I can say unequivocally, that I'm astonished at the efficiency of this unit's ability to heat and humidify even at flow rates and minute volumes
stated in the unit's specifications.
5 mmHg and the minute volume
measurement by the ventilator software has an error margin of [+ or -] 8%.
As the patient's spontaneous efforts and respiratory mechanics (compliance, resistance) improved, the percentage of target minute volume
was gradually manually reduced to a minimum of 60%.
This is because the content of the reservoir tube depends on a balance between the supplementary gas flow entering the reservoir and the patient's minute volume
leaving the reservoir (Figure 6).
The minute volume
can be decreased by lowering the pressure support level, tidal volume, respiratory rate, or by increasing TE.
The subminiature electronic valves offer a fast response time for accurate dosing of minute volumes
To overcome this problem, the Freiburg-based research group has developed a microfluidic chip that works with minute volumes
of liquid: the platform uses microchannels to feed cell cultures with nutrients during their three-week growth period.
