1.11.2 Biofeedback System Solutions for Clinical, Home,
and Outdoor Health Monitoring
The demographic changes in most industrialized countries lead to new strategies in
the health system. Therefore, all of us are encouraged to assume a more active role
into prevention, stress reduction with endogenous and/or active exercises, training,
early therapy and rehabilitation. PPG and other non-invasive sensor concepts and
portable 24/7 biofeedback systems may take over a private role responsible even
for monitoring vital body signs supplying support and alarming in extreme physical or mental stress or times of crises [60]. With user feedback, e.g., in form of a
mobile phone, a technological/biological regulation loop will be realized whereby
the subject/patient will be trained to manage vegetative functions to reduce stress
and to follow telemedical support in case of emergency (see also Chap. 4).
1.11.3 Photoplethysmographic System Solutions
for Sustainable Biomedical Care
Diagnostic measuring methods based on biomedical technology are in widespread
use today, typically involving patients’ visits to a doctor or a hospital, where measurements are then made. However, in certain circumstances, patients are too far away
from the required facilities—be it while traveling in remote regions, or even inside
an orbiting spaceship.
A range of sustainable sensor concepts, systems solutions, and procedures—some
already on the brink of clinical implementation—have been developed for such situations. For this purpose PPG is a simple in use and basically low-cost modality that
can be used for long-term monitoring of patients with cardiovascular risk by their
outdoor and working activities also via telemedical channel. If needed, a doctor can
establish contact with patients to guide them through a ‘cinematographic’ recording
of the relevant parameters, inform them about their condition, suggest appropriate
measures, or dispatch on-site medical assistance, such as the well-known Flying
Doctors in Australia.
1.11.4 Advanced Examination Strategies for Venous
Saturation Detection and Arterio-Venous Oxygen
Consumption
The photoplethysmographic detection of peripheral arterial oxygen saturation (pulse
oximetry) has become one of the established and well-proven methods in the monitoring of adults and children and is clinically used daily. The oxygen saturation
indicates what percentage of the total hemoglobin is loaded with oxygen in the
