WebbRespiratory rate (RR) is a key clinical indicator but monitoring respiration can be difficult in young children. RR can be derived by low pass filtering (LPF) of pulse oximetry plethysmogram (pleth) traces in infants and children (Wertheim et al. Arch Dis Child Fetal Neonatal Ed 2009; 94:F301-F303). A plethysmograph is an instrument for measuring changes in volume within an organ or whole body (usually resulting from fluctuations in the amount of blood or air it contains). The word is derived from the Greek "plethysmos" (increasing, enlarging, becoming full), and "graphein" (to write).

Body plethysmography is safe, but deep breathing may make you feel lightheaded or dizzy. Your healthcare provider will contact you after a few days with your test results. WebbPerfusion Index or PI is the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a patient's peripheral tissue, such as finger tip, toe, or ear lobe. Perfusion index is an indication of the pulse strength at the sensor site. The PI's values range from 0.02% for very weak pulse to 20% for extremely strong pulse.
