The answer to this is that the person who is donating the blood may faint or collapse due to weakness.And they also require 12 percent hepataglobin.
16 and weigh over 110 pounds.
Current FDA guidelines require volunteer blood donors weigh a minimum of 110 lbs (50 Kg). However, many blood collection centers use Body Mass Index to determine donor eligibility. This is in response to studies showing an increase in post-donation reactions in smaller weight donors. Contact your local blood collection facility and ask about the specific donor criteria used at their center.
u should eat less fatty foods ur in risk of high blood pressure
Usually 120 over 80 but some consider 110 over 70 as the normal blood pressure.
FDA guidelines allow a maximum of 10.5 ml/kg body weight to be collected at each whole blood collection, including samples for mandated screening tests. The majority of blood centers use 500 ml collection bags (+ up to 50 ml for testing). The is approximately 12% circulating blood volume in a 50 kg (110 lb) donor, representing the lowest weight a blood donor may be. This volume was selected because studies have indicated a loss of 15% or more of circulating blood volume is associated with an increase in donor reactions, such as syncope, nausea and seizure activity.
1/-110 (1 over -110) or -0.00909090909
divide both by 5 35/5 = 7 110/5 = 22 35/110 = 7/22
168/110 is the normal blood pressure for a 12 year old female if you weigh over 200 pounds. Hope It Helps!
A desirable target would be 130 over 75.
108 over 110 in simplest form = 54/55
110/80 mm/Hg
99/110 + 100/110 = 199/110 = 1 and 89/110
