Page 11: Section 1 - Introduction
Section 1 — Introduction Description The 506DN patient monitor is a compact vital signs monitor that measures heart rate, blood oxygen saturation (SpO ) and non- invasive blood pressure (NIBP). Heart rate is measured primarily by the plethysmographic waveform but when the oximeter is not is use, heart rate is determined from the blood pressure data using an oscillometric method that measures during inflation.
Page 12: Non-Invasive Blood Pressure (Nibp)
Section 1 —Introduction Non-Invasive Blood ® The 506DN monitor uses ComfortCuff technology to determine non-invasive blood pressure by means of oscillometry. The Pressure (NIBP) oscillometric method detects volume displacements within the artery and senses pressure variations within the blood pressure cuff during inflation.
Page 13: Nibp Clinical Testing And Accuracy
Section 1 —Introduction NIBP Clinical Testing This device was clinically tested per the requirements of EN 1060 and AAMI SP-10. The NIBP module as installed in the 506DN patient and Accuracy monitor has been tested to meet the performance specifications listed in this manual.
Page 14: Heart Rate
The monitor continues to look for valid SpO based heart rate measurements and attempts a second NIBP measurement if the first attempt fails. Page 1-4 Service Manual Criticare Systems, Inc. eQuality™ 506DN...

Page 45: Section 3 - Theory Of Operation
Section 3 — Theory of Operation System Architecture The 506DN monitor’s circuitry consists of a Main Board, LCD Module, Module, and NIBP Module. The Main Board, SpO Module and NIBP Module are considered the Main Module. This module is located in the monitor’s font bezel. The LCD display mounts to the main board, which in turn mounts to the front bezel.
Page 46: Module Architecture
Section 3 —Theory of Operation Module Architecture Main Board The hardware design of the 506DN monitor relies on multiple serial communication channels wherein the Main Board functions (pn 91410A001) as the hub. Signal and display processing is off-loaded to the various vital signs technology modules, the Display Board, and the LCD Module.
