High Flow Nasal Oxygen Therapy in Perioperative Period of the Adult With Hypercapnic and Hypoxemic Respiratory Faliure

The purpose of this study is to determine the impact of hign-flow nasal therapy on the adult with hypercapnia and hpoxemia respiratory faliure in comparison with standard oxygen therapy ang noninvasive ventilation.

Study Overview

Detailed Description

Humidified high flow nasal oxygen therapy decreases dilution of the inhaled oxygen and, by matching patient's peak flow, allows accurate delivery of the set FiO2 throughout the whole inspiratory phase.The purpose of this study is to determine the impact of hign-flow nasal therapy on adult hypercapnic respiratory failure by comparing with nasal continuous positive airway pressure

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: standard low flow therapy
In the standard low flow therapy is applied continuously through a nonrebreather face mask at a flow rate of 10 liters per minute or more. The rate was adjusted to maintain an oxygen saturation level of 92% or more.
In the standard low flow therapy oxygen group, oxygen at a flow rate of 10 liters per minute or more.
Experimental: high flow nasal oxygen therapy
In the high-flow-oxygen group is passed through a heated humidifier and applied continuously through large-bore binasal prongs, with a gas flow rate of 30-60 liters per minute . The fraction of oxygen in the gas flowing in the system was subsequently adjusted to maintain an Spo2 of 92% or more.
The patient will receive high flow nasal of humidified oxygen, set between 30 to 60 l/min. The inspired fraction of oxygen (FiO2) will be adjusted in order to obtain a SpO2 >92%.
Placebo Comparator: Noninvasive ventilation
In the noninvasive-ventilation group is delivered to the patient through a face mask that was connected to an ICU ventilator,with pressure support applied in a noninvasive ventilation mode. The Fio2 or PEEP level (or both) were then adjusted to maintain an Spo2 of 92% or more.
The patient will receive successively in a day NPPV and O2-HFN. The NPPV will be applied with an airway humidification achieved by using a heated humidifier and a facial mask adapted to the morphology of the patient. The settings will be adjusted as follow : an inspiratory pressure between 6 to 14 cmH2O, in order to obtain a tidal volume between 7 to 10 ml/kg of predicted weight, a positive expiratory pressure between 0 to 10 cmH2O in order to obtain a SpO2 >92% with the minimal FiO2.
