To characterize changes in peripheral
microcirculation, blood flow and
oxygenation following the breathing
guiding device
.
•
The dynamic behavior of peripheral
microcirculation is a marker for
physiological and pathological
conditions with diagnostic and
predictive power.
•
Transcutaneous oxygen tension
(tcPO
2
) and Laser Doppler
Flowmetry (LDF) were found as a
sensitive monitoring of tissue
oxygenation and perfusion,
respectively.
•
The RESPeRATE™ is a breathing
guiding device based on musical
tones which use clinically for
reducing hypertension.
•
Relationship between the cardio
pulmonary system and the response
of the peripheral microcirculation to
slow breathing has never been
investigated.

Background
3.1. Study population:
13 Healthy volunteers
ages 25 50, 38% women & 62% men.
3.2. Experimental Setup
•
Volunteers underwent a test, during
which the breathing rate was reduced to
5 breaths/min [bpm] using the
RESPeRATE™ device for 15 min.
•
Blood pressure (BP) was measured pre,
during and post 15 minutes breathing
training session.
•
Signals were monitored and recorded
continuously [figure. 1].
