PULMO Flashcards
The most common infectious cause of acute exacerbation of bronchitis
Respiratory viruses
Respiratory viruses such as influenza A and B, parainfluenza, respiratory syncytial virus, and coronavirus have all been attributed to acute bronchitis.
Chronic Bronchitis
Productive cough for 3 months each year for 2 consecutive years, often with dyspnea and partially reversible airway obstruction.
Acute exacerbation of Chronic Bronchitis
Change in the characteristic of a productive cough that has lasted for more than 3 months for 2 consecutive years
Hallmarks of upper respiratory cough syndrome previously termed “postnasal drip.”
Rhinorrhea and repetitive throat clearing
Fever is common in patients with ________________ and is less common with ________________
Fever is common in patients with viral respiratory illnesses and is less common with pertussis infection
Acute Bronchitis
cough of at least 5 days duration and can persist up to 20 days
risk factor for penicillin resistance
Immunosuppression from alcoholism or
cancer
Poor prognostic factors in Elderly
fever greater than 38.3◦C
leucopenia
immunosuppression
gram-negative or staphylococcal infection
cardiac disease
bilateral infiltrates
Chronic alcoholism
S. aureus
S. pneumoniae
Klebsiella pneumoniae
Pseudomonas aeruginosa
distinguishing a chronic obstructive pul- monary disease (COPD) exacerbation from congestive heart failure (CHF)
B-type natriuretic peptide level
ACUTE COUGH
<3 weeks
Associated with self-limited URTI or bronchial infection
URTI: rhinitis, sinusitis, pertussis
LRTI: bronchitis, pneumonia
Allergic reaction
Asthma
Environmental irritants
Transient airway hyperresponsiveness
Foreign body
Hallmark of acute bronchitis
PRODUCTIVE COUGH
SUBACUTE COUGH
3-8 weeks
postviral airway inflammation with bronchial hyperresponsiveness
mucus hypersecretion
upper airway cough syn- drome (postnasal discharge),
asthma
Most likely cause of subacute cough
Postinfectious cough
CHRONIC COUGH
> 8 weeks
MCC of Chronic cough
(1) smoking, often with chronic bronchitis; (
2) upper airway cough syndrome (formerly postnasal discharge);
(3) asthma;
(4) gastroesophageal reflux; and
(5) angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker therapy
Feeling of difficult, labored, or uncomfortable breathing “Shortness of breath,” “breathlessness,” or “not getting enough air”
Dyspnea
Rapid breathing
Tachypnea
Dyspnea in the recumbent position
Orthopnea
Orthopnea that awakens the patient from sleep
Paroxysmal nocturnal dyspnea
Dyspnea associated with lying on one side (lateral decubitus position) but not the other side
Patient lies on the side of the more affected lung where gravity increases blood flow to the worse lung and reduces it to the better lung
Trepopnea
Dyspnea in the upright position
Results from:
Loss of abdominal wall muscular tone
Right-to-left intracardiac shunting (patent foramen ovale)
Platypnea
