    Hi All,

    My first time posting here. I am new to the medical industry and device regulations. I would like to know the requirement for a patient monitor LCD brightness. I have tried finding this information in numerous 60601 standards documents but was unsuccessful. Perhaps this is an easy question for those with more experience and knowledge.

    I am looking for something like "vital information should be visible from x meters, within y degrees/angle under an ambient lighting of z lux"

    Would anyone be able to clarify, or point me in the right direction (or document)? Thanks in Advance.

    SZ

    As far as I know, there are no specific requirement and determination is left to you. ANSI/AAMI HE75 touches on these questions but pretty much defers to your usability study to drive the specifications.

    Would an Occupational Therapist be able to help you out...someone who could understand how devices are positioned and includes the needs of the patient/user?

    Thanks for the replies everyone. I believe I have found an answer by research. This information relates more to the regulation of Alarm signals than it does to display brightness of the monitoring device. Yodon may be correct that there are no specific brightness requirements laid out for displays. However, 60601-1-8 section 6.3.2 details requirements for visual alarm signals - Since these signals are shown on the display device, these requirements extend to your display device.
