3. © 2008 Masimo Corporation RAD-57 Operation / Startup Sequence Place sensor on finger (relatively clean & dry) Press “Power” button Verify All LED’s light up and a 1 second tone is heard* Startup mode begins All preset configurations are displayed Scrolling zeroes 0 – 0 – 0 and flashes dashed lines May take up to 25 seconds Do not move sensor during startup When complete reading is displayed Begin patient monitoring Defaults to pulse rate and oxygen saturation reading “PI” bar graph displays strength of arterial perfusion * Refer to operator’s manual for additional verifications prior to patient monitoring.

4. © 2008 Masimo Corporation RAD-57 Operation / Sensor Placement Sensor placement is very IMPORTANT When possible, use ring finger, non-dominant hand Insert finger until the tip of finger hits the STOP Block Sensor should not rotate or move freely on finger LED’s (red light) should pass through mid-nail, not cuticle There is a top and bottom, cable should be on top (nail side) Optimal LED path

5. © 2008 Masimo Corporation RAD-57 Operation / Pulse Rate and Saturation Display after Startup Oxygen Saturation on top in Red Pulse Rate on bottom in Green Green PI scale, indicates strength of arterial pulse Low SIQ LED indicates poor SpO 2 signal quality Press “Display” to display % carboxyhemoglobin Press “Bell” to silence alarms Display button toggles from SpO 2 to SpCO PI Scale Low SIQ LED Alarm Silence LED Battery level

6. © 2008 Masimo Corporation RAD-57 Operation / Alarms When parameter is violated, audible alarm will sound, parameter will flash Preset at factory: Sp0 2 (oxygen saturation) Low: 90% High: none Pulse Rate Low: 50 High: 140 SpCO (carboxyhemoglobin) Low: none High: 10% Alarms adjust: Press “Mode/Enter” twice Press “Next” key to scroll through parameters Use up and down keys to adjust Changes remain until user restores to factory defaults Alarm Indicator (flashes)

7. © 2008 Masimo Corporation RAD-57 Operation / Measuring CO Press “Display” button for SpCO reading To scroll back to SpO 2 mode press “Display” again Carboxyhemoglobin displayed in % on top “CO” displayed on bottom confirming mode Real-time SpCO indicator continuously reads SpCO Green: 1-3% Yellow: 4-11% Red: 12% and above Confirm abnormal readings by taking several measurements on different fingers and average the readings Slow: Low SpCO Confidence Fast: SpCO Alarm CO label when SpCO is displayed

9. © 2008 Masimo Corporation RAD-57 Operation / Troubleshooting Will not power on Check battery compartment Replace batteries Continuous Startup mode (Scrolling zeroes 0 – 0 – 0 and flashes dashed lines) Shield sensor from flashing lights, strobes or high ambient light with Masimo Light Shield* Try other fingers Single battery level indicator flashes (with audible alarm) Battery level too low Replace batteries immediately “Err” message Return for service, Call 800-326-4890 Continuous Speaker Tone Power down and remove batteries Return for service, Call 800-326-4890 * Contact your Masimo sales rep to order a Masimo Light Shield.

10. © 2008 Masimo Corporation RAD-57 Operation / Light Shield Use Face protrusion of light shield down, and insert the end of the sensor into the hole Ensure that sensor hits the back of the light shield Orient the sensor so the cable is coming out of the top of the hole while in the light shield Open the sensor by applying pressure from the top and bottom of the light shield Insert finger until the tip of finger hits the STOP Block LED’s (red light) should pass through mid- nail, not cuticle Orient the sensor so the cable is running over the top of the patient’s hand Optimal LED path Apply pressure to open sensor Protrusion

11. © 2008 Masimo Corporation RAD-57 Operation / Improving Accuracy The Rad-57 is designed with an accuracy of +/- 3 digits with a range of 1% - 40% for one standard deviation (67% of patients) Example: A reading of 10% could have a range from 7% - 13% Measurements may vary from reading to reading, even on the same patient, within the accuracy specification Proper probe placement may improve accuracy If an abnormal level of CO is detected, always confirm by measuring other fingers and average Flashing lights, strobes or high ambient light may interfere, use a Masimo Light Shield or other means of shielding
