ERVA Transport Ventilator For Ambulance & Hospital


ERVA is an Emergency Respiratory Ventilation Apparatus. A Non Invasive (NIV) portable ventilation device to suit emergency response as well as personal care.

ERVA is an Automated Bag Valve Mask (BVM) system which provides mechanical ventilation through a highly controlled fashion. A plug and play device through minimal training, any healthcare personal can operate it.

ERVA Best Transport Ventilator

By simplifying conventional ICU Ventilators with an intuitive design we can easily set it up with 3 major parameters which are tidal volume, inspiration to expiration (I:E) ratio and respiratory rate. ERVA offers up to 8 hours of battery life and has built in audio-visual alarms keeping safety first. With compact form factor and user friendly interface ERVA bridges the gap between a manual Ambu bag and an ICU ventilators when they aren’t easily available. This device offers a Boost to Viable and Cost-Effective emergency treatments.

The robust design delivers consistent airflow which makes it applicable to be used in tough emergency environments to treat Covid-19 or other respiratory related emergencies. It can be used with or without oxygen in-line as per the patient requirement.
