Critical care assessment involves the rapid evaluation of patients with serious or life-threatening illness. Doctors assess breathing, circulation, consciousness and organ function to identify immediate risks. Stabilisation may require oxygen therapy, intravenous fluids, medication, continuous monitoring and advanced organ support. Treatment is coordinated according to the patient's underlying condition and clinical response.
Mechanical ventilation supports patients who cannot breathe adequately because of severe respiratory failure or other critical illnesses. Ventilators help deliver oxygen and remove carbon dioxide through a breathing tube or suitable non-invasive interface. Ventilation settings are adjusted according to respiratory function, blood gas results and clinical progress.
Renal replacement therapy supports patients whose kidneys cannot adequately remove waste products or regulate fluid and electrolyte balance. In critically ill patients, continuous renal replacement therapy may be considered when conventional dialysis is unsuitable. Treatment decisions depend on kidney function, metabolic abnormalities, fluid status and overall clinical stability.
An intra-aortic balloon pump is a mechanical circulatory support device used in selected patients with serious cardiovascular conditions. The balloon inflates and deflates in coordination with the heartbeat to support coronary circulation and reduce cardiac workload. Its use requires specialist assessment, continuous monitoring and careful management of potential complications.
Intracranial pressure management involves monitoring and treating increased pressure within the skull, which may occur after traumatic brain injury, bleeding or other neurological conditions. Treatment aims to protect brain function and maintain adequate blood circulation. Management may involve physiological monitoring, medication, ventilation adjustments and coordinated neurosurgical assessment.
ECMO is an advanced life-support technique that temporarily supports the lungs or heart in selected patients with severe organ failure. Blood is circulated through an external system for oxygenation and carbon dioxide removal. ECMO requires a specialised multidisciplinary team, continuous monitoring and careful assessment of treatment risks and potential benefits.
Ultrasound-guided vascular access uses real-time imaging to help clinicians locate blood vessels during catheter insertion. It is commonly used in intensive care when reliable intravenous access is required for medication, monitoring or organ support. Ultrasound guidance may improve procedural accuracy and help reduce selected insertion-related complications.
Central venous catheterisation involves placing a catheter into a large vein to administer certain medications, provide reliable vascular access or support specialised monitoring. The procedure is frequently required in critically ill patients. Safe insertion involves sterile technique, appropriate site selection and monitoring for infection or mechanical complications.
Pulmonary artery catheterisation is an invasive monitoring procedure used in selected critically ill patients with complex cardiovascular conditions. The catheter provides measurements that may help assess blood flow and pressures within the heart and pulmonary circulation. Its use depends on clinical indication, available expertise and careful consideration of associated risks.
Bronchoscopy uses a flexible camera to examine the airways and assist with selected diagnostic or therapeutic procedures. In intensive care, it may help assess airway obstruction, obtain respiratory samples or remove certain secretions. The need for bronchoscopy depends on respiratory findings, patient stability and the expected clinical benefit.
Tracheostomy creates an opening in the front of the neck to provide access to the windpipe through a specialised tube. It may be considered for patients requiring prolonged mechanical ventilation or specialised airway management. The decision involves assessment of respiratory needs, expected recovery and procedural risks.
Chest drain insertion involves placing a tube into the pleural space to remove accumulated air or fluid. It may be required for pneumothorax, certain pleural effusions or other serious chest conditions. The procedure is performed with appropriate monitoring, imaging guidance when indicated and attention to potential complications.
Advanced airway management includes techniques used to maintain a clear airway and support breathing in patients who cannot protect or maintain their airway independently. Procedures may include endotracheal intubation and assisted ventilation. The approach depends on the patient's condition, airway anatomy and urgency of intervention.
Cardiac critical care focuses on patients with serious cardiovascular conditions requiring continuous monitoring and advanced treatment. These may include severe heart failure, cardiac complications following surgery and circulatory instability. Management can involve medication, haemodynamic monitoring, ventilatory support and selected mechanical circulatory support techniques.
Trauma critical care supports patients with severe injuries that may affect multiple organs. Treatment priorities include maintaining breathing and circulation, identifying internal injuries and preventing complications. Care may require blood products, mechanical ventilation, organ support and coordinated treatment with trauma surgeons and other specialists.
Neurocritical care involves intensive monitoring and treatment of patients with serious neurological conditions, including traumatic brain injury, major brain haemorrhage and complications following neurosurgery. Management focuses on protecting brain function, maintaining physiological stability and identifying neurological deterioration. Treatment is coordinated with neurology and neurosurgical teams.
