Abstract
The invention relates to a probe and a method for use with a probe, which produces signals indicative of the light absorption of arterial blood at least at a first light wave-length and at a second light wavelength. In order to indicate if the probe is not properly attached to a tissue site the method comprises measuring with at a third wave-length. The third wavelength is chosen so that human tissue is less transparent than at the first and second wavelengths.
