Arousal response to Hypoxia in Newborn Mice 1 Cold Stimulates the Behavioral Response to Hypoxia in Newborn Mice
In newborns, hypoxia elicits increased ventilation, arousal followed by defensive movements and cries. Cold is known to affect the ventilatory response to hypoxia, but whether it affects the arousal response remains unknown. The aim of the present study was to assess the effects of cold on the ventilatory and arousal responses to hypoxia in newborn mice. We designed an original platform measuri...
متن کاملLaryngeal response to nasal ventilation in nonsedated newborn lambs.
Although endoscopic studies in adult humans have suggested that laryngeal closure can limit alveolar ventilation during nasal intermittent positive pressure ventilation (nIPPV), there are no available data regarding glottal muscle activity during nIPPV. In addition, laryngeal behavior during nIPPV has not been investigated in neonates. The aim of the present study was to assess laryngeal muscle...
متن کاملAlveolar hypoxia increases lung fluid filtration in unanesthetized newborn lambs.
We studied the pulmonary vascular response to hypoxia and associated transvascular flux of fluid into the lungs of newborn lambs. After a 2-hour baseline period, 14 unanesthetized lambs, 1-3 weeks old, breathed 10-12% oxygen in nitrogen for 3-6 hours. We measured steady state lung lymph flow, pulmonary arterial and left atrial pressures, blood flow to the lungs, and the concentration of protein...
متن کاملNewborn Lambs
We have previously shown that the pulmonary venoconstriction produced by a stable thromboxane A2 analogue (STAJ is attenuated by prostacyclin (PGIi), but PGI, increases the STA2-induced edema. The present study was designed to determine the effects of STA2 and PGI2 on the fluid balance in isolated blood-perfused newborn lamb lungs. Vascular permeability was evaluated by use of the fluid filtrat...
