Abstract

The oxygenation status of isolated hearts has often been measured using optical detection methods for the visible range of the spectrum (Tamura et al., 1989). To the best of our knowledge there are no reports on measurement of myoglobin oxygenation using detection methods in the near-infrared region of the spectrum. On the other hand, equipment for near-infrared measurements on tissue is widely available and is in some instances quite inexpensive. Therefore we investigated in the present study whether near-infrared (NIR) detection at two wavelengths provides a way to conveniently determine myoglobin oxygenation in an isolated organ as small as the saline-perfused rat heart.
