The anode humidification has more significant influences on the cell performance than the cathode humidification, and the best performance occurs at moderate air relative humidity while the hydrogen is fully humidified.
In terms of flow rate, when slow flows are delivered, there is more time for gas humidification.
This effect is more pronounced in rooms where the humidification is located.
Until the development of modern devices, the provision of nasal cannula gas at a flow rate of more than about 2 l/min and the humidification of the air were not recommended in newborns [ 21].
In addition, fluorescent signal strength of OH radicals pronounced weakening, the flame gradually appeared W type distribution and more and more obvious with the increased of humidification amount.
Conditions of low humidity lead to drying of the mouth and throat [54] and increased salivation potential from more highly branched glands could aid in maintaining humidification and protection from infection in dry conditions.
Although nebulization by itself exerts some form of humidification, caution should be taken when nebulization lasts more than 1 h to avoid damage to the ciliated epithelium and endotracheal tube occlusion [24].
The more elaborate versions of this instrument are equipped with heating elements and humidification systems beneath the perforated table surface.
These alterations could be compensated for by increasing the humidification rate (Table 3) of the additional humidification system, which differed more than 50% from patient to patient.
