Dräger Medical has released an update to its Evita Infinity V500 ventilator that provides new functions like variable pulmonary pressure, SmartCare/PS application for better management of weaning off of the device, and a few touches to make workflow easier for clinicians. The system also uses RFID chips tagged onto breathing tubes that can transfer device settings when moving a patient from one ventilator to another.
Spontaneous breaths are subject to natural changes. The Variable Pressure Support option responds to these minute fluctuations of spontaneous breathing by varying the pressure support and thereby varying the tidal volume as well. Study data has shown that this can reduce the risk of lung damage.1 In addition to expanded therapeutic options, the software update with the Smart Pulmonary View application also offers simplified information options for the clinical staff. A lung symbol visualizes lung compliance changes and airway resistance in real-time. Once the patient is stable and requires less respiratory support, the SmartCare/ PS weaning function provides automated, knowledge-based weaning. Studies have revealed that this option makes it possible to reduce the ventilation period by up to 33 percent and the weaning time by up to 40 percent.2 The software version 2.n has specific individual weaning parameters than can be configured to make the weaning mode even more flexible to use.
However, the Evita Infinity V500 is not only a ventilator with modern therapeutic functions, but also a component of the integrated Infinity Acute Care System concept. This patient supply system optimizes clinical processes and workflows. Upon request, Dräger also provides additional components equipped with an RFID chip that are automatically detected by the device when being connected. This means the medical device is able to automate the configuration of peripherals and monitor compliance with replacement intervals. The "Transfer of Ventilation Settings" function for ventilation tubes is one innovation in the field of RFID: The RFID chip on the tube saves the ventilation parameters of a patient. When moving the tube to another suitable ventilator, the parameters can be applied without any manual reconfiguration. It is also possible to use a USB flash drive with the Evita Infinity V500 to transfer patient-related screen, therapy, and alarm settings to another intensive care ventilator of the same type.
