The study includes the comparison of the three methods of non-invasive ventilation: non-invasive mask ventilation, high-flow oxygen therapy through a nasal cannula (high-flow nasal oxygenation) and non-invasive ventilation with a helmet in patients with mild and moderate respiratory failure in the early postoperative period after cardiac surgery. It assumes 90 randomized patients:30 patients in three study groups male and female aged 30 to 60 years of age inclusive, with mild or moderate respiratory failure.The study will be randomized, single-center, prospective.
