Birk R, et al. - This research encompassed a comparative scrutiny of the airway hydration with cold-air nebulization with heated high-flow humidification on medical interventions and tracheal ciliary beat frequency (CBF). The data displayed that the heated humidification enhanced mucociliary transport. this, in turn, led to a reduced number of required suctioning procedures in the trachea, which could improve the postoperative patient care.
