Q

Pathology of asthma?

A

o Usually reversible either spontaneously or treatment
o 1. Airway narrowing
 Smooth muscle contraction, thickening of airway wall by cellular infiltration and inflammation
 Secretions within the airway
o 2. Inflammation
 Mast cells, eosinophils, T cells, dendritic cells cause IgE production and release of histamine, prostaglandin D2, leukotriene C4
o 3. Remodelling
 Hypertrophy and hyperplasia leading to more mucous secreting goblet cells

Q

When should you not discharge patient with pneumonia?

A

o Do not discharge if 2 or more of following:

 Temperature >37.5, RR >24, HR>100, BP <90, O2 <90%ora, abnormal mental status, unable to eat or drink

91
Q

Follow up advice for patient after pneumonia?

A

o CXR at 6 weeks if symptoms persisting despite treatment or high risk of underlying malignancy (smokers or people over 50)

92
Q

Complications of pneumonia?

A 
o	Pleural effusion
o	Empyema
o	Lung Abscess
o	Respiratory failure
o	Sepsis
o	Pericarditis
o	AKI
93
Q

Oxygen management - 1 - critically ill requiring O2?

A

15L/min via Non-rebreathe (Reservoir) mask

Once stable - reduce oxygen dose and aim 94-98%

COPD - same initial target sats - measure ABG and move to controlled oxygen if needed

94
Q

Oxygen management - 2 - serious illness requiring moderate if patient hypoxic?

A

Initial O2 - 2-6L/min nasal cannula or 5-10L/min via facemask

If O2 <85% - 15L/min via non-rebreathe mask

Aim 94-98%

95
Q

Oxygen management - 3 - COPD and other conditions requiring controlled oxygenation?

A

Use 28% Venturi aiming 88-92% until ABG available

If CO2 raised or Hx of IPPV/NIV then continue 88-92%, if not then aim 94-98%

If high O2 sats - reduce dose of O2

Recheck ABG within 60 minutes or earlier if deterioration - if pH<7.35, H >45, PCO2 >6.0 - senior for NIV or ventilation

96
Q

Indications for NIV?

A

Respiratory acidosis - pH<7.35 or PCO2>6.0

In people with COPD, respiratory muscle weakness, chest wall deformity, obesity hypoventilation

97
Q

Difference between CPAP and NIV/BiPAP?

A

CPAP - does not reduce CO2 - don’t use in T2RF

NIV/BiPAP - difference between IPAP and EPAP increases patients tidal volume and decreased arterial CO2
