Modern Day Phlebotomy Techniques
Venipuncture and Capillary Puncture
Centralized Phlebotomy
blood collection services are typically performed in a central location, such as a hospital laboratory or a dedicated phlebotomy center.
Patients visit this central location specifically for blood collection, regardless of where they receive their medical care.
Decentralized
involves blood collection services being performed in various locations, such as outpatient clinics, medical offices, or even patients' homes.
blood collection may be integrated into routine medical visits or performed by mobile phlebotomy teams dispatched to different locations.
Hybrid
A blend of centralized and decentralized phlebotomy
Typically sends laboratory-based phlebotomists to the nursing units during the early morning collections and then keeps a limited number of phlebotomists available the rest of the day to help patient care technicians with difficult collections.
Mostly done in the hospitals today.
Professional Traits of Phlebotomist
Dependable, Cooperative, Committed
Compassionate, Courteous, Respectful
Honesty, Integrity, Competence
Organized, Responsible, Flexible
Clothing and lab coats must be clean and unwrinkled.
Clothing worn under the laboratory coat should be conservative and meet institutional requirements.
Shoes must be clean, polished, closedtoed, and skid-proof.
Perfume and cologne are usually not recommended or must be kept to a minimum.
Hair, including facial hair must be clean, neat, and trimmed.
Personal hygiene is extremely important because of close patient contact;
Anatomical
responsible for the analysis of surgical specimens, frozen sections,biopsies, cytological specimens, and autopsies.
Clinical
responsible for the analysis of blood, bone marrow, microbiology samples, urine, and other body fluids
Cytology
Process and examine tissue and body fluids for the presence of abnormal cells, such as cancer cells. Papanicolau smear is one of the most common tests
Histology
process and stain tissues obtained from biopsies, surgery, autopsies, and frozen sections. Pathologist then examines the tissue.
Cytogenetics
the section in which chromosome studies are performed to detect genetic disorders.
Right atrioventricular valve (tricuspid valve)
Location - Between the right atrium and right ventricle
Function - Closes when the right ventricle contracts and prevents blood from flowing back into the right atrium
Left AV valve (bicuspid or mitral valve)
Location - Between the left atrium and left ventricle
Function - Closes when the left ventricle contracts and prevents blood from flowing back into the left atrium
Right semilunar valve (pulmonary or pulmonic valve)
Location At the entrance to the pulmonary artery
Function - Closes when the right ventricle relaxes and prevents blood from flowing back into the right ventricle
Left semilunar valve (aortic valve)
Location - At the entrance to the aorta
Function - Closes when the left ventricle relaxes and prevents blood from flowing back into the left ventricle
Pericardium– sac enclosing the heart
Epicardium– outermost layer of the heart wall
Myocardium– muscle of the heart itself
Endocardium– lines the inner chambers of the heart
Angina pectoris – aka ischemic heart disease; chest pain caused by inadequate blood flow to the myocardium from the coronary arteries
Bacterial endocarditis – infection of the lining of the heart
Congestive heart failure – impaired circulation due to inadequate pumping of a diseased heart resulting in edema in the lungs or other tissues
Myocardial infarction – heart attack or death of heart muscle due to obstruction of a coronary artery
SystemicCirculation
Transports oxygenated blood and nutrients from the leftventricle of the heart to the body cells and then returning to the rightatrium of the heart with blood carrying carbon dioxide and other waste products of metabolism from the cells.
Pulmonary Circulation
Transports deoxygenated blood from the right ventricle of the heart to the lungs to remove carbon dioxide and pick up oxygen
After gas exchange, blood is carried back to left atrium of the heart
Tunicaadventitia (outer connective tissue)
Tunicamedia (middle, muscle and elastic fiber)
Tunicaintima (inner, endothelial cell)
Lumen – space inside the blood vessel through which the blood flows
Valves – found in veins; these are thin membranous leaflets that prevent the backflow of blood
Aneurysm – localized dilation or bulging in the wall of a blood vessel (artery)
