Blood Bus Drives To La Mariposa


Statistics show that 25 percent or more of us will require blood at least once in our lifetime.  Whole blood donation can help as many as three people per year.–

Last Tuesday, United Blood Services held its first blood drive at La Mariposa.  Twenty-five people donated blood, three donated double red cells.  When you do the math, that’s 75 people in Ventura County that will be helped through trauma and lifesaving procedures.  Way to make a difference La Mariposa!

Over the course of the day a few questions arose–we thought we’d answer them here:

Does blood expire?

Blood is good for 42 days.  UBS provides blood in ventura county (including Pleasant Valley Hospital). All of the donated blood is typically used in the county, but on the rare occasion that it is close to expiring, they make sure to get it to a facility that can use it.

How much blood do you take?

The amount we collect is based on your blood volume and we use your height and weight to calculate that.  Most people donate somewhere between .5-1 pint of blood.

What is double red blood cell donation?

During a Double Red Cell pheresis donation, whole blood is collected from one arm and goes into a machine called a “cell separator.” The machine separates the components and collects a measured amount of red blood cells into a special bag. Then the other components are mixed with a saline solution and returned to the donor.

Oxygen-rich red blood cells are most often used for surgery or trauma patients. Donors who donate just their red blood cells through pheresis can double the amount of red blood cells donated at one time.  Learn more…

The La Mariposa Blood Drive was one of only two in Camarillo.  Special thanks to PTA leader, Natalie Swarts for coordinating our first of hopefully many successful blood drives.
