Peter A. Cistulli is a pulmonologist based at Royal North Shore Hospital in Sydney, NSW, Australia. He looks after people where breathing, sleep, and daytime tiredness can link together. If someone has ongoing breathing problems at night, poor sleep, or feels very sleepy during the day, this is the kind of care he helps with.
Sleep issues are a big part of his work. That can include obstructive sleep apnoea, central sleep apnoea, and irregular sleep-wake patterns. He also supports people with insomnia, drowsiness, and excessive daytime sleepiness. For some patients, weight and breathing are closely tied, so conditions like obesity and obesity hypoventilation syndrome may come up in care plans.
Breathing health in the lungs also matters. He works with adults living with chronic obstructive pulmonary disease (COPD), and he helps manage day-to-day problems where breathing can affect how someone feels and functions. At times, breathing concerns can also connect to wider health issues, including heart conditions. This can include heart failure, high blood pressure, coronary heart disease, and even situations like acute coronary syndrome. In some cases, blood oxygen levels and cerebral hypoxia are part of the bigger picture, which is why careful monitoring is important.
Peter also works with people who have rarer syndromes that can affect sleep and breathing. That includes Ehlers-Danlos syndrome (EDS), Marfan syndrome, and SHORT syndrome. There are also mentions of ADULT syndrome and vasoconstriction in his scope, along with type 2 diabetes. When these conditions are present, sleep and breathing problems may not be straightforward, so getting the right tests and support can take time.
Details about his experience and education are not listed here, so it’s best to check with the clinic if you want specifics. What is clear, though, is that he cares about practical outcomes—helping people breathe better, sleep better, and feel safer in their everyday life.
Research and updates in treatment can be important in sleep and lung care, especially as new options and technologies keep coming through. Clinical trials information isn’t included here, but if you’re interested in trial studies, the hospital team can usually tell you what’s available and what might suit your situation.
