A massive transfusion protocol is used when significant blood loss is present such as in major trauma, when more than ten units of blood are needed. Packed red blood cells, fresh frozen plasma, and platelets are generally administered. [131] Typical ratios of fresh frozen plasma, platelets and packed red blood cells are between 1:1:1 and 1:1:2 ...
The blood volume is 70 ml/kg body weight in adult males, 65 ml/kg in adult females and 70-75 ml/kg in children (1 year old and over). [5] [6] Total Blood Volume has been measured manually by the use of carbon monoxide (CO) as a tracer for more than 100 years and was first proposed by French scientists Grehant and Quinquaud in 1882.
Hemoglobin has an oxygen binding capacity between 1.36 and 1.40 ml O 2 per gram hemoglobin, [23] which increases the total blood oxygen capacity seventyfold, [24] compared to if oxygen solely were carried by its solubility of 0.03 ml O 2 per liter blood per mm Hg partial pressure of oxygen (about 100 mm Hg in arteries). [24]
For example, a girl seriously injured in a motorcycle crash needed to be given 24 units of blood to stabilize her. Without caring donors, she would have died. Nationally, there are about 120 ...
Nine blood drives are scheduled for the remainder of March. The Red Cross says all blood types are needed, especially type O. Donors needed to help keep blood supply growing as seasons change
The cerebral blood volume value of gray matter is about 3.5 +/- 0.4 ml/100g, and the white matter is about 1.7 +/- 0.4 ml/100g. The gray matter is nearly twice that of white matter. [3] In both white and gray matter, cerebral blood volume decreases by about 0.50% per year with increasing age. [4]
To give blood donors must weigh over 48 kg (106 lb; 7 st 8 lb). For donors who are female, aged under 20 years old, weigh under 60 kg (132 lb; 9 st 6 lb) and are under 168 cm (5 ft 6 in) height, the blood service will need to confirm their estimated blood volume is over 3500 ml. [2] HIV
