The arteria dorsalis pedis, when clearly palpable, is a suitable artery for direct arterial blood pressure monitoring. The systolic pressure and the pulse pressure are likely higher in the dorsalis pedis artery when compared to the radial artery but there is no clinically significant difference in mean pressures. In plethysmographic studies it was found that in 16 per cent of the patients examined the pulse in the second toe disappeared after occlusion of the dorsalis pedis artery indicating that it carried the main blood supply to the toes. Although no complications have resulted from cannulation of the dorsalis pedis artery in our practise, some caution is in order and preliminary testing may be advisable even if the posterior tibial artery is distinctly palpable.
足背动脉在能清晰触及时，是适合直接进行动脉血压监测的动脉。与桡动脉相比，足背动脉的收缩压和脉压可能更高，但平均压力在临床上无显著差异。在体积描记法研究中发现，在接受检查的患者中，16%的患者在足背动脉闭塞后第二趾的脉搏消失，这表明该动脉为脚趾提供主要血液供应。尽管在我们的实践中，经足背动脉插管未引发并发症，但仍需谨慎，即便胫后动脉能明显触及，进行初步测试也可能是明智的。
