The incidence of hypoxia at the time of upper gastrointestinal endoscopy can be greatly reduced by the administration of supplemental oxygen via nasal cannulae. Using dual thermistors in the mouth and nostrils of patients undergoing upper gastrointestinal endoscopy, the present study demonstrates that ...
However, 100% O2 is often given via nasal cannula during ophthalmology procedures, and little is known regarding the periocular O2 concentrations. We create a model to replicate an open-system delivery of O2 and concurrently measure O2 levels in the periocular region to assess the fire risk of ...
Effect of the Anatomic Reservoir on Low-Flow Oxygen Delivery Via Nasal Cannula: Constant Flow Versus Pulse Flow With Portable Oxygen Concentrator BACKGROUND: The F(IO(2)) for a nasal cannula with constant flow (CF) depends on the anatomic reservoir (AR), which is affected by changes in freq...
Patients breathed compressed air or supplemental oxygen via nasal cannulas on consecutive nights in a randomised, double blind, crossover trial. Quality of sleep was assessed by questionnaire and by electroencephalographic sleep staging. The study had a power of 80% to detect, at the 0.05 level...
Preterm infants on supplemental oxygen via oxygen environment maintained by a servo-controlled system or nasal cannula with flow rates ≤1.0 L per kg per minute were crossed over every 24 hours for 96 hours. Data were collected electronically to capture real time numeric and waveform data from ...
We have compared the effects of 2 liters.min 1 of oxygen given orally via the bite-guard with the same flow rate via nasal cannulas and have also examined the effects of pre-oxygenation. Results of this study at a flow rate of 2 liters.min 1 have been compared with previously ...
Subjects underwent a cardiopulmonary exercise test to determine their maximal oxygen update (VO2max). They then performed two constant workrate exercise tests at 80% VO2max, one while breathing placebo air and another while breathing O2, each delivered at 4 L/min via a nasal cannula. With O2...
Methods After IRB approval and informed consent, 42 patients undergoing laparoscopic bariatric surgery were randomly assigned to receive either 80% inspired oxygen via a PULMANEX Hi-Ox Mask (Viasys MedSystems, Wheeling, IL) (10L/min) or 30% oxygen via nasal cannula (2L/min) after surgery ...
Infants received room air (RA) or SupOx via nasal cannula at 0.25 L/min. Results. Quiet sleep density was increased during SupOx (33.3 ± 10.8% vs 26.6 ± 10.0% total sleep time [TST] in RA), and a reciprocal decrease in active sleep density was observed (61.5 ± 11.1% vs 68.4 ±...
Bottled oxygen delivered at 2 L x min(-1) via nasal cannula was prescribed for her journey. Preflight SpO2 without supplemental oxygen was 92%. Mean in-flight SpO2 was well maintained at 93% while on oxygen at rest. There were four significant hypoxic events, which included light physical ...
