[Clinical application of the forced oscillation technique for titration of pressure support levels in chronic obstructive pulmonary disease patients during nasal noninvasive positive pressure ventilation].
To study the use of oscillatory resistance (Rrs) and reactance (Xrs) to guide the settings of pressure level of ventilators in patients with severe chronic obstructive pulmonary disease (COPD) during noninvasive positive pressure ventilation (NPPV). ⋯ Although slightly underestimated, R(rs, in) is helpful to guide the settings of inspiratory positive airway pressure level, which will appropriately overcome the elevated pulmonary resistance, and the threshold value of deltaXrs, of end-expiratory pressure, which will eliminate the majority of EFL breathing cycles.
