background & aim : pulse oximetry is a frequently used and standard non-invasive method for monitoring oxygen (o2)-saturation in blood. many factors including dark skin and pigmentation may effect on rate of saturation of the blood oxygen absorbed by pulse oximetry. the effect of nail polish and/or henna color on blood oxygen has not been yet identified and the present study has been carried ou...
Introduction: Artificial airway stimulates the sympathetic system and the loss of ciliated cells and the accumulation of secretions. Therefore, since these patients do not have the ability to discharge, periodic suction is needed. This study aimed at comparing the effect of open suction endotracheal tube using 2 different sized suction catheters on arterial blood oxygen saturation in critical c...
This research, which is semi- experimental is focused on the influence and comparison intravenous diazepam with intravenous midazolam as premedication in anesthesia on the saturation arterial blood oxygen before surgical operation, "pan patients who are in risk one under general anesthesia in the operating rooms of the hospitals affiliated to Iran University of Medical Sciences and Heal...
abstract background: stressors in the intensive care unit (icu) impair patients’ comfort, excite the stress response, and increase oxygen consumption in their body. non‑medical interventions are recommended by several studies as a treatment to improve comfort in the icu patients. sensory stimulation is one of the most important interventions. since arterial blood oxygen saturation is an importa...
background. given the influence of systemic blood pressure on pulpal blood flow, anxiolytics prescribed may alter the pulpal blood flow along with the local anesthetic solution containing a vasoconstrictor. this study evaluated the impact of preoperative anxiolytics and vasoconstrictors in local anesthetic agents on pulpal oxygen saturation. methods. thirty anxious young healthy individuals wit...
Background and Aim: Intratracheal suctioning is a standard method of nursing care for intubated patients with the aim of cleaning airway for good oxygenation. The aim of this study was to evaluate the effects of intratracheal suctioning on blood pressure, heart rate, and arterial oxygen saturation. Materials and Methods: This was a semi-experimental research in which the patients admitted t...
the quality of the river water is assessed in different months in different stations to evaluate the change in the quality in re1ation with the various point sources along the river. thirteen parameters were measured in the samples manually taken from three meters off shore in 20 cm. depth in four points representing the quality in four reaches under consideration. the results revealed that nat...
Background: Pulseoximetry is widely used in the critical care setting, currently used to guide therapeutic interventions. Few studies have evaluated the accuracy of SPO2 (puls-eoximetry oxygen saturation) in intensive care unit after cardiac surgery. Our objective was to compare pulseoximetry with arterial oxygen saturation (SaO2) during clinical routine in such patients, and to examine the eff...
Ross, JOE M., HILTON M. FAIRCHILD, JOE WELDY, AND ARTHUR C. GUYTON. Autoregulation of blood flow by oxygen lack. Am. J. Physiol. 202(1): 2 r-24. Ig62.-The effect of hemoglobin oxygen saturation upon blood flow through the hind leg of the dog was studied by perfusing the femoral arteries of five normal dogs with blood, the oxygen saturation of which was varied between 100% and o%, and by perfusi...
