Hypoxic pulmonary vasoconstriction in reptiles: a comparative study of four species with different lung structures and pulmonary blood pressures
(Amer Physiological Soc, 2005-11-01)
Low O-2 levels in the lungs of birds and mammals cause constriction of the pulmonary vasculature that elevates resistance to pulmonary blood flow and increases pulmonary blood pressure. This hypoxic pulmonary vasoconstriction ...

Noninvasive Ventilation in a Pregnant Patient With Respiratory Failure From All-Trans-Retinoic-Acid (ATRA) Syndrome
(Daedalus Enterprises IncIrvingEUA, 2009)
Pathophysiological Basis of Acute Respiratory Failure on Non-Invasive Mechanical Ventilation
(Bentham Science Publishers, 2015)
Noninvasive mechanical ventilation (NIMV) was created for patients who needed noninvasive ventilator support, this procedure decreases the complications associated with the use of endotracheal intubation (ETT). The application ...

The breathing pattern and the ventilatory response to aquatic and aerial hypoxia and hypercarbia in the frog Pipa carvalhoi
(Elsevier B.V., 2012-07-01)
Anuran amphibians are known to exhibit an intermittent pattern of pulmonary ventilation and to exhibit an increased ventilatory response to hypoxia and hypercarbia. However, only a few species have been studied to date. ...
