The routine application of weaning protocols has been unsuccessful for practical reasons so far. The process takes a lot of time, a multitude of parameters must be recorded, and the final assessment of the results remains difficult. The new intensive care ventilator elisa 800 puts weaning on a solid footing. The device combines patient results from structured clinical analysis with real-time data, allowing for the reliable and simple performance of daily weaning protocols and their dependable assessment. The Weaninganalyzer™ accurately determines a patient's status in the weaning process and generates a dependable prognosis for their readiness for extubation as the best prevention of complications caused by unnecessary long stays on the ventilator.
