ABSTRACT
Components of opacity pulse waves derived from the conjunctival microcirculatory bed hear a consistent relationship to events in the electrocardiogram. In general, wave contour closely resembles that of the "arterialized" venous pulse. Wave contour may change from beat to beat and is affected at least in part by the size and configuration of vessels being monitored. Variations in base line activity of continuous recordings occur (1) in concert with pressure changes in the macrocirculation during the respiratory cycle and (2) spontaneously, in no apparent relationship to phenomena of the central arterial or venous pressures. Spontaneous base line changes are sometimes observed concurrently with spontaneous vasomotion in the vascular bed. Changes in base line during respiration coinciding with changes in central arterial and venous pressures may reflect the interaction of central pressures as gross determinants of pressure gradient, blood volume and blood flow velocity in the microcirculatory bed.
