The American Red Cross has declared an emergency blood shortage, with national inventory dropping over 25% since July 1 due to extreme heat and summer travel, which caused the cancellation of more than 100 blood drives. The organization reports a shortfall of over 17,000 blood donations, particularly affecting type O blood, which is critical for emergency medical situations. Hospitals are currently receiving blood products faster than they are being donated, leading to reduced distributions of this vital blood type, which is essential for accident and trauma victims. The Red Cross urges all blood types to donate now to help replenish supplies before patient care is impacted. To encourage donations, those who give blood, platelets, or plasma through August 31 will receive a $20 Amazon gift card. Donors can schedule appointments via the Red Cross Blood Donor App or by visiting their website.
