60 Standalone monitoring Welch Allyn Propaq LT Vital Signs Monitor Monitoring SpO2 The monitor can be purchased with the Nellcor or the Masimo SpO2 option. Most of this chapter pertains to either configuration. Monitors with the Masimo technology, however, can provide additional SpO2 data. (“About the Masimo SpO2 display” on page 64.) WARNING Accurate measurements of oxygen saturation, when derived from pulse oximetry, depend to a great extent on patient condition and proper sensor placement.
Directions for Use Standalone monitoring 61 WARNING Interfering substances: Carboxyhemoglobin can erroneously increase readings; the level of increase is approximately equal to the amount of carboxyhemoglobin present. Methemoglobin and other dysfunctional hemoglobins can also cause erroneous readings. Further assessment beyond pulse oximetry is recommended. Intravascular dyes, or any substances containing dyes, that change usual arterial pigmentation can cause erroneous readings.

73 4 Monitoring in communication with Acuity About wireless monitoring The model 802LTAN, 802LTAS, 802LTRN and 802LTRS wireless monitors can operate either in standalone mode or in communication with a Welch Allyn Acuity Central Station. (See “Standalone monitoring” on page 47.) While the wireless monitor is connected to the FlexNet network, patient data gathered by the monitor is continuously stored at Acuity.
74 Monitoring in communication with Acuity Note Welch Allyn Propaq LT Vital Signs Monitor When the monitor is used in Canada: To provide maximum shielding (to prevent radio interference to the licensed service), the monitor is intended to be operated indoors and away from windows. Radio equipment (or its transmit antenna) that is installed outdoors is subject to licensing.
Directions for Use Monitoring in communication with Acuity 75 Monitoring a patient outside of network range Monitors are typically deployed in an active wireless network environment where devices continually communicate with a central station. These monitors occasionally leave the wireless coverage area during transport to a procedure room (for example, a trip to X-ray). When a monitor goes outside of the network range, monitoring continues locally.
76 Monitoring in communication with Acuity Welch Allyn Propaq LT Vital Signs Monitor Caution Do not leave a wireless monitor that is turned on outside of its wireless communication area for more than four hours. If your facility has unusual clinical workflows that require wireless devices to be off of the network for extended periods, do one or more of the following: • Extend the wireless coverage area to include areas where devices stay for longer periods of time.

When the monitor re-establishes communication with Acuity (after an interruption of at least 30 seconds), it prompts you to confirm that the patient being monitored is the same patient that was being monitored when communication was interrupted. Figure 82.
Directions for Use Monitoring in communication with Acuity 79 To disconnect from the network Disconnecting the monitor from the network while the monitor is outside of network range greatly extends battery life. However, connection with the network must first have been established before this is possible. Note 1. Highlight and press . 2. Highlight Disconnect, press , and confirm. Figure 84.

81 5 Alarms and alerts Overview An Alarm warns of a patient condition, such as a vital-sign reading that is outside of acceptable limits. When an alarm occurs, the red light on the monitor flashes and the numerics of the violating alarm limits on the display turn red. If tones are not suspended, the alarm tone sounds. An Alert warns of an equipment condition, such as a low battery or a detached lead.

103 8 Monitor configuration Overview The monitor can be configured in various ways. Each facility can define as many default configurations as required to both meet the needs of individual departments and units and to conform to the facility’s general methods and standards. • Each time the patient mode is changed, the monitor settings return to the default configuration settings for that patient mode.
104 Monitor configuration Welch Allyn Propaq LT Vital Signs Monitor When a custom configuration is downloaded to the monitor, the settings and behaviors defined in the custom configuration become the power-up defaults for the monitor, and the factory configuration is no longer in effect. However, the factory configuration information can always be restored by qualified service personnel and can also be restored by downloading the configuration file PropaqLTFactoryConfig.mnt from a PC to the monitor.
