Manually adjust the oxygen concentration of 0.21-0.5, flow rate 10-60:l/min, temperature 31,34, 37 ° C adjustable
Transnasal high flow humidification oxygen therapy (HFNC) is a treatment that provides controlled and relatively constant inhalation of oxygen concentration (21%~100%), temperature (31~37℃) and temperature at high flow (10~80L/min) through a high flow nasal obstruction.
High flow respiratory humidification treatment apparatus mainly includes air oxygen mixing device, humidification treatment apparatus, high flow nasal obstruction catheter and heating breathing pipeline.
All kinds of intensive care unit (ICU), emergency department, respiratory department, infection department, neurosurgery, cardiothoracic surgery, otolaryngology, anesthesiology, pediatrics, geriatrics, hyperbaric oxygen department, rehabilitation department, etc.
Clinical application of
According to the Expert Consensus on Clinical Specifications and Application of Transnasal High Flow Humidification Oxygen Therapy for Adults issued by the Respiratory Society of Chinese Medical Association
------ Chinese Journal of Tuberculosis and Respiratory Diseases, Vol. 42, No. 2, February 2019
Acute type I respiratory failure
Severe viral pneumonia, such as COVID-19 and H1N1, combined with type I respiratory failure
100 MMHG PaO2 / FiO2 or less < 300 MMHG
PaO2/FiO2 > 150 mmHg in patients with mild to moderate ARDS
Acute cardiogenic respiratory failure
Acute Ⅰ type respiratory failure was secondary to immunosuppression
Acute exacerbation of interstitial pulmonary disease
Invasive mechanical ventilation to remove the machine
ICU patients in critical condition were successively removed from the machine or alternately used with non-invasive ventilator
Patients were removed from the machine after surgery
Type II respiratory failure
Conscious patients with acute hypoxemia and hypercapnia may try it, or alternately use it with a noninvasive ventilator.
Chronic oxygen therapy in patients with stable COPD;55 mmHg < PaO2 ≤ 60 mmHg, accompanied by pulmonary hypertension, clinical manifestations of pulmonary heart disease or hematocrit >0.55);Try to use or alternate with a non-invasive respirator.
Expansion function: auxiliary endoscopy treatment, auxiliary atomization inhalation treatment
It is suitable for patients with spontaneous breathing and should not be used on life support.
