Multiparameter Telemetry Overview
The 90343 digital telemetry multiparameter transmitter sends NIBP data acquired
by the 90217 ambulatory blood pressure (ABP) monitor to the 90478 digital
telemetry receiver. The 90478 displays the patient’s episodic NIBP data and
trigger alarms based on thresholds set at the patient monitor. Refer to Setting Up
NIBP Monitoring on page 17-17 for information on configuring and using ABP
monitors with multiparameter telemetry.
The 90217 ABP monitor is a small, lightweight, battery-powered unit designed to
take blood pressure measurements. Refer to the 90207/90217 ABP Monitors
Operations Manual (P/N 070-0137-xx) and the 90121 ABP Report Management
System Operations Manual (P/N 070-0529-xx) for more detailed information on
this product, its initialization by a direct PC interface, patient preparation, and
event codes.
NIBP uses oscillometric monitoring to measure systolic (S), diastolic (D), and
mean (M) arterial blood pressures. The pressure readings are sent from the
90217 ABP monitor to the 90343 transmitter by a connecting cable. The 90343
transmitter includes the NIBP readings in the communications to the 90478
receiver using the radio frequency data link. NIBP measurements are checked to
eliminate the possibility of erroneous readings and valid measurements are
displayed on the monitor and stored for trending. The Ultraview monitor displays
valid measurements and the time the measurement was acquired. The most
recent reading is displayed by the Ultraview monitor. The most recent
120 readings are stored and may be displayed by the monitor.
!
• All system connections must be made by Spacelabs Medical
personnel only.
• Leakage currents are not affected by the high level output in the
90478. The patient is electrically isolated from the patient
monitor by the RF link.
• The 90217 ABP monitor is intended for use with adult patients
only and, when used with the 90343 Digital Telemetry
Transmitter, must also involve ECG monitoring.
• The ECG lead wires of the 90343 must be connected to the
patient in order to perform ECG, SpO
2
and NIBP monitoring.
• The 90217 ABP monitor, when used with the 90343 Digital
Telemetry Transmitter, purges its measurements as they are
successfully sent. This operation differs from when the 90217
ABP monitor is used in a stand-alone manner and stores a
maximum of 240 NIBP readings and event codes.
• NIBP readings which are not successfully transmitted by the
90217 to the 90478 within 24-hours of their measurement are
unavailable for display or trending.
WARNING:
• Changes or modifications not expressly approved by
Spacelabs Medical will void the user’s authority to operate
the equipment.
