Neonatal pulse oximetry screening improves detecting of critical congenital heart disease

引用

Chinese Medical Journal 2013年第14期126卷 2736-2740页

作者： MA Xiao-jing HUANG Guo-ying Pediatric Heart Center Children's Hospital of Fudan University Shanghai 201102 China

Objective Life-threatening critical congenital heart disease （cCHD） is often not detected in the neonatal period. Unrecognized cCHD results in high morbidity and mortality rates. As a non-invasive, convenient, quick and accurate measuring method, pulse oximetry is considered to be a promising strategy to screen for cCHD in neonates. This article is a review on the neonatal pulse oximetry screening for cCHD. Data sources Articles on neonatal pulse oximetry screening for cCHD were accessed from PubMed, using keywords including congenital heart defects, neonatal screening and oximetry. Study selection Original articles and critical reviews selected were relevant to the review＇s theme. Results The factors in the course of implementation, including threshold for positive pulse-oximetry screening results, the pulse oximeters used, timing of the screening, and the measuring position, influence the accuracy of the screening. It is recommended that the screening is completed on the second day of life, before hospital discharge. Motion-tolerant pulse oximeters, which can also be applied to measure the saturation in Iow-perfusion conditions, should be used. The probe should be put on both the right hand and on one foot. Thresholds of 〈95% in either limb or a difference of 〉3% between the limbs as a positive result may be appropriate. It should be emphasized that pulse-oximetry screening cannot be used as the only way to detect cCHD, clinical examination is also important in this situation. Cost-benefit analysis in the United Kingdom revealed it was plausible to use pulse oximetry as an adjunct to clinical examination. However, it is still controversial as to whether pulse oximetry can be used as a routine screening method for cCHD in neonates. Conclusions Neonatal pulse oximetry screening improves detection of cCHD. Further studies should be carried out before it becomes one of the routine newborn screening programs.

The Feasibility of Flat, Portable and Wireless Device for Non-Invasive Peripheral Oxygenation Measurement over the Entire Body

引用

Journal of Biomedical Science and Engineering 2016年第3期9卷 147-159页

作者： Zehava Ovadia-Blechman Omri Gino Liron Dandeker Nadav Sheffer Erik Baltaxe Vered Aharonson Medical Engineering Department Afeka Tel-Aviv Academic College of Engineering Tel Aviv Israel Electrical Engineering Department Afeka Tel-Aviv Academic College of Engineering Tel Aviv Israel Pulmonary Diseases and Internal Medicine Institute Sheba Medical Center Tel Hashomer Israel School of Electrical and Information Engineering University of the Witwatersrand Johannesburg South Africa

Peripheral oxygenation level (SpO2) can provide vital information on body functions. Continuous monitoring facilitates effective diagnosis and treatment and can even be lifesaving. Clinical device monitor SpO2 using a clip, and measure light transmission through the tissue. This method limits the body locations of the clip’s placement and is sensitive to body movement, which hampers continuous SpO2 monitoring during wakefulness or sleep, thus decreasing its usability in clinics and its accessibility in homecare usage. We developed a portable, wireless, flat and low cost prototype for continuous monitoring of SpO2 that overcomes those limitations. The prototype enables convenient measurement in larger variety of body locations by spectrophotometric measurements of changes in the optical reflectance unlike other device that measure absorption through the tissue. The original design and signal processing enable reliable signal acquisition, synchronization and control. An Android’s application was developed to provide a user friendly interface for results display on smartphones. The prototype’s measurements were compared to commercial device that simultaneously measured heart rate frequency, transcutaneous oxygen tension (tcPO2) and SpO2. The prototype’s measurements accurately reflected changes caused by blood pulses, were correlated to the heart rate, and were sensitive to changes in oxygen saturation. Excellent real time behavior and synchronization were demonstrated between the hardware and smartphone software. Our prototype thus enables convenient SpO2 measurement over the entire body, while maintaining accuracy comparable to commercial device. Its smartphone application enables accessible and understandable results display to patients, care-givers and healthcare professionals. The application’s display and alert calibration flexibility facilitates the prototype’s usage in changing medical
