• Do not modify or alter the sensor in any way. Alteration or modification may affect performance and/or accuracy.
• If the sensor has been stored in a cold environment, it will need to be brought to room temperature to ensure a correct
reading.
• The sensor may not adhere well on extremely diaphoretic patients.
• The RAM® dual cable must be connected to a compatible monitor with Masimo rainbow SET technology with the RRa
feature enabled.
• RAS-45 is not for Apnea monitoring or Apnea alarm.
• Caution: Replace the sensor when a replace sensor message is displayed, or when a low SIQ message is consistently
displayed after completing the low SIQ troubleshooting steps identified in the monitoring device operator's manual.
• Note: The sensor is provided with X-Cal® technology to minimize the risk of inaccurate readings and unanticipated
loss of patient monitoring. The sensor will provide up to 120 hours of patient monitoring time. After single-patient use,
discard sensor.
INSTRUCTIONS
A. Site Selection:
Site should be hair-free, cleaned of debris and dry prior to sensor placement. Use an alcohol swab to clean the application
site, if needed.
1. Refer to Fig. 1. The measuring site is the upper chest. It is recommended that the center of the sensor pad is placed
sub clavicular, at the 2nd intercostal towards the right of the patient's chest.
B. Applying the Sensor:
1. Refer to Fig. 2. Gently pull the small tab away from the liner to expose the sensor adhesive.
2. Refer to Fig. 3. Gently place the sensor onto the application site so that the "Masimo" label is visible.
3. Refer to Fig. 4. Apply pressure all around the perimeter of the sensor to ensure the adhesive is secure to the patient's
skin. Avoid contact with the exposed sensor adhesive.
4. Ensure that the skin of the patient is relaxed and not stretched in any way and that there are no skin folds under the
sensor pad.
5. Refer to Fig. 5. Remove the two piece sensor liner from the top of the sensor.
6. Refer to Fig. 6. Remove the anchor liner and attach the anchor pad to the patient's chest at the level of the armpit.
7. Route and secure the sensor cable to reduce the risk of patient entanglement or strangulation.
C. Connecting the RAS-45 Inf/Neo Sensor to the Acoustic Respiration Patient Cable:
1. Refer to Fig. 7. Insert the sensor connector into the cable connector, until it locks in place.
2. Confirm that the RAS-45 Inf/Neo sensor is properly applied to the patient's application site and also connected to the
patient cable.
3. Confirm that the monitor is able to detect a signal (refer to device manual).
Note: If the signals are not detected, select another site on the chest using a new sensor.
D. Disconnecting and Removing the RAS-45 Inf/Neo Sensor:
Warning: Disconnect the cable from the sensor prior to removing the sensor from the patient.
1. Refer to Fig. 8. Grasp the cable connector and the sensor connector and pull to disconnect.
2. Gently pull on the sensor adhesive tab to stretch and release the sensor from the application site.
3. Gently pull on the anchor pad to lift and remove the adhesive from the patient.
Note: When the RAS-45 Inf/Neo sensor is off the patient and is still connected to the system, the sensor may pick up background
noise and report a measurement. The sensor should only be connected to the cable while performing patient monitoring. If the
patient is not being monitored, the sensor should be disconnected from the cable.

* Respiration rate accuracy for the RAS-45 Inf/Neo sensor has been validated for the range of 4 to 120 breaths per minute in bench top testing. Clinical
validation was performed with the RAS-45 Inf/Neo sensor and monitoring device for up to 82 breaths per minute in infant and neonatal subjects.
