Catherine Buchan is a pulmonologist based in Prahran, VIC. She works from Level 6, 99 Commerical Rd, Prahran, VIC 3004, Australia. Her clinic focus is on breathing and sleep-related problems, especially when weight and oxygen levels get involved.
Day to day, Catherine helps people who have Obstructive Sleep Apnoea (OSA) and Obesity Hypoventilation Syndrome (OHS). These can both affect sleep, energy, and breathing overnight. In many cases, the goal is to make night-time breathing safer and easier, and to help people feel more rested during the day.
Breathing issues don’t always stay limited to sleep. Catherine also looks after patients with Chronic Obstructive Pulmonary Disease (COPD). COPD can cause ongoing shortness of breath, ongoing cough, and flare-ups that come and go. Over time, people can feel like their breathing is getting harder, and it can be stressful. Having a clear plan for day-to-day lung health matters a lot.
Sometimes the breathing problem is linked to lower oxygen in the body, which can show up as Cerebral Hypoxia. That’s when the brain doesn’t get the oxygen it needs. At times, this can be connected to sleep breathing problems or long-term lung and breathing conditions. Catherine’s approach is practical and calm, focusing on understanding the pattern of symptoms and what might be driving them.
Obesity is also part of the picture in Catherine’s work. Weight can change how breathing works, both during sleep and while awake. Catherine helps people sort through what’s going on and what steps could help, rather than treating the problem as one simple thing.
