation provided with the fibre-optic
probe/catheter, paying special attention to any precautions, warnings or contraindications.
Secure the optical module directly attached or in close proximity to the patient, to avoid placing
excessive tension on the catheter, which would result in movement of the catheter tip from the optimal
position in the patient.
You must perform an in-vivo calibration once the probe/catheter is in place.
