When you asked your doctor, were you happy with your numbers? Next time rather than wonder, why not just ask the P/A to turn the monitor to where you can see for yourself what the stats are.
You could invest in yourself by buying a blood pressure tester for home use like this example.
Omron 3 Series Upper Arm Blood Pressure Monitor.
And a blood oxygen O2 tester that will give your pulse at the same time.
If you do decide to monitor your stats at home take that blood pressure tester with you the next time you visit your doctor. That way you can check what you have against what the doctors equipment shows.
