Phlebotomy

The process of collecting blood to aid in the diagnosis of disease.

Syringe Method

A method of obtaining blood with less pressure on the vein, allowing for greater control of blood flow.

Winged Infusion Set

Used mostly for small veins, particularly in pediatrics and geriatric patients, to reduce safety risks.

Capillary Puncture

A method necessary for infants and children to collect a limited amount of blood.

Tourniquet

A device applied to the arm to slow blood flow and make veins more prominent.

Isopropyl Alcohol

The suggested antiseptic for cleansing the puncture site before blood collection.

Median Cubital

The preferred vein for venipuncture due to its size and location.

Basilic and Cephalic

Other veins that can be used for venipuncture.

Hemoconcentration

A condition caused by prolonged use of the tourniquet that can affect blood test results.

Transfer Device

A device used to transfer collected blood into tubes for testing.

Flashback

The appearance of blood in the hub of the syringe indicating entry into the vein.

Gauze Application

Used to cover the puncture site after blood collection to control bleeding.

Safety Needle

A needle designed to reduce the risk of needlestick injuries.

Order of Fill

The specified sequence in which blood collection tubes should be filled.

Coban

An elastic bandage used to secure the gauze over the puncture site.

Hematoma

A localized swelling filled with blood resulting from a ruptured blood vessel.

Blood Culture Tubes

Sterile tubes used to collect blood samples for culture testing.

Coagulation Tube

A light blue tube used for blood clotting tests.

EDTA Tube

A lavender or purple tube that contains EDTA as an anticoagulant.

Non-Additive Tube

A red tube used for serum tests with no additives.

Heparin Tube

A green tube used for tests requiring heparin as an anticoagulant.

Oxalate/Fluoride Tube

A gray tube used for glucose testing.

Pain Management in Phlebotomy

Strategies used to minimize discomfort during blood collection procedures.

Puncture Site Care

Instructions for aftercare of the puncture site to prevent bleeding and infection.

Venipuncture Angle

The recommended angle of needle insertion, typically between 15°-30°.

Needle Gauge

The size of the needle, with smaller numbers indicating larger diameters.

Flashback Confirmation

The process of checking for blood flow to confirm entry into the vein.

Patient Instructions

Guidance provided to patients regarding blood collection and aftercare.

Laid Back Position

The recommended posture for patients during venipuncture for comfort and safety.

Aseptic Technique

Clean procedures used to prevent contamination during blood collection.

Sterile Equipment

Equipment that has been sanitized to ensure safety during procedures.

Tourniquet Duration

The maximum recommended time for tourniquet application is two minutes.

Needle Cap Removal

The act of taking off the cap just before puncturing the skin.

Plunger Technique

Technique to prevent sticking of the syringe plunger when drawing blood.

Patient Allergies

Considerations to be made regarding patient allergies prior to using equipment.

Flashback in Tubes

The observation of blood entering the collection tube indicating successful venipuncture.

Pediatric Considerations

Special techniques and equipment used for drawing blood from children.

Geriatric Considerations

Adaptations made for blood collection from elderly patients with fragile veins.

Safety Needle Activation

The process of activating protective mechanisms of safety needles after use.

Calibrated Equipment

Tools and devices designed for controlled and accurate blood collection.

Delayed Blood Processing

Time-dependent procedures that affect the quality of the blood sample.

Standard Operating Procedures (SOPs)

Documented processes that outline the steps of blood draw and handling.

Patient Identification

The importance of verifying patient identity before blood collection.

Infection Control Measures

Protocols in place to prevent the spread of infections during blood draws.

Blood Collection Tubes

Specialized tubes that maintain the integrity of blood samples for testing.

Post-Venipuncture Care

Care instructions provided to the patient after the blood collection is complete.

Continuous Monitoring

The practice of observing the patient during and after the venipuncture process.

Equipment Assembly

Preparation of all necessary tools and supplies prior to starting the blood draw.
