Prediction of Opioid-Induced Respiratory Depression on Inpatient Wards Using Continuous Capnography and Oximetry: An International Prospective, Observational Trial

Anesthesia and Analgesia, 2020
BACKGROUND: Opioid-related adverse events are a serious problem in hospitalized patients. Little is known about patients who are likely to experience opioid-induced respiratory depression events on the general care floor and may benefit from improved ...

The effect of patient ethnicity on the accuracy of peripheral pulse oximetry in patients with COVID‐19 pneumonitis: a single‐centre, retrospective analysis

Anaesthesia, 2021
Pulse oximetry is used widely to titrate oxygen therapy and for triage in patients who are critically ill. However, there are concerns regarding the accuracy of pulse oximetry in patients with COVID‐19 pneumonitis and in patients who have a greater ...

Monte Carlo Analysis of Optical Interactions in Reflectance and Transmittance Finger Photoplethysmography [PDF]

, 2019
Photoplethysmography (PPG) is a non-invasive photometric technique that measures the volume changes in arterial blood. Recent studies have reported limitations in developing and optimising PPG-based sensing technologies due to unavailability of the ...

Novel Use of Home Pulse Oximetry Monitoring in COVID‐19 Patients Discharged From the Emergency Department Identifies Need for Hospitalization

Academic Emergency Medicine, 2020
Our objective was to evaluate patient‐reported oxygen saturation (SpO2) using pulse oximetry as a home monitoring tool for patients with initially nonsevere COVID‐19 to identify need for hospitalization.

Effect of using disposable polyethylene bag as a probe cover or finger cover in pulse oximetry

Journal of Family Medicine and Primary Care, 2022
Background: Consumer-grade pulse oximeters are used to monitor blood oxygen levels (SpO2) at home. Sharing a pulse oximeter with family members in isolation centers or home isolation due to COVID-19 may increase the chances of cross-infection.

OxyChip Implantation and Subsequent Electron Paramagnetic Resonance Oximetry in Human Tumors Is Safe and Feasible: First Experience in 24 Patients

Frontiers in Oncology, 2020
Introduction: Tumor hypoxia confers both a poor prognosis and increased resistance to oncologic therapies, and therefore, hypoxia modification with reliable oxygen profiling during anticancer treatment is desirable.
