These devices significantly decrease dead space, PaCO2 and ventilator mechanical load [9] without increasing airflow resistance [31].
In conclusion, our data indicate that EIP prolongation is a simple and feasible strategy to decrease dead space and PaCO2 levels.
There is an increasing interest in extracting woody residues on clear-cuts for bioenergy production, which will further decrease dead wood amounts.
The evaluator's recommendation is displayed on the image at the level of the arrow to show the student the best place to set the depth to allow better visualization of the thyroid and decrease dead space deep to the thyroid.
De Robertis and colleagues [ 4] employed two techniques to decrease dead space: flushing the ventilator circuit and aspiration of dead space (ASPID).
In an oleic acid injury animal model, Mutch introduced fluctuations according to an algorithm, to mechanical respiration and found increased respiratory arrhythmia and oxygenation and decreased dead space compared with conventional ventilation (with similar MV) [ 48].
This result might suggest that NHF decreased dead-space ventilation.
Consequently, the ventilation/perfusion ratio decreases and dead space is reduced enabling more CO2 to be extracted by alveolar ventilation.
