NCT ID: NCT04964609 Completed - Oximetry Clinical Trials

EmbracePlus SpO2 Accuracy Validation

Start date: June 16, 2021
Phase: N/A
Study type: Interventional

The aim of this study is to test the accuracy of EmbracePlus computed SpO2 during mild, moderate and severe hypoxia (a lower-than-normal concentration of oxygen in arterial blood); ie, a range of arterial HbO2 saturations from 100 to down to 70%. This is done by comparing the reading of the the subject device during brief, steady state hypoxia with a gold-standard measurement of blood oxyhemoglobin (hemoglobin carrying oxygen) saturation, that is arterial blood sample processed in a laboratory.

NCT ID: NCT04562584 Completed - Oximetry Clinical Trials

Pulse Oximeter Hypoxia

Start date: June 3, 2020
Phase: N/A
Study type: Interventional

The aim of this project is to test the accuracy of pulse oximeters (devices intended to measure oxygen saturation in blood noninvasively) during mild, moderate and severe hypoxia (a lower-than-normal concentration of oxygen in arterial blood); ie, a range of arterial HbO2 saturations from 100 to down to 70%. This is done by comparing the reading of the pulse oximeter during brief, steady state hypoxia with a gold-standard measurement of blood oxyhemoglobin (hemoglobin carrying oxygen) saturation, that is arterial blood sample processed in a laboratory.

NCT ID: NCT04380389 Completed - Oximetry Clinical Trials

Accuracy of ScanWatch Pulse Oximeter With Profound Hypoxia

Start date: March 11, 2020
Phase: N/A
Study type: Interventional

Performance testing of pulse oximeters. The protocol involves brief stable arterial oxygen desaturation in healthy volunteers and sampling arterial blood when a stable level of hypoxia has been attained. The blood sample is analyzed for oxygen saturation with a gold standard bench CO-oximeter. This protocol is aligned with the latest ISO and FDA guidance documents for pulse oximeter testing.

NCT ID: NCT04324385 Completed - Oximetry Clinical Trials

Accuracy of Pulse Oximeters With Profound Hypoxia

Start date: April 9, 2019
Phase:
Study type: Observational

To test the accuracy of a non-invasive blood oxygen saturation monitor which is placed on a subject with profound hypoxia.

NCT ID: NCT03710993 Completed - Oximetry Clinical Trials

Accuracy Assessment of Beddr Oximeter

Start date: July 30, 2018
Phase:
Study type: Observational

Accuracy performance of Beddr oximeter

NCT ID: NCT03710980 Completed - Oximetry Clinical Trials

Accuracy of Pulse Oximeters With Profound Hypoxia

Start date: September 18, 2018
Phase:
Study type: Observational

This study to assess the oxygen saturation accuracy of the Beddr SleepTuner in profound hypoxia.

NCT ID: NCT03534271 Completed - Oximetry Clinical Trials

The Accuracy of Smartphone Pulse Oximetry in Patients Visiting an Outpatient Pulmonary Function Lab for a 6-Minute Walk Test

Start date: April 27, 2018
Phase:
Study type: Observational

The primary aim of this research is to determine the accuracy of smartphone pulse oximeters in detecting blood oxygen saturations, episodes of desaturations, and heart rate by comparing results to a Masimo© hospital-grade pulse oximeter.

NCT ID: NCT03250065 Completed - Oximetry Clinical Trials

The Sensing ET Tube

SETT
Start date: March 3, 2017
Phase: N/A
Study type: Interventional

This proposal describes the development of a 'Sensing ET Tube'. This device will replace the standard endotracheal (ET) tube used in anaesthesia and in ventilated intensive care patients and provide key vital signs monitoring utilising optoelectronic sensors. Continuous monitoring of patients' arterial oxygen saturation is essential during surgery, however pulse oximeters often misread or fail altogether as a result of peripheral vasoconstriction, hypotension or hypovolaemia. The Sensing ET Tube will allow continuous measurement of oxygen saturation and other parameters, such as pulse rate, from a single internal site, and will reduce the number of surface sensors placed on the skin and the number of electrical connections to the patient. The applicants have already developed similar sensor technology in the oesophagus and other internal locations. A pilot clinical evaluation of the device will be completed in anaesthetised patients undergoing surgery. The project will lead to further development of a multi-sensor tracheal platform for comprehensive anaesthesia and intensive care monitoring.

NCT ID: NCT01530360 Completed - Premature Infants Clinical Trials

Cerebral Oxygenation to Guide Medical Interventions in Extremely Preterm Infants

SafeBoosC-p
Start date: September 2011
Phase: Phase 1
Study type: Interventional

Regional tissue oxygenation (rStO2) can be monitored by near-infrared spectroscopy. The investigators planned a SafeBoosC phase II trial to test if a reduction of the burden of hyper- and hypoxia can be accomplished during the first three days of life in infants born before 28 completed weeks of gestation. The investigators developed a treatment guideline and a randomised trial design to evaluate if cerebral rStO2 spent out of range in %hours can be reduced by 50%. The present trial is a non-randomised pilot study of the intervention in 10 infants.
