Bird Sentry™ Blender Read this entire manual before attempting to operate or service the Bird Sentry™ blender: Attempting to operate the Bird Sentry blender without fully understanding its features and functions may result in unsafe operating conditions. Read the Safety Information section. It lists warnings, cautions, and notes pertinent to the safe servicing of the Bird Sentry blender. -
Page 7: Safety Information
The following warnings apply any time you operate or service the Bird Sentry blender: ● To avoid explosion, do not operate the Bird Sentry blender in the presence of flammable anesthetics or in an atmosphere of explosive gases. Operating the Bird Sentry blender in flammable or explosive atmospheres may result in fire or explosion. - Page 8 CareFusion specified lubricants when servicing the Bird Sentry blender. ● As long as the total pressure of the gas mixture being monitored is constant, the Bird Sentry blender will accurately read oxygen concentrations. However, if the total pressure varies the reading will fluctuate proportionately as the sensor actually measures the partial pressure of oxygen in the mixture.

Page 13: Chapter 1: Introduction
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. -
Page 14: Front Panel Functional Description
This key is used to turn on or off. The blender will continue to function and deliver mixed gas with display turned to OFF. When the ON/OFF key is pressed once, the Bird Sentry blender will start to display the oxygen concentration and the keypad is activated. If the ON/OFF key is pressed again, the Bird Sentry blender reverts to the display power off mode. - Page 15 UP and DOWN arrow keys. When the low alarm value is set and the LOW SET or LOCK key is pressed again, the Bird Sentry blender exits the alarm set mode and returns to normal operation. The Bird Sentry blender will also revert to normal operation (storing the most recent alarm value) if 10 seconds elapse and no keys are pressed.

Outlet Port A diameter indexed (DISS) oxygen fitting that, when connected with a pneumatic metering device (such as a flow meter or ventilator), delivers flows from the Bird Sentry blender from 2–100 LPM. Medical Air Inlet Connector A diameter indexed (DISS) air fitting for connection to an air-inlet hose from the air-gas source. -

Bird Sentry™ Blender Chapter 1: Introduction Outlet Port See Figure 1, letter O. 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. -
Page 18: What You Will Need To Operate The Blender
Do not operate the blender unless qualified personnel are in attendance to promptly respond to alarms, inoperative conditions, or sudden malfunctions. How to Get Help If you have a question regarding the installation, setup, operation, or maintenance of the Bird Sentry blender, contact customer service at the following numbers: Technical support: Hours: 7:00 a.m. -
Page 19: Chapter 2: Operating Procedures
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. -
Page 20: Basic Operation
To check the oxygen concentration of a sample gas: Place the sensor probe in the sensor port on the Bird Sentry blender. If using a standard T adapter in an alternate location, make sure the sensor is mounted in the adapter with the flow diverter pointing downward. -
Page 21: Calibration Procedures
It is best to calibrate the Bird Sentry blender using the sensor port, and with a technical grade oxygen standard (99.996% or better) at a pressure and flow similar to your application. Calibration of the unit at lower concentrations or with room air is less desirable. -
Page 22: Automatic Calibration To Known Concentration
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: Place the external probe in room air. -
