Curiosities, Top Statistics, Facts, and Interesting Information
- Each year, approximately 5.6 million blood transfusions are performed in the United States.
- Phlebotomy, the practice of drawing blood, has been around for thousands of years.
- The most common reasons for drawing blood are to diagnose medical conditions and to monitor the effects of treatments.
- The average adult has about 1.2 to 1.5 gallons of blood in their body.
- It’s important to drink plenty of water before having blood drawn to make it easier to find a vein.
Step 1: Prepare for the Procedure
Before you begin, you’ll need to gather the necessary supplies. You’ll need:
- Gloves
- Alcohol swabs
- A tourniquet
- A needle and syringe or a butterfly needle and tubing
- A sterile gauze pad
- A biohazard sharps container
Once you have your supplies, wash your hands thoroughly and put on gloves to protect yourself and the patient from infection.
Step 2: Locate a Vein
Next, you’ll need to find a vein to draw blood from. The best veins to use are those that are visible and easy to access, such as those in the crook of the arm. Use a tourniquet to make the vein more visible and easier to access.
Step 3: Clean the Area
Once you’ve located a vein, use an alcohol swab to clean the area around the vein. This helps prevent infection.
Step 4: Insert the Needle
When you’re ready to insert the needle, hold it at a 15 to 30-degree angle to the skin and insert it into the vein. Once you see blood in the syringe or tubing, you can begin to draw blood.
Step 5: Remove the Needle and Apply Pressure
When you’ve collected enough blood, remove the needle and apply pressure to the area with a sterile gauze pad. This helps prevent bleeding and bruising.
Step 6: Dispose of Supplies
Finally, be sure to dispose of your supplies in a biohazard sharps container to prevent injury or infection to others who may come into contact with them.
