Cadwell Sleepmate Instrucciones De Uso página 3

Intended use
The Cadwell Sleepmate Disposable Airflow Sensor is intended to detect patient nasal and/or
™
oral breathing during sleep research and clinical studies of sleep.
Instructions for use
Grasp the sensor at the exposed silver end, and insert one half of the sensor's silver end into
the interface cable, then push on the neck of the sensor and insert the remainder into the
cable. Even after fully inserting the connector, a portion of the silver
connector may remain exposed. Then fold the nasal extensions at an angle away from
the face to insure that they are in the flow of air. The side of the sensor with the SILVER
sensor lines should be facing toward the user's skin. The one channel cable connector will
point off to the patient's left.
Two Channel Output
The Two channel output allows you to see the Oral and Nasal signals separately. To use this
option requires a slight modification to the sensor and the use of the two-channel cable.
Step 1: Place the sensor on a flat surface with the BLACK lines facing away from the patient.
Note that both ends have two silver connector plates; however, on the left end there
is a green colored half circle bridging the circuit.
Step 2: With scissors or knife cut the green half circle away from the LEFT end of the sensor.
Now both ends of the sensor should look the same.
Step 3: Connect one cable to each end of the sensor.
Step 4: To obtain the Oral signal plug the red and black lead pair "Oral" into one channel
on the recorder.
Step 5: To obtain the Nasal signal refer the red and black lead pair labeled "Nasal" into a
second channel on the recorder. Ensure the sensor is securely attached to the patient
as described and you have clear, reliable signals prior to lights out.

One Channel Output
The Adult and Medium sensors can be used as a Single channel output or a two-channel
output. The Single channel output is the default setup; the Oral and Nasal airflow signals are
combined on one channel. Simply plug a sensor into the single channel cable and then insert
the connectors into the recording device. Ensure the sensor is securely attached to the patient
as described and you have clear, reliable signals prior to lights out.
Sensor Placement
Apply tape intended for facial use to the ends of the sensor and place the sensor between the
nose and mouth. Insure that the oral and nasal probes are directly in the flow of air. The
sensor works best when the sensor lies flat against the skin between the nose and mouth.
Run the cable over the patient's ear and apply a small piece of tape to the neck to provide a
strain relief for the lead wire. Ensure the sensor is securely attached to the patient as
described and you have clear, reliable signals prior to lights out.
Cleaning
This sensor was designed for a single patient use. The lead wire can be cleaned by rubbing
with any cleansing agent that is not corrosive toward plastic. The entire assembly must
be completely dry before using again to insure patient safety. For sterilization
implement a standard procedure for gas sterilization. Do not autoclave this product. Use the
molded ends of the connectors when removing the connector from the junction box.
