Fig. 2. Change in dyspnea scores with high flow oxygen and BiPAP.

Fig. 2

As compared with baseline, BiPAP was associated with an average improvement in (A) the dyspnea numeric rating scale of 3.2 (P=0.004) and (B) the modified Borg scale of 1.5 (P=0.13). High flow oxygen was also associated with an average improvement in (C) the numeric rating scale of 1.9 (P=0.02) and (D) the modified Borg scale of 2.1 (P=0.007). Intention-to-treat analysis revealed no significant differences between the two devices with the dyspnea numeric rating scale (P=0.32) and the modified Borg scale (P=0.29).
