Study Details

Study Description

Brief Summary

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

Condition or Disease Intervention/Treatment Phase

    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.
