Study Notes

Blood Donation and Transfusion Considerations

Blood from patients or donors with certain medical conditions may be unsuitable for transfusion.
Individuals may be disqualified from donating blood for various underlying health issues.
Clinicians should consider the risks of transfusion-transmissible infections when selecting blood products for patients.

Platelet Donation Guidelines

A minimum of 4 weeks is required between platelet donations.
Plateletpheresis reduces the donor’s platelet count by 30% to 60%.
If a platelet count is assessed post-collection, it should reflect this decrease.

Deferral Periods

Donors with a history of brucellosis are deferred for 2 years following their last febrile episode.

True/False Statements on Blood Donation

A donor with a history of hepatitis C is permanently deferred from donating blood.
When oxygen demand exceeds 50% of the available content, compensatory mechanisms fail and transfusion becomes necessary.

Transfusion Therapy Uses

Transfusion therapy is primarily utilized to address two medical conditions, which are unspecified in the provided text but typically include anemia and significant blood loss.
