Aims: Today, due to the failure of non-surgical methods in the treatment of obesity, surgical procedures such as sleeve gastrocetomy are used. Similar to other invasive interventions, sleeve gastrectomy causes an imbalance in hemodynamic parameters. The aim of this study was to determine the effect of early mobilization on hemodynamic parameters in patients undergoing sleeve gastrectomy. Mater...

www.ajcconline.org • BACKGROUND Pulse oximetry is commonly used to monitor oxygenation in neonates, but cannot detect variations in hemoglobin. Venous and arterial oxygen saturations are rarely monitored. Few data are available to validate measurements of oxygen saturation in neonates (venous, arterial, or pulse oximetric). • PURPOSE To validate oxygen saturation displayed on clinical monitors ...

a significant reduction in arterial blood oxygen saturation during fiberoptic bronchoscopy has been proved but it is not yet known whether all patients need supplemental oxygen during this procedure. the aim of study is to examine the relationship between peak expiratory flow rate (pefr) before bronchoscopy and oxygen desaturation during bronchoscopy. measurement of pefr (% predicted) performed...

conclusions closed suction caused fewer disturbances in patients’ hemodynamic condition, took shorter time, and is more economical. therefore, this method can replace open suction method in caring of severely critically ill patients. results no significant differences were observed between the two suctioning methods in terms of mean systolic blood pressure (p = 0.075), diastolic blood pressure ...

background : mechanical ventilation is used for some infants in neonatal intensive care units (nicu) due to many physiological and clinical causes. since these patients have endotracheal tubes, cleaning and keeping the airways open through suctioning should be done to increase oxygenation. this study aimed to evaluate effect of open and closed suctioning methods on respiratory parameters of inf...

Multi-wavelength photometers, blood gas analysers and pulse oximeters are widely used to measure various oxygen-related quantities. The definitions of these quantities are not always correct. This paper gives insight in the various definitions for oxygen quantities. Furthermore, the possible influences of dyshaemoglobins and fetal haemoglobin on the accuracy of pulse oximetry are discussed. As ...

Background: Considering the susceptibility of preterm infants to disturbances of vital signs, this study was conducted to investigate the effects of using plastic covers on regulation of vital signs in preterm neonates.Methods: This randomized, cross-over, clinical trial was carried out on 80 preterm infants admitted to neonatal intensive care unit (NICU) of Taleghani Hospital, Tabriz, Iran. Th...

The effects of nebulised salbutamol driven by compressed air or oxygen were compared in a randomised crossover study during 27 attacks of acute asthma. Arterial oxygen saturation fell by 2-6% during or after treatment in 10 cases: seven with compressed air, two with oxygen, and one with both driving gases. Hypoxaemia occurred in younger children and in those who fell asleep, but was not related...
