Abstract

Holter-type devices with sets of sensors, enabling long-term measurement of quantitative respiratory parameters, were designed and constructed. Pneumonitor 2 was intended for physiologic and athletic applications, and Pneumonitor 3 for sleep studies. Both allow simultaneous, comfortable, ambulatory monitoring of cardiorespiratory activity, such as ECG, impedance pneumography (IP), and motion; the second device also allows pulse oximetry and uses improved setting with combined receiving ECG and IP electrodes. Preliminary results showed that our prototypes provide signals reliable to monitor heart and breathing activity quantitatively. We tested the devices in different conditions, including walking, stair-climbing, cycle ergometer training, natural daily activity, and sleep. They can quantitatively measure respiratory flows, volumes, and minute ventilation using IP after calibration. They are also able to estimate tachogram from ECG. They allow the detection of subject activity and body position via accelerometer and gyroscope, which is helpful during IP calibration and interpretation. Pneumonitor 3 also enables measurement of blood saturation with a pulse wave (pulse oximetry).
