Abstract The aim of our study is to asses the efficiency of pulse oximeter as a screening tool of peripheral arterial disease. -Our study enrolled 150 patients, 50 patients above age of 60 year without symptoms of PVD, 50 asymptomatic patients with low ABI and 50 patients having symptomatic PVD. -Duplex study of lower limbs, ABI measurement and oxygen saturation difference between index finger and toe were done to every patient. -We considered abnormal pulse oximerter of the toes as a SaO2 value of more than 2% lower than the fingers value or a decrease of more than 2% on elevation of the leg (decrease from the value at the supine position), abnormal ABI < 0.9. -We found good correlation between pulse oximerter result and ABI as it can detect (82.8%) of diseased limbs detected by ABI and (86.7%) of normal limbs detected by ABI. -Pulse oximerter seems to be valuable since it can be performed in outpatient clinics and handle large numbers of patients in a short time and avoid the problem of media sclerosis. -We found that pulse oximeter was highly sensitive (85%) to detect lower limb ischemia detected by duplex also it was highly specific (96.4%) to exclude lower limb ischemia excluded by duplex. |
