---|---|---|---|---|---|
Absent breath sounds | show 🗑
|
||||
show | the tension or pressure that must be generated by a chamber of the heart in order to contract, such as that required to eject blood into the aorta
🗑
|
||||
Aldosterone | show 🗑
|
||||
show | a state of shock caused by a severe allergic reaction that lowers blood pressure and results in urticaria, breathing difficulties and possibly death. Presence of vasodilator substances in the blood.
🗑
|
||||
show | a condition in which hemoglobin concentration is below normal because of a deficiency in red blood cells, a low level of hemoglobin in cells or both; it manifests as pallor of the skin and mucous membranes, weakness, dizziness, easy fatigability, and dro
🗑
|
||||
show | mild to moderate anemia secondary to a chronic disease such as infection, inflammation, or malignancies that causes hypoferremia.
🗑
|
||||
Aneurysm | show 🗑
|
||||
show | a condition in which myocardial ischemia caused by reduced blood flow through the blood vessels of the heart cause chest pain. Ischemia - don’t have enough oxygen. Infarction - dead
🗑
|
||||
Angiotensin I | show 🗑
|
||||
Angiotensin II | show 🗑
|
||||
show | a condition in which the aortic valves do not open completely, thereby increasing afterload so that more pressure must be generated in the left ventricle to eject blood, a condition that results in ventricular hypertrophy
🗑
|
||||
Aphasia | show 🗑
|
||||
show | a condition in which the bone marrow does not product adequate amounts of new cells to replenish the blood cells lost during insults such as an autoimmune disorder or exposure to radiation or substances such as benzene or certain drugs.
🗑
|
||||
Apnea | show 🗑
|
||||
show | a condition in which the blood vessel walls, thicken, harden, lose elasticity, and typically accumulate lipids, resulting in elevated blood pressure and constriction of the coronary arteries and pain when walking caused by decreased perfusion to leg vess
🗑
|
||||
show | a chronic inflammatory respiratory disease marked by periodic attacks of wheezing, shortness of breath, a tight feeling in the chest, and a cough that produces mucus caused by an allergic reaction, certain drugs or irritants, exercise or emotional stres
🗑
|
||||
show | neuroglial cell of the CNS that branches into many processes (bbb) and functions to fill spaces between neurons and surrounding blood vessels.
🗑
|
||||
show | a breathing pattern of unpredictable irregularity. See this in severe head trauma and damage to the respiratory centers, brain abscesses, heat stroke, spinal meningitis, encephalitis.
🗑
|
||||
Atelectasis | show 🗑
|
||||
Atherosclerosis | show 🗑
|
||||
show | any of a group of congenital heart diseases involving the interartrial septum of the heart that separates the right and left atria, which results in misdirected flow of blood between the two sides of the heart. ****
🗑
|
||||
show | a condition in which a large hole is present in the center of the heart where the wall between the upper chambers joins the wall between the lower chambers, and the tricuspid and mitral valves are formed into a single layer valve that crosses the defect.
🗑
|
||||
Atrioventricular node | show 🗑
|
||||
show | see spinal cord injury --- 3 key words - noxious stimuli, severe headache, severe HTN, tanking of heart rate - roll over, check skin - ingrown toenail
🗑
|
||||
show | nerve endings located in the heart, aortic arch, and carotid sinuses that sense changes in blood pressure and volume.
🗑
|
||||
Brain stem death | show 🗑
|
||||
show | slow breathing with regular depth and rate.
🗑
|
||||
show | a condition in which the bronchi of the lungs become dilated in response to obstruction
🗑
|
||||
Bronchiolitis obliterans | show 🗑
|
||||
Bronchopulmonary dysplasia (BPD) | show 🗑
|
||||
show | bundle of specialized heart muscle cells located between the AV node and the ventricles that functions to conduct electrical impulses from the atria to the ventricles.
🗑
|
||||
Cardiac cycle | show 🗑
|
||||
Cardiogenic shock | show 🗑
|
||||
show | a condition in which the cardiac muscle of the heart wall is deteriorated by ischemic or nonischemic mechanisms.
🗑
|
||||
Cerebral death | show 🗑
|
||||
Cerebral palsy | show 🗑
|
||||
show | localized brain infarction that may result in facial, arm or leg numbness and weakness, confusion, difficulty speaking or understanding, visual disturbances, dizziness, loss of balance, difficulty walking and headache.
🗑
|
||||
Dissecting aneurysm | show 🗑
|
||||
Hypoventilation | show 🗑
