Anatomy and Physiology of the Circulatory System

The circulatory system is the body’s transportation network, delivering oxygen and nutrients to cells and removing waste products. It’s a complex system made up of the heart, blood vessels, and blood. Understanding the structure and function of each component is crucial for phlebotomists, as it helps you understand the process of blood collection and its potential implications.

The Heart

The heart is a muscular organ located in the chest, slightly to the left of the center. It’s responsible for pumping blood throughout the body. The heart has four chambers: two upper chambers called atria and two lower chambers called ventricles.

• The right atrium receives deoxygenated blood from the body.
• The right ventricle pumps this deoxygenated blood to the lungs.
• The left atrium receives oxygenated blood from the lungs.
• The left ventricle pumps oxygenated blood to the rest of the body.

The heart’s rhythmic contractions, called heartbeats, are controlled by electrical impulses generated by specialized cells within the heart itself.

Blood Vessels

Blood vessels are the network of tubes that carry blood throughout the body. There are three main types of blood vessels:

• Arteries: These vessels carry oxygenated blood away from the heart. They have thick, elastic walls to withstand the high pressure of blood pumped from the heart. Arteries branch into smaller vessels called arterioles.
• Veins: These vessels carry deoxygenated blood back to the heart. They have thinner walls than arteries and contain valves to prevent backflow of blood. Veins branch into smaller vessels called venules.
• Capillaries: These are the smallest blood vessels, connecting arteries and veins. They are thin-walled, allowing for the exchange of gases, nutrients, and waste products between blood and the surrounding tissues.

Blood Components

Blood is a vital fluid that carries oxygen, nutrients, and hormones throughout the body, and removes waste products. It’s composed of plasma and various blood cells:

• Plasma: The liquid portion of blood, containing water, proteins, electrolytes, and other substances.
• Red blood cells (RBCs): These cells contain hemoglobin, a protein that binds to oxygen and carries it to the body’s tissues. They are responsible for the red color of blood.
• White blood cells (WBCs): These cells are part of the immune system, fighting infections and diseases. They are larger than RBCs and have a nucleus.
• Platelets: These are cell fragments involved in blood clotting. They stick to damaged blood vessels, forming a plug to stop bleeding.

Blood Circulation

The process of blood circulation involves the continuous flow of blood throughout the body.

The heart pumps blood through arteries to the body’s tissues. Oxygen and nutrients are exchanged in capillaries, and waste products are collected. Deoxygenated blood then flows back to the heart through veins, completing the cycle.

Equipment and Supplies

Phlebotomy involves the use of specialized equipment and supplies to ensure safe and accurate blood collection. Understanding the purpose and proper handling of these tools is essential for any phlebotomist.

Blood Collection Tubes

Blood collection tubes are the primary containers for collecting and storing blood samples. They come in various colors, each representing a different additive that helps preserve the blood for specific tests.

• Red-top tubes:Contain no additives and are used for serum testing, such as blood chemistry and serology. They allow the blood to clot naturally before the serum is separated.
• Lavender-top tubes:Contain EDTA (ethylenediaminetetraacetic acid), an anticoagulant that prevents blood clotting. These tubes are used for hematology testing, such as complete blood count (CBC).
• Light blue-top tubes:Contain sodium citrate, another anticoagulant that prevents blood clotting. These tubes are used for coagulation testing, such as prothrombin time (PT) and partial thromboplastin time (PTT).
• Green-top tubes:Contain heparin, an anticoagulant that prevents blood clotting. These tubes are used for chemistry testing, such as electrolytes and blood gases.
• Gray-top tubes:Contain sodium fluoride and potassium oxalate, which act as an anticoagulant and a glucose preservative, respectively. These tubes are used for glucose testing.

Needles

Needles are essential for drawing blood. They come in various sizes and gauges, depending on the type of blood collection and the patient’s vein size.

• Gauge:The gauge of a needle refers to its diameter. A smaller gauge number indicates a larger diameter needle, while a larger gauge number indicates a smaller diameter needle. For example, a 21-gauge needle is larger than a 23-gauge needle.

• Length:The length of a needle also varies depending on the patient’s vein depth and the type of blood collection. A shorter needle is typically used for superficial veins, while a longer needle is used for deeper veins.

Syringes

Syringes are used to draw blood from a vein. They come in various sizes, depending on the volume of blood needed for the test.

• Safety syringes:These syringes have a built-in safety mechanism that retracts the needle after use, reducing the risk of needlestick injuries.
• Disposable syringes:These syringes are used only once and then discarded. This helps to prevent the spread of infection.

Tourniquets

Tourniquets are used to constrict blood flow in a vein, making it easier to locate and draw blood. They are typically made of latex or fabric and are applied to the upper arm, just above the elbow.

• Proper application:The tourniquet should be applied snugly but not too tightly, as this can restrict blood flow and cause discomfort to the patient.
• Time limit:The tourniquet should not be left in place for more than one minute, as this can cause tissue damage.

Alcohol Swabs

Alcohol swabs are used to disinfect the skin before drawing blood. They are typically made of gauze or cotton and are soaked in isopropyl alcohol.

• Proper technique:The alcohol swab should be used in a circular motion, starting from the center of the puncture site and moving outwards. The area should be allowed to air dry completely before the needle is inserted.
• Alternatives:For patients with sensitive skin or allergies to alcohol, alternative disinfectants such as povidone-iodine swabs can be used.

Bandages

Bandages are used to cover the puncture site after blood has been drawn. They help to stop bleeding and prevent infection.

• Types of bandages:Bandages come in various sizes and materials, including adhesive bandages, gauze pads, and pressure dressings.
• Proper application:The bandage should be applied securely but not too tightly, as this can restrict blood flow.

Advanced phlebotomy techniques, such as arterial puncture and central line access, require specialized knowledge and skills. These procedures are typically performed by experienced phlebotomists or other healthcare professionals, and they involve a higher level of risk than standard venipuncture. This section will provide a comprehensive guide to these techniques, including anatomy, procedure, complications, and clinical applications.

Arterial Puncture

Arterial puncture is a procedure used to obtain arterial blood samples for various diagnostic tests, such as blood gas analysis, arterial blood pressure monitoring, and arterial blood cultures. Arterial blood differs from venous blood in its oxygen content, which is higher in arterial blood.

• The radial artery is located on the thumb side of the wrist, just below the base of the thumb. It is relatively superficial and easy to palpate. The brachial artery is located in the upper arm, just inside the elbow.

  It is larger than the radial artery and has a stronger pulse. The femoral artery is located in the groin, just below the inguinal ligament. It is the largest artery in the lower extremities and has a deep, strong pulse.

• Patient preparation for an arterial puncture involves positioning the patient comfortably, typically with the arm extended and supported. The puncture site should be cleaned with an antiseptic solution, and the patient should be informed of the procedure and potential risks.

• The puncture technique involves selecting a suitable needle, typically a 22-gauge or 23-gauge needle. The needle should be inserted at a 45-degree angle into the artery, with the bevel facing upwards. Pressure should be applied to the artery both proximal and distal to the puncture site to prevent bleeding.

• Post-procedure care involves applying pressure to the puncture site for several minutes to ensure hemostasis. The puncture site should be monitored for bleeding or hematoma formation. The patient should be instructed to avoid strenuous activity and to report any unusual symptoms to their healthcare provider.

• Potential complications associated with arterial puncture include hematoma, arterial spasm, and nerve damage. Hematoma can occur if the needle punctures a vein or if pressure is not applied adequately. Arterial spasm can occur if the artery is irritated by the needle or if the patient is anxious.

  Nerve damage can occur if the needle punctures a nerve or if the nerve is compressed during the procedure.

Central Line Access

Central venous catheters are long, thin tubes inserted into a large vein, typically in the neck, chest, or groin. They provide access to the central venous system, which allows for the administration of medications, fluids, and blood products.

• Peripherally inserted central catheters (PICCs) are inserted into a vein in the arm and threaded into a large vein in the chest. PICCs are typically used for long-term medication administration and are less invasive than other types of central venous catheters.

• Tunneled central venous catheters are inserted into a vein in the chest or neck and tunneled under the skin to a subcutaneous pocket. Tunneled catheters are typically used for long-term medication administration and are less prone to infection than PICCs.

• Implanted ports are small, flat devices that are surgically implanted under the skin. A port is connected to a central venous catheter that is inserted into a large vein in the chest. Implanted ports are typically used for long-term medication administration and are very discreet.

• Flushing a central venous catheter involves injecting a small amount of saline solution or heparin solution into the catheter to prevent occlusion.

• Dressing changes for central venous catheters involve removing the old dressing, cleaning the insertion site, and applying a new dressing.

• Troubleshooting common problems associated with central venous catheters involves identifying the cause of the problem and taking appropriate steps to resolve it. For example, if a central venous catheter is occluded, it may need to be flushed or replaced.

  If a central venous catheter is infected, it may need to be removed and replaced.
