I just ordered a pulse oximeter that measure oxygen in your blood and gives your pulse. It's amazing how they're all backordered. I won't get mine until May, and that's with special priced shipping. I called Walgreens, and they have none in stock, even for prescription order.
I wonder if he had any stocks in pulseox making companies, this is just the cynical in me.
I though about getting one for myself some time ago but I gave up on that.
If you have a newer Samsung phone you can get your pulse oximetry with it, I don't know about iPhones. Likely not the most calibrated but good enough.
Every case is different. The article mentioned that if a person is getting ACE inhibitors for marginal reasons, then it might be worse. In my case, although I had triple bypass, I;ve had no heart attacks and its very strong and in good shape. It's just that my arteries were clogged. But that's been taken care of with bypass. The high blood pressure is rather mild in my case. My cardiologist likes prescribing drugs in his tool kit. But, For a change I'll listen to what he says and not second guess him like I do most experts. I've got a call out to him. Meanwhile, I'm going to wash my hands.
I have no intention on giving you medical advice on the internet (if it sounds like I'm giving medical advice, it's not my intention and you should disregard it). That and the fact that while I know a good amount about cardiology and HTN, this is mostly for inpatient and I'm not a cardiologist.
