Abstract

NEIVA, Sandrine et al. HIGH-FLOW OXYGEN THERAPY FOR VENTILATOR WEANING OF TRACHEOSTOMIZED PATIENTS: SCOPING REVIEW. RPER [online]. 2021, vol.4, n.1, pp.64-72.  Epub June 30, 2021. ISSN 2184-965X.  https://doi.org/10.33194/rper.2021.v4.n1.172.

Introduction:

Prolonged invasive mechanical ventilation is costly and has associated complications. Successful early ventilatory weaning is increasingly important, and the aim of this study is to describe the evidence about the use of High Flow Oxygen Therapy by Tracheostomy in this process.

Methodology:

Scoping Review according to the Joanna Briggs Institute® methodology, with research carried out in the following databases: CINHAL, PubMed and LILACS.

Results:

Four studies were included: one case study and three randomized controlled studies. Regarding the protocols used in the implementation of high flow oxygen therapy by tracheostomy, they varied between different flows, time of use and combination with other ventilation modes. The main parameters monitored were: respiratory rate, FiO2, SpO2, PaO2, PaCO2 and the PaO2 / FiO2 ratio.

Discussion:

The use of high flow oxygen therapy by tracheostomy has advantages over the use of other ventilation modes during the weaning process. This strategy has an impact on the improvement of the monitored parameters and on the decrease in the time of ventilatory weaning.

Conclusion:

The main contributions of high-flow oxygen therapy through tracheostomy in ventilatory weaning are: improved oxygenation, decreased respiratory effort, increased tidal volume, decreased weaning time and improved airway cleaning efficiency.
