“…Warming and humidification can improve the comfort of patients with non-invasive ventilation (1). Patients undergoing nasal oxygen therapy retain the warming and humidifying function in the upper respiratory tract, however, the generation of condensed water in the pipeline can reduce patient comfort and compliance, which means respiratory humidification therapy devices are preferred in patients who use nasal high-flow humidification oxygen therapy (10)(11)(12)(13) and are mainly used in patients with acute heart failure and hypoxemic respiratory failure (14,15). In order to prevent the formation of condensed water, the pipeline and the extension pipe joints use water-permeable and airtight technology, which reduces the relative humidity of the delivered gas but improves the comfort and compliance of patients with nasal high flow oxygen therapy.…”

The present study evaluated the effect of two active warming and humidifying high-flow oxygen therapy systems in patients with tracheotomy, in order to provide a basis for selecting the method of humidification oxygen therapy for tracheotomy. A total of 78 patients with tracheotomy, who underwent surgery between July 2017 and December 2017, were randomly divided into an observation group (39 patients) and a control group (39 patients). Patients in the observation group were treated with artificial airway high-flow humidification oxygen therapy in a closed suction system. Patients in the control group were treated using a respiratory humidification therapy device. Changes of sputum viscosity, pulmonary infection, arterial oxygen partial pressure (PaO 2 ), arterial blood carbon dioxide partial pressure (PaCO 2 ) and arterial oxygen saturation (SaO 2 ) were observed at 0, 48 and 96 h, and 7 days following oxygen therapy. The sputum viscosity and lung infection in the observation group were lower than those in the control group at 48, 96 h and 7 days following oxygen therapy, and the PaO 2 and SaO 2 were higher in the observation group than in the control group, which was statistically significant (P<0.05). However, there was no statistically significant difference (P>0.05) in PaCO 2 between the two groups. In conclusion, the artificial airway high-flow humidification oxygen therapy closed suction system was considered more suitable for long-term oxygen therapy of tracheotomy patients than the respiratory humidification therapy device. It can improve airway humidification and oxygen levels at lower equipment and consumable costs. The effects of treatment aim to reduce lung infections, which have clinical implications to a certain extent.

“…HFNC oxygen therapy was an important tool to prevent respiratory failure aggravation or intubation 19 . Hughes et al published a retrospective study showing that, in the Emergency Department, HFNC oxygen therapy successfully reduced arterials levels of CO2 in hypercapnic patients without reducing the arterial oxygen levels 20 .…”

High flow nasal cannula (HFNC) oxygen therapy devices are used on a daily-basis in many intensive care units and postoperative wards. Such a device deliver a mixture of air and oxygen, warmed, humidifi ed, with gas flow between 20-60 L/min, and inspired oxygen fraction between 0.21-1. Therefore, it improves oxygenation, decreases dead space, washes out the carbon dioxide (CO2) from patients' airways, improves thoraco-abdominal synchrony and decreases the work of breathing. Studies have shown effi cacy of HFNC oxygen therapy use for acute hypoxemic respiratory failure, for patients with exacerbations of chronic pulmonary diseases, after extubation in order reduce the need for mechanical ventilation, in perioperative period to prevent atelectasis and in palliative care, in order to reduce breathlessness. It isn`t feasible for patients with severe altered neurological status, facial trauma, basal skull fracture, complete airway obstruction or epistaxis. There are no standardized recommendation for the use or contraindication of HFCN oxygen therapy. The weaning is realised according with patients' tolerance, oxygen saturation, respiratory and heart rates.
