neosim TestChest Artificial Lung to Simulate Mechanical Ventilation

neosim TestChest Lung Simulator

TestChest, developed by neosim, is an innovative full physiologic artificial lung designed for mechanical ventilation training in healthcare providers using clinical simulation. The product was developed to simulate the human heart and respiratory systems for teaching and training purposes. TestChest is versatile and can be used either as a stand-alone skill training station or integrated into a full-scale patient simulator. This HealthySimulation.com article will review the impact the neosim TestChest can have on healthcare learners.

neosim TestChest Artificial Lung

TestChest serves as an autonomous human lung simulator for both paediatric and adults that replicates actual gas exchange and supports compatibility with any non-invasive or invasive ventilator, any make, and any mode (except NAVA). Real-time measurements of SpO2, EtCO2, capnography, and plethysmogram can be recorded on any multipara monitor.

One of the key advantages of neosim’s TestChest is its ability to provide learners with hands-on experience in respiratory therapy concepts without putting actual patients at risk. This allows learners to explore lung mechanics, respiratory control, hemodynamic, and gas exchange through programmable parameters. For instance, learners can simulate different airway resistances, compliance values (individual control of total respiratory compliance, non-linear lung compliance, and chest wall compliance is possible), and breathing patterns, as well as manipulate cardiac output, and create V/Q mismatches. By providing a safe and controlled simulated clinical environment, TestChest facilitates critical thinking and learning from the positive and negative outcomes of interventions.

neosim TestChest provides the learner with experiential learning opportunities to apply concepts of respiratory therapy without risk to human patients. TestChest by neosim is a highly accurate, versatile clinical simulator that represents the premier choice for respiratory care training. Due to its physiological modelling, TestChest can be set to represent any kind of clinical manifestation of pulmonary disease.

This opportunity provides the learners with a vast array of heart and lung physiologies to learn in order to provide the best care to adult and paediatric patients. The respiratory concepts available include:

Lung Mechanics

  • Programmable airway resistance
  • Programmable total compliance and chest wall compliance
  • Non-linear Pv curves
  • Make the lungs more recruitable or non-recruitable

Respiratory Control

  • Choose from a variety of different spontaneous breathing patterns or operator can create specific breathing patterns
  • Programmable inspiratory effort

Haemodynamics

  • Change in cardiac output
  • Create true shunt to create persistent pulmonary hypertension for real-time display of heart-lung interactions

Gas Exchange

  • Change in the work of breathing
  • Programmable diffusion factor
  • Programmable dead space
  • Programmable O2 dissociation curve
  • Create metabolic alkalosis or acidosis

Clinical Simulation Scenario

The clinical simulation scenarios are designed to improve learner critical thinking to improve patient outcomes. A scenario can be set as a patient that requires intubation and mechanical ventilation. The result of the treatment provided by the learner will be shown on airway pressures, lung volume, arterial oxygen saturation, end-tidal CO2, and more. The outcome is not created by the operator but by the interaction between trainee and TestChest, in real-time and reproducibly. This allows the learner to reflect and learn on the positive and negative impact of all actions and interventions.

Neosim’s TestChest stands out as a highly accurate and versatile clinical simulator, making it the preferred choice for respiratory care training and for research and development of new ventilation devices. TestChest’s physiological modelling capabilities enable the representation of various pulmonary diseases and pathophysiology. The utilisation of real equipment and an actual multipara monitor, learners can gain a deep understanding of lung physiology and mechanical ventilation in a safe environment.

neosim’s TestChest offers healthcare learners a ground-breaking solution for mechanical ventilation training. With its autonomous functionality, realistic simulations, and the ability to replicate a wide range of clinical scenarios, TestChest provides a valuable tool for the enhancement of skills and knowledge of respiratory therapists and intensive care professionals.

TestChest LIFE

The TestChest LIFE control panel offers a user-friendly interface for operating the simulator. This allows operators to select pre-configured patients and adjust breathing activity. Changes in scenarios, such as transitioning from normal to airway obstruction to ARDS, can be easily made, which provides flexibility for training across various clinical scenarios. The complete case editor feature streamlines scenario creation by allowing goal setting and progression steps. Both paediatric and adult scenarios can be simulated using TestChest LIFE.

More About neosim

neosim is a Swiss company founded by clinical experts with a strong background in lung physiology and mechanical ventilation. neosim was founded on the development principles for healthcare simulators that have autonomous physiology which are based on published scientific data and are as close to reality as possible. The mission of neosim is to save lives from day one by using our autonomous simulators. For training and education of clinicians, especially respiratory therapists and intensive care professionals, neosim simulators create realistic breathing in health and disease. In contrast to other simulators, neosim’s simulators can be treated with intensive care therapy methods and equipment and respond autonomously like a real human patient. The results manifest themselves clinically and can be measured quantitatively with state-of-the-art monitoring in real-time.

neosim sought to create autonomous human lung simulators-real-time artificial intelligence for high-quality respiratory therapy training and education. The goal was to provide clinical training on mechanical ventilation for hospitals, simulation centers, and universities. Thus, the design support and testing of respiratory devices for manufacturers, test-houses, and biomedical engineering all kept in mind quality assurance for hospitals and manufacturers of respiratory care devices.

Ultimately, autonomous human lung simulators allow learners to accurately follow the actions of the ventilator and gain an understanding of the dynamics of closed-loop control as if there was a patient – but without harming a patient. Additionally, autonomous human lung simulators allow clinicians to expose the workings of their intensive care ventilators and respiratory support devices – and to improve the management of patients, according to neosim.
