Potential neuroprotective effects of acupuncture stimulation on diabetes mellitus in a global ischemic rat model.

abstract：:High-frequency percussive ventilation (HFPV) may be defined as flow-regulated time-cycled ventilation that creates controlled pressure and delivers a series of high-frequency subtidal volumes in combination with low-frequency breathing cycles. In recent years, the usefulness of HFPV has been clinically assessed as an ...
