This HP Vuelink M1023a Ventilator module is used with Philips IntelliVue Patient Monitors. 

The Vuelink M1023a module serves as an interface to connect external devices (such as ventilators, gas analyzers, or standalone parameter monitors) to the CMS Viridia System.

Functionality: It provides a combined RS232 (serial communication) and analog interface. This allows the module to collect information from external devices, which can then be displayed, recorded, and trended on the patient monitoring system.

The Vuelink module facilitates communication between the ventilator and the patient monitor, allowing healthcare professionals to monitor vital signs and other relevant data in real-time.

In summary, the HP Vuelink M1023a module plays a crucial role in integrating external medical devices with the patient monitoring system, enhancing patient care and safety.
