Near Infrared Spectroscopy (NIRS) for Heart Failure Assessment in the Outpatient Setting
It is routine practice for a cardiologist to perform a battery of tests to assess the degree
of heart failure. The purpose of this study is to establish a non-invasive method to
reliably predict cardiac output state in real-time in children and adolescents with heart
failure in an outpatient setting. This study will rely on the use of near infrared
spectroscopy monitors to measure cardiac output in the outpatient setting.

spectroscopy monitors to measure cardiac output in the outpatient setting.
Near-infrared spectroscopy (NIRS) technology, such as that used in pulse oximetry, has been
used in medicine for decades. Several characteristics contribute to its widespread use,
including its noninvasive nature, reliability and safety. The Somanetics' INVOS® System
harnesses this power to safely and reliably "see inside" the brain and body. NIRS devices
measure the venous weighted oxy-hemoglobin saturation (color of blue blood) in a field of
tissue, rather than in arteries, and thus the rSO2 parameter provides a window into regional
oxygen supply-demand relationships. Monitoring rSO2 at two distinct sites (cerebral and
somatic) has become common practice at our institution for all infants and children in the
intensive care unit and provides valuable feedback about potentially deleterious trends in
regional tissue oxygenation that cannot easily be obtained by other modalities in such
patients.
