Respiratory Simulation Specialists

Who We Help


Respiratory simulation helps advance the design, manufacture, and testing of respiratory devices that are ever more user-friendly, safe, and able to meet the challenges faced by medically complicated patients. Engineers have been a key user group for IngMar Medical from our inception.

Our ASL 5000™ Breathing Simulator is a digitally controlled, high fidelity breathing simulator capable of simulating neonatal though adult patients. Because of its accuracy, flexibility and precision, the ASL 5000 has established itself as an essential instrument for product development and quality control in the respiratory device industry, including ventilators, CPAP and aerosol drug delivery devices. Research studies using the ASL 5000.

ASL 5000 Accuracy
