The impacts of prone position on the blood oxygen saturations and heart rates of preterm infants under the mechanical ventilation
Background: The methods of baby's position are an important critical factor in ventilation and oxygenation of tissues. Although the prone position as one of the recommended position has beneficial effect on the development of premature infants, little research has been done. Methods: In a clinical trial among mechanically ventilated infants, hospitalized in the neonatal intensive care units (N...
متن کاملReactive oxygen species: finding the right balance.
Appropriate regulation of reactive oxygen species (ROS) has a significant impact on health and disease. ROS includes oxygen ions (O2̇) free radicals (superoxide [O, 2] and hydroxyl radicals), and peroxides (hydrogen peroxide [H2O2]) and are the products of normal oxygen consuming metabolic process in the body. ROS are small and highly reactive molecules with important cell signaling roles when m...
متن کاملContributions of heart rate and contractility to myocardial oxygen balance during exercise.
The respective contributions of heart rate (HR) reduction and left ventricular (LV) negative inotropy to the effects of antianginal drugs are debated. Accordingly, eight instrumented dogs were investigated during exercise at spontaneous and paced HR (250 beats/min) after administration of either saline, atenolol, or ivabradine (selective pacemaker current channel blocker). During exercise, aten...
متن کاملEffects of position on oxygen saturation and heart rate in very low birth weight neonates
Background: Desirable oxygenation of preterm newborns has particular importance, for this reason different methods have been proposed to improve oxygenation of the newborns; one of these methods is the newborns' position. The aim of this study was to determine the effect of the position of low birth weight neonates on arterial oxygen saturation and heart rate. Methods: This interventional st...
متن کاملOxygen consumption and heat balance in the cot-nursed baby.
Hey, E. N., and O'Connell, B. (1970). Archives of Disease in Childhood, 45, 335. Oxygen consumption and heat balance in the cot-nursed baby. Oxygen consumption and heat balance have been studied in 42 clothed babies under varied environmental temperature conditions. The information obtained has made it possible to compare the thermal environment provided by an incubator with that provided by an...
