Place the PWP Sensor on a flat surface such as a table or desk.
The patient should be seated comfortably in such a manner that their left hand is below their heart and their forearm is properly supported. The patient will need a clear view of the computer monitor to allow them to keep an eye on how much time is left in the PWP protocol.
The *PWP Senso*r precisely monitors the blood flow entering and exiting the capillary beds on the tip of the middle finger. If the patient’s hand is above heart level, the blood flow to the hand maybe reduced, this will reduce the quality of the heart rate signal.
The patient’s forearm must rest on the table or desk surface so that it is supported and parallel with the floor. The patient should not have to “reach” to place his or her hand in the PWP Sensor. If the patient must “reach” to place their hand into the PWP Sensor, unstable skin contact with the electrodes may result. This will cause signal artifact and insufficient data collection.
Have the patient place their index finger, middle finger and ring finger in the PWP Sensor. Make sure that the tip of the patient’s middle finger extends all the way to the back wall of the PWP Sensor. The wall or post contains a temperature sensor and direct contact is needed to accurately measure the patient’s skin temperature.
