To evaluate the effects of epidural and spinal anesthesia techniques applied in cesarean section surgery on neonatal cerebral oxygenation using Near Infrared Spectroscopy (NIRS).
The goal of this is prospective cohort study is to to study the relationship between PaO2 and SpO2 in the overall population undergoing general anesthesia in the OT. Secondary aims include studying the relationship between PaO2 and SpO2 in elderly and obese patients undergoing general anesthesia in the OT, validating the derivation of PaO2 from SpO2 using formulas derived by Rice, Pandharipande, and Gadrey in patients undergoing general anesthesia in the OT, and, if the derivation formulas were not valid, to derive a formula for patients undergoing general anesthesia in the OT. The included blood samples are arterial blood sample collected for ABGs analysis through either an arterial catheter or an arterial blood puncture in adult patients (Age >18 years) undergoing general anesthesia regardless of the acuity of the surgery (elective, emergency, or lifesaving), the hemodynamic stability of the patient, or the comorbidities. Patients undergoing cardiac or thoracic surgeries will be excluded.

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.
It is important to evaluate the accuracy of the pulse oximeter, which is commonly used in clinical practice. The US FDA only allows the use of devices that meet the ISO 80601-2-61:2017 standard in the United States. According to the ISO 80601-2-61:2017 standard, the accuracy of the oxygen saturation (SpO2) of the pulse oximeter should have an error range of less than 4.0% compared to the actual arterial blood oxygen saturation (SaO2) in the range of 70-100%. To prove compliance with this requirement, it is necessary to conduct a clinical trial that induces hypoxemia in healthy adults and compares and evaluates the arterial blood oxygen saturation values of the pulse oximeter's SpO2 and the arterial blood oxygen saturation values of the carbon monoxide-oxygen meter (CO-oximeter).
The VERDICT-2 verification study will examine the accuracy of the Cloud DX Vitaliti Continuous Vital Signs Monitor (Model: CVSM-1A) in an ambulatory context with healthy participants. The objective is to determine the accuracy of continuous non-invasive vital signs metrics including respiration, pulse rate, oxyhemoglobin saturation (SpO2), core temperature, heart rate, and cNIBP against standard comparator devices guided by consensus standards.
Pulse oximeters are common medical devices used to measure blood oxygen saturation (SpO2). These devices are either stand-alone or integrated into physiologic monitoring systems, using 2 wavelengths of light to determine SpO2. With recent advances in technology, Spatial Frequency Domain Imaging (SFDI) uses a range of light wavelengths from red to near-infrared (NIR), and smartphones such as Apple Watch, and transcutaneous oximetry TCOM now have pulse oximetry capabilities. Since it is possible that most patients could utilize this technology, we sought to assess the accuracy, reliability, and usability of these oximeters and compare outcomes. In this study, a cohort of 20 healthy volunteers above the age of 18 including males and females of different skin colors will be assessed at the same site and data will be compared. We aim to provide a set of data that will support the clinical and scientific community and identify more than one reliable skin oxygen measurement modality.
Healthcare systems around the world have been dealing with COVID 19. One of the main manifestations of this infection is lung involvement of varying degrees, causing a spectrum of diseases from mild lower respiratory tract infection to severe Adult Respiratory Distress Syndrome (ARDS). One of the important clinical parameters is to detect hypoxia early in order to initiate a higher level of care at the earliest. The presence of silent or latent hypoxia has made this task difficult in COVID 19. Besides, critical findings such as silent hypoxia that is not at rest but triggered by effort can be revealed by some practical field tests such as the 6-minute walk test or the 1-minute chair sit and stand test. Moreover, these simple tools also help to investigate the patient's readiness for discharge. In this way, it will be useful to evaluate their usability in discharge decisions or in determining the post-discharge cardiopulmonary reserves of the patients and therefore their rehabilitation needs. Although walk and performance tests can be performed naturally, safely and simply, more similarly to movements in daily living activities compared to cardiopulmonary exercise tests, the interest in these tests has increased over the years, especially in subjects such as exercise capacity, mortality and morbidity expectation, or oxygen desaturation in patients with chronic cardiopulmonary pathology. The number of studies in 19 patients is quite limited. For this reason, the necessity of new studies on different field tests to detect the presence of latent hypoxia, which expresses the oxygen desaturation triggered by effort, and to evaluate the exercise tolerance status before discharge, has been emphasized in recent reviews.The aim of this study is to determine the presence of silent hypoxia, which expresses the oxygen desaturation triggered by effort, in Covid-19 patients and to compare the different short-term walk and performance tests, which the investigators consider easier and applicable in the conditions of the pandemic environment, with the classical gold standard test ( Six minute walk test) in order to evaluate the exercise tolerance status of the patients before discharge.
The research was planned in a randomized controlled experimental design to determine the effects of the cup and bottle used during the first oral feeding on physiological characteristics and feeding performance in preterm infants. The research was carried out between January 2021 and February 2022 at the Neonatal Intensive Care Unit of Göztepe Süleyman Yalçın City Hospital. Research data were obtained from preterm infants who were born before 34 weeks of gestation, appropriate to selection of study group criterias and hospitalized in the neonatal intensive care unit. A total of 80 babies in the sample group were randomly assigned to the experimental (bottle) and control (cup) groups. Oxygen saturation, heart rate, feeding performance and test weight before, during and after feeding of preterms in both groups were compared. There was no statistically significantly difference between the experimental and control groups in terms of oxygen saturation and heart rate.
