Abstract:
Cardiac surgery has been evolving to include minimally invasive, hybrid and transcatheter techniques. Increasing patient age and medical complexity means that critical care management needs to adapt and evolve. Recent advances have occurred in several areas, including ventilation, haemodynamics and mechanical circulatory support, bleeding and coagulation, acute kidney injury, and neurological management. This narrative review describes standard care, recent advances, and future areas of research in the critical care management of patients undergoing cardiac surgery.

Critical Region, Critical Values and Significance Level
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...
