Patients receive air based on their personalized ventilation parameters (pressure, respiratory rate, volume, etc.). An intelligent metering-controlling-mixing-air management system near the patient is responsible for personalized patient ventilation. Due to the modularity of the system, new patients can be integrated into the system without having to stop ventilating already connected patients.
The ventilator system is divided into larger segments, which include closures (both in the exhalation and inhalation subsystems). Segment locks serve as gates that, when opened, can deliver air to another segment under specific pressure conditions.
The system provides several options for adjusting the O2 concentration of each patient: oxygen delivery can be achieved by concentration-based or even time-based control. Thanks to the mechanical flow controller, the amount of O2 introduced does not depend on the difference in pressure in the O2 supply system and in the patient zone; it depends only on the time period of delivery. In flow control mode, a predetermined amount of ambient air is supplied so that the required O2 can be calculated accurately. In pressure control mode, depending on the patient’s condition and parameters (which may change over time), different amounts of ambient air can be injected so that the required additional O2 concentration (the difference between two cycles) is calculated using the O2 quantity of the previous breathing cycle.
The temperature and humidity of the air supplied to the patient can be regulated in several places in the system. At the patient’s mouth, it is possible to set the desired values with passive (e.g., HME – Heat and Moisture Exchangers) or active solutions (e.g., HME Booster).
