SARASOTA - "We feel helpless when something happens, and we want to do something," says Suncoast Blood Bank community development director Jayne Giroux.

The aftermath of mass shootings commonly leads to questions and larger scale crisis, such as blood shortages.

Blood banks nationwide are called upon immediately to help. Suncoast Blood Bank community development director Jayne Giroux says staying ahead of emergencies is key.

“And quite frankly these things are happening so often we feel the need to be over prepared with our inventory every day because we don’t know when it’s going to happen," says Giroux.

She says becoming a regular donor is small way to make a difference adding blood banks desperately need O negative blood.

“When seconds matter, when you’re taken into a trauma room you’re going to start receiving O negative blood until they can type your own blood," says Giroux.

It is possible to be prepared and take a proactive approach in the face of an emergency. Sarasota Memorial Hospital offers several life-saving classes, such as “Stop the Bleed,” taught by certified Healthcare Emergency Professional Sean Alley.

“Bleeding is the number one cause of death in an incident like that," says Alley. He says teaching you basic life-saving skills to apply before first responders arrive on scene can be the difference between life and death.

“The more that people learn these skills, hopefully the less we’ll need them. We hope to alleviate in these unfortunates situations," says Alley.

Free classes will be held 2-3 p.m. the second Tuesday of each month. Visit 'Stop The Bleed' for more information on how to sign up.
