Abstract: A ventilator delivers breathing gas to a patient via a patient circuit connecting the ventilator and the patient. The ventilator is configured to, upon activation of an oxygen boost function of the ventilator, increase the oxygen concentration of the breathing gas so as to deliver oxygen-enriched breathing gas to the patient. The ventilator includes a control unit configured to determine the volume of a part of the patient circuit conveying breathing gas from the ventilator to the patient, determine a delay in delivery of the oxygen-enriched breathing gas to the patient based on the volume, and cause indication of the delay to an operator of the ventilator.

Abstract: An improved method for the manufacture of wood fiberboard according to the wet system with a closed white water system includes the steps of drying the incoming lignocellulose containing material, prior to the dilution step, to a dryness, or solid consistency, which is higher than the dryness of the wet lap or sheet before final drying to produce the fiberboard product. Formaldehyde is added to the resulting white water which is homogenized to atomize occurring precipitations through efficient agitation and dispersion prior to being recirculated for use for diluting the incoming fiber material. Thus, there is obtained an efficient closed white water system which results in a reduction of environmentally harmful discharge of polluted water as well as the production of fiberboard with enhanced appearance.
