1. PROCESSING OF BLOOD FOR TRANSFUSION

2. PROCESSING OF BLOOD FOR TRANSFUSION BLOOD COMPONENTS OR BLOOD PRODUCTS USED FOR TRANSFUSION : I.WHOLE BLOOD: WHOLE BLOOD IS COLLECTED FROM A DONOR TRANSFUSED TO THE PATIENTS BEFORE TRANSFUSION DO THE NEEDFUL TESTS TO WHOLE BLOOD AND THEN GIVEN Eg.SURGICAL PATIENT,OPEN HEART SURGERY

3. PROCESSING OF BLOOD FOR TRANSFUSION II.PACKED CELLS: FOR TREATING ANAEMIA,A DOCTOR CAN REQUEST FOR PACKED CELLS WITH ONLY THE AIM OF INCREASING THE NUMBER OF RBC BUT NOT VOLUME OF BLOOD

4. PROCESSING OF BLOOD FOR TRANSFUSION PREPARATION OF PACKED CELL: COLLECT WHOLE BLOOD IN TO A DOUBLE BLOOD BAG FROM THE DONOR WEIGH THE BLOOD BAGS PLACE THE BLOOD BAG IN THE REFRIGERATED CENTRIFUGE CENTRIFUGE & REMOVE THE BAGS CAREFULLY FROM THE CENTRIFUGE

5. PROCESSING OF BLOOD FOR TRANSFUSION PLACE THE BAG IN THE PLASMA ASPIRATION OPEN THE TRACT OF THE SECOND BAG PLASMA WILL FLOW INTO THE SECOND BAG ALLOW THE REJEVINATING FLUID TO PRESENT IN THE FIRST BAG III.PLASMA PLASMA IS USUALLY TRANSFUSED TO DEHYDRATED PATIENTS BEFORE TRANSFUSION CHECK FOR THE NATURE OF PLASMA

6. PROCESSING OF BLOOD FOR TRANSFUSION IV. FFP (FRESH FROZEN PLASMA) FRESHLY ASPIRATED PLASMA IS FROZEN AT -20°c to 30°c TO FORM CERTAIN PRODUCT IN A FROZEN CONDITION IT IS CALLED FFP CAN PROVIDE FACTOR DEFICIENCY LIKE ANTIHAEMOPHILIC FACTOR (VIII)

7. PROCESSING OF BLOOD FOR TRANSFUSION V.CRYPPRECIPITATION THE FRESH PLATELET POOR PLASMA IS FROZEN AT -30°C INSIDE THE FRIDGE THAWES AT 1 TO 5°C WHICH FORMS CRYOPRECIPITATION PRODUCT ON TOP OF PLASMA AT THE STATE OF THAWING,CRYOPREPICIPITATE CAN BE SEPARATED FROM A SINGLE UNIT OR DIFFERENT UNIT IT CAN PROVIDE FACTOR VIII,II,XIII CP IS GIVEN IN THESE FACTORS DEFICIENCY

8. PROCESSING OF BLOOD FOR TRANSFUSION VI.PLATELETS PLATELETS SHOULD BE ALWAYS PLACED IN THE AGITATOR IT SHOULD BE USED WITHIN 72 HOURS AFTER THE SEPARATION PROVIDES PLATELETS IN CONDITION LIKE LEUKAEMIA,BLEEDING,DENGUE FEVER,etc SHOULD BE SEPARATED BY PLASMA APHERESIS PLATELETS PREPARED FROM MORE THAN ONE DONOR IS CALLED PLATELET POOLED CONDITION

10. PROCESSING OF BLOOD FOR TRANSFUSION APHERESIS: PROCEDURE DONE BY A SPECIAL APPARATUS WHERE PLATELETS AND WBC ARE SEPARATED AND OTHER RBC SENT BACK TO THE DONOR PLASMA FRACTIONS ALBUMIN,FIBRINOGEN SEPARATED BY ALCOHOL FRACTIONATION FROM FRESH PLASMA FACTOR VIII IS SEPARATED BY CRYOPRECIPITATION

11. PROCESSING OF BLOOD FOR TRANSFUSION PLASMA APHERESIS: CAN BE COLLECTED AND CELLS ARE PRESENT TO THE DONOR PLASMA COLLECTED IN CPD AND ACD DONE AS A TREATMENT IN GULLIAN BARRY SYNDROME DONE 4 TO 6 TIMES FOR THIS PATIENT
