Modelling of the fluidic systems, parameters and properties of the fluidic models. Principles and adverse effects of artificial lung ventilation (ALV). Conventional and unconventional lung ventilation, corresponding ventilators. Equipment for anaesthesia. Anaesthetic vaporisers, their thermodynamic principles. Humidification of ventilatory gases. Equipment for monitoring and support of blood circulation. Dilution methods. Bed-side monitors. Other diagnostic and therapeutic equipment at ICU and ACCM. Design of ICU and ACCM.


Assessment requirements:

Active lab attendance including pre-lab homework. All lab exercise assignments submitted by the following lab session.


The final exam is closed-book, made of a written test based on the content of lectures and laboratory exercises including assigned individual study and home preparation.

The mid-term exam is closed-book, made of a written test based on the content of lectures and laboratory exercises before the week of the exam (including assigned individual study and home preparation).

Grading according to the ECTS scale (100 points at most):

Lab Assignments: 5%

Mid-term test: 15%

Final exam: 80%

Study Objective:

The aim of the subject is to give the students overview of the basic equipment of the intensive care units or departments of anaesthesia and critical care medicine. It involves life-supporting devices, especially for artificial lung ventilation, monitors of the patient's physiologic parameters, equipment for anaesthesia, etc.
