kPa – If the blood pressure is displayed in kPa on the screen, the blood pressure readings will be in kPa in the trend data and in the current readings of the waveform printout. Note: To set the blood pressure limits in kPa, you will need to use the Select and Set buttons on the right side of the monitor.
2.2 Monitoring SpO , Pulse Rate and the SpO Waveform The oximetry and pulse rate measurements are generally taken with the reusable fingerclip sensor (provided), however a wide variety of SpO sensors are available as accessory items. The oximetry pulse volume is displayed as a vertical bar graph, called the Plethysmograph, beside the SpO % display on the right side of the monitor.

Instrument Problem Alarms, although they rarely occur, are of three types: 1) the Atlas Monitor detected an internal fault during power-on self test; 2) the Atlas Monitor detected an internal fault during use; 3) the Atlas Monitor reports that it lost power while in use the last time it was operating. Instrument Problem Alarms do not trigger a Print On Alarm.
Battery Alarms indicate that there are 10 or fewer minutes of battery life remaining. When one minute of battery life remains, a final alarm tone indicates that the Atlas Monitor is about to shut down, and a Trend report is automatically printed. Battery Alarms do not trigger a Print On Alarm.

6.4 Connecting the Temperature Probe (Models 622xx & 623xx) The Temperature measurement comes from a skin probe. Atlas Monitor models 622xx and 623xx can measure skin temperature with the supplied surface probe. Follow the package instructions for probe placement. Fahrenheit or Celsius - Temperature is displayed in °F or °C.
6.5 Connecting the End Tidal CO Sample Tube (Model 623xx) ETCO is measured with a sample tube using a nasal cannula adapted for sidestream CO measurement. Attach the cannula to the patient’s nose. Connect the sample tube to the watertrap and plug the watertrap into the monitor.
Two menus are provided for configuring the Atlas Monitor. The items on these menus are choices that you might make to configure the Atlas Monitor to your needs when you first place it into service. You may change the date/time setting for Daylight Savings/Standard time, or when traveling across time zones.

If you have AC power available, plug in the Atlas Monitor. The battery will recharge automatically, whether the Atlas Monitor is turned on or off. The battery will return to 80% charge within 5 hours, and full charge within 24 hours. You will see the symbol lit above the ECG cable connection.
Page 98
The Atlas Monitor has detected a problem in making a Blood Pressure measurement. No internal problem is detected. Either the Atlas Monitor could not detect a pulse, could not bring the cuff to the required pressure, or detected an overpressure condition. There may also be a problem that prevented the Atlas Monitor from completing a measurement within 3 minutes of the start of the measurement.
Page 99
This reset operation has failed. RECOMMENDED ACTIONS: Turn the Atlas Monitor off and back on, and retry the CO Reset operation. Repeat several times if necessary. If repeated attempts fail, then the unit must be repaired.
Page 100
Atlas Monitor has detected a problem with the ECG leads. A signal cannot be properly detected. Note that Atlas Monitor only reports lead faults on the lead that is currently selected by the Lead Select button (and indicated in the upper right corner of the screen).

If you have AC power available, plug in the Atlas Monitor. The battery will recharge automatically, whether the Atlas Monitor is turned on or off. The battery will return to 80% charge within 5 hours, and full charge within 24 hours. You will see the symbol lit above the ECG cable connection.
Page 102
RECOMMENDED ACTIONS: If you are not above 40º C, or below 10º C, this indicates a failure or calibration error in the Atlas Monitor temperature sensing system. The unit must be repaired. MESSAGE: cable not detected MEANING: Atlas Monitor has lost communication with the SpO cable and sensor.
Page 103
RECOMMENDED ACTIONS: An electrical fault has been detected in the Temperature system. You can continue to use the Atlas Monitor until it is convenient to perform repairs, if it acceptable to operate without Temperature sensing. The unit must be repaired.
