Abstract and Figures

A portable mobile real time oxygen monitoring auto-ventilation system using a mobile phone, oximeter, mass gas flow controller, and a portable oxygen cylinder is proposed. The system consists of a tele-monitoring system and an oxygen tele-controller system. The tele-monitoring system consists of a mobile phone and a portable oximeter. The oximeter transmits the blood oxygen level and heart rate to the mobile phone for real time monitoring. The oxygen tele-controller consists of a mobile phone, mass gas controller, oxygen cylinder, and an oxygen mask. The mobile phone is used to control the mass gas controller to supply the patient with oxygen based on the real time monitoring values. The proposed system is designed to develop a portable mobile oxygen monitoring system for oxygen delivery at home and on the go activities for Chronic Obstructive Pulmonary Disease, Obstructive Sleep Apnea, and hypoxia related disease patients.

... When the oxygen level reduces below 90%, the patients can breathe only with the help of a mechanical ventilator or artificial ventilator [3,4]. An artificial respiration system will replace the respiratory muscles that provide the energy required during the inspiration process to ensure the flow of gas into the alveoli ducts [5]. With the help of the artificial ventilation system, the patient can breathe easily and this makes it easy for doctors to reduce the cold that has blocked the lungs. ...
Hybrid optimization techniques based automatic artificial respiration system for corona patient
Article
Full-text available
  • Apr 2022
Artificial ventilation is widely used for various respiratory problems of human beings. The oxygen level of the corona patients has to be maintained for smooth breathing which is very difficult. For achieving this state, the air pressure should be controlled in the respiration system that has a piston mechanism driven by a motor. An Automatic respiration system model is designed and controller parameters are tuned using hybrid Optimization techniques. Hybrid Controllers like genetic algorithm based Fractional Order Proportional Integral Derivative controller (FOPID), Fmincon-Pattern search Algorithm based Proportional Integral Derivative (PID) controller, and Hybrid Model predictive control (MPC) – Proportional Integral Derivative (PID) controllers were designed and verified. Integral Square Error is considered as the objective function of the optimization technique to find the controller parameters. The output responses of all three hybrid controllers are compared based on the error indices, time domain specifications, set-point tracking and Convergence speed graph. The genetic algorithm-based FOPID controller gives better results when compared with the Fmincon-Pattern search Algorithm based Proportional Integral Derivative (PID) controller and Hybrid Model predictive control (MPC) – Proportional Integral Derivative (PID) for the proposed artificial ventilation system.

Desktop based real time oxygen auto-ventilation and gas monitoring system for homecare respiratory application
Conference Paper
Full-text available
  • Sep 2014
A desktop based real time oxygen auto-ventilation and gas monitoring system is proposed for home care respiratory application. The system consists of four sub-systems: oxygen monitoring system, oxygen ventilation system, gas monitoring system, and data transfer system. An oximeter transmits arterial oxygen saturation level and heart rate to the desktop unit via Bluetooth. Based on the oxygen saturation level, a flow rate is computed on the desktop. The computed flow rate is used to regulate the supply of oxygen from the oxygen generator to the patient. In addition, the gas temperature and gas pressure is monitored in real time. The system was able to monitor the patient's oxygen saturation, patient's heart rate and the gas condition at frequency of 1 Hz. Increased heart rate and low oxygen saturations are signs of respiratory distress, which this system uses to prompt oxygen flow. By matching oxygen supply to clinical need, the system has the potential to improve the home care and quality of life of patients with chronic respiratory disorders who are frequent desktop users.

Design and Fabrication of Automatic Oxygen Flow Controller for COVID Patient
Chapter
  • Jan 2022
In this ongoing pandemic situation, an acute shortage of oxygen due to number of patients required the pure oxygen supply becoming high, showed us the level of importance of this gas. People getting affected by COVID-19 are suffering from low saturation level which needs to be increased by the supply of pure oxygen. The oxygen is used to bring the saturation level to 94%. Any drop below 84% lead to serious respiratory failures. We propose a system where the oxygen is supplied to the patient as per the requirement preventing the wastage of oxygen. This is done by constantly monitoring the oxygen level of the patient and releasing the exact amount of oxygen needed by the patient, using a microcontroller device, to control the flow rate of oxygen. This helps automatically to control the oxygen flow and also alert the doctor if the patient goes into a critical condition.KeywordsOxygenSaturation levelOximetryMonitoring vitalsAlert notifications

Robust Blind Source Separation of Maternal and Fetal ECG Signals—Application to Instantaneous Heart Rate Calculation
Chapter
Full-text available
  • Jan 2022
Blind Source Separation approaches have proved their efficiency to solve problems dealing with recovering a set of underlying sources from recoded observations without any a priori knowledge on the mixture process and sources. For this reason, we propose to use them to extract the true fetal ECG signal and consequently to calculate its instantaneous heart rate. Thus, we aim the application of the Robust Second-Order Blind Identification (RSOBI) algorithm, which exploits non-stationarity properties and second-order statistics, to a set of ECG mixtures recorded on pregnant mother. The obtained results show that we can separate original mixtures into 3 main sources which can be considered as the fetal ECG, the maternal ECG and noise. The recovered fetal ECG signals were found very clean and have permitted to perform fetal instantaneous heart rate calculation with a high precision.KeywordsBlind source separationFetal ECGInstantaneous heart rateRSOBI

A home remote mobile monitoring system for long-term oxygen therapy for chronic obstructive pulmonary disease management
Conference Paper
Full-text available
  • Nov 2015
Clinicians lack in robust continuous measurements on important aspects of prescribed home long-term oxygen therapy (LTOT) for chronic obstructive pulmonary disease (COPD) such as the usage and the wellbeing of the patient whilst using the machine. Consequently, it is challenging to objectively determine if LTOT is beneficial for the patient but also to recognize whether a hospital readmission is likely attributable to physical or psychological changes. This paper presents a solution to this unmet need by designing and conceptually creating a remote system prototype that continuously records the oxygen flow rate, oxygen saturations, physical activity, sleep quality, the risk of a pulmonary exacerbation and the level of anxiety and depression to a secured database that can be accessed remotely from a smartphone. The importance of the proposed system is to further understand the effect of LTOT in the patient's routine but also to lay the foundation for personalized LTOT.

Sleep Apnea Monitoring using mobile phones
Conference Paper
Full-text available
  • Oct 2012
Obstructive Sleep Apnea (OSA) is a sleeping disorder characterized by the repetitive reduction of airflow during sleep. In this paper, we discuss the design and implementation of a user-friendly mobile application developed on multiple platforms (Windows and Android) to monitor and detect symptoms of sleep apnea using the smart phone's built-in sensors. The purpose of the application, Sleep Apnea Monitor (SAM), is to allow users to get a sense of whether or not they are likely to have sleep apnea, before continuing with more expensive and advanced sleep tests. In addition, SAM provides doctors and sleep specialists with remote access to patients' records and allows them to confirm their initial diagnosis. The parameters measured by this application are breathing patterns and movement patterns, which are recorded respectively using the built-in microphone and accelerometer. The recorded data is sent to a server for analysis in order to diagnose patients and maintain geographical studies of areas with sleep apnea patterns. The application is successfully tested among a number of users in the UAE. The system diagnoses and reports the level of the user's sleep apnea. In addition, doctors can remotely monitor users through the website, which is interfaced with Google Maps to keep track of user locations, and keep track of their analysed records.

Epidemiology of Obstructive Sleep Apnea: a Population-based Perspective
Article
Full-text available
This review summarizes the recent literature on the epidemiology of adult obstructive sleep apnea (OSA) from various population-based studies. Despite methodologic differences, comparisons have yielded similar prevalence rates of the OSA syndrome in various geographic regions and amongst a number of ethnic groups. Risk factors for OSA including obesity, aging, gender, menopause, and ethnicity are analyzed. We also provide discussion on adverse medical conditions associated with OSA including hypertension, stroke, congestive heart failure, coronary artery disease, cardiovascular mortality, insulin resistance, and neurocognitive dysfunction. Finally with the progression of the global obesity epidemic, we focus on the economic health care burden of OSA and the importance of recognizing the largely undiagnosed OSA population with emphasis on strategies to improve access to diagnostic resources.

Obstructive sleep apnoea and obesity
Article
Background: Obstructive sleep apnoea (OSA) and obesity are two common conditions affecting the Australian population; obesity is the major risk factor for OSA. Objective: The objectives of this article are to review the interactions between obesity and OSA, including the increased cardiovascular risk, and highlight the importance of using OSA diagnosis as a critical time to address obesity itself and other cardiovascular risk factors. Discussion: Snoring and symptoms of OSA frequently worsen during periods of rapid weight gain. Obesity and metabolic factors (eg hypertension, hyperlipidaemia, insulin resistance) are commonly present at the time of OSA diagnosis. Severe OSA is an independent risk factor for cardiovascular disease and stroke. Continuous positive airway pressure (CPAP) treatment is safe and effective, reduces sleepiness, and improves mood and quality of life; however, the cardiovascular benefits of CPAP are uncertain. Weight loss leads to variable improvement in OSA, is most effective in milder OSA, and has a greater benefit on cardiovascular risk than CPAP.

Real-Time Monitoring of Respiratory Diseases of Distantly Located Elderly Impaired Patients
Conference Paper
  • Dec 2012
This paper presents a cost effective on-line ventilation monitoring system for impaired elderly persons using optical wireless sensory system. In this work, we have tried to develop this system especially for aged physically disabled people by introducing a cordless optics based sensing system as a secondary transducer which carries many distinctive features like i) no electrical signal is directly connected with the subject's body, thus providing a shock hazard free module, ii) any hardware interfacing circuit (for computer compatible signal) not required which again minimizes complex circuitry and finally generates iii) a noise free computer friendly output. The processor analyses the signal and communicates information to the distantly located physicians through blue tooth technology. Here, we have developed an algorithm which monitors important spirometric values such as Forced Expiratory Volume of air in first one second (FEV1) Forced Vital Capacity (FVC) and Peak Expiratory Flow (PEF) continuously, so that any deviation from the safe limits will allow the system to send a warning sign to the physician's mobile and at the same time it will send numerical and graphical respiratory information of the subject to the web-server. Our study is limited to two common respiratory diseases like chronic obstructive pulmonary disease (COPD) and chronic restrictive pulmonary disease (CRPD). We have studied the respiratory activities of 50 male impaired elderly persons. The sent information through the wireless technology using telemetering platform was in very close agreement with the actual clinical conditions.

A mobile-health system to manage Chronic Obstructive Pulmonary Disease patients at home
Article
  • Aug 2012
Chronic Obstructive Pulmonary Disease (COPD) is a major cause of morbidity and mortality in Australia and globally, and leads to a substantial burden on healthcare services. Effective and timely management of patients with COPD has been essential to alleviate COPD exacerbation, improve the quality of life, and consequently reduce the economic burden. To achieve this, a mobile and internet technologies assisted home care model (M-COPD) was developed to assist clinicians to remotely monitor and manage COPD conditions and events. This paper will focus on the technical aspect of M-COPD system by describing its setup and discussing how the M-COPD could address the clinical needs in monitoring and managing COPD conditions of patients at home.

A Wireless Portable System With Microsensors for Monitoring Respiratory Diseases
Article
A wireless portable monitoring system for respiratory diseases using microsensors is proposed. The monitoring system consists of two sensor nodes integrating with Bluetooth transmitters that measure user's respiratory airflow, blood oxygen saturation, and body posture. The utility of micro-hot-film flow sensor makes the monitor can acquire comprehensive respiration parameters which are useful for diagnoses of obstructive sleep apnea, chronic obstructive pulmonary disease, and asthma. The system can serve as both sleep recorder and spirometer. Additionally, a mobile phone or a PC connected to the Internet serving as a monitoring and transfer terminal makes telemedicine achievable. Several experiments were conducted to verify the feasibility and effectiveness of the proposed system for monitoring and diagnosing OSA, COPD, and asthma.

Real-Time Detection of Apneas on a PDA
Article
  • Jul 2010
Patients suspected of suffering sleep apnea and hypopnea syndrome (SAHS) have to undergo sleep studies such as expensive polysomnographies to be diagnosed. Healthcare professionals are constantly looking for ways to improve the ease of diagnosis and comfort for this kind of patients as well as reducing both the number of sleep studies they need to undergo and the waiting times. Relating to this scenario, some research proposals and commercial products are appearing, but all of them record the physiological data of patients to portable devices and, in the morning, these data are loaded into hospital computers where physicians analyze them by making use of specialized software. In this paper, we present an alternative proposal that promotes not only a transmission of physiological data but also a real-time analysis of these data locally at a mobile device. For that, we have built a classifier that provides an accuracy of 93% and a receiver operating characteristic-area under the curve (ROC-AUC) of 98.5% on SpO2 signals available in the annotated Apnea-ECG Database. This local analysis allows the detection of anomalous situations as soon as they are generated. The classifier has been implemented taking into consideration the restricted resources of mobile devices.

The Medical Cost of Undiagnosed Sleep Apnea
Article
  • Oct 1999
Obstructive sleep apnea is an under-diagnosed, but common disorder with serious adverse consequences. Cost data from the year prior to the diagnosis of sleep-disordered breathing in a consecutive series of 238 cases were used to estimate the potential medical cost of undiagnosed sleep apnea and to determine the relationship between the severity of sleep-disordered breathing and the magnitude of medical costs. Among cases, mean annual medical cost prior to diagnosis was $2720 versus $1384 for age and gender matched controls (p<0.01). Regression analysis showed that the reciprocal of the apnea hypopnea index among cases was significantly related to log-transformed annual medical costs after adjusting for age, gender, and body mass index (p<0.05). We conclude that patients with undiagnosed sleep apnea had considerably higher medical costs than age and sex matched individuals and that the severity of sleep-disordered breathing was associated with the magnitude of medical costs. Using available data on the prevalence of undiagnosed moderate to severe sleep apnea in middle-aged adults, we estimate that untreated sleep apnea may cause $3.4 billion in additional medical costs in the U.S. Whether medical cost savings occur with treatment of sleep apnea remains to be determined.
