Abstract:
In the last years stress has become one of the most serious health problems in industrialized western countries. It is one of the most common reasons for a number of serious diseases and an important factor for increasing cost in health systems. Beside this, over the last years there has been an increasing interest in finding new methods for capturing psychological, behavioral and physiological data in real-time using infield data acquisition systems. Within our research group a system for ambulatory assessment of psycho-physiological signals for real-time data capture was developed. Because of the multivarious influences of stress on the physiological response of the body, a stress measurement system has to take into account as many parameters as possible. Pulse transit time (PTT) gives comprehensive information about the cardiovascular system. It is determined by measuring the ECG and the pulse wave; the latter is noninvasively measured either on a finger or on an earlobe. In a further study we discovered a strong correlation between stress and PTT and that PTT is an appropriate parameter for stress measurement. The paper describes the use of a mobile PTT-measurement system for monitoring stress in everyday life.
