John R. Wheatley is a pulmonologist in Westmead, NSW, Australia. He works with people who have breathing and lung-related conditions, as well as some health issues that link closely with how well the body is getting oxygen during sleep and illness.
In many cases, patients see him for long-term lung problems like chronic obstructive pulmonary disease (COPD) and interstitial lung disease. He also looks after people who may have pulmonary hypertension, where the blood pressure in the lungs is higher than it should be. When things change quickly, he can also help with more sudden issues such as acute interstitial pneumonia.
Sleep can be part of the picture too. Obstructive sleep apnoea is one of the conditions he supports, along with drowsiness and excessive daytime sleepiness. These aren’t just “tiredness”. They can affect concentration, mood, and day-to-day safety, so getting the cause checked matters.
John also cares for patients with cystic fibrosis, and at times he helps people dealing with cerebral hypoxia and related oxygen issues. Hypertension is listed as part of his service mix as well, which reflects how closely lung health and overall blood pressure can connect for some people.
His experience is in caring for adults dealing with a mix of ongoing lung disease and sleep-related breathing problems. Specific numbers or years of practice aren’t shown on this profile, but the range of conditions listed gives you a sense of the type of work he does.
Education details aren’t provided here, but you can expect care based on standard medical training for respiratory specialists. Research and publication details aren’t listed on the profile either, so there isn’t much to confirm about studies. Clinical trials are also not described here, so any involvement would need to be checked directly with the practice.
Overall, the focus is on practical help—sorting out what’s driving symptoms, making a clear plan, and supporting patients through both long-term management and times when breathing issues flare up.
