Faisal with fever and respiratory distress
- presented with
- Cough
- definition
- A reflex explosive
expiration that prevents
aspiration and promotes
the removal of secretions
and foreign particle from
lung.
- causes
- Acute
- Inhaled foreign body
- Respiratory tract infection
- Chronic
- either
- Productive
- Blood stained
- Lung cancer
- Pulmonary embolism
- TB
- purulent
- COPD
- Bronchiectasis
- pink, frothy
- Pulmonary edema
- or
- Non-productive
- Asthma
- Postnasal drip
- GERD
- Drugs (ACE inhibitors)
- Sarcoidosis
- later diagnosed with
- Pneumonia
- Definition
- Pneumonia is inflammation of the lung parenchyma
- resulting in
- consolidation
- due to
- exudate within lung tissues and airspaces.
- classifications

- Infective
- Mycoplasmal / Chlamydial
- Tuberculosis
- Fungal
- Bacterial
- Viral
- Non-infective

- Duration
- either
- Acute
- or
- Chronic
- causative agents
- Histoplasmosis
- Blastomycosis
- Coccidioidomycosis
- Morphological types
- include
- Lobar
- Characteristics
- 90% strept pneumonea
- Other organism; Klebsiella
in extremes of ages, DM)
- High fever, cough with
sputum, pleuritic chest pain
- 4 stages
- Congestion (24 hr)
- Red hepatization (48 hr)
- Gray hepatizaiton (96 hr)
- Resolution (8days)
- Few macrophages, normal
- Neutrophils & Macrophages
- Exudation +RBC
- Vasodilatation→ congestion.
- Middle age (20 - 50)
- Primary in healthy individuals
- Common in males
- Entire lobe consolidation
- Limited by anatomic boundaries
- Usually unilateral
- Interstitial pneumonitis
- Bronchopneumonia
- Extremes of age
- Secondary
- Both genders
- Patchy consolidation
- Not limited by anatomic boundaries
- Usually bilateral
- Characteristics
- Staph, Strept and H. Influenza
- Suppurative inflammation
filling bronchi, bronchioles and
alveoli
- 4 stages
- Clinical Setting
- include
- Primary or Secondary
to another disease
- Aspiration pneumonia
- characteristics
- usually occurs in
- unconscious patients
- prolonged bedrest
- Alcoholics
- Mostly affects posterior
lobes, especially the superior
segments of the lower lobes
- Often lead to abscesses
- In immunocompromised patient
- Causative agents
- Pneumocystis jrovecii
- Cytomegalovirus
- Fungi
- Hospital-acquired
(nosocomial)
- or
- Community-acquired
- could be
- Atypical
- causative agents
- viral
- mycoplasma pneumoniae
- chlamydia
- Unlike in "typical"
acute pneumonias
- Sputum production is modest
- No physical findings of consolidation
- WBC count is only moderately elevated
- Bacteria could not be isolated
- Typical
- Causative agents
- streptococcus pneumoniae
- haemophilus influenzae
- moraxella
- staphylococcus
- klebsiella pneumoniae
- pseudomonas aeruginosa
- legionella pneumophilia
- Occurs in patients with
debilitation or have
catheters or are on
ventilators
- causative agents
- MRSA, P. aeruginosa, Klebsiella,
E. coli, S. pneumonia, H.
influenza
- Treatment
- complications
- Respiratory distress
- Pleural effusion
- Empyema
- Lung abscess
- Atrial Fibrillation
- investigations
- Chest X-ray
- CBC
- Arterial blood gas
- Serum electrolytes
