This paper describes a system of systems for health care of elderly. The system consists of three systems: one is the system that detects heart rate and it provides the condition of autonomous nerve system. The second one is the system detecting respiration. Third one is the system detecting cough with phlegm to suction. In them we empty non-contacted three senors such as an ultrasonic oscillosensor...
Measurement of blood flow velocity using Doppler ultrasound has become an important noninvasive tool not only in the diagnosis of cardiovascular disease but also in physiological measurement. Physiological blood flow velocities in common carotid artery (CCA) is altered markedly with advancing age. It is unknown that regular aerobic exercise training can alter and improve blood flow velocity waveforms...
The purpose of this study was to measure blood flow velocities in carotid, brachial and femoral arteries simultaneously during passive postural change using our developed telemetry measurement system. This system was implemented with synchronized measurement of electrocardiogram (ECG). The velocity waveforms and ECG were continuously measured in six putatively healthy young subjects for 130 s during...
The present study aimed to investigate non-invasively the effects of a short-term 4 week aerobic training program on the resting common carotid artery (CCA) blood flow velocity waveforms and autonomic nervous activity in young sedentary healthy subjects. It was hypothesis that training-induced the enhancement of blood flow is associated with the improvement of autonomic nervous function. The CCA blood...
