About Dr David McKenzie
Dr David McKenzie is a Respiratory Medicine specialist in Randwick, NSW, Australia.
Respiratory (Pulmonary) medicine concerns the diagnosis and treatment of diseases and disorders affecting the lungs and breathing. A range of conditions affect the respiratory system. Common problems include asthma , involving inflammation of the bronchi, which makes them swell, narrowing the airways. Sleep apnoea is characterised by a reduction or pause of airflow during sleep. Chronic obstructive pulmonary disease (COPD) is any disorder that persistently obstructs bronchial airflow. COPD mainly involves two related diseases: chronic bronchitis and emphysema.
