Q

Dyspnoea considerations

A

Nasal and naso-pharyngeal considerations: rhinosinusitis- acute and chronic, post nasal drip; viral upper respiratory tract infection
Tracheo-bronchial considerations: asthma; COPD (usually associated with smoking); bronchiectasis (scarring from previous infection or as part of other conditions - CF), dilation of smaller airways forming potential space for mucous pooling, stagnation and infection, lower threshold for antibiotics, and longer course, consideration of colonisation; cancer (bronchogenic carcinoma, SCLC small cell lung carcinoma, usually environmental)

Q

Breathlessness and Hyperventilation

A

Breathlessness: causes are often multi-factorial (cardiac failures arise as complication of COPD, asthmatics may get pneumothorax)
Hyperventilation: significant proportion of chronic SOB, management includes reassurance, rebreathing and relaxation
