Background: Neonatal respiratory distress syndrome (NRDS), a life-threatening pulmonary disorder, involves 1% of all deliveries worldwide. Shallow breathing causes restlessness in infants, which itself affects pulmonary function; thus, sedative medications are used to preserve better pulmonary function. There are different opinions about the benefits and superiority of these dr...

background: cuffed pharyngeal tube is a device designed for ventilation of anesthetized patients. cpt has advantages over face mask including: maintaining of face mask can be difficult and boring after several minutes and mobility of the practitioner is reduced due to involvement of hands. mask pressure can cause soft tissue and nerve damage around the nose. anesthetic gas leakage from the mask...

Background: Alveolar hypoxia induces monophasic pulmonary vasoconstriction in vivo, biphasic vasoconstriction in the isolated pulmonary artery, and controversial responses in the isolated perfused lung. Pulmonary vascular responses to sustained alveolar hypoxia have not been addressed in the isolated perfused rat lung. In this study, we investigated the effect of sustained hypoxic ventilation o...

A. Aerosol Ventilation Scintigraphy A diagnostic imaging test that records the bronchopulmonary distribution of an inhaled radioactive aerosol within the lungs. B. Gas Ventilation Scintigraphy A diagnostic imaging test that records the pulmonary distribution of a radioactive gas during breathing maneuvers. C. Pulmonary Perfusion Scintigraphy A diagnostic imaging test that records the distributi...

deep vein thrombosis (dvt) is an important life threatening condition that is difficult to diagnose, particularly in the early stages. looking for dvt in lower limb can be considered ancillary in suspected cases of pulmonary embolism (pe) indirectly highlighting a cause and effect relationship of a single disease (i.e cause being dvt and effect is the assault on the lung vasculature). prompt an...

Xenon-133 lung ventilation and perfusion scans were done preoperatively after cardiac catheterization and cineangiocardiography in 19 children; 6 had pulmonary atresia with an intact ventricular septum and hypoplastic right ventricle, 4 pulmonary atresia with associated complex univentricular heart, and 9 extreme Tetralogy of Fallot. The four patients with discrepancies in the sizes of the left...
