Product Description

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.
