MEDAC
SYSTEM/3 SOFTWARE AND SPECIFICATIONS
SOFTWARE
- Features the
Brief Physiological Stress Profile and User Defined
Profiling for standardized assessment of autonomic nervous system
(ANS) and skeletal muscle reactivity.
- Easy to use
Protocol Manager saves general or patient specific procedures.
- Report Generator
produces graphs and tables for all physiological monitoring and biofeedback
sessions, including mean, standard deviation, min/max, and detailed
data.
INSTRUMENTATION
- Photoplethysmograph
(PPG) monitors the blood volume pulse wave for tracking heart rate and
relative changes in peripheral blood flow (pulse height).
- Two or four
channels of surface EMG (Muscle activity) using the Active Electrode,
a wide-band preamplified sensor that removes artifact and may be used
without gel.
- Two / Three
channels of DC measures (TEMP & RESP) for any combination of skin
temperature and respiration.
- Electrodermal
Activity - Skin Conductance Level (SCL) and Response (SCR).
