Presenting the case – for public forum
Intensive Care Unit (ICU)

This will be presented as a case scenario:
A BE graduate enters our hospital Emergency Room (ER) at 5.00pm and says his brother, Mr.X, 55years of age felt giddy and fell down at home. He had taken him to a nearby doctor who advised Mr.X to be admitted in an ICU (Intensive care unit). So he asked the Emergency Room doctor, what is meant by ICU for this the Emergency Room (ER) doctor said, I will explain in detail about ICU.
Intensive Care Unit is also called as Critical Care Unit (CCU), Intensive Therapy Department (ITD).
ICU’s are specialized wards in hospitals. Specialized ward means, a ward which has special equipments and where highly specialized care of treatment and monitoring will be given to patients who suffer from serious illness, who are seriously ill, who are in an unstable condition or who suffer from serious injury.

History of ICU

The ICU’s roots can be traced back to the Monitoring Unit of critical patients in the Crimean War which began in 1853 .Because of the lack of critical care and the high rate of infections, there was a high mortality rate of hospitalised soldiers, reaching as high as 40% of the deaths recorded during the war. Nightingale and 38 other volunteers had to leave for the Fields of Scurati, and took their “critical care protocol” with them. Upon arriving, and practicing, the mortality rate fell to 2%. This formed the basis of importance of Intensive Care setting to this date.
