Filter by:Finger pulse oximetry SpO2 is widely used to estimate arterial oxygen saturation SaO2. Current Spo2 targets do not take into consideration the many variables that affect that correlation in particular skin pigmentation. This study aims to evaluate different FDA approved pulse oximeters (Nonin co-pilot, massimo Radical 7, Philips-standard of care monitor, innovo premium iP900BP, nellcor PM1000N, Nano100) with SaO2 reference values obtained by an arterial blood gas in subjects with different skin pigments measured by a skin color scale as well as self-identification of race.
This investigator-initiated, prospective, randomized, blinded, multi-center, controlled trial will investigate the effect of a restrictive vs. liberal oxygenation-strategy in patients hospitalized with acute heart failure with pulmonary congestion. Patients will be randomized 1:1 in the emergency department to either liberal or restrictive oxygenation after providing informed written consent. 1. Liberal oxygenation group = SpO2 target of 96%. 2. Restrictive oxygenation group = SpO2 target of 90%. The allocation will be concealed through the use of an oxygen-delivery robot, termed O2MATIC. The study will include 122 patients.
This is a prospective observational study designed to quantify and understand errors in pulse oximetry in hospitalized patients in relation to their skin pigmentation. It is driven by three recent retrospective studies showing missed diagnosis of hypoxemia in patients across a spectrum of skin pigmentation, defined as blood SaO2 <90% when their pulse oximeter reads 92% or greater.
This study within a trial (SWAT) will be a sub-study of the UK-ROX trial (ISRCTN13384956), which is currently running in intensive care units across the UK. UK-ROX is large-scale randomised controlled trial evaluating conservative oxygen therapy (a target SpO2 of 88-92%) versus usual oxygen therapy in mechanically ventilated adult patients admitted to ICUs in the UK. The purpose of this observational sub-study is to compare pulse oximeter-derived peripheral oxygen saturation (SpO2) values to co-oximeter-derived arterial oxygen saturation (SaO2) measurements from arterial blood gas (ABG) samples, for a range of fingertip pulse oximeters in an ethnically diverse group of adult patients admitted to UK intensive care units (ICUs). Approximately 900 patients will be recruited over 12 month period from 24 sites to provide an anticipated 10,800 paired SpO2 and SaO2 measurements. Patient skin tone will be objectively measured using a handheld spectrophotometer. Data from the sub-study will be used to determine the accuracy of the tested pulse oximeters across a range of skin tones and arterial oxygenation levels.
Nasotracheal Intubation with Videolaryngoscopy versus Direct Laryngoscopy in Infants (NasoVISI) Trial is a prospective randomized multicenter study. The study will be conducted at 8 centers in the United States. It is expected that approximately 700 subjects enrolled to product 670 evaluable subjects.The randomization is 1:1 naso tracheal intubation with the Storz C-Mac Video Videolaryngoscopy (VL) or the Standard Direct Laryngoscope (DL). The primary objective is to compare the nasotracheal intubation (NTI) first attempt success rate using VL vs. DL in infants 0-365 days of age presenting for cardiothoracic surgery and cardiac catheterizations.
The aim of this research project is to determine the effect of repeated maximal voluntary apneas on glucose uptake during an oral glucose tolerance test in healthy individuals, individuals with prediabetes and patients with type 2 diabetes.
This study seeks to define the ultrasound profile of patients with COVID-19, and document the progression of these ultrasound findings to develop prognostication and clinical decision instruments that can help guide management of patient with COVID-19. Primary aims include the development of ARDS, refractory hypoxemia, acute cardiac injury, pulmonary embolism, pneumothorax or death. Secondary aims include potential change in CT and plain film utilization given the use of POCUS, as well as emergency department and inpatient LOS (length of stay).
The purpose of this study is to determine the effects of Almitrine administration on oxygenation in COVID-19 patients with acute respiratory distress syndrome treated by high-flow nasal canula oxygen therapy as first-line ventilatory support.
Hypoxia in single lung ventilation versus two lung ventilation in video assisted lung surgeries
The oximeter is used to monitor intensive care patients undergoing oxygen therapy. It indicates pulsed oxygen saturation (SpO2), a reflection of arterial oxygen saturation (SaO2) which enables detection of hypoxemia and hyperoxia, both deleterious state. Current SpO2 recommendations aim to reduce both risk of hypoxemia and hyperoxia. SpO2 is considered the 5th vital sign. Current recommendations for SpO2 targets do not consider the variability of oximeters used in clinical practice. This variability and lack of specification represent an obstacle to an optimal practice of oxygen therapy. Thus, this study aims to compare the SpO2 values of different oximeters (Nonin, Masimo, Philips, Nellcor) used in clinical practice with the SaO2 reference value obtained by an arterial gas in order to specify the precision and the systematic biases of the oximeters studied. This data will also make it possible to refine the recommendations concerning optimal oxygenation
