Esophageal Pressure in Anaesthetized Patients: Difficulties and Frequent Mistakes
Indirect measurement of pleural pressure, with the use of a balloon inserted in the esophagus, had been initially proposed by Luciani in 1878, nevertheless, this procedure only became popular from the work of Buytendijk in 1949 . Measurement of esophageal pressure (Pes) is an extremely useful method for the evaluation of respiratory mechanics (chest wall and lung). Several investigations allowed to estimate the values of elasticity and resistance of the lung and thoracic wall.
