Respiratory Monitoring System Based on the Thoracic Expansion Measurement (original) (raw)

Automatic non-contact monitoring of the respiratory rate of neonates using a structured light camera

2020 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC)

This paper introduces an automatic non-contact monitoring method for measuring the respiratory rate of neonates using a structured light camera. The current monitoring bears several issues causing pressure marks, skin irritations and eczema. A structured light camera provides distance data. Our non-contact approach detects the thorax area automatically using a plane segmentation and calculates the respiratory rate from the movement of the thorax. Our method was tested and validated using the baby simulator SimBaby by Laerdal. We used different breathing rates corresponding to preterm neonates, mature neonates and babies aged up to nine months as well as two different breathing modes with differing breathing strokes. Furthermore, measurements were taken of two positions: the baby lying on its back and on its stomach.

State-of-the-Art Sensor Technology in Spain: Invasive and Non-Invasive Techniques for Monitoring Respiratory Variables

Sensors, 2010

The interest in measuring physiological parameters (especially arterial blood gases) has grown progressively in parallel to the development of new technologies. Physiological parameters were first measured invasively and at discrete time points; however, it was clearly desirable to measure them continuously and non-invasively. The development of intensive care units promoted the use of ventilators via oral intubation ventilators via oral intubation and mechanical respiratory variables were progressively studied. Later, the knowledge gained in the hospital was applied to out-of-hospital management. In the present paper we review the invasive and non-invasive techniques for monitoring respiratory variables.

Innovative Design for Monitoring of Neonates Using Reflectance Pulse Oximeter

2011 Seventh International Conference on Intelligent Environments, 2011

Critically ill prematurely born babies admitted at the neonatal intensive care unit (NICU) have to be monitored constantly. The saturation of the peripheral oxygen (SPO2) is one of the crucial monitoring parameters on these babies. It is necessary that these fragile neonates feel most comfortable as possible during the monitoring. The current solutions for these SPO2 oximeters can be uncomfortable for use and hampers parent-child interaction. In this paper we propose an innovative solution for reflectance pulse oximeter based on Near Infrared Spectroscopy (NIRS) techniques that will lead into more comfortable use in a long term monitoring. Prototypes with the reflectance sensors embedded in soft foam and fabric materials are built to enhance a comfortable non-invasive yet reliable monitoring. These monitoring units give the opportunity of integration into a snuggle and mattress where the baby lays on most of the time. In this paper we report the integration of the prototype monitoring units into a snuggle. To evaluate the comfort as well as performance of the final prototype, we first conduct tests on adults. The prototype monitoring units are tested on various body locations of adult participants. Signal quality on different body locations is reported and questionnaires for comfort assessment are analyzed. Experiments on the premature babies will be carried out at

Automated Non-Contact Respiratory Rate Monitoring of Neonates Based on Synchronous Evaluation of a 3D Time-of-Flight Camera and a Microwave Interferometric Radar Sensor

Sensors, 2021

This paper introduces an automatic non-contact monitoring method based on the synchronous evaluation of a 3D time-of-flight (ToF) camera and a microwave interferometric radar sensor for measuring the respiratory rate of neonates. The current monitoring on the Neonatal Intensive Care Unit (NICU) has several issues which can cause pressure marks, skin irritations and eczema. To minimize these risks, a non-contact system made up of a 3D time-of-flight camera and a microwave interferometric radar sensor is presented. The 3D time-of-flight camera delivers 3D point clouds which can be used to calculate the change in distance of the moving chest and from it the respiratory rate. The disadvantage of the ToF camera is that the heartbeat cannot be determined. The microwave interferometric radar sensor determines the change in displacement caused by the respiration and is even capable of measuring the small superimposed movements due to the heartbeat. The radar sensor is very sensitive towards...

Medical Devices for Measuring Respiratory Rate in Children: a Review

Journal of Advances in Biomedical Engineering and Technology, 2016

s: Respiratory rate is an important vital sign used for diagnosing illnesses in children as well as prioritising patient care. All children presenting acutely to hospital should have a respiratory rate measured as part of their initial and ongoing assessment. However measuring the respiratory rate remains a subjective assessment and in children can be liable to measurement error especially if the child is uncooperative. Devices to measure respiratory rate exist but many provide only an estimate of respiratory rate due to the associated methodological complexities. Some devices are used within the intensive care, post-operative or more specialised investigatory settings none however have made their way into the everyday clinical setting. A non-contact device may be better tolerated in children and not cause undue stress distorting the measurement. Further validation and adaption to the acute clinical setting is needed before such devices can supersede current methods.

Monitor of respiratory movement and caretaking system in baby cradle

The paper introduces a helping hand for the busy professional parent. Parent of an infant is a responsible task. We are introducing an embedded system in the baby cradle that acts as a helping hand to nurture our next generation. With minimal effort, it creates a worriless and affectionate bond between the two while the parent is busy with professional work. The system pampers the baby and alerts the parent at the time baby cries. ARM7 microcontroller based system along with servomotor and MP3 module pampers the baby, the sound sensor detects when the baby cries, the pressure sensor detects the presence of a baby in the cradle, accelerometer sensor module takes a reading of cradle swing, the ultrasonic sensor senses the breathing movement during baby sleep time. All the collected data in CSV format get transferred to PC/laptop that can be stored to analyze baby sleep hours or how often the baby needs attention or can help to the pediatrician to diagnose some kind of disease.
