DUO Use
Electrodes
DUO can be used on various locations and
orientations of the chest. Each position will produce a
unique heart sound and ECG tracing.
PCG
Capture sounds by placing DUO anywhere on the
body. For best audio, press the device firmly against
Diaphragm
the skin to ensure good contact.
ECG
Capture ECG by placing and orienting DUO on the
chest. The optimal position to capture ECG data is at
an inward-facing 45° angle at the upper left pectoral
below the clavicle. If the patient has particularly dry
skin, body fat or hair, conductive gel used with other
ECG systems may be used to improve the quality of
the data.
