ABSTRACT

Objective To explore the clinical value of humidified high flow nasal cannula oxygen therapy (HHFNC) oxygen therapy for acute hypoxic respiratory failure.Methods Totally 37 patients with acute hypoxic respiratory failure were enrolled who entered ICU from January 2016 to June 2016 and randomly divided into FM group (n=l8) and HHFNC group (n=19).The values of blood gas analysis were recorded as before treatment,1 h and 5 h after therapy,respectively.Results 1 h and 5 h after therapy,both groups had significant increase in pa(O2) compared to before treatment (P＜0.05).Meanwhile,HHFNC group had higher level ofpa(O2) in comparison to FM group (P＜0.05).Conclusion HHFNC oxygen therapy has a therapeutic effect on acute hypoxic respiratory failure which helps to correct hypoxemia and improve subject feeling of comfort.
