[Should Allen test be performed before radial artery cannulation?]
The Allen test is performed to assess the circulation of the hand. It's reliability has been questioned in several studies. The results of a review are reported: the criteria of an abnormal Allen test are not agreed on and performing it cannot be considered standard care.

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
