[The clinical application of bi-level positive airway pressure noninvasive ventilator for home mechanical ventilation via tracheostomy in patients with amyotrophic lateral sclerosis].
To study the feasibility of the bi-level positive airway pressure (BiPAP) non-invasive ventilator used in home mechanical ventilation for long-term tracheostomy-mechanical ventilation (TMV) in patients with amyotrophic lateral sclerosis (ALS). ⋯ For ALS patients who need long-term ventilation support, the use of BiPAP non-invasive ventilators is a safe and effective alternative for invasive ventilators.

[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.

[Impulse oscillometry for estimation of airway obstruction].
To explore the application of impulse oscillometry (IOS) in the estimation of airway obstruction and to evaluate the correlation between spirometry indices and IOS parameters. ⋯ IOS parameters can be used to evaluate airway obstruction. Among IOS parameters, R(5) was the most sensitive, which was also significantly correlated with spirometric parameters.

Controlled Clinical Trial[Association between residual sleepiness and central sleep apnea events in patients with obstructive sleep apnea syndrome].
To investigate the possible association between residual sleepiness (RS) and central sleep apnea events in patients with obstructive sleep apnea syndrome (OSAS) following continuous positive airway pressure (CPAP) treatment, as well as the effects of adaptive servo-ventilation (ASV) on RS. ⋯ RS in OSAS patients following CPAP treatment was associated with their CSAI before and during treatment. By effectively eliminating CSA events with ASV, RS was significantly improved, which suggested that ASV was effective in treatment of RS. The elevation of plasma TNF-alpha level was correlated with the severity of sleepiness and may be involved in the pathogenesis of RS.
