SensiLase PAD-IQ

PAD-IQ Logo 2013

Segmental Skin Perfusion Pressure

  • Fully automated and quantitative evaluation of microcirculatory perfusion in the skin
  • Multiple levels can be assessed on limbs; bilateral measurement helps to manage test time
  • Not susceptible to interference effects from medial calcification
  • Requires use of pressure cuffs to occlude blood flow for specified time period in order to evaluate reactive hyperemic response to controlled release of pressure
  • Graphical output of pressure and perfusion during cuff deflation indicates the pressure (mmHg) at which skin perfusion is found to return in addition to pressure contour

Pulse Volume Recording (segmental volume plethysmography)

  • Shows  variations in the volume of blood passing through a limb during each cardiac cycle
  • Multiple levels can be assessed on limbs
  • Not susceptible to interference effects from medial calcification

The ABI test uses Doppler-acquired pressures

  • Data capture for posterior tibial, dorsalis pedis and brachial arteries
  • PAD-IQ can be used to automatically fill and empty pressure cuffs to assist in acquiring pressure values (mmHg)
  • PAD-IQ automatically calculates right and left ABI  to streamline process specified by CPT Codes 93922/93923

  • Segmental Skin Perfusion Pressure

    The SPP test measures skin perfusion using a laser Doppler sensor and a pressure cuff to evaluate reactive hyperemia. This type of provocative functional maneuver requires that the pressure cuff is first automatically inflated to occlude arterial bed blood flow; this is verified by the SensiLase PAD-IQ which determines that perfusion has stopped. The pressure is then automatically released at a controlled rate while the cuff pressure and skin perfusion are measured. A graph displays pressure and perfusion during cuff deflation and indicates the pressure at which skin perfusion is found to return. Additional information observable from the graph includes percentage perfusion increase above baseline, total response time, perfusion reappearance time, and perfusion contour.
  • Pulse Volume Recording

    The PVR test measures and displays a waveform representing variations in the volume of blood passing through a limb during each cardiac cycle. The PVR test is fully automated and uses a partially inflated pressure cuff to apply slight pressure to the limb. The impact of blood passing through the limb is transferred to the pressure cuff where it is measured as small changes in cuff pressure. The changes are displayed as a PVR waveform.
  • ABI Calculation

    The PAD-IQ can be used to fill and empty pressure cuffs to assist in acquiring pressure values for calculating ankle brachial index (ABI). ABI can be useful in providing an indication of PAD depending on both the methodology and technology used to detect the return of arterial pressure following controlled occlusion and release of arterial flow. Note: PAD-IQ supports Doppler-based ABI systems only since the changes made in the 2011 CPT Code language specifically require independent assessment and documentation of the pressures at the Dorsalis Pedis, Posterior Tibial and Brachial arteries.
