Q Plus | CCO/SvO Computer

The Q2 Plus Computer

  • Large, color-coded screen information allows clear communication of data, while large input keys provide convenient inputting of information.

  • Faster response to changes in cardiac output,2 especially under conditions of high thermal noise, results in more timely and accurate CO information.

  • Exclusive 3-wavelength technology provides more accurate SvO2 measurements independent of varying hemoglobin levels, eliminating the need for clinical updates of hemoglobin/hematocrit values.1

  • User-selected signal processing modes allow you to configure the system to meet specific needs. All four modes are designed for reliable, accurate CCO measurements by offering different levels of thermal noise artifact rejection and response time.

  • Exclusive Quality Signal Indicator (QSI) communicates, at a glance, how robust the CCO output is in relation to thermal background noise, providing an indication of the signal's quality.


How it works

Interactive Menus

Standard interactive screens have blue backgrounds. They display the Q2 Plus main menu and most of the subsequent interactive screens, and provide option choices or fields for entering information.

Custom Display Configuration

Data screens have black backgrounds with color-coded information: SO2 values are displayed in yellow and CCO/CCI values in green. Depending on your specific needs, they can contain a wide range of numeric and trend data, including concurrent patient information.

Light Intensity Baseline

Obtaining a light intensity baseline is facilitated by the screen design. The screen shows the current light intensity; optimal, acceptable, and unacceptable examples of light intensity readings; and a baseline checklist. Once performed, the current light intensity will always be prominently displayed on the screen.
