Filter by:The aim of this study was to determine the effect of shellac nail polish application on pulse oximetry measurements in healthy subjects. This study was planned as a prospective, self-controlled clinical research to determine the effect of shellac nail polish application on SpO2 and pulse values in healthy people. The population of the study will consist of women who had shellac nail polish application in a private beauty centre between June 2023 and December 2023. The minimum required sample size was calculated as 162 in G*Power (3.1.9.2) programme (α=0.05 (two-way), 1-β=0.95). The data will be collected with the data collection form prepared in line with the literature. Firstly, the personal information of the participants will be recorded in the data collection form. The middle finger of the left hand of each participant will be the treatment group and the little finger will be the control group. After the shellac nail polish is applied to the middle finger of the left hand, SpO2 and pulse values will be measured simultaneously with a pulse oximeter from the left hand middle finger and little finger of the participant and recorded on the data form. The data obtained from the study will be analysed using SPSS (Statistical Package for Social Sciences) for Windows 26.0 software.
The aim of this study was to determine the effect of gel nail application on pulse oximetry measurements in healthy subjects. This study was planned as a prospective, self-controlled clinical research to determine the effect of gel nail application on SpO2 and pulse values in healthy people. The population of the study will consist of women who had gel nail application in a private beauty centre between July 2023 and October 2023. The minimum required sample size was calculated as 162 in G*Power (3.1.9.2) programme (α=0.05 (two-way), 1-β=0.95).

Purpose: Investigate the safe wearability and basic functionality - epidermal melanin concentration and blood oxygen estimation - of our developed device: Melanin-Adjusted Blood Oxygen Sensor (MABOS) Participants: Healthy adults 18-65 years of age Procedures (methods): The investigators plan to enroll 12 healthy adult participants for the study. The investigators aim to enroll 4 participants with skin tones associated with those of African descent (Group A), 4 of East Asian descent (Group B), and 4 of European descent (Group C). Additionally, the investigators aim to ensure half of group is male, and the other half female. For the duration of the study, two wearable devices will be placed on the participant: a Nonin PureSat pulse oximeter on a forefinger, and the novel wearable pulse oximeter - MABOS - on the other forefinger. Prior to testing, an Ocean HR2 XR Spectrometer will be used to assess the absorbance of three wavelengths of light - 410, 660, 940 nm - on each patient's inner wrist. Following this, the two devices will be placed on the patient, set up, and calibrated for 10 minutes. During the calibration period, MABOS will be used to measure the same three wavelengths of light utilized by the Ocean HR2 XR Spectrometer (410, 660, and 940 nm). After the calibration period, all participants will be asked to perform the following procedure 5 times as part of the testing period: a deep inhalation lasting no longer than 10 seconds, followed by a slow exhalation lasting no longer than 30 seconds. Between each trial, a five-minute break will be required. For the entire testing period, all two devices will be continuously acquiring data. After this testing period, all two devices will continue taking measurements until 90 minutes have elapsed. Skin integrity will be examined before spectrometer use, after spectrometer use, after the calibration period, every 30 minutes after the start of the testing period, and after the testing period. During the study, if the participants report any uncomfortable feeling and/or pain or if a change to the skin at the site of device placement occurs, the measurements will be discontinued, and all the devices placed on the participants will be removed. Questionnaires will be provided after the study period and during follow-up visits approximately 48 hours and 96 hours post the device testing visit for a proof-of-concept evaluation of the safe wearability.
The vital signs (pulse, systolic and diastolic blood pressure, respiratory rate, oxygen saturation and body temperature) are critical in assessing the severity and prognosis of infections. The devices used today for measuring the vital signs have to be in physical contact with the patients. There is an apparent risk of transferring infections from one patient to the next (or to healthcare professionals). Accurately obtaining vital signs is also important when managing other categories of patients where it may be relevant to obtain some of the vital signs such as pulse and blood pressure. This project aims to evaluate a new camera-based system for contactless measurement of vital signs.
This is a cross-sectional diagnostic study. In this study, wrist oxygen saturation (SwO2) will be measured by Huami smart wearable device, SpO2 of pulse oxygen saturation monitor with medical device registration certificate and SaO2 of arterial blood gas analysis will be used as reference values. A total of 180 group data will be measured in 30~50 patients with SaO2/ SpO2 between 80%∽100%. The investigators aim to evaluate the accuracy of blood oxygen saturation detection function of huami smart wearable device.
Our objective is to evaluate the influence of inhaled NO on the saturation and exercise capacity of patients with COPD and IPF. each participant will undergo two six minute walk tests, one with inhaled NO and the other with placebo.
This is an observational, cohort-based, single-site, prospective study conducted in accordance with ISO 14155-1:2003 and ISO 14155-1:2011. The primary objectives are to evaluate the accuracy of the device's measurements/readings in comparison to a gold standard or standard of care patient monitor.
