Dwayne L. Mann is a pulmonologist based in Brisbane, QLD, Australia. He works with people who struggle with breathing during sleep and with ongoing daytime tiredness. Sleep can affect so much more than people realise, and when it goes off track, it often shows up as fatigue, poor focus, and feeling worn out.
In his clinic, Dwayne looks after patients dealing with obstructive sleep apnoea and central sleep apnoea. These are both conditions where breathing can pause or become uneven during sleep. Over time, that can break up sleep and leave the body short on the oxygen it needs. For some people, this links with cerebral hypoxia, where the brain does not get enough oxygen during episodes at night.
Many referrals are for drowsiness and excessive daytime sleepiness. This might be someone who keeps nodding off, feels sleepy after a full night’s sleep, or finds it hard to stay alert at work or while driving. At times, it can also show up as irritability or just a general “can’t switch off” feeling. Dwayne helps patients make sense of what is going on and maps out practical next steps.
He also supports families where sleep concerns are part of Down syndrome care. Sleep issues are common in this group, and they can affect energy levels, mood, and day-to-day functioning. Getting the sleep side right can make a real difference, and it often helps the whole family feel more settled.
Because these conditions can be different from person to person, the focus stays on the person in front of you, not a one-size-fits-all plan. Treatment and monitoring depend on what’s happening during sleep and how it lines up with symptoms. In many cases, it is about improving sleep quality and breathing stability, then checking progress over time.
Research can be part of how doctors keep up with what works best, but there is no specific public detail here about research projects. The same goes for clinical trials—there is no specific trial information listed at the moment. What is clear is that Dwayne’s work centres on breathing-related sleep health, helping people breathe better at night and feel more awake in the day.
For anyone in Brisbane who has ongoing tiredness, snoring concerns, or sleep apnoea symptoms, Dwayne Mann provides calm, focused care in a busy everyday setting.
