Symptoms such as lightheadedness and fainting may be brought on by a rapid decrease in heart rate and blood pressure, which is known as VVR. Donors of blood can experience these symptoms either before or after the donation procedure. In 2020, 120 blood donations were part of a cross-sectional research. The blood bank database was queried for each donation in order to get the donor's demographic information as well as details pertaining to the donation itself. A t-test was used to examine blood pressure data, while a Chi-square test was used to assess qualitative data such as age group, sex, donation frequency, and location. The results of our research confirm that donating blood is a safe operation, and that stringent screening procedures prior to blood donation may further decrease the occurrence of VVR.
