introduction: this study aimed to investigate the effect of music on pain, anxiety and vital signs in children undergoing colonoscopy.   method and materials: this randomized study was carried out on 101 children (7 to 14 years old) requiring colonoscopy. children were randomly allocated to a control or case group. the case group was played relaxing music (by clayderman) during the procedure. s...

Arterial oxygen saturation has not been assessed sequentially in conscious mice as a direct consequence of an in vivo murine model of acute lung injury. Here, we report daily changes in arterial oxygen saturation and other cardiopulmonary parameters by using infrared pulse oximetry following intratracheal lipopolysaccharide (IT-LPS) for up to 9 days, and following IT-phosphate buffered saline u...

BACKGROUND High altitude is associated with both low pulse oxygen saturation at birth and more pre-term deliveries. The present study was performed to determine pulse oxygen saturation in newborns at term in Cerro de Pasco (4340 m) and Lima (150 m) to test the hypothesis that low pulse oxygen saturation at birth at high altitudes was not observed at term deliveries. METHODS The present study ...

This review gives an account of some of the factors affecting the transport of oxygen from the lungs until its final discharge in the tissues. The sequence of physiological and metabolic processes to be described may be considered collectively as the 'coarse adjust-ment' of oxygen transport. The 'fine adjustment' will be discussed in the succeeding chapter which surveys the local factors influe...

 ABSTRACT Background: Acute bronchiolitis is the most common form of lower respiratory tract infection in infancy. There are numerous contradictory reports regarding the efficacy of nebulized bronchodilators in the management of infants with acute bronchiolitis. This study was designed to compare the efficacy of nebulized epinephrine with salbutamol for treatment of the disease. Methods: In a r...

BACKGROUND Determination of the blood oxyhemoglobin saturation in the retinal vessels of the eye can be achieved through spectrophotometric retinal oximetry which provides access to the state of oxyhemoglobin saturation in the central nervous system circulation. The purpose of this study was to test the capability of the Oxymap T1 oximeter to detect systemic hypoxemia and the effect of suppleme...
