Figure 1From: Algorithm for identifying and separating beats from arterial pulse recordsTypical dc plethysmographic record of an occlusive maneuver. Insets show expanded pulses during each stage; differences are evident. An arbitrary zero time is also showed from which the pre-inflation time was measured (PRE); thereafter, the intra-occlusion (INTRA) period followed (bounded by the beginning and end of inflation), until post-occlusion was reached (POST).Back to article page
