The following patients were recorded from a patient receiving mechanical ventilation: corrected tidal volume = 520 mL, peak inspiratory pressure = 42 cm H₂O, plateau pressure = 29 cm H₂O, PEEP = 10 cm H₂O. What is the calculated static compliance, and is it acceptable based on the criteria for weaning?

Question

Static compliance is calculated as tidal volume divided by (plateau pressure - PEEP). Here, it is 520 mL / (29 - 10) cm H₂O = 27 mL/cm H₂O. This value is generally considered low and unacceptable for weaning.
