A restrictive lung disorder
Mediators for Type 1 hypersensitivity reaction
Give this one a try later!
*Histamine: contracts bronchial smooth muscles, increases vascular
permeability, and causes vasodilation
*Bioactive lipid-derived mediators (i.e. leukotrienes, PAF, prostaglandins):
released slowly, cause recruitment of other inflammatory cells (neutrophils,
eosinophils) to promote vascular permeability and edema,
bronchoconstriction or rhinitis, induces further release of histamine
Define normochromic anemia
Give this one a try later!
RBCs have normal hgb, normal color
MCHC is normal (bt 32-36%)
Types: aplastic, post-hemorrhagic, and hemolytic
Define thrombocytopenia
Give this one a try later!
, platelet count less than 150K of blood; decreased platelet production,
increased consumption, or both
Define obstructive pulmonary disease
Give this one a try later!
Airway obstruction that worsens with expiration
More force or more time is required to expire air and emptying lungs is
slowed
*infiltration of the lung by inflammatory cells with the release of numerous
cytokines that contribute to airway damage and mucus production
*decreased FEV1 (<80%)
*FEV1/FVC <70%
*FVC <80%
*TLC >120%
Define right heart failure
Give this one a try later!
Inability of the right ventricle to provide adequate blood flow into the
pulmonary circulation
*results from severe LHF
Posthemorrhagic anemia
Give this one a try later!
, Normocytic-normochromic anemia: caused by acute blood loss
# of RBCs lost is greater than # of RBCs produced
MCV and MCHC are normal, high reticulocyte count
Define peripheral artery disease
Give this one a try later!
Atherosclerotic disease of arteries that perfuses the limbs, especially the
lower extremities
Define spirometry
Give this one a try later!
Measures exhaled flow rates and volumes such as TV, VC, and FEV1
Transfusion reaction
Give this one a try later!
a serious, and potentially fatal, complication of a blood transfusion in which
a severe immune response occurs because the patient's blood and the
donated blood do not match
