FIELD: medicine.SUBSTANCE: humidifying system for humidifying gas delivered to a patient comprises a source of liquid and a humidifying unit, located in patient's circuit, which provides gas to patient. Humidification unit comprises: a liquid chamber that receives liquid from liquid source wherein liquid chamber includes a concave shaped bottom portion, a nebuliser that nebulises liquid from liquid chamber, wherein nebuliser is located at bottom portion ofliquid chamber so that liquid introduced into liquid chamber is funneled towards nebuliser； an aerosol chamber that receives aerosolised particles from nebuliser； a heat source located in aerosol chamber that converts aerosolised particles into a vapour that humidifies gas in patient circuit, and a hydrophobic membrane that separates aerosol chamber from patient circuit, and wherein hydrophobic membrane prevents liquid from entering the patient circuit from aerosol chamber but permits vapour to enter patient circuit from aerosol chamber. Nebuliser comprises an aperture plate with holes, aperture plate being coupled to a vibrational element, wherein vibration of vibrational element causes aperture plate to vibrate, which causes liquid to move through aperture plate holes for nebulising fluid into aerosolised particles. Method includes steps of operating said system.EFFECT: using given group of inventions will allow to reduce power consumption, elimination of condensation or water in tubes humidifier or circuits of patient.6 cl, 4 dwgГруппа изобретений относится к медицине. Увлажнительная система для увлажнения газа, доставляемого пациенту, содержит источник жидкости и блок увлажнения, расположенный в контуре пациента, который предоставляет газ пациенту. Причем блок увлажнения содержит: камеру для жидкости, которая принимает жидкость из источника жидкости, причем камера для жидкости включает в себя нижний участок вогнутой формы； распылитель, который распыляет жидкость из камеры для жидкости, причем распылитель расп
