What is Validation of a New Respiratory Inductive Plethysmograph about?

**Background:** The respiratory inductive plethysmograph (RIP) can be used to monitor changes in end‐expiratory lung volume (ΔEELV), and thus, used in intensive care when evaluating positive end‐expiratory pressure (PEEP)‐induced changes in lung volumes in order to optimise the ventilator settings. We validated the newest model of RIP (Respitrace Plus^TM^), both under laboratory and clinical conditions, and made a comparison with a previously validated RIP (Respigraph^TM^) in the measurement of tidal volume (V~T~), long‐term EELV and PEEP‐induced acute ΔEELV. **Methods:** The __in vitro__ validation was performed using a lung model and the __in vivo__ evaluation in five spontaneously breathing normal subjects, four patients with acute lung injury (ALI) and eight anaesthetised patients. **Results:** The difference in V~T~ values during PEEP manipulations between pneumotachometer (PNT) and RIP in spontaneously breathing volunteers and mechanically ventilated ALI patients was 0.1±0.9% (mean±SEM) and −5.2±0.6, respectively (effect of device NS). In anaesthetised patients, the difference between the new RIP and spirometer in the measurement of PEEP‐induced acute ΔEELV was −2.6±1.5% (PEE
