Filter by:The primary objective is to gather missing information in order to form a well-founded recommendation on which is the preferred skin pigmentation measurement (PPM) methods in the context of pulse-oximetry.
The investigators' study aims to study how melanin index (mx) affects the deviation between SpO2 and SaO2, which becomes generally greater as hypoxia increases. The studies reviewed grouped individuals by race or have assigned individuals into groups like "dark", "intermediate", or "light" to describe pigmentation. Both of these methods are neither standardized nor objective, looking for race identifiers when it is more useful to be considering skin pigmentation identifiers. Skin pigmentation is a spectrum and it should be treated as such when trying to characterize relationships involving measurable factors such as melanin index. The investigators will similarly measure the deviation between SpO2 and SaO2 however novel in that the investigators will quantitatively measure skin pigmentation via a light reflectance measurement device by Photovault.
The purpose of the study is to demonstrate proper function of the U-TruSignal device via clinical performance testing in a neonatal human subject population under standard clinical conditions. A study with human subjects will provide the needed clinical evidence for assessing the accuracy of the pulse oximeter as recommended by the FDA Guidance Document (Pulse Oximeters - Premarket Notification Submissions [50(k)s]: Guidance for Industry and Food and Drug Administration Staff.)
The objective of this trial is to determine whether an opioid-free general anesthetic (OFA) technique utilizing ketamine, dexmedetomidine, lidocaine, and gabapentin can help reduce postoperative respiratory depression in the post-anesthesia care unit and ward in children with sleep-disordered breathing undergoing tonsillectomy when compared with traditional opioid-containing techniques. It is expected that this OFA regimen will have a measurable reduction on postoperative respiratory depression in children with sleep-disordered breathing.
A study to test the accuracy of SpO2 sensors with various patient monitors, co-oximeters, and modules.
Continuous accurate unobtrusive respiratory rate monitoring may lead to improved patient outcomes, as respiratory rate is thought to be a sensitive marker of patient deterioration. Currently systems are not suitable for long term monitoring, particularly in ambulant patients as they are too restrictive. To ensure that our algorithms are suitable for use in a clinical context we need to demonstrate their performance not only in the optimal situation, healthy volunteers at rest, but also in more challenging situations such as where the person being monitored is moving and also in patients who have conditions which may affect their physiology in such a way that the accuracy of the respiration rate estimation may be affected. No previous study has systematically tested algorithms deriving respiratory rate from either the ECG or the photoplethysmography (PPG) waveforms in a real -world setting. The algorithms work by looking for changes in intervals between heartbeats and also changes in the sizes of the ECG and PPG waveforms, both of which may be caused by respiration. These changes tend to diminish with increasing age and also conditions which alter the chest movement and cardiac reflexes. Thus it is important to test our algorithms' accuracy in participants exhibiting these conditions. It is also important to ensure that the calculations of respiratory rate are accurate across a range of heart rates and respiratory rates. Our testing covers all these variables.
