Review on 📈 Monitor for Performance by Tim Crowder

I bought this to have my two children with chronic breathing problems on hand. I have a Welch Allyn Vital machine, but it's not exactly portable. It was great for checking her oxygen saturation when I'm not entirely sure if her meds are reducing it. An added bonus is that my mom can come by to check her heart rate so she can know if her atrial fibrillation is active or if she just has a rapid pulse. Anything I need to avoid unnecessary trips to the doctor or emergency room is worth a lot to me!
