Blood donor Screening Flashcards
What are the order of Blood Donation?
- Blood donor selection
- Blood collection
- Unit processing and component processing
- Compatibility testing/Pre-transfusion testing
- Blood transfusion
- **Transfusion reactions
What are the components included in Donor screening?
- medical history,
- physical examination,
- serological testing
Why is proper Donor selection important?
Keywords: Safe transfusion
Why is Medical History important in blood donation?
- to make sure the donor is well fit for donation, and
- to make
sure the blood is safe and - beneficial to the recipient of the blood
Give the 6 components for Physical examination:
- Weight
- Temperature
- Pulse
- Blood pressure
- Hemoglobin
- Hematocrit
Give the normal values for an Ideal donor based on these criterion:
- Weight
- Temperature
- Pulse
- Blood pressure
- Hemoglobin
- Hematocrit
- 110 lbs / 50kg (Standard)
- <37.5°C (99.5°F)
- 50—100bpm
Systolic: 90—160 mmHg (should not >180 mmHg)
Diastolic: 60—100 mmHg (should not >100 mmHg)
> 12.5 g/dL (125 g/L)
Autologous: >11 g/dL
> 38%
Autologous: >33%
What is the required ideal age of a blood donor?
Ages: 18-65 years old
Can a blood donor be the recipient?
Yes, especially in cases of surgery the patient may donate blood prior to a major surgery and is deemed as AUTOLOGOUS
How does a 17 years old able to donate blood?
With parent’s consent
How does a donor above 65 years old able to donate?
With physician’s consent
____________ donors should be informed of the procedure for
donating blood and its potential risks
Consent to donate
What should you do if the donor is weighing less than the requirement weight?
Perform volume adjustments.
decrease the blood to collect and AC in the primary bag
< 110 lbs/50 kg
Give the three equations for volume adjustments:
Maximum blood to donate:
Donor weight/Ideal weight (110lbs/50kg) x 450 mL
Volume of AC needed:
Maximum blood to donate/100 x 14
Volume of AC to be removed from the primary bag:
63 - (Volume of AC required)
Standard volume for anticoagulant
63 mL AC
TRUE or FALSE: A blood bag unit is an open system
FALSE; the Blood bag unit is a closed system to avoid contamination. Accessing the inner portion requires the use of needles, and upon removal of AC this is now considered and open system
