Stephen J. Macdonald works in Critical Care Medicine and looks after people who are seriously unwell and need fast, careful care. His practice is based at Level 6, Wellington Street, Perth, WA 6000.
Critical care can look different from day to day. Some patients come in with infections that have turned serious, including sepsis and pneumonia. Others are dealing with sudden health events like a heart attack, acute coronary syndrome, or a stroke, where timing really matters.
Stephen also supports people who are at risk of problems with blood flow and clotting. This can include deep vein thrombosis (DVT), pulmonary embolism (PE), venous thromboembolism (VTE), and other clot conditions like mesenteric venous thrombosis. At times, patients may be facing low blood pressure as part of shock or another acute illness.
There are also emergencies where the body reacts strongly and quickly. For example, severe allergic reactions such as anaphylaxis need prompt assessment and treatment. At the same time, some patients need help when their blood isn’t clotting normally, such as with haemophilia A, or when platelet levels are low and bleeding risk is higher.
In many cases, Stephen cares for people with serious breathing and lung conditions, including COVID-19 and even more severe respiratory illnesses like SARS. He also treats people who have complications that can lead to trouble with oxygen levels and overall stability, not just one symptom on its own.
Over time, critical care patients can also include those dealing with issues like ascites and ongoing bleeding concerns, such as menorrhagia. These can be complicated, especially if they sit alongside infection, clotting problems, or heart and circulation changes.
When someone is in a high-stakes situation, Stephen’s focus stays practical: steady assessment, clear next steps, and careful monitoring as things change. The aim is to help get the body back to safer ground, and to support better outcomes in a tough moment.
