The high rate of postnatal infant and maternal mortality in Indonesia makes the Indonesian Health Index at a low level with an average MMR of 305 per 100,000 births per year. The high MMR problem is experienced by Banyuwangi district with the highest MMR reaching 134.8 per 100,000 births per year. One of the highest causes of AKI is due to the occurrence of preeclampsia or bleeding in women giving birth. Several innovation programs to suppress MMR have been carried out, one of which is the pick-up program for sick people and pregnant women at risk which has been implemented since 2019. However, the limited equipment for examining patient data for pregnant women at risk by health workers supporting the program is limited and lacks mobility. high, so the purpose of this research is the creation of innovative equipment for supporting health workers in the form of a Mobile CTG Kit based on the Internet of Things to measure fetal heart rate activity and uterine contractions. The method used in this study is a Research and Development Product (R&D) which focuses on the production of a Mobile CTG Kit equipped with Piezoelectric and Electromyography (EMG) sensors to measure the fetal heart rate and uterine contractions, respectively. The sensor measurement results are then calibrated by comparing them with existing equipment in the hospital. The measurement results using the two sensors still have a large error range of around 5%, so research is still needed regarding the calibration method of sensor readings in order to obtain the same performance but at a more affordable price with the actual equipment in the hospital.

Fuzzy neural networks have been widely applied in the medical field. In this paper, we apply cascade architectures of fuzzy neural networks to monitoring fetal health using Cardiotocography data. Cascade architectures of neural networks can select reduced size of input subspace by selecting useful inputs. For the optimization of the input subspace and the structure of the cascade architectures of fuzzy neural networks, genetic algorithms and gradient decent method are used. To verify the applicability of the proposed method, Cardiotocography data available on the Machine Learning Repository site at the University of California at Irvine is used. [ABSTRACT FROM AUTHOR]

Electronic fetal heart rate (FHR) recording is a standard way of monitoring fetal health in labor. Decelerations and accelerations usually indicate fetal distress and normality respectively. But one type of acceleration may differ, namely an overshoot that may atypically reflect fetal stress. Here we describe a new method for detecting decelerations, accelerations and overshoots as part of a novel system for computerized FHR analysis (OxSyS). There was poor agreement between clinicians when identifying these FHR features visually, which precluded setting a gold standard of interpretation. We therefore introduced 'modified' Sensitivity (SE°) and 'modified' Positive Predictive Value (PPV°) as appropriate performance measures with which the algorithm was optimized. The relation between overshoots and fetal compromise in labor was studied in 15 cases and 15 controls. Overshoots showed promise as an indicator of fetal compromise. Unlike ordinary accelerations, overshoots cannot be considered to be reassuring features of fetal health. [ABSTRACT FROM AUTHOR]

As part of the development of a low-Tc SQUID-based magnetometer system for measuring fetal heart activity, the means of cooling is evaluated. To lower the threshold for the clinical application of this fetal heart monitor, it should be simple to operate. It is, therefore, deemed necessary to replace the liquid helium by a closed-cycle refrigerator. In this paper, the requirements with respect to the cryogenic system are defined. These include operating temperature (4 K), temperature stability (<0.2 K), cooling power (>0.1 W) and requirements on magnetic and mechanical interference. The paper also reviews the most relevant options for the realization of the cryogenic system. After comparison, we selected a 4-K mechanical cooler. To reduce the interference, it is placed at several meters from the magnetometer. The cooling power is to be transferred by circulation of helium. © 2004 American Institute of Physics [ABSTRACT FROM AUTHOR]
