Comparison of magnetic and electrical phrenic nerve stimulation in assessment of phrenic nerve conduction time.
Cervical magnetic stimulation (CMS), a nonvolitional test of diaphragm function, is an easy means for measuring the latency of the diaphragm motor response to phrenic nerve stimulation, namely, phrenic nerve conduction time (PNCT). In this application, CMS has some practical advantages over electrical stimulation of the phrenic nerve in the neck (ES). Although normal ES-PNCTs have been consiste...

ELDRIDGE, FREDERIC L. Relationshz) between phrenic nerve activity and ventdation. Am. J. Physiol. 221(Z) : 535-543. 197 1 .-Phrenic nerve discharges were recorded in anesthetized cats simultaneously with a range of tidal volumes. Nerve impulses were processed in a variety of ways. Total impulses per breath and peak impulse frequency correlated poorly with tidal volume. Integrated electrical act...
متن کاملReflex effects of aerosolized histamine on phrenic nerve activity.
Studies were conducted in anesthetized, paralyzed dogs on the effect of aerosolized histamine on phrenic nerve activity. The paralyzed dogs were ventilated in phase with their recorded phrenic nerve activity at a constant inspiratory flow-rate, using a cycle-triggered ventilator. Phrenic nerve activity was measured before and during administration of aerosolized histamine while the inspiratory ...

While the majority of studies examining preoperative risk have acknowledged that hypercarbia represents a relative contraindication to lung resection, a threshold value of 45 mm Hg has not been formally evaluated.3 Most studies have not listed PaCO2 values, although it is likely the major...
متن کاملPhrenic nerve activity and ventilation during lung oedema in rabbits.
Single fibre and "integrated" phrenic nerve activity was recorded in anaesthetized spontaneously breathing rabbits, during experimentally induced lung oedema. Tidal volume, blood pressure, end-tidal CO2, were monitored. In oedema the number of impulses in each volley slightly decreased while the discharge frequency was increased relatively to control values. The latter effect was due to the inc...
