C20/C in Neonatal Ventilation // The Hidden Number That Can Warn You !!

Have you noticed C20/C on a neonatal mechanical ventilator and wondered what this number actually means? C20/C compares the compliance during the final 20% of inspiration with the compliance of the entire breath. It can provide useful information about what is happening to the neonatal lung near the end of inspiration. In this practical NICU teaching video, I explain C20/C in a simple, clinically useful way. You will learn: What C20/C actually means How the ventilator calculates it The relationship between C20/C and the pressure-volume loop Why a C20/C below 1 may indicate decreasing compliance toward end-inspiration and possible lung overdistension Why a C20/C above 1 may suggest ongoing tidal recruitment What a value around 1 means How excessive PIP or tidal volume may affect C20/C How C20/C can help you recognize the “beaking” pattern of overdistension Why you should interpret C20/C together with tidal volume, pressures, lung mechanics, blood gases, and the baby's clinical condition Important limitations caused by ETT leak, respiratory timing, and patient–ventilator interaction C20/C should not be treated as an isolated target or magic cutoff. It is another piece of information that can help you understand neonatal lung mechanics and potentially recognize overdistension earlier. The key message: Don't just look at PIP and tidal volume — understand what happens to compliance at the end of the breath. #C20C #NeonatalVentilation #NICU #Neonatology #MechanicalVentilation #LungCompliance #PressureVolumeLoop #VentilatorGraphics #LungProtection #NICUTeaching
