Resp Flashcards
S: Dyspnoea, pink frothy sputum, tachycardia
Sx: bi basal end inspiratory fine crackles , elevated jvp
Acute pulmonary oedema
Paraneoplastic syndromes of small cell carcinoma (5)
Cushingoid Sx from ACTH Lambert-Eaton Syndrome SIADH (low Na high ADH) Encephalitis Retinal blindness
Paraneoplastic syndrome of adenocarcinoma
Hypertrophic pulmonary osteoarthropathy
Paraneoplastic syndrome of squamous cell carcinoma
Hypercalcaemia - PTH like protein secretion
Hyponatraemia
Also associated with central cavitating lesions
Keratinised cells
Most associated with smoking bronchial carcinoma
Squamous cell carcinoma
Small cell to lesser extent
Most common bronchial carcinoma and seen commonly in female non smokers
Markers?
Adenocarcinomas
Tyrosine kinase inhibitors used to treat EGFR and KRAS receptors
Type 1 vs Type 2 Respiratory failure difference
Both have low pO2, below 7.5.
Type 1: V/Q mismatch, hypoxia with normocapnia. Eg PE, pulmonary fibrosis, pneumonia, pulmonary oedema
Type 2: ventilation dysfunction, hypercapnia and hypoxia. Eg asthma attack, COPD, OSA
/ GBS, polio, diaphragmatic paralysis / thoracic wall disease/
Sx and symptoms of hypoxia
Dyspnoea, restlessness, tachypnoea, tachycardia, cyanosis.
Headache, confusion, drowsiness, fatigue, pallor?
Treatment of asthma vs COPD
Asthma: SABA, inhaled corticosteroid, LABA, oral prednisolone
COPD: SAMA/ SABA, LAMA/LABA, theophylline, corticosteroids
Most common CAP pathogens
Streptococcus pneumoniae 50%
Haemophillus influenzae 20%
Chlamydophila pneumoniae 13%
Mycoplasma pneumoniae 3%
Atypical pneumoniae x5
Mycoplasma pneumoniae: younger age group, neuro + systemic signs (rash), joint pain, otitis media, lymphadenopathy
Chlamydia pneumoniae: mild symptoms
Chlamydia psittacosis: parrots, psittacosis
Legionella pneumophila: high mortality rate Legionnaire’s Disease, abdo pain diarrhoea confusion
Coxiella Burnetti : Q fever
Hospital acquires pneumonia : classification/ bugs
> 48 hours admission
Gram negative enterobacteria
Staph aureus
Also: pseudomonas, klebsiella, (ventilator associated) bacteriodes, clostridium
Aspiration pneumonia bugs
Oropharyngeal anaerobes
Streptococcus pneumoniae
Klebsiella
What is curb65 or corb score?
Confusion Urea >9 Respiratory >30 BP systolic <90,diastolic <60 65> age
Corb used to decide hospital admission
Curb65 for hospital admission or ICU
Treatment for mild CAP pneumonia
Amoxicillin with/out doxycycline
