CASOS Y PATOLOGÍAS
VENTILATION MODES:
- Volume Control: through this ventilation mode the user can define the tidal volume administered to the patient. The airway pressure results from the compliance of the lungs, airaways resistances and the inhaled volume.
- Pressure Control: using this ventilation mode the user can define the inspiratory pressure which is administered to the patient’s lungs.
- Pressure Support: using this assisted ventilation mode, that is patient-triggered (by pressure or airflow), the user can set the ventilator simulator to provide assistance when the patient makes a breathing effort. In this ventilation mode the trigger threshold represents a critical setting; actually an incorrect value of this parameter can produce the so called missed triggering phenomenon.
- APRV: this ventilation mode is a form of CPAP which utilises releases of the high pressure level to a low pressure level intermittently and so it allows the administration of inverse ratio ventilation. In this modality, the patient has the freedom to make unassisted spontaneous breaths.
CONTROLABLE PARAMETERS:
- The user interface allows also the user to directly change the ventilation settings (as the Positive End-Expiratory Pressure, the Respiratory Rate or the Tidal Volume) and to see on the virtual ventilator monitor several output parameters updating in real time (like Fraction of Inspired Oxygen, Insp : Esp Ratio, Expiratory Minute Volume, Inspiratory Minute Volume, Drive Pressure Value, etc.) and waveforms (like Pressure, Volume, Flow, Volume – Pressure loop, Flow – Pressure loop, Flow – Volume loop etc.).
- The instructor is able to change the value of the parameters like the Lung Compliance, Thorax Compliance, Resistances, Respiratory Muscle Effort that describe the patient charachteristics and this will clearly affects the Respiratory Rate, the Inspiration Time, the Oxygen saturation, the End-Tidal CO2 and the Arterial Pressure of the high-fidelity simulator.
