pulmonary edema
Pulmonary edema is a condition characterized by fluid
accumulation in the lungs caused by back pressure in the
Lung veins.
Lung/pulmonary congestion , Lung water
cause
A) cardiogenic : rise of pulmonary hydrostatic
(1) LA outflow impairment ,
(2) LV systolic or diastolic dysfunction ,
(3) LV volume overload ,
(4) LV outflow obstruction
B) noncardiogenic:
pulmonary capillary permeability ↑blood pulmonary capillary pressure is normal
acute respiratory distress syndrome
pathophysiology
Cardiogenic
pulmonary edema,left ventricular dysfunction,pulmonary capillary permeability ↑
pulmonary capillary wedge pressure : PCWP
non cardiogenic acute respiratory distress syndromePCWP
non cardiogenic rare type
(1) altitude pulmonary edema
(2)neurogenic pulmonary edema
(3) Surgery
(4) toxic gases : Nitrogen dioxide, CO, Smoke
Symptoms
Extreme shortness of breath,
severe difficult breathing ,
Feeling of "air hunger" ,
Inability to lie down ,
Rales ,
Wheezing
Anxiety ,
Cough , Excessive sweating ,
Pale skin ,
Coughing up blood ,
diagnosis
1) Chest PA
2) EKG : T wave inversion, QT↑
3) Swan-Ganz catheterization
4) Plasma brain natriuretic peptide (BNP) 20pg/ml
treatment
Hospitalization ,
Oxygen is given ,
Medications FurosemideMorphine vasodilators
acute respiratory distress syndrome
Severe, acute lung injury involving diffuse alveolar damage, increased microvascular permeability and
non cardiogenic pulmonary edema acute refractoryhypoxemia
diagnosis
Acute onset
Oxygenation Pao2/Flo2<200 mmHg
Chest RadiographBilateral infiltrates seen on frontal chest radiograph
Pulmonary Artery Wedge Pressure
CAUSE
Direct Lung Injury: a) pneumonitis
b) pulmonary contusion, penetrating lung injury
c) fat emboli
d) drowning
e) inhalation injury
f) lung transplant
Indirect lung injurya) sepsis
b) severe trauma
c) drug over dose

e) transfusion of multp blood products
phase
1. Exudative (acute) phase - 0- 4 days
2. Proliferative phase - 4- 8 days
3. Fibrotic phase - >8 days
4. Recovery
pneumonia
Pneumonia is an infection of one or both lungs which is
usually caused by bacteria, viruses, or fungi.
(1)community-acquired pneumonia :
Streptococcus pneumoniae,Haemophilus influenzae,Moraxella catarrhalis,Mycoplasma pneumoniae,Chlamydia pneumoniae, Legionella pneumoniae
(2)hospital-acquired pneumonia :
Klebsiella pneumoniae,Escheichia coli,Pseudomonas aeruginosa,Staphylococcus aureus
symptoms:
fever, chills ,(cough, sputum, shortness of breath, Hemoptysis, chest
pain)
acute and purulent sputum- Bacterial pneumonia
subacute and not sputum - atypical pneumonia
hospital-acquired pneumonia
diagnosis
Laboratory
leukocytosis ,
Chest Radiographradiological infiltration: infiltration
Gram stain and microbiological culture
treatment
drugs
beta-lactam, macrolide,quinolone,tetracy-cline
lung abscess
A localized area of destruction of lung parenchyma in
which infection by pyogenic organisms results in tissue
necrosis & suppuration
Primary = abscess in previously healthy patient or in a
patient at risk for aspiration
Secondary = associated bronchogenic neoplasm or immunocompromised patient.
cause
Peptostreptococcus, F. nucleatum,P. melaninogenica,Klebsiella pneumoniae,Staphylococcus aureus,Haemophilus influenzae
diagnosis
cough,purulent sputum,hemoptysis,chest pain , increase of white blood cell count
Treatmentpostural drainage
DrugPenicillin
Surgery
tuberculosis
TB, is an infectious bacterial disease caused by Mycobacterium tuberculosis, which most commonly affects the lungs. It is transmitted from person to
person via droplets from the throat and lungs of people
with the active respiratory disease
Mycobacterium
Nontuberculous mycobacteriosis(Mycobacterium avium, Mycobacterium kansasii)
Symptoms (usually) lungs
lymph nodes ,bones, joints,
other organs fever , leukocytosis ,anemia, cough,hemoptysis ,dyspnoea
diagnosis
Chest Radiograph
primary - middle lobe , lower lobe, ipsilateral en-larged
lymph
second - both lesions( upper) , Fibrosis, calcification
tuberculosis’mass,
bronchiectasis,
airway obstruction,
pulmonary embolism,
pleural effusion,
Sputum examination
There are direct smear and culture
Direct smear examination is only positive when large numbers of bacilli begin to be excreted
A negative smear by no means excludes tuberculosis
A negative smear in the presence of extensive disease and cavitation makes the diagnosis less likely.
Particularly if the negatives are frequently repeated
Tuberculin testing
A positive tuberculin test although it is of great use in children, but it has limited diagnostic significance in older age groups
less than 5 mm (-) 5-9 mm is considered positive (+)10-19 mm is considered positive (++) more than 20 mm is considered positive (+++)
treatment
drugs isoniazid,rifampicin,ethambutol,pyrazina-mide,streptomycin
bronchiectasis
Bronchiectasis is a term that describes damage to the walls of the large airways, or bronchial tubes, of the
lung. Inflammation due to infection or other causes destroys the smooth muscles that allow the bronchial tubes to be elastic and prevents secretions that are normally made by lung tissue to be cleared
cause Infectious causes
A) Virus Infection: Adenovirus, Influenza virus
B) Bacterial infection: Staphylococcus aureus, Klebsiella,
C) Tuberculosis
decrease of the host defense mechanism
Localized impairment
Generalized impairment:(1) panhypogammaglobulinemia,(2) primary ciliary dyskinesia,(3) cystic fibrosis
other cause ammonia ,
allergic bronchopulmonary aspergillosis(ABPA)
ulcerative colitis ,
rheumatoid arthritis ,
Sjögren's syndrome,
symptoms
Continuous or recurrent cough,
purulent sputum ,
hemoptysis,
dyspnoea ,
wheezing
