Adult Lung Simulators TestChest

TestChest is "very impressive in terms of physiological reality -- especially spontaneous breathing" says Dr. Lise Piquilloud, PD & MER, Médecin associée, CHUV, Lausanne, Switzerland.

Autonomous lung simulator

Autonomous lung simulator

TestChest® was developed to simulate the human heart and respiratory system for teaching and training purposes. It can be used either as a stand-alone skill training station or integrated into a full-scale patient simulator.

Compatible with full-size mannequins

Compatible with full-size mannequins

TestChest turns any existing mannequin into a physiological lung simulator because TestChest has an airway opening that can be fitted to any mannequin or single head device. Make use of the combined features of mannequins and the outstanding physiology of TestChest. Contact AQAI GmbH in Germany for integration with Laerdal SimMan.

Works with all ventilators

Works with all ventilators

TestChest can be connected to all ventilators, for intubated patients as well as mask ventilation. All modalities are possible: pressure-volume maneouvres, recruitment, PEEP adjustment, expiratory trigger sensitivity, pressure control, assist control, volume control, SIMV, PAV, adjustment, APRV, PSV, CPAP, PRVC, ASV, Intellivent and all other modalities.

Creates outcome

Creates outcome

Whatever you set as a patient, the result of the treatment provided by the student will show on airway pressures, lung volume, arterial oxygen saturation, end-tidal CO2, and more. Outcome is not created by the operator but by the interaction between student and TestChest, in real-time and reproducibly. New forms of interactive learning are possible: submit the same case to different students and let them compete on outcome in a safe environment.

Operator control panel

Operator control panel

The basic operator panel offers the selection of the pre-configured patients and the degree of breathing activity. Changes from ARDS to airway obstruction and all concommitent physiological changes are done a the click of a button. Spontaneous activity can be added if needed, e.g. to put a patient to sleep or to wake him/her up. You can easily extend the selection of patients and program your own patient library by clicking on "More" (password protected). Further details are provided in the Operator's Manual.

Robust design

Robust design

Housed in a metal sheet enclosure, two rubber bellows are driven by a linear motor who is able to produce pressures higher than 100mbar. Two steel rods guide the lung assembly which is powered by two independent power supply modules. Ultra-low maintenance and Swiss Quality reliability secure your investment.
