Brief summary

to detect the relation between results of the peripheral perfusion index and modified Allen's test.

Detailed description

The modified Allen's test (MAT) is commonly used to assess hand perfusion. Other non-invasive methods including plethysmography, pulse oximetry and duplex ultrasonography are used nowadays. The perfusion index is calculated as the ratio of the pulsatile blood flow to non- pulsatile blood flow in peripheral tissue. In this study, we will try to detect the relation between results of the peripheral perfusion index and modified Allen's test.
