Page 10: General Description
General Description The Model 9843 Pulse Oximeter and Carbon Dioxide Detector is a hand- held, battery-operated, noninvasive monitoring device that has visible and audible indicators for tracking patient status. The Model 9843 typically will operate for 90 hours continuously between battery replacements when used for pulse oximetry alone, or for 20 hours continuously when used for both detection and pulse oximetry. -
Page 11: Pulse Oximeter
Pulse Oximeter The Model 9843 determines functional oxygen saturation of arterial hemoglobin (SpO ) by measuring the absorption of red and infrared light passed through perfused tissue. Changes in absorption caused by pulsation of blood in the vascular bed are used to determine arterial saturation and pulse rate. - Page 12 Unpacking Your Model 9843 Contact the carrier immediately if the shipping carton for the Model 9843 is damaged. Carefully unpack the instrument and its accessories. Confirm that the items listed below are packed with the Model 9843 Pulse Oximeter and Carbon Dioxide Detector.

Page 13: Basic Operation
The Model 9843 Pulse Oximeter and Carbon Dioxide Detector is powered by six AA size alkaline batteries that will typically provide 20 to 90 hours of continuous operation, depending on how the 9843 is used. The 9843 will typically operate for 90 hours continuously between... - Page 14 Replacing Batteries in the Model 9843: Remove the battery door on the bottom of the 9843. Remove all six used batteries. If necessary, gently tap the device against the palm of your hand to dislodge all of the batteries. Replace all six used batteries with fresh AA size batteries. Be sure to use the correct battery orientation when installing the new batteries.
- Page 15 Pulse Oximeter Sensor Connect the pulse oximeter sensor (with the NONIN logo facing up) to the top of the 9843 as shown in Figure 5. Ensure that an appropriate sensor is firmly plugged in, and position the sensor on the patient.

Page 16: Power On Self-Test
Power On Self-Test When the 9843 is turned on for normal operation, it cycles through a self-test before displaying valid data. When entering setup mode at power on, the 9843 cycles through the same self-test routine. Verify that all audible and visible indications are operating properly during the power on self-test. - Page 17 Verify that the airway adapter tube is properly attached to the CO sensor and that the CO sensor is properly connected to the 9843. Next, verify that the lower bar of the CO display is illuminated and the lamp inside the CO sensor is flashing on and off.

Page 18: Cleaning The Model
Clean the 9843 (device only) with a soft cloth dampened with ä isopropyl alcohol. Do not pour or spray any liquids onto the 9843, and do not allow any liquid to enter any openings in the device. Allow the 9843 to dry thoroughly before reusing. -
Page 19: Detailed Operation

Continue this process until all parameters are set. When the setting sequence has been completed, the 9843 exits the setup mode and begins normal operation. The settings can be easily checked, since the first value displayed for each parameter represents the current setting.
- Page 21 Calendar Settings NOTE: Setting the month to “00” disables the calendar and clock functions and helps conserve battery life. The calendar and clock functions are used to time stamp real-time data for printing or memory. Unless you intend to use real-time data output or memory playback options, skip this section.

When the batteries reach a critically low level, the low battery indicator flashes and no patient data is displayed. The batteries must be replaced before using the 9843. If the batteries are critically low at power on, setup mode will be disabled and the displays will be blank. - Page 25 Δ Display ( The CO display will remain blank until the sensor is plugged in. When an airway adapter tube is connected to the CO sensor and an adequate signal is detected, the bottom bar is initially illuminated. Additional bars will be illuminated to indicate an increase in CO level as the patient exhales through the airway Bottom...
