Laser Doppler microscope in an oblique-backward mode and pulsatile blood flow velocity in pulmonary arteriole.
Blood flow velocity, pulsatile in correspondence to cardiac events, in pulmonary arterioles of anesthetized bullfrogs could be measured on lung surfaces covered with a water-containing plastic disc by means of a laser Droppler microscope arranged in an oblique-backward mode.
