Eligibility Criteria:
Inclusion Criteria:~1. Subject is ≥ 18 years of age.~2. Subject or their legally authorized representative understands the research nature of the study and is willing and capable of providing informed consent~3. Subject has appropriate femoral arterial access~4. Subject presents with a Rutherford classification of 4 to 6.~5. Planned DSA with endovascular intervention below the knee on one or both limbs.

Subject with active atrial fibrillation at time of procedure~4. Critical limb ischemia due to acute arterial occlusion.~5. Subject with documented ejection fraction \< 40% and/or prolonged bradycardia (\< 60 beats per minute)~6. Inability to collect toe pressure on index limb from subject~7. Subjects with history of or known reaction or sensitivity to contrast agent that cannot be pre-medicated or any other condition that precludes an endovascular intervention and DSA~8. Female subject of childbearing potential who is pregnant (she must have negative pregnancy test within the 48 hours prior to enrollment), or plans a pregnancy during study period,~9. Subject life expectancy \< 3 months,~10. Subject is participating in a potentially confounding device or drug clinical trial that interferes with this study~11. Investigator considers subject to be a poor candidate for the study or believes that the patient may compromise the study, e.g., concomitant conditions (reasons will be documented) )
