You’re running a trauma activation, and everything is going great! Primary survey – passed. Resuscitation – lines in, fluid going. You are well into the exam in the secondary survey.
Then it happens. The automated blood pressure cuff shows a pressure of 72/44. But the patient looks so good!
You recycle the cuff. A minute passes and another low pressure is noted, 80/52. You move the cuff to the other arm. Xray comes in to take some pictures. You roll the patient. 76/50. Well, you say, they were lying on the cuff. Recycle it again.
A minute later, the pressure is 56/40, and the patient looks gray and is very confused and diaphoretic. It’s real! But how long as it been real? An easy 5 minutes have passed since the first bad reading.
Bottom line: Sometimes it’s just hard to believe that your patient is hypotensive. They look so good! But don’t be fooled. If you get a single hypotensive reading, STOP! You have 90 seconds to figure out if it’s real, so don’t do anything else but. Check the pulse rate and character with your fingers. Do a MANUAL blood pressure check. It’s fast and accurate. If you have the slightest doubt, ASSUME IT’S REAL. Remember, your patient is bleeding to death until proven otherwise. And it’s your job to prove it. Fast!
