Bird Sentry™ Blender Chapter 1: Introduction The Bird Sentry blender is a compact air/oxygen gas mixing device which incorporates the use of a battery powered oxygen analyzer/monitor. The gas mixing device (blender) provides for precise mixing of medical grade air and oxygen, while the analyzer measures the selected oxygen concentrations from the blender's gas flow and samples and displays these measured concentrations on a digital display.
Chapter 1: Introduction Bird Sentry™ Blender Front Panel Functional Description A Display A digital liquid crystal display provides direct readout of oxygen concentrations in the range of 0 to 100%. It also displays CAL when the calibration mode is entered. B Battery Low Indicator The low battery indicator appears on the LCD display when the power supply voltage drops below acceptable limits. When the LOW BAT icon is visible, the batteries should be replaced.
Bird Sentry™ Blender Chapter 1: Introduction F Calibrate Key When the keypad is unlocked, the CAL key is used in conjunction with the UP and DOWN arrow keys to calibrate the Bird Sentry blender. When the CAL key is pressed, CAL appears on the LCD readout for one second, and then the measured calibration. The % sign will flash at a one per second rate. When the calibration value is set, pressing the CAL or LOCK key will cause the unit to exit the calibrate mode and return to normal operation.
Chapter 1: Introduction Bird Sentry™ Blender N Low Alarm Display Control The low alarm setting is displayed at all times just below the LOW icon on the LCD readout. The indicated value represents the oxygen percentage at which the low alarm will be activated. In the Low Alarm Set mode, the LOW icon will flash at a one-second rate. In a low alarm condition, the low alarm value will flash in conjunction with the low alarm LED.
Bird Sentry™ Blender Chapter 1: Introduction B Outlet Port See Figure 1, letter O. C O2 Sensor Port A sampling port for the oxygen sensor. It allows 3 LPM of mixed gas from the blender to flow over the sensor membrane. The port is located on the back side of the plate. D Medical Air Inlet Adapter See Figure 1, letter P. E Oxygen Inlet Adapter See Figure 1, letter Q.
Chapter 1: Introduction Bird Sentry™ Blender What You Will Need to Operate the Blender ● Pressurized Oxygen. The compressed oxygen source must provide clean and dry, medical grade oxygen at a line pressure of 40 to 60 PSIG (2.8 to 4.2 bar). ● Pressurized Air. The air source must provide clean and dry, medical grade air at a line pressure of 40 to 60 PSIG (2.8 to 4.2 bar).
Bird Sentry™ Blender Chapter 2: Operating Procedures Before placing the Bird Sentry blender into clinical use, the performance check described in Chapter 3 should be performed. Refer to Appendix C for Setup and Installation. Monitoring To begin monitoring, press the ON/OFF button located on the front panel (if necessary). Monitoring will begin immediately.
Chapter 2: Operating Procedures Bird Sentry™ Blender High Alarm Setting To adjust the high alarm setting: 1. Press the LOCK key to unlock the keypad. 2. Press the HIGH SET key. The HIGH icon will start to flash. 3. Use the UP and DOWN arrow keys to set the high alarm to the desired value. The high alarm value cannot be set closer than 1% from the low alarm value. For example, if the low alarm is set at 50%, the system will not accept a high alarm setting less than 51%.
Bird Sentry™ Blender Chapter 2: Operating Procedures Calibration Procedures The Bird Sentry blender should be calibrated before being placed into clinical use. Thereafter, CareFusion recommends calibration of the unit on a daily basis. Frequent calibration will have no adverse effect on the performance of the Bird Sentry blender. Calibration should also be performed upon replacement of a sensor or when point-of-use elevation changes by more than 500 feet or 150 meters.
Chapter 2: Operating Procedures Bird Sentry™ Blender Automatic Calibration to Room Air The Bird Sentry blender can be quickly calibrated to room air (20.9%) using a quick shortcut command. This function saves time by setting the calibration value to 20.9% without scrolling the display. To use this function: 1. Place the external probe in room air. 2. Press the LOCK key to unlock the keypad. 3. Press and hold down the CALIBRATE key.
Bird Sentry™ Blender Chapter 3: Pressure Differential Alarm/ By pass Check Before placing the Bird Sentry blender into clinical use, periodically perform the following tests. Warning! If the Bird Sentry blender does not function as described in this chapter, contact your CareFusion distributor or CareFusion. DO NOT use the Bird Sentry blender until correct performance has been verified. Connect the 50 ±5 PSIG (3.4 ±0.
Chapter 3: Pressure Differential Alarm/Bypass Check 12 Bird Sentry™ Blender PROCEDURE BIRD SENTRY™ RESPONSE 11. Slowly raise the pressure of air regulator to 50 PSIG and back to 0 PSIG while observing the oxygen hose end in beaker. No bubbles should be observed. Audible alarm sounds. 12. Dry and reattach the oxygen inlet hose to the regulator. No response. L1383 Rev.
Bird Sentry™ Blender Chapter 4: Troubleshooting Problem Potential causes and solutions Oxygen concentration discrepancy between oxygen concentration selection knob and actual reading on display. 1. Monitor out of calibration. Calibrate. Refer to Ch.2, Calibration Procedure. 2. Sensor exhausted. Replace. Refer to Ch. 6, Service and Maintenance. 3. Outlet flows are below specified range. Correct flow. Must be above 2 LPM. 4. Gas supply contaminated.
Chapter 4: Troubleshooting 14 Bird Sentry™ Blender Problem Potential causes and solutions Sensor will not calibrate. 1. Sensor cell exhausted. Replace. Refer to Ch. 6, Service and Maintenance. 2. Sensor cable or holder defective. Return to CareFusion Corporation. 3. Monitor defective. Contact CareFusion distributor or CareFusion Corporation for repair. Sensor will calibrate, but takes too long to return to 21% ±2% oxygen in air (2 to 5 minutes) when performing the daily check procedure.
Bird Sentry™ Blender Chapter 5: Cleaning the Bird Sentry™ Blender Warning! Explosion hazard. DO NOT gas sterilize the Bird Sentry blender. The Bird Sentry blender should be kept clean and free of dust. The exterior of the Bird Sentry blender may be cleaned with a soft cloth lightly dampened with warm soapy water or mild disinfectant. An allpurpose cleaner may be used on the exterior of the Bird Sentry blender. Store the Bird Sentry blender in a clean, dry place when not in use.
