With TestChest, Organis GmbH created an innovative full physiologic artificial lung that provides a breakthrough in mechanical ventilation training. TestChest promotes a safe and controlled environment free from risks of the clinical environment and eliminates the necessity of training on animals.
Unique simulation features
TestChestÂ® has unique features in terms of representing complex breathing patterns through programmable driving pressure (p0.1) and respiratory rate. Muscular activity, important criteria for weaning, can be easily simulated.
TestChestÂ® has variable resistance and its inspiratory compliance is a non-linear function that can be represented as S-shape curve.
TestChestÂ® has a programmable FRC and allows the simulation of lung collapse and recruitment as well as hysteresis of the pressure-volume loop.
TestChestÂ® realistically replicates gas exchange and hemodynamic responses.
The communication with TestChestÂ® is effectuated via standard TCP/IP network connections. TestChestÂ® includes a user interface software that runs on any windows PC to be connected via Ethernet interface to the simulator.
Â• Selection of preconfigures patients scenarios.
Â• Selection of preconfigured spontaneous breaths.
Â• Calibration procedure.
Â• Setting of parameters for beginners and advanced users.
Â• Storing new patientsÂ’ scenarios and saving the records in a CSV file.
Calibration on national standards
The calibration TestChestÂ® is based on national standards due to the detachable calboard module. The latter contains alveolar, airway, and ambient
pressure sensors as well as a temperature and oxygen sensors. A mass flow controller for CO2 delivery, programmable dead space and leakage are available.
Accurate for years of use
TestChestÂ® consists of two bellows driven by a linear motor. The large volume ensures a realistic replication of vital capacity and FRC of an ICU
adult patient. TestChestÂ® features a detachable calibration module, which makes it accurate for years of use.
TestChestÂ® is not only limited to training as it is further intended to check the functionalities of ventilators, CPAP devices and other respiratory support devices in laboratories facilities.
