Dyspnea Flashcards
Cardiac abnormalities that lead to an increase in pulmo venous pressure; hydrostatic pressure is increased and fluid exits capillary at faster rate
Cardiogenic pulmonary edema
Primary protein in plasma; low in currhosis and nephrotic; not enought to cause ibterstitial edema when low
Albumin
Early signs of pulmonary edemA
Exertional dyspnea
Orthopnea
Pulmonary edema dt damage of capillary lining
Noncardio PE
Characterized by inteapulmonary shunt with hypoxemia and decreased pulmo compliance
Nancardio PE
Injury Consequence of mediators that reach lung via bloodstream
Indirect
Distinguish non to cardiogenic PE
cardio: Hypoxemia- can be resolved with oxygen Pleural effusion - common Alveolar infiltrates - perihilar ( non: uniform all over) Heart - cxr enlarged
Dyspnea in the upright position and relieved in supine
What should be considered with this condition?
Platypnea
L atrial myxoma or Hepato-pulmo syndrome
Inability to speak in full sentences before stopping to get deep breath siggests?
Stimulation of the controller or impairment of the ventilatory pump with reduced vital capacity
Evidence of increased work of breathing?
Accesory muscles
Supraclavicular retractions
Tripod position
Indicative of: increased airway resistance or stiff lungs/chestwall
Pulsus paradoxus >10 mmhg suggests?
Copd or acute asthma
In supine, the abdomen has paradoxical movements such as inward motion during inspiration. This suggests?
Diaphragmatic weakness
In lung volumes? High indicates what? Low?
High- obstructive
Low- edema, fibrosis, diaphragm dysfucn, chest wall problem
Unilateral effusions indicative of?
Carcinoma or pulmo embolism
Useful in patients with intermittent sx of asthma but normal lung PE
Bronchoprovocation test
