John Harrington is a pulmonologist based in Newcastle, NSW, Australia. He works with people who have breathing problems, especially when the cause is linked to inflammation in the airways and lungs.
In many cases, his patients are dealing with asthma that doesn’t behave the same way for everyone. This can include eosinophilic asthma, where a type of white blood cell called eosinophils is involved. He also looks after conditions like eosinophilic pneumonia and chronic eosinophilic pneumonia, where lung tissue can stay irritated over time. At times, people are also managing hypereosinophilic syndrome or simple pulmonary eosinophilia, which can come with ongoing cough, breathing discomfort, and tiredness.
John’s clinical work can also cover lung infections and other common respiratory issues. That includes bronchitis and pneumonia. He may also be involved when breathing symptoms are connected to hypersensitivity pneumonitis, where the lungs react to things like dust or other triggers.
He also cares for people with obstructive sleep apnoea. Sleep apnoea can affect how you breathe during sleep, and it can lead to daytime sleepiness, poor sleep, and other health issues. When this is part of the picture, it’s often treated as a team problem, with breathing and sleep needs handled together.
This profile doesn’t list years of experience or exact workplace history. What is clear is the focus of his day-to-day respiratory care—looking after people with asthma, eosinophil-related lung conditions, pneumonia and bronchitis, and also sleep-related breathing concerns.
Education details are not listed in this profile. If you’d like to know more about training or qualifications, it may be available through the clinic or during an appointment.
Research and publications aren’t detailed here, and clinical trials information isn’t provided either. Still, if you’re interested in what options might be available for your specific condition, that’s something John can talk through during a consultation.
Overall, his approach fits a straightforward, practical style of respiratory care—taking time to understand symptoms, working out what might be driving them, and helping patients find the next step that makes sense for their lungs and their daily life.
