Bio Technology Project Report on ICU Ventilator

This Bio-Technology Project Report on ICU Ventilator is an intensive care unit (ICU) ventilator. An intensive care unit (ICU) ventilator is a machine used to assist or replace the spontaneous breathing of an ICU patient having breathing problems or problem regarding lungs.

While a physician, nurse, or other healthcare professional might use a hand-compressed “bag” ventilator in an intensive care setting, it would be more common to use an automatically controlled ICU ventilator.

ICU ventilators are used for patients whose condition is critical. This type of ICU ventilator operates according to the ventilation needs of the patient and the oxygen and gas delivery values set on the machine by the caregiver. It can be used for adult, pediatric and neonatal (all three kinds) of patients.

Kinds of Ventilators:

There are two kinds of ventilators modes: (1)-pressure control or support mode and (2)-volume control or support mode. The detail description of Ventilators according to the patient age is available in the report. Later the report defined the functional part of ventilators that are Control unit and Patient unit.

The report provides details about Siemens ventilator SV 300. Siemens ventilator servo 300 is used for all three types of patients. Siemens ventilator servo 900c is used for adult and pediatric patients. Newport ventilator is used only for the neonatal patient.


In this project report, an attempt is made to provide a complete description of ventilators with its kinds and modes. The other modes of ventilators are Pressure Regulated Volume Control, Volume Support, SIMV (Volume Control) + Pressure Support, SIMV (Pressure Control) + Pressure Support, Pressure Support, CPAP (Continuous Positive Airway Pressure) which helps to control that Pressure and Volume of the patient.

Some patients are unsuitable candidates for non-invasive ventilation and for these, invasive mechanical ventilation should be considered, but only after a careful, realistic discussion between the patient, family, and physician.

Regardless of the type of ventilation selected, a conscientious monitoring program that emphasizes good communication and anticipation and prevention of complications is key to success.
