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.
The monitor provides local Resp, NIBP, HR/PR and SpO
2
alarms or equipment alerts. The
following also happens:
• An alert occurs at Acuity with the message DROPOUT.
• An alert occurs at the monitor with the message Check Acuity/network connection.
• The monitor emits audible alert tones.
• The appropriate caregiver presses to acknowledge the alert.
When the monitored patient is again within range of the Acuity network, the monitor
reconnects to the network and wireless monitoring resumes.
Patient monitor behavior during operation outside of wireless network
coverage areas
When the monitor leaves a wireless coverage area, it can exhibit the following
characteristics:
• The monitor aggressively searches to locate the wireless Acuity network.
• The monitor consumes battery life at a faster rate, which reduces the battery
operating time.
• If the monitor remains out of range of the Acuity network for several minutes, the
radio enters a low-power state.
• If disconnected for longer than four hours, the monitor might generate a system fault
error that would necessitate a reset (power cycle) of the monitor.
Caution Be aware that moving the monitor out of the Acuity network range
breaks the radio link, immediately stopping communication of patient
vital-signs data.
Caution Be aware that it can take as long as three minutes to restore
communication with the Acuity network and resume the communication of
patient vital-signs data.
Note When communication with the Acuity network is re-established, the monitor
uploads trends data, but not snapshot data, to Acuity.
