Improving bedside ventilation monitoring

A portable ultrasound scanner to monitor the condition of patients in intensive care and make work easier for caregivers

Professors Jean-Jacques Rouby and Jean-Michel Constantin from the Department of Anaesthesia and Resuscitation of the Pitié-Salpêtrière Hospital are keen to make monitoring of the respiratory status of patients severely affected by SARS- CoV-2 easier. They have launched a clinical trial to compare the use of a portable ultrasound scanner at the patient's bedside with the conventional protocol.

Use of a portable ultrasound scanner

Faced with an influx of patients, the Pitié-Salpêtrière Hospital has opened up new intensive care beds for SARS-CoV-2 patients. These rooms are cramped and not very compatible with the use of traditional ultrasound scanners, which are bulky and difficult to clean, or with the practice of chest X-rays at the patient's bedside. Moreover, transporting patients is a major task and brings with it a high risk of contamination. Using a portable ultrasound scanner could be the solution for improving bedside ventilation monitoring and making the work of caregivers easier.

Professors Jean-Jacques Rouby and Jean-Michel Constantin are conducting a clinical study on 160 patients to demonstrate that using portable ultrasound scanners shortens the ventilation period of severely affected patients compared to a standard clinical assessment by chest X-ray and conventional chest ultrasound. 

Use of this kind of ultrasound scanner would be a first in the intensive care environment in France and could be rolled out elsewhere following the study.

How the Air Liquide Foundation is participating

The Air Liquide Foundation is enabling the acquisition of 5 ultra-portable scanners to monitor patient respiratory status and make the work of staff easier.
