From: High-flow nasal cannula oxygen therapy decreases postextubation neuroventilatory drive and work of breathing in patients with chronic obstructive pulmonary disease

Fig. 4

Trend of the neuroventilatory drive, as expressed by the diaphragm electrical activity peak EAdiPEAK, and of work of breathing, as expressed by the inspiratory PDI pressure-time product per breath (PTPDI/b) and per minute (PTPDI/min). *Significant difference compared to the HFNC1 period (ANOVA with Bonferroni correction); §Significant difference compared to the HFNC2 period (ANOVA with Bonferroni correction). Conventional O2 period of conventional low flow oxygen therapy through a non-occlusive face mask, HFNC1 first period of high flow nasal cannula oxygen therapy, HFNC2 second period of high flow nasal cannula oxygen therapy
