High Yield Handout Dyspnea Flashcards
ATS definition of dyspnea
subjective experience of breathing discomfort that consists of quantitatively distinct sensations that vary in intensity.
Dyspnea is
a self reported symptom
Tachypnea is
a sign that is characterized by accessory uscle use and intercostal retractions due to the increased work of breathing
85% of SoB is caused by
cardiac and pulmonary
COPD
strongly associated with smoking, occupational lung disease, or medication.
Progressive symptoms over a long period of time leading to the feeling that one is unable to take a breath
stable angina
typically described as heavy, squeezing, pressure, tightness or choking but rarely as pain
angina equivalents include dyspnea, nausea, and fatigue
typically relieved with rest in 1-5 minutes
compare side to side in lung exam in a what pattern?
ladder
when listening to the lungs patient should breathe
with mouth open
common findings with COPD
barrel chest
limited rib motion
percussion yielding generalized hyperresonance
decreased breath sounds
rib motion is what for pulmonary complaints
a ‘special test’
1st step of dyspnea diagnostics
walking oximetry
peak flow assessment
2nd step of dyspnea diagnostics ‘phase 1’
chest x-ray
spirometry
EKG
CBC/BMP
3rd step of dyspnea diagnostics ‘phase 2’
Chest CT
Lung volumes/DLCO/tests
Echocardiogram
Cardiac stress Test
4th step of dyspnea diagnostic ‘phase 3’
consider cardiopulmonary exercise testing (and referral)
COPD diagnostic requirement
FEV/eFEV <70%
Typical X-ray findings of COPD
flattening of the diaphragm
increased AP diameter
sympathetic to heart
T1-6
