Neonates with respiratory distress syndrome (RDS), who are treated according to INSURE protocol; require arterial blood gas (ABG) analysis to decide on appropriate management. We conducted this study to investigate the validity of pulse oximetry instead of frequent ABG analysis in the evaluation of these patients. From a total of 193 blood samples obtained from 30 neonates <1500 grams with RDS,...

IMPORTANCE Evaluation of pediatric obstructive sleep apnea in resource-limited health care systems necessitates testing modalities that are accurate and more cost-effective than polysomnography. OBJECTIVE To trace the clinical pathway of children referred to our sleep laboratory for possible obstructive sleep apnea who were evaluated using nocturnal pulse oximetry and the McGill Oximetry Scor...

OBJECTIVE To illustrate the possible role of cerebral oximetry and stroke distance as measured by Doppler ultrasound in monitoring the critically ill patient non-invasively in the emergency department. METHODS Five critically ill patients were monitored with either cerebral oximetry or both cerebral oximetry and stroke distance (the distance travelled by blood in the aorta with each ventricul...

PURPOSES Pulse CO-oximetry (Rad-57; Masimo Corp, Irvine, CA) has been available since 2005. To date, all published clinical studies have focused on clinical reliability and whether the device enhances case finding through screening of various populations. This study examines whether use of pulse CO-oximetry shortens the time to diagnosis and treatment of patients with carbon monoxide (CO) poiso...

The pulse oximetry plethysmographic signal resembles the peripheral arterial pressure waveform, and the degree of respiratory variation in the pulse oximetry wave is close to the degree of respiratory arterial pulse pressure variation. Thus, it is tempting to speculate that pulse oximetry can be used to assess preload responsiveness in mechanically ventilated patients. In this commentary we bri...

mouth breathing might not always result in hypoxia, but can contribute to it. the aim of the present study was to determine the effect of mouth breathing on hypoxia. based on a pilot study, 323 patients with mouth breathing were selected. assessment of mouth breathing was based on clinical examination and questionnaires filled out by patients and their companions. the patients were also examine...

BACKGROUND AND PURPOSE Patent foramen ovale (PFO) may play an important role as a risk factor for ischemic stroke and some other neurological conditions. There is a need for low-cost and noninvasive methods for the detection of PFO. This study evaluates the accuracy of two simple bedside tests, the dye dilution method and ear oximetry, in the detection of PFO. METHODS Dye dilution curves and ...

PURPOSE To determine the utility of pulse oximetry as a routine fifth vital sign in acute pediatric assessment. DESIGN Prospective study using pulse oximetry to measure oxygen saturation in children presenting to emergency department triage. Saturation values were disclosed to clinicians only after they had completed medical evaluations and were ready to discharge or admit each child. We meas...
