Laerdal Servi Ventilator
The Laerdal Servi Ventilator is an emergency invasive ventilator designed and implemented in response to the COVID-19 pandemic.
Developed in 2020 in response to the needs from the global COVID-19 pandemic, the Laerdal Servi Ventilator is an emergency invasive ventilator designed not to replace existing ventilators in over-capacity hospitals, but to offer a supplemental technology in emergency situations. As such, the design features settings for sedated patients with respiratory failure, intended to be used over a relatively short period of time on the patient.
This product was selected for inclusion in WHO’s 2021 Compendium of Innovative Health Technologies for Low‐Resource Settings.
The device is designed for emergency use in hospitals in Norway, the United Kingdom, and other European nations.
This product was implemented by the following organizations: the Norwegian Defense Research Establishment, Edge Health Technologies AS, Laerdal Medical AS, and Servi AS.
Emergency invasive ventilators available in Europe
Goal 3: Good health and well-being
Medical professionals in over-capacity hospitals with emergency situations in Europe.
The emergency ventilators are purchased by European governments to then distribute to hospitals in need.
