Intensive care management involves continuous monitoring and treatment of patients with severe or life-threatening medical conditions. Care may include respiratory support, circulation monitoring, intravenous medications and organ function assessment. Treatment decisions are based on the patient's diagnosis, clinical stability and response to therapy, with multidisciplinary coordination often required.
Emergency critical care focuses on the rapid evaluation and stabilisation of patients with serious illness or injury. Conditions may include severe breathing difficulty, shock, sepsis or sudden organ dysfunction. Management involves identifying immediate threats, providing appropriate life support and arranging further investigations and specialist treatment without unnecessary delay.
Mechanical ventilation supports breathing when a patient cannot maintain adequate ventilation independently. Depending on the condition, treatment may involve a breathing machine connected through an airway tube. Care includes monitoring oxygenation, carbon dioxide levels, lung mechanics and complications, while adjusting ventilation according to the underlying illness.
Non-invasive ventilation provides breathing support through a fitted mask without immediately requiring an endotracheal tube. It may be considered for selected patients with respiratory failure, including certain acute exacerbations of chronic lung disease. Suitability depends on consciousness, breathing effort, gas exchange and the ability to protect the airway.
Sepsis is a life-threatening condition caused by an abnormal response to infection that results in organ dysfunction. Treatment requires timely identification, appropriate antimicrobial therapy, investigation of the infection source and close monitoring. Fluids, medications to support circulation and other organ support may be needed depending on the severity of illness.
Septic shock is a severe form of sepsis associated with persistent circulatory abnormalities and increased risk of death. Patients may require intensive monitoring, antimicrobial treatment, intravenous fluids and medications to maintain blood pressure. Management also focuses on controlling the infection source and supporting affected organs.
Acute respiratory failure occurs when the lungs cannot maintain adequate oxygen levels or remove carbon dioxide effectively. Possible causes include pneumonia, severe airway disease and other serious illnesses. Treatment addresses the underlying cause and may involve oxygen therapy, non-invasive ventilation or invasive mechanical ventilation when clinically necessary.
Acute respiratory distress syndrome is a severe inflammatory lung condition that can develop following infections, aspiration or other major illnesses. It causes impaired oxygen exchange and may require intensive respiratory support. Management focuses on treating the underlying cause, using appropriate ventilation strategies and preventing complications associated with critical illness.
Haemodynamic monitoring evaluates blood pressure, heart rate, circulation and other indicators of cardiovascular function in critically ill patients. Depending on the condition, treatment may include fluid management and medications that support blood pressure or cardiac output. The approach is adjusted according to clinical findings and response to therapy.
Multiorgan dysfunction occurs when two or more organ systems are affected during severe illness. Patients may develop problems involving the lungs, kidneys, heart, liver or nervous system. Intensive care treatment focuses on identifying the underlying cause, supporting affected organs and closely monitoring changes in clinical condition.
Some patients require intensive monitoring after major or complex surgery, particularly when they have significant medical conditions or develop complications. Postoperative critical care may include breathing support, pain management, circulation monitoring and evaluation of organ function. Treatment is coordinated with the surgical and anaesthesia teams.
Severe infections in critically ill patients may require hospital-based antimicrobial treatment, monitoring and support
