Abstract
The measurement of functional residual capacity (FRC) may help optimizing lung protective ventilation in patients with acute respiratory distress syndrome, but it is not routinely per- formed in clinical practice yet (1). Oxygen (O2) washin/washout is a simple technique available at bedside to estimate FRC (2). However, it relies on sidestream gas analyzers, which lack of appropriate syn- chronous measurements of ow and gas concentration requiring complex calculations to correct for time, gas viscosity and pres- sure (3–5). Recently, a mainstream oxygen sensor prototype cou- pled in series with a uximeter and a very fast time response and a good precision has been developed (named Italian Fast OXygen sensor—IFOx®).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
