Mechanical ventilation provides breathing support for patients who cannot maintain adequate oxygenation or ventilation independently. It may be required during severe respiratory failure, critical illness or after major surgery. Ventilator settings are adjusted according to lung function, blood gas measurements and the patient's response to treatment.
Advanced airway management involves techniques used to maintain a safe and effective breathing passage in critically ill patients. Procedures may include endotracheal intubation and other specialised airway interventions. These techniques are considered when patients experience respiratory failure, reduced consciousness or an inability to protect their airway.
Sepsis is life-threatening organ dysfunction caused by an abnormal response to infection. Symptoms may include fever, confusion, rapid breathing and low blood pressure. Treatment requires prompt clinical assessment, appropriate antimicrobial medication, fluid management and support for affected organs. Severe cases require intensive care monitoring.
Septic shock is a severe form of sepsis involving persistent circulatory abnormalities and an increased risk of organ failure. Treatment may involve intravenous fluids, antibiotics, vasopressor medicines and continuous haemodynamic monitoring. Identifying and controlling the source of infection is an important part of management.
Haemodynamic monitoring evaluates blood circulation, blood pressure and cardiovascular function in critically ill patients. Monitoring methods may include arterial blood pressure measurement, cardiac ultrasound and selected invasive techniques. Findings help guide fluid therapy, medications and interventions intended to maintain adequate circulation to vital organs.
Multi-organ dysfunction syndrome occurs when two or more organ systems become severely impaired during critical illness. It may affect the lungs, kidneys, heart, liver or brain. Management requires identifying the underlying cause, monitoring organ function and providing appropriate respiratory, circulatory or other organ support.
Cardiac critical care focuses on patients experiencing severe cardiovascular conditions requiring intensive monitoring and treatment. These may include cardiogenic shock, dangerous heart rhythm disturbances or complications following cardiac procedures. Management depends on the diagnosis and may involve medication, respiratory support and specialised cardiovascular interventions.
Postoperative intensive care provides close monitoring for patients recovering from major surgery or experiencing surgical complications. Care may include respiratory assistance, pain management, circulatory monitoring and infection prevention. The duration and intensity of support depend on the patient's medical condition and postoperative recovery.
Diabetic ketoacidosis is a serious metabolic complication caused by insufficient insulin, resulting in elevated ketone levels and blood acidity. It requires urgent hospital treatment, including intravenous fluids, insulin, electrolyte correction and monitoring. Clinicians also investigate contributing factors such as infections or missed insulin doses.
Hyperosmolar hyperglycaemic state is a severe diabetes-related emergency involving extremely high blood glucose and substantial dehydration. It can affect consciousness and organ function. Treatment involves careful fluid replacement, electrolyte monitoring, insulin when appropriate and management of the underlying cause.
Neuro-trauma critical care supports patients with serious brain or spinal injuries. Management focuses on maintaining adequate oxygenation, circulation and neurological function while preventing secondary injury. Treatment may involve respiratory support, neurological monitoring, imaging investigations and collaboration with neurosurgical specialists.
Critical care echocardiography uses ultrasound to assess heart structure and function in seriously ill patients. It can help evaluate cardiac pumping ability, fluid-related findings and certain circulatory abnormalities. Results are interpreted alongside blood pressure, clinical examination and other monitoring parameters to guide intensive care decisions.
Point-of-care ultrasound is a bedside imaging technique used to answer focused clinical questions in critically ill patients. It can help evaluate the heart, lungs, abdomen and vascular structures. Findings support rapid clinical assessment but must be interpreted alongside other examinations and investigations.
Acute respiratory failure occurs when the lungs cannot provide sufficient oxygen or adequately remove carbon dioxide. Causes include severe pneumonia, lung injury and other critical illnesses. Treatment may involve oxygen therapy, non-invasive ventilation, mechanical ventilation and management of the underlying disease.
