Introduction Cardiac Output (CO) (Optional)
18 - 2 V Series Operating Instructions
18.1 Introduction
This chapter describes the CO parameter in detail, including describing how to configure CO alarm 
limits, monitor CO, and configure the CO parameter settings (for example, height, weight and auto 
start).
Cardiac Output (CO) is the amount of blood ejected from the left ventricle each minute, expressed in 
liters per minute (l/min). Cardiac Index (CI) is the Cardiac Output divided by the patient's body surface 
area. 
Patient Sizes
Intended patient types: Adult and Pediatric. The CO module is not available for Neonate patients. 
CO Module Connector
The VPS module does not include the CO parameter. The CO parameter is available as a separate 
module (as shown in FIGURE 18-1). Refer to "Taking CO Measurements" on page 18-6 for additional 
information.

Button on CO Module
The CO module has one (1)   button. Press the Start CO button to enable the monitor to take the 
CO measurement when Auto Start is disabled.

Options Dialog" on page 3-2 for additional information.
