Can I use a pulse oximeter on any finger?
我可以在任何手指上使用脉搏血氧仪吗？
Although the pulse oximeter can technically be used on any finger, it's typically recommended to use it on the index or middle finger for most accurate results. The ring finger and little finger can be used but are typically less reliable.
尽管从技术上讲，脉搏血氧计可以在任何手指上使用，但通常建议在食指或中指上使用，以获得最准确的结果。可以使用无名指和小指，但通常不太可靠。
