I have patients asking me about which blood pressure monitor to buy since a lot of them have hypertension and I don’t really know much about this. They have like 10 dollar monitors from Walmart so I’m wondering what advice do I give them? Is this monitor they have accurate or do they need like a 100 dollar one? Can anyone post which one that is like less than 100 bucks hopefully I can advise them to get? Thanks for the insights.
