Key result
Daily biofeedback significantly reduced mean ventilator days compared to control (20.6 vs 32.6 days; P<0.01) in hard-to-wean patients.

Supports biofeedback in weaning protocols for hard-to-wean patients; extends RCT evidence for adjunctive respiratory training.
Holliday et al. (1990) conducted an RCT in Hard-to-wean from mechanical ventilation (n=40). Biofeedback (frontalis EMG relaxation, VT/DAP, and VT feedback) vs. Control (daily visits for attention and reassurance) was evaluated on Mean ventilator days (p=<0.01). Daily biofeedback significantly reduced mean ventilator days compared to control (20.6 vs 32.6 days; P<0.01) in hard-to-wean patients.
