new approach to carbon monoxide poisoning treatment based on laser-induced photodissociation of the carboxyhemoglobin is proposed. Using the simple model of laser tissue interaction the action spectra of laser radiation on carboxyhemoglobin of cutaneous blood vessels has been calculated. The results of calculations indicate that there is a respectively narrow spectral range in a visible region were one could effectively irradiate carboxyhemoglobin through the tissue not in a deep distances. In the case of deeper penetration the action spectra of laser radiation shifts toward the longer wavelength region. Despite of similarity of carboxyhemoglobin and oxyhemoglobin action spectrum, significant difference on quantum yields of photodissociation makes possible to develop effective method of carbon monoxide poisoning treatment.
