  • Page 7: Overview

    OVERVIEW OVERVIEW The second generation Reduced Oxygen Breathing Device (ROBD2) 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 40,000 feet. The MFCs are calibrated on primary flow standards traceable to the National Institute of Standards and Technology (NIST).

  • Page 11 SYSTEM 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 five 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.
  • Page 12 SYSTEM LAYOUT Vent port This port vents the excess flow of gas not used during inhalation and exhalation and also limits the pilot mask pressure. Important: A filtered vent plug has been installed into the vent port. This vent plug will provide a slight positive pressure to the breathing mask. If the absence of positive pressure is desired, remove the threaded plug.

  • Page 13: Unpacking And Installation

    UNPACKING AND INSTALLATION UNPACKING AND INSTALLATION Standard packaging and unpacking 1. Remove the system from the cardboard box in which it was delivered from the factory. 2. Remove and read any important instructions or notes found within the box. 3. Save and store the box and foam inserts in the event the system needs to be returned to the factory or delivered to another site for operation.

  • Page 14: Power And Gas Connections

    POWER AND GAS CONNECTIONS After the RODB2 is unpacked, the system should be connected to power and the appropriate gas sources to the gas inlet ports on the rear panel. Environics recommends the use of a power conditioner, as recommended for computers, to eliminate power problems from affecting system operation.

  • Page 15: Gas Connection

    POWER AND GAS CONNECTIONS Gas Connection Input Gas Connections Input Gas connections are keyed and colored quick connect fittings. 1. On the rear of the ROBD2, connect the air (yellow) and nitrogen (black), at a pressure of 40 to 50 PSIG, to the respective ports. Connect the 100% oxygen (green) source at a pressure of 20 PSIG.

  • Page 16: Quick Start Procedure

    QUICK START PROCEDURE QUICK START PROCEDURE 1. Before Powering on the system make sure to perform the steps outlined in the section titled Power and gas connection. 2. Connect the pulse oximeter probe any time before or after powering on the instrument.

  • Page 17: Power Up And Self-Tests

    POWER UP AND SELF-TESTS POWER UP AND SELF-TESTS Power up The system power switch is on the rear panel power entry module. It is important that all gas connections are made before self-tests. Refer to the section titled Gas connection. Warmup The system requires a 10 minute warmup period after it is powered up.

  • Page 18: Self-Test Operations

    POWER UP AND SELF-TESTS Self-test Operations Oxygen sensor test The oxygen sensor test will check the on-board oxygen sensor accuracy. The system will provide air to the sensor for 20 seconds and report the 02 content as read by the un-calibrated 02 sensor. If the 02 content falls outside the limits set by the test, the test will fail.

  • Page 19: Self Calibration Operations

    POWER UP AND SELF-TESTS Self-Calibration Operations Before running programs, the system must run through its self-calibration routine at the start of each operating day, and every time the system is powered on. These tests will run automatically after the system has warmed up for 10 minutes. If this process is not run, the system will not allow the operator to enter the START mode.
  • Page 20 POWER UP AND SELF-TESTS Once the system has calibrated the sensor for air, it will proceed to supplying 100% 02 to the sensor. The following will be displayed: ANALYZING 100% 02 ACTUAL 02 PERCENT 02 SENSOR CAL REMAINING TIME AS READ BY 02 MEASURING 02 100% SENSOR 02= 99.5%...

  • Page 29 YES to rerun the test, otherwise press NO. ROBD FLOW RATE The flow rate of the 6202-1 is adjustable from 40 LPM to 80 LPM. The nominal setting is 50 LPM to provide enough gas flow to the subject under test while preserving valuable gas.
  • Page 30 SYSTEM OPERATION ADMIN MODE The ADMINinstrator MODE allows access to Administrator level functions, which include programming of test routines (PROG mode) and system functions (SYSTEM mode) such as MFC calibration. To enter ADMIN mode, select ADMIN MODE from the menu and press ENTER. If there is an Administrator password, you will be prompted to enter it.
  • Page 31 SYSTEM OPERATION ADJUST CONTRAST The contrast of the LCD display is affected somewhat by the angle at which the display is viewed as well as the ambient temperature. To adjust the contrast for optimum results: 1. Using the up and down arrow keys, move the pointer cursor down to the line that reads ADJUST CONTRAST and press the ENTER key.

  • Page 32: Safety Features

    SAFETY FEATURES SAFETY FEATURES There are a number of built-in safety features to either alert the operator or stop the operation of the system and go to a “safe” mode of operation. Oxygen dump switch An emergency Oxygen Dump switch has been provided to supply 100% oxygen on demand as the subject under test (SUT) becomes hypoxic.
  • Page 33 SAFETY FEATURES If Low O2 Pressure is detected in the Ready mode, the system will display LOW O2 instead of READY, on the screen In the Pilot Test Menu, if any of the Pilot Test keys (RUNPRG or PPT) are pressed during a Low O2 Pressure condition, the system will display the following screen and prevent the system from running in the Pilot Test Menu.

  • Page 34: Pulse Oximeter

    PULSE OXIMETER PULSE OXIMETER SpO2 and Pulse Rate Displays Like the 6202 pulse ox, the 6202-1 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.

  • Page 35: Spo2 And Pulse Rate Alarms

    PULSE OXIMETER 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.
  • Page 36 PULSE OXIMETER Setting SpO and pulse rate alarm limits To access the alarm setting screen, press the pulse or SpO2 display windows shown below. For touchscreen variables either a finger or stylus can be used. ROBD2 USER’S GUIDE SEPTEMBER 2016...
  • Page 37 PULSE OXIMETER 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.
  • Page 38 PULSE OXIMETER 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.
  • Page 39 PULSE OXIMETER Pulse oximeter self-test When the 6202-1 is powered on, the classic tone sequence of the 6202 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.
