- Page 2 OVERVIEW The third generation Reduced Oxygen Breathing Device (ROBD3) is a computerized gas‐ blending instrument. The system uses Thermal Mass Flow Controllers (MFC) to mix breathing air and nitrogen to produce the sea level equivalent atmospheric oxygen contents for altitudes up to 34,000 feet. The MFCs are calibrated on flow standards traceable ...

Page 3: Rear Panel Layout
REAR PANEL LAYOUT Power input The power entry module supplies AC power to the internal power supplies. The internal power supplies convert and regulate the AC signal to the two DC voltages required by the system electronics. The power entry module has integrated EMI/RFI filtration and switch one or both hot lines dependent upon 110 or 220 VAC operation. The power entry module also has two replaceable fuses and is filtered to meet UL 544 for medical patient and non‐ patient care equipment. Gas inputs These gas inputs supply source gas to the system components. The standard fittings on these ports are ¼” NPT. The optional hoses provides quick connect fittings that are colored ... - Page 4 Vent port This port vents the excess flow of gas not used during inhalation and exhalation and also limits the pilot mask pressure. A filtered vent plug has been installed into the vent port. This vent plug will Important: provide a slight positive pressure to the breathing mask. If the absence of positive pressure is desired, remove the threaded plug. When the instrument is not being used, reinstall the plug. This vent plug should only be hand tightened. Do not install any other type of fitting into this port, as the breathing loop may become over‐pressurize and cause damage to the instrument. ROBD3 QUICK START GUIDE JANUARY 2024...

Page 5: Unpacking And Installation
UNPACKING AND INSTALLATION Transport case option W/O regulators and hoses 1. Undo all the shipping container latches and open the cover. 2. Pull the ROBD3 out by the side handles. Installation 1. Install the system on a stable table or cart. 2. Remove all obvious shipping plugs and caps from the gas ports, including the plug in the Vent port. 3. Do not remove the silver plug in the Service port. 4. Remove the protective film on the HMI touch screen controller. Power connection 1. Connect an appropriate electrical connect to the power cord provided. 2. Make sure the power switch that is integrated into the power entry module is turned off. 3. Connect the ROBD3 power input module to a 220‐240 VAC outlet. Gas Connections 1. On the rear of the ROBD2, connect the air (yellow) and nitrogen (black), at a pressure of 40 PSIG, to the respective ports. For a mask flow setting higher than 50 LPM, a pressure of up to 50 PSIG may be required. 2. Connect the 100% oxygen (green) source at a pressure of 20 PSIG. ... -
Page 6: Quick Start Procedure
QUICK START PROCEDURE Before Powering on the system make sure to perform the steps outlined in the section titled Power and gas connection. Connect the pulse oximeter probe any time before or after powering on the instrument. Power on the system. Allow the warm‐up time to elapse (10 minutes). Five beeps will be heard in succession, when warm up time has elapsed. While warm up time is counting down, flight profiles can be added or edited. (page 7) Once the warm up time has elapsed, press the function key in the option menu. SELFTST Follow the self‐test prompts carefully as errors in following the prompts will cause failures in the self‐test. After the self‐tests have run, the system will perform a self‐ calibration. The 02 sensor will calibrate and test altitudes will be performed. DANGER: During self‐tests, gas will be delivered to the mask and vent port. Do ... - Page 7 PROGRAMMING FLIGHT PROFILES 1. From the main startup screen enter the Administrator mode; per email instructions provided. 2. The setup mode will be enabled. 3. Enter the setup mode and select edit flight profile at the top of the screen. 4. The screen shown below will appear. 5. If you do not wish to change any of the flight profile names, press . NEXT 6. To change or add a flight profile name, click on the field for the respective flight profile number; see below. 7. The virtual keyboard on the next page will appear. 8.

- Page 11 PULSE OXIMETER OPERATION SpO2 and Pulse Rate Displays Like the 6202‐1 pulse ox, the ROBD3 takes about 10 seconds after placing the probe on the finger to register valid data. This is inherent to the pulse oximeter electronics/firmware. The measured SpO2 and pulse rate are displayed side by side as shown in the diagram below. The oximeter ensures that only valid pulsatile signals are processed. Bad, invalid or the absence of data causes alerts to occur and may also cause the displays to show “‐ ‐ ‐” and “‐ ‐ ‐” in the SpO2 and pulse rate displays. The displays are updated every half a second as the monitor is acquiring data. The message box, in the lower left hand corner of the display, will indicate whether or not the probe is connected to the unit or if the probe is connected to the unit, but not connected to the SUT. ...
- Page 12 Pulse Activity Bar The signal bar or pulse activity bar, on the left side, is derived from the pulsatile signal that is measured by the monitor. The height of the bar, with each pulse beat, is proportional to the strength of the signal. This pulse activity bar represents the subject’s pulse and should show regular rhythmic movement. Erratic or non‐rhythmic movement may indicate a poorly positioned or applied sensor, or may be indicative of excessive subject movement at the sensor site. SpO2 and Pulse Rate Alarms Alarm Limit Violations When the oximeter detects SpO2 or pulse rate values that exceed either the high or low limits, both an audible alarm tone and visual alarm are generated. The audible alarm volume can be adjusted, or an alarm can be muted. The visual alarms are the speaker icon ...

- Page 14 Press on one of the four blue limit buttons and a virtual numeric keypad, shown below, will appear. Enter the new value and press the enter key. This will accept the new value back into the screen below and save it indefinitely. If an alarm becomes active, access to the alarm setting screen is denied until the alarm condition clears. If an alram condition becomes active while in the alarm setting screen, the HMI will jump to the main pulse oxiemter screen. ROBD3 QUICK START GUIDE JANUARY 2024...
- Page 15 Adjusting the alarm and pulse bar volume To change the pulse bar, pulse alarm, and SpO2 alarm volumes, press Set Volume. Each time that field is pressed, the new variable to adjust will appear. Once on the desired variable, press the up or down arrow key. The value setting will flash on the screen and the beeper will beep to the new volume level. To indefinitely disable the volume for either of these setting, set the volume to zero.

- Page 16 Pulse oximeter self‐test When the ROBD3 is powered on, the classic tone sequence of the ROBD3 pulse oximeter will be heard. After the initial sound sequence, there will be a single tone, within about 8 seconds, and the screen will flash pass in the lower right hand corner. This means that the internal pulse oximeter self‐test has passed. If for some reason the internal self‐test fails to pass, the word fail will appear and remain on the screen until the self‐test passes. This will also prevent the ROBD3 self‐test from passing as well, rendering the ROBD3 inoperable. If during normal operation, the ROBD3 computer loses it communication link with the pulse oximeter and is unable to recover, the word fail will appear. ROBD3 QUICK START GUIDE JANUARY 2024...
