When activating the speaking valve function, the ventilator knows there is no flow back into the system and automatically deactivates certain alarms and disables certain modes.
This increase safety by restoring the correct alarm settings once speaking valve is deactivated, reduces nuisance alarms and other effects caused by the negation of the ability to measure expiratory flow and volume.
This is another example of functions incorporated in the Panther ventilators to streamline operations and reduce possible introduced risks due to required clinician adjustments.
