Critical Care

Septic shock is a severe response to infection that dangerously impairs circulation. It can lead to organ failure and needs urgent treatment of infection and circulatory disturbance.

Acute respiratory failure means the lungs cannot supply enough oxygen or remove carbon dioxide adequately. Breathing support may be required while its cause is treated.

Multi-organ dysfunction involves failure of two or more organ systems during severe illness. Several organs may need support while the trigger is addressed.

Severe pneumonia may cause respiratory failure requiring mechanical ventilation. A ventilator supports breathing while the infection and its complications are treated.

Post-operative critical care monitors breathing, circulation and organ function after major or high-risk surgery. It also helps identify surgical complications early.

Acute kidney injury during critical illness can result from low blood flow, sepsis or medicines. Urine output, blood chemistry and fluid balance guide care.

Severe trauma may cause hidden bleeding and unstable circulation. Intensive observation detects deterioration after initial emergency treatment.

Diabetic ketoacidosis is acidic ketone build-up from insulin deficiency. Other metabolic emergencies may involve extreme glucose or electrolyte changes affecting consciousness and organs.

After resuscitation from cardiac arrest, patients need close monitoring of brain function, rhythm and circulation. The cause of the arrest also needs investigation.

Prolonged ventilator weaning means difficulty stopping breathing-machine support. Lung disease, muscle weakness and other complications may require a gradual monitored recovery.
