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...

Phasic bursting in the hypoglossal nerve can be uncoupled from phrenic bursting by application of positive end-expired pressure (PEEP). We wished to determine whether similar uncoupling can also be induced in other respiratory-modulated upper airway (UAW) motor outputs. Discharge of the facial, hypoglossal, superior laryngeal, recurrent laryngeal, and phrenic nerves was recorded in anesthetized...

During the course of study on alteration in EEG pattern produced by changing ventilation, we noticed spontaneous EEG fluctuation in which two types of activities alternated at regular intervals in about half the series of experiments. Cortical and subcortical electrical activity as well as phrenic nerve volley and blood pressure was recorded in curarized cats under artificial respiration. The p...

1618 Communications to the Editor monectomy. He was discharged home but died on the 85th postoperative day. 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...

Lower cranial and phrenic nerve involvement is exceptional in hereditary neuropathy with liability to pressure palsies (HNPP). Here we report the occurrence of reversible laryngeal and phrenic nerve involvement in a patient with HNPP. The patient recalled several episodes of reversible weakness and numbness of his feet and hands since the age of 30 years. His medical history was uneventful, apa...

INTRODUCTION Phrenic nerves have important roles on the management of respiration rhythm. Diaphragm paralysis is possible in phrenic nerve roots ischemia in subarachnoid hemorrhage (SAH). We examined whether there is a relationship between phrenic nerve root ischemia and respiratory disturbances in SAH. MATERIAL AND METHODS This study was conducted on 5 healthy control and 14 rabbits with exp...
