How do I know if I have low blood pressure or high? |
There is a blood drive going on at my school, but I think I may have low blood pressure...and I dont really know if it would be safe for me to donate. unless you have yourself tested, or you feel very faint while standing up, for example, you won't really know if you have low blood pressure, and you definately will not know if you have high blood pressure unless you measure it...that's why they call hypertension a silent killer...because people have it and don't know it. First of all........the doctors or nurses there know the guidlines of who should and shouldn't be giving blood. They know what they are doing. Let them check your blood pressure one way or another......eventually it is your decision to donate the blood. you aren't obligated becasue they checked your b/p a lot of pharmacies have blood pressure testing devices. it's easy - you just put your arm in, it squeezes a bit, and it's done. you could also ask your school nurse or the people doing the drive if they can test you. if you're not comfortable donating, ask if you can volunteer or something else to help if you want. it's ok. The people at the drive will tell you. When you have your blood pressure taken, the nurse inflates the cuff to about 300 mm/hg. When this level is reached, she will then slowly deflate the cuff. She is looking for two number, the systolic and the diastolic. The systolic is the high number, or the number when your heart is at the peak pressure when it is pumping. Then while the cuff is still deflating, she is looking for the diastolic. This is the low number. This is the pressure that your system has at all times. A normal range is read as 120/80 Or 120 over 80. High blood pressure is considered when the low number is over 95. There is a nurse who will take your blood pressure prior to you donating blood. She will tell you if your pressure is low or high. you won't know one way or the other until you get checked over a 5-day period. Well, go visit the nurse and ask her to take your blood pressure. |
