Rising Pressure

The first thing they do when I walk into my doctor's office is take my pulse and my blood pressure. They put the machine on me yesterday and it read my BP at 182/88. "That's kind of high, isn't it?" I asked the nurse, the concern in my voice well within reason.

"These machines are always high," she assured me, clearly lacking the concern I felt she should experience. Well, okay, but 182 over 88? "The doctor will check it again when you see him." And he did, at a much better 138/74. Not terrific, but not particularly dangerous either.

The nurse is right though: their machines do always seem to be high. I've noticed that for years at my doctor's, and my BP is always better when they measure it old school during my exams. So my question is, Why do you use such inaccurate equipment? Why bother, if you don't like the results it spits out?

The blood pressure machine I have at home (I take my own BP most mornings on my PCP's suggestion) typically has me in the 130-140 over 75 or 76 range, so I trust when he checks it the old fashioned way. But if the unit I bought at a drugstore in Cedarville, MI (my old one conked out when I was up north last year, not that that's important for you to know yet it does help pad my blog) for all of forty bucks is reasonably accurate, why can't the Detroit Medical Center find one more reliable than what it's got?

Maybe there are some questions which simply aren't answerable. Like, why can't the Cocoa Puffs bird eat his cereal in a calm, rational manner?
