The method of Deibler, Holmes, Campbell, and Gans (1959) is a quick, accurate, and reliable method for the determination of oxygen saturation. The results should be calibrated against those obtained by the Van Slyke method, and the setting, sensitivity, and reliability of the spectrophotometer should be carefully established. This is especially necessary to meet the stringent requirements for a...

We present a frequency-domain optical method for real-time noninvasive measurement of absolute tissue and arterial saturation. This method is based on quantitative measurement of the tissue absorption spectrum (for tissue saturation) and of the amplitude of the arterial-pulsation-induced absorption oscillations (for arterial saturation) at eight wavelengths in the range 633-841 nm. We report re...

background: prematurity is the main cause of death in infants under one years of age and is the main reason for nicu hospitalization. the stressful environment of nicu exposes preterm infants to inappropriate stimuli. this study aimed to determine and compare the mean of heart rate and oxygen saturation of premature infants before and during a designed program in nicu. methods: in a clinical tr...

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 ra...

PURPOSE. To determine whether retinal vessel oxygen saturation is affected in primary open-angle glaucoma (POAG) patients. METHODS. Retinal oxygen saturation in patients with POAG was measured in retinal vessels with a spectrophotometric retinal oximeter in darkness, and visual fields were obtained. Oxygen tension (Po(2)) was calculated from oxygen saturation values. Statistical analysis was pe...

Sir,—The article concerning the incidence of respiratory complications and hypoxic episodes during inhalation induction with isoflurane in children [1], raises several interesting points. The authors compared the incidences of three respiratory complications: coughing, breath-holding and laryngospasm during induction of anaesthesia; unfortunately, these complications were not clearly denned. We...

Most often, our waterways are being polluted by municipal, agricultural and industrial wastes. When this happens, much of the available dissolved oxygen is consumed by aerobic bacteria in decomposing the waste, thereby robbing other aquatic organisms of the oxygen they need to live. In this paper, we consider the solution of the optimal control problem for the modified Dissolve Oxygen(DO)/ Biol...
