12 Introduction Welch Allyn Propaq LT Vital Signs Monitor
HIPAA Considerations
Each medical facility is responsible for creating and enforcing policies and procedures to 
guarantee compliance with the regulations defined in 45 CFR 160-164 of the Health 
Insurance Portability and Accountability Act (HIPAA) of 1996.
The Propaq LT Monitor, the Large Color Display Interface, the Propaq LT Monitor 
Configuration Utility, and the Propaq LT Monitor AutoPrint Utility incorporate security 
features that support your implementation of the HIPAA requirements for ensuring that 
patient information is kept private and confidential.
Monitor
• Clinicians can lock the monitor display to prevent the display of patient vital signs. For 
patient protection when the monitor display is locked, the display is restored instantly 
in the event of a button press (unless button-pad lock-out is enabled), an alarm or an 
alert.
• Clinicians can lock the monitor buttons to prevent any unauthorized access to the 
monitor controls. To protect the patient when the buttons are locked, access to the 
buttons is restored instantly in the event of an alarm or an alert.
• All patient data transmitted by radio from the monitor is fully encrypted. This data can 
be decrypted only by a Welch Allyn Acuity Central Station residing on the local Welch 
Allyn FlexNet network. Transmitted patient data is sent via the 802.11 
spread-spectrum, frequency-hopping protocol, using the Welch Allyn proprietary PSI 
communications protocol. 
Configuration Utility
The configuration utility never contains patient data.
AutoPrint Utility
• All patient data is stored in a Welch Allyn proprietary data format which is readable 
only by machine.
• All patient data is deleted from the PC when it is sent to the printer.
