... response, following acute PE, is also mediated by a neural reflex. Hypoxia is perceived by carotid chemoreceptors and stimulates the respiratory center. Nevertheless, when experimental PE is induced in animals with denervated carotid chemoreceptors, tachypnea is diminished, but not suppressed. Therefore...

...Jochen D. Schipke; Frederic Lemaitre; Sinclair Cleveland; Kay Tetzlaff This short review focuses on pulmonary injury in breath-hold (BH) divers. When practicing their extreme leisure sport, they are exposed to increased pressure on pulmonary gas volumes, hypoxia, and increased partial gas pressures...

... obese male rats. We hypothesized that the aged muscle would be vulnerable to oxidative stress (hypoxia). Methods: Isometric contractile and endurance properties of the sternohyoid muscle were assessed in vitro with or without the superoxide scavenger Tempol (10 m M ). Muscle fibre size and density were...

Results: Rats exposed to either E-IH or HFD alone showed increases of 161 and 176%, respectively, in oxidative stress (measured as thiobarbituric acid-reactive substances) compared to chow + air controls. However, oxidative stress was lower following...

Conclusions: IAD might be superior to AHI alone in the evaluation of the history of CVEs in mild to moderate OSA patients, and it deserves attention as a possible predictor of future CVEs.

...J.J. Pandit; P.A.

The acute ventilatory response to hypoxia (AHVR) was used as a measure...

A review of the literature on blood gas transport responses to hypoxia indicates that they are influenced not only by altitude, but also by factors related...
