blackdragonfly 7 Posts Nov 14, 2008 I'm a cna in a LTC facility, and they allow us to use the digital wrist cuff. In fact a lot of us have our own that we use. I work with the same residents every day so I'm familiar with their vitals. If I get a reading that may seem a bit off I'll take it again. The digital is a timesaver especially when there are 2 CNAs for the 22 residents on my hall! And our O2 sat monitors are always in use or you can't find them when you need them! That's next on my list to buy but those are a bit more pricier.
