Flashcards in Respiratory Diseases Deck (28):
1

volume of blood contained in the lungs after a maximal inspiration

Total Lung Capacity

2

volume of gas remaining in the lungs at the end of a maximal expiration

Residual volume

3

volume of gas that is exhaled in the Iungs at the end OF a maximal expiration

vital capacity

4

major risk Factor for Asthma

Atopy

5

Atopic Diseases common in Asthma

Allergic rhinitis ( > 80% of patients)
Atopic dermatitis( eczema)

6

most common causes of Viral U RTI triggering Asthma

RSV
Rhinovirus
Corona virus

7

Can worsen asthm due to increased Cholinergic bronchospasm

Beta blocker

8

Asthma trigger that induces an increase in the airway Osmolality leading to activation or mast ells to release in flammatory mediators

Exercise

9

most common trigger of Asthma

viral infection

10

Physiologic Abnormality of Asthma

AHR

11

Asthma phenotype which often commences in childhood and i associated with a past and/ or Family history of Allergy disease such as eczema, allergic rhinitis, or Food or drug allergy
Eosinophilic airway inflammation
Responds well to ICS treatment

Allergic Asthma

12

Asthma phenotype that often responds less to ICS
sputum of these patients may be neutrophilic, eosinophilic or panci granulocytic

Non - Allergic Asthma

13

some adults particularly women present with asthma for the first time during adult life
now allergic, often requiring high doses of ICS or are relatively refractory to corticosteroid treatment

Late Onset Asthma

14

Improves diagnostic accuracy and may eliminate the need for biopsy especially in IPF

HRCT

15

most common clinical presentation in bronchiectasis

persistent productive cough Production of thick tenacious sputum

16

Tram tracks On Chest CT

Bronchiectasis

17

Light's criteria

PF/ S. protein >o.5
PF/ S. LDH>0.6
PF LDH> 2/3 upper normal limit
any one of the criteria

18

most common cause of pleural effusion

LV Failure

19

mechanism of pleural Effusion

increase Fluid in the lung interstitial spaces exiting in part across the visceral pleura

20

Sputum collected is from the lower respiratory tract

Alveolar macrophages and other inflammatory cells

21

Diagnostic procedure that allows recovery Of organisms such as p. jiroveci

BAL

22

Airway edema + acute inflammatory response with increase in eOsinophil and neutrophils that is not very reversible with bronchodilators

Late phase allergic reaction

23

WOrsens asthmq due to increased cholinergic bronchospasm

Beta blocker

24

Triggers asthma with increased airway inflammation with increased numbers of eosinophils and neutrophils

viral Infection

25

mechanism Of triggering asthma in exercise

Hyperventilation causes increase Osmolality of airway fluids leading to mast cell mediator release and bronchospasm

26

premenstrual worsening of Asthma

Due to fall in progesterone

27

Two types of Asthma

1 Allergic asthma
2 Idiosyncratic/ Intrinsic Asthma

28

Type of Asthma with Normal IGE levels in the blood

Idiosyncratic/ Intrinsic Asthma
