To evaluate the intensity of nocturnal hypoxemia associated with sleepiness in Peruvian men with a diagnosis of obstructive sleep apnea (OSA).

Acute hypoxemia results in hypertension, bradycardia, and cardiac output redistribution in fetal sheep. The blood flow redistribution is produced by differential changes in vascular resistance of various fetal organs. ...

Early stages of the novel coronavirus disease (COVID-19) are associated with silent hypoxia and poor oxygenation despite relatively minor parenchymal involvement. Although speculated that such paradoxical findings may be ...

Extracorporeal membrane oxygenator (ECMO) is a well-established therapy for respiratory failure. Refractory hypoxemia, despite the use of ECMO, remains a challenging problem. The ECMO circuit may not provide enough oxygenation ...

The fetal llama (Lama glama; a species adapted to live in chronic hypoxia in the highlands of the Andes) did not increase cerebral blood flow and reduce the brain oxygen uptake during hypoxemia. Although nitric oxide (NO) ...

Cerebral blood flow (CBF) in the llama fetus does not augment during acute hypoxemia, decreasing cerebral oxygen delivery. To investigate whether VO2 cer could be maintained during hypoxemia by increasing cerebral oxygen ...

We tested the hypothesis that the llama fetus has a blunted cardiovascular chemoreflex response to hypoxemia by investigating the effects of acute hypoxemia on perfusion pressure, heart rate, and the distribution of the ...

Background: COVID-19 is a disease associated with an intense systemic inflammation that could induce severe acute respiratory distress syndrome (ARDS), with life-threatening hypoxia and hypercapnia. We present a case where ...
