resp Flashcards
Signs of CO2 retention
dizzieness, flap, headache, tired, confused,
describe a blue boater
not breathless and cyanosed.
Rely on oxygen to stimulate respiratory effort as insensitive to CO2
Usually have cor pulmonale
Blood gas will show type 2 resp failure (CAREFUL with oxygen therapy)
Chronic bronchitis
describe a pink puffer
sensitive to CO2 - low CO2 increased resp rate and heart rate, using resp muscles usually not cyanosed thin type 1 resp failure Emphysema
What are the stages of COPD
- 80% FEV
- 50-80% FEV
- 30-40% FEV
- <30% very serious
WHat is the treatment for COPD >50%
- SABA or SAMA
- SABA/ SAMA + LABA/LAMA (cant have LAMA + SAMA)
- SABA/ SAMA + LABA/LAMA + ICS
- SABA + LABA + ICS + LAMA
What is the treatment for COPD <50%
- SABA or LAMA
- SABA/LAMA + LABA + ICS
or SABA + LAMA + ICS - SABA + LABA + LAMA + ICS
other treatments for COPD
oral theophyline pulmonary rehabilitation mucolytics nutritional supplements long term home oxygen therapy
criteria for home oxygenation
<92 dats on air, FEEV <30, cor pulmonale, polychthaemia
Management of acute COPD in hospital and community
Community: 30mg pred 7-14 days. oral Abx if ? pneumo, safety net 6 weeks and optimise treatment once stable
Hospital: oxygen titrated , can have IV Abx, salbutamol nebs, ipatropium nebs, PO pred, sputum culture and CXR, theophyline, bloods ECG,
- Theophylline level at admission (if the person is on theophylline)
last line bipap
Causes of bronchiectasis
- TB pneumonia flu SLE, RA, Marfans (connective tissue disorders) - A1at, CF - tumour - immune deficiencies e/g
Management of bronchiectasis
- Stop smoking
- Physiotherapy
- Postural drainage
- Antibiotics for exacerbations
- Immunisations
- Bronchodilators
Management of CF
- Physiotherapy, bronchodilators and antibiotics, antibiotics (same as bronchiectasis)
- Mucolytics
- airway clearence devices
- lung transplant if resp failure
- creon, ADEK vits
- liver transplant if cirrhosis
- fertility counselling and genetic counselling
- treatment of DM
Criteria for HAP
develops >48h after admission
OR thats gone home but been hospitalised >10 days previously
WHich organisms predispose to CAP
- s pneumo, Hib
- Mycoplasma, chlymidia, legionella
- influenza and parainfluenza
Which organisms predispose to HAP
- Klebsienna, S. aureus, Pseudomonas, enterobacteria
How do you investigate suspected pneumonia
- FBC, CRP, U+E, LFT
- CXR
- Sputum sample
- Urine (legoinella)
- PCR (mycoplasma and chlymidia)
- Serum IgM (mycoplasma)
- Blood cultures
How do you treat CURB 1-3
How does the treatment change if aspiration is considered
0/1 = oral amoxicillin OP 2 = oral amoxicillin + clarithromycin Inpatient 3 = IV clarithromycin and IV co-amoxiclav inpatient 10 days
Follow up Xray 6 weeks!!
Aspiration? metronidazole
How do you manage HAP
mild = oral doxycycline severe = oral co-trimoxazole
Follow up X ray 6 weeks!!
Complications of pneumonia
abscess, effusion, empyema, bronciectasis, sepsis, collapse
Difference between lobar pneumonia and bronchopneumina
Lobar pneumonia - alveoli, CAP organisms
Bronchopneumonia - patchy, Old/ immunosuppressed/ ill, can cause BE/ fibrosis/ empyema
