We have used a CW imaging apparatus to measure the near infrared (NIR) optical properties of rodents in vivo. We observed changes in the tissue vasculature of the animals in response to inspiratory hypercapnia (elevated CO2) and hyperoxia (elevated O2). The dynamics were dependent upon the inspired gas concentrations.
