Xie A, Skatrud J, Puleo D, Morgan B
J Physiol . 1999 Mar; 515 ( Pt 2):621-8. PMID: 10050027
1. Bursts of sympathetic activity in muscle nerves are phase-locked to the cardiac cycle by the sinoaortic baroreflexes. Acoustic arousal from non-rapid eye movement (NREM) sleep reduces the normally invariant...

Katragadda S, Xie A, Puleo D, Skatrud J, Morgan B
J Appl Physiol (1985) . 1998 Feb; 83(6):2048-54. PMID: 9390980
Obstructive and nonobstructive apneas elicit substantial increases in muscle sympathetic nerve activity and arterial pressure. The time course of change in these variables suggests a causal relationship; however, mechanical influences,...

Taha B, Dempsey J, Weber S, Badr M, Skatrud J, YOUNG T, et al.
Sleep . 1998 Feb; 20(11):991-1001. PMID: 9456464
Efficient automated detection of sleep-disordered breathing (SDB) from routine polysomnography (PSG) data is made difficult by the availability of only indirect measurements of breathing. The approach we used to overcome...

Wilson C, Manchanda S, Crabtree D, Skatrud J, Dempsey J
J Appl Physiol (1985) . 1998 Feb; 84(1):269-76. PMID: 9451646
Sleep apnea is associated with episodic increases in systemic blood pressure. We investigated whether transient increases in arterial pressure altered upper airway resistance and/or breathing pattern in nine sleeping humans...

Badr M, Morgan B, Finn L, Toiber F, Crabtree D, Puleo D, et al.
Sleep . 1997 Dec; 20(9):707-14. PMID: 9406322
Sleep state instability is a potential mechanism of central apnea/hypopnea during non-rapid eye movement (NREM) sleep. To investigate this postulate, we induced brief arousals by delivering transient (0.5 second) auditory...

Badr M, Kawak A, Skatrud J, Morrell M, Zahn B, Babcock M
Respir Physiol . 1997 Nov; 110(1):33-45. PMID: 9361150
We wished to determine the effect of reduced ventilatory drive (hypopnea) on upper airway patency in humans during non-rapid-eye-movement (NREM) sleep. We studied nine subjects (58 trials) spanning the spectrum...

Manchanda S, Leevers A, Wilson C, Simon P, Skatrud J, Dempsey J
Respir Physiol . 1996 Aug; 105(1-2):1-16. PMID: 8897646
We quantified volume and frequency thresholds necessary for the inhibition of respiratory motor output during prolonged normocapnic mechanical ventilation in healthy subjects during wakefulness (n = 7) and NREM sleep...

Morgan B, Crabtree D, Puleo D, Badr M, Toiber F, Skatrud J
J Appl Physiol (1985) . 1996 May; 80(5):1627-36. PMID: 8727549
The arterial pressure elevations that accompany sleep apneas may be caused by chemoreflex stimulation, negative intrathoracic pressure, and/or arousal. To assess the neurocirculatory effects of arousal alone, we applied graded...

Iber C, Simon P, Skatrud J, Mahowald M, Dempsey J
Am J Respir Crit Care Med . 1995 Jul; 152(1):217-24. PMID: 7599827
Passive lung inflation in humans causes reflex expiratory prolongation that is abolished by vagal blockade. We have studied two aspects of this classic Breuer-Hering reflex in humans: the effect of...

Simon P, Leevers A, Murty J, Skatrud J, Dempsey J
J Appl Physiol (1985) . 1995 Jul; 79(1):312-23. PMID: 7559237
To evaluate the role of phrenic and sternocleidomastoid afferents as alternate sources of inhibitory feedback during mechanical ventilation, we studied five C2-C3 quadriplegics with sensory denervation of the rib cage...
