NICOLAY flow sensor two-way valve for non-invasive mechanical ventilation of premature infants
The new flow-sensor system with the NICOLAY two-way valve – to monitor the flow of what is quite possibly the patient’s most important breaths
The Solution and the Added Value
The trick to the solution was to double the number of flow sensors. Instead of one, the NICOLAY two-way valve now integrates two sensors that operate in parallel into the ventilator’s tubing system. In combination with an external signal, they make it possible to precisely determine when the small patient inhales and thus determine the essential respiratory volume with extreme accuracy. The readings from this newly designed electronic measuring system are corrected for dead space and unaffected by leakage. Thanks to the NICOLAY two-way valve, it is now possible to reliably monitor non-invasive ventilation for the first time.
