High-flow Tracheal Oxygenation: A New Tool for Difficult Weaning

Lakshman Ramachandran et al. Indian J Crit Care Med. 2021 Feb.

Abstract

High-flow tracheal oxygenation (HFTO), a modification of high-flow nasal cannula (HFNC), has been used in tracheostomized patients but only rarely for weaning. We present two cases on prolonged mechanical ventilation (PMV) where HFTO assisted weaning.

Weaning protocol used for case 1 (A) and case 2 (B). Note: On Day 15, case 2 was directly put on HFNC without any T-piece trial. Lower panel illustrates the changes in the respiratory parameters (on left axis) of case 1 (C) and case 2 (D) while on HFTO. Note the significant improvement in P/F ratios (purple lines on left axis) in both cases as the durations of HFTO (Blue plots on right axis) increases till full-time HFTO ventilation is reached
