Dyspnea- MedGen UID:
- 3938
- •Concept ID:
- C0013404
- •
- Sign or Symptom
Difficult or labored breathing. Dyspnea is a subjective feeling only the patient can rate, e.g., on a Borg scale.
Respiratory insufficiency- MedGen UID:
- 11197
- •Concept ID:
- C0035229
- •
- Pathologic Function
Impairment of gas exchange within the lungs secondary to a disease process, neoplasm, or trauma, possibly resulting in hypoxia, hypercarbia, or both, but not requiring intubation or mechanical ventilation. Patients are normally managed with pharmaceutical therapy, supplemental oxygen, or both.
Exertional dyspnea- MedGen UID:
- 68549
- •Concept ID:
- C0231807
- •
- Sign or Symptom
Perceived difficulty to breathe that occurs with exercise or exertion and improves with rest.
Pulmonary alveolar proteinosis- MedGen UID:
- 1763046
- •Concept ID:
- C5400698
- •
- Finding
Accumulation of amorphous PAS-positive material in the space betweem alveolar macrophages, sometimes as condensed form (oval bodies) are typically found in alveolar proteinosis.
Ground-glass opacification- MedGen UID:
- 1779663
- •Concept ID:
- C5539411
- •
- Finding
On chest radiographs, ground-glass opacity appears as an area of hazy increased lung opacity, usually extensive, within which margins of pulmonary vessels may be indistinct. On CT scans, it appears as hazy increased opacity of lung, with preservation of bronchial and vascular margins. It is caused by partial filling of airspaces, interstitial thickening (due to fluid, cells, and/or fibrosis), partial collapse of alveoli, increased capillary blood volume, or a combination of these, the common factor being the partial displacement of air. Ground-glass opacity is less opaque than consolidation, in which bronchovascular margins are obscured.
Interlobular septal thickening- MedGen UID:
- 1779791
- •Concept ID:
- C5539418
- •
- Finding
Presence of thickening of the interlobular septa of the lungs as seen on a CT scan.
- Abnormality of the respiratory system
