Controlled Clinical TrialThe Effects of Exercise on Right Ventricular Contractility and Right Ventricular - Arterial Coupling in Pulmonary Hypertension.
Exercise tolerance is decreased in patients with pulmonary hypertension (PH). It is unknown whether exercise intolerance in PH coincides with an impaired rest-to-exercise response in right ventricular (RV) contractility. ⋯ In contrast to control subjects, patients with PH were unable to increase Ees during submaximal exercise. Failure to compensate for the further increase in Ea during exercise led to deterioration in Ees/Ea. Furthermore, ΔPAP did not reflect ΔEes but rather the change in heart rate.

Official american thoracic society technical standards: flexible airway endoscopy in children.
Flexible airway endoscopy (FAE) is an accepted and frequently performed procedure in the evaluation of children with known or suspected airway and lung parenchymal disorders. However, published technical standards on how to perform FAE in children are lacking. ⋯ These ATS-sponsored technical standards describe the equipment, personnel, competencies, and special procedures associated with FAE in children.
