What systolic blood pressure range is acceptable for blood donors?

The acceptable systolic blood pressure range for blood donors typically falls between 80 and 180 mmHg. This range is established to ensure the safety and well-being of both the donor and the recipient of the donated blood. Systolic blood pressure measures the pressure in the arteries when the heart beats, and maintaining it within this range indicates that the cardiovascular system is functioning adequately.

Blood donation guidelines emphasize the importance of this range because values outside can indicate potential health risks. For example, a systolic blood pressure lower than 80 mmHg may suggest a donor is experiencing hypotension, which could lead to complications during or after donation. Conversely, readings above 180 mmHg might be indicative of hypertension, which could pose risks to the donor's health and affect the quality of the donation.

The other ranges provided do not align with the established guidelines for blood donation. High values in options may suggest that donors are not suitable for donation, while very low values could indicate an increased risk of adverse effects during the donation process. Hence, the range of 80-180 mmHg is considered the standard for a safe and effective blood donation process.
