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.

Requirements:

Assessment requirements:

Active lab attendance including pre-lab homework.

All lab exercise assignments submitted.

At least 15 points from the mid-term exam or lab assignments.

Detailed information on laboratory exercise organization is posted in a special document.

Examination conditions:

The final exam is closed-book, made of a written test based on content of lectures and laboratory exercises including assigned individual study and home preparation. The final test score is included into the total course score if at least a half of the maximum points of the written test is reached.

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

Mid-term exam:15 %

Lab assignments:15 %

Final exam:70 %

Syllabus of lectures:

1. Basic concept or anaesthesia and resuscitation. Basic physiological parameters. Description of a patients status. Importance of circulation, respiration, consciousness and internal environment, their control. Blood gases, their measurement and interpretation. Blood gas analysers.

2. Description of fluidic systems - circulation and ventilation. Mechanical parameters of the biological and technical fluidic systems. Modelling of the fluidic systems, parameters and properties of the fluidic models.

3. Principles and adverse effects of artificial lung ventilation (ALV). Conventional lung ventilation, conventional ventilators.

4. Unconventional regimens of artificial lung ventilation. Unconventional ventilators.

5. Equipment for anaesthesia. Anaesthetic vaporisers, their thermodynamic principles. Humidification of ventilatory gases.

6. Equipment for monitoring and support of blood circulation. Dilution methods of flow rate measurement (thermodilution, LiDCO, PiCCO), pulse oxymetry, bedside monitors.

7. Other diagnostic and therapeutic equipment at ICU and ACCM. Design of ICU and ACCM. Medical gases and their distribution.

Syllabus of tutorials:

1. Introduction, modelling of the respiratory system using electro-acoustic analogy I.

2. Modelling of the respiratory system using electro-acoustic analogy II.

3. Dilution method of flow rate measurement.

4. Heliox and flow-pressure characteristics of fluidic elements. Flow resistance.

5. Frequency dependence of pressure transfer function within the respiratory system.

6. Gas humidification.

7. The influence of the respiratory system disease on lung mechanics.

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.
