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 ...

There have been extensive studies on the performance of IEEE 802.11 networks, most of which focus on the saturation regime where user queues are always full. This paper departs from prior work in that we focus on non-saturated regimes. Specifically, we consider two scenarios: one consisting of a mixture of saturated and non-saturated users, the other consisting of users of buffer size one. In b...

OBJECTIVE Previous work has found cerebral oxygen extraction to decrease during hypothermic cardiopulmonary bypass in children. To elucidate cardiopulmonary bypass factors controlling cerebral oxygen extraction, we examined the effect of perfusate temperature, pump flow rate, and hematocrit value on cerebral hemoglobin-oxygen saturation as measured by near infrared spectroscopy. METHODS Forty...

OBJECTIVES To quantify the documentation of vital signs in children attending accident and emergency (A&E) for asthma and to assess whether indicators of severity were used appropriately. METHODS Records of all children aged 3 to 14 attending A&E for the treatment of asthma in four London hospitals over a three month period were examined for documentation of heart rate, respiratory rate, peak...

in the management and evaluation of asthma, simple instruments for measurements of peak expiratory flow rate (pefr) are necessary. the aim of this study was to determine normal pefr of the healthy children in babol, iran. this study was randomly done on 1050 students (primary and secondary schools) in babol. mini-wright peak flow meter was used for measurement of pefr. the range of age, weight ...

soil detachment is known as an important process in soil erosion and its quantification is necessary to establish a basic understanding of erosion. this study was carried out to find the best flow erosivity indicator(s) for predicting detachment rate at low slopes. for this purpose, 12 experiments including 6 flow discharges (75, 100, 125, 150, 175 and 200 ml/s) and 2 slope gradients (1.5 and 2...

A trial was conducted of continuous nebulised salbutamol and oral once a day prednisolone in a group of 11 children with status asthmaticus (group A) and compared with a conventional protocol comprising aminophylline infusion and intravenous hydrocortisone every six hours in a matched control group (group B). Monitoring by a clinical asthma score, pulse oximetry (oxygen saturation, SaO2), and p...

abstract land surface hydrological models has importance in the determination of soil moisture and temperature, the rate of evapotranspiration, stream flow by emphasis on the land surface physical and dynamic process descriptions. in this research, vic land surface hydrological model has been used for the land surface temperature and stream flow determination. the vic runoff simulation in each ...

objective: the aim of the present study was to evaluate unstimulated salivary flow rate and oral symptoms in menopausal women. materials and methods: a total of 200 individuals including 100 women in their menopause (case group) and 100 men in the same age range (control group) participated in this analytic descriptive investigation. none of the patients were being treated for any systemic dise...
