Detection of Breathing and Heart Rates in UWB Radar Sensor Data Using FVPIEF-Based Two-Layer EEMD
IEEE Sensors Journal, 2019Ultra-wideband (UWB) radar is an important remote sensing tool of life detection or a non-contact monitor of the vital signals. By processing the received UWB pulse echoes reflected from the body, different signals corresponding to heart activity and ...

A Noncontact Breathing Disorder Recognition System Using 2.4-GHz Digital-IF Doppler Radar
IEEE journal of biomedical and health informatics, 2019In this paper, a noncontact breathing disorder recognition system has been proposed for identifying irregular breathing patterns. The proposed system consists of a Doppler radar-based sensor module and a machine-learning-based breathing disorder ...

Breath Characteristics of Volitional Yoga Breathing and Breath Awareness
International Journal of Yoga TherapyAbstract Changes in breathing during pranayama (yoga breathwork) are usually inferred from practice guidelines in traditional texts or contemporary writings. These changes point to understanding the effects of pranayama and indicate applications of pranayama in health. Previously, a pilot study on a single participant suggested that each

Upon rapid ascent to high altitude or acute exposure to hypoxia ventilation rises rapidly (the acute hypoxic ventilatory response, initiated by the carotid bodies containing oxygen sensors), followed immediately by a secondary roll-off that partly is caused by the hyperventilation-induced hypocapnia. When the hypoxia is sustained, ventilation starts to

Breathing is controlled by an automatic brain-stem controller acted on by higher neural influences that stabilize breathing and compensate for neuromechanical abnormalities. Loss of this wakefulness-dependent descending influences during nonrapid eye movement (NREM) sleep results in the appearance of a hypocapnic apnea threshold, which is associated ...
