Esophageal Manometry

Abstract: The estimation of pleural pressure with esophageal manometry has been used for decades, and it has been a fertile area of physiology research in healthy subject as well as during mechanical ventilation in patients with lung injury. However, its scarce adoption in clinical practice takes its roots from the (false) ideas that it requires expertise with years of training, that the values obtained are not reliable due to technical challenges or discrepant methods of calculation, and that measurement of esophageal … Show more

“…This technology estimates transpulmonary pressure (the pressure gradient across alveoli) by accounting for intrapleural pressures, in contrast to traditional direct airway pressure measurements. 36 Measuring the end-inspiratory and end-expiratory pressures in both the airway and the esophagus generates a transpulmonary pressure profile that is useful in obesity, where chest wall compliance can become so poor that the effective PEEP can remain negative even with high PEEP settings. In the 2019 EPVent-2 randomized control trial, there was no difference in mortality between ventilation management using esophageal manometry and traditional PEEP/FiO2 titration.…”

“…La presión de la vía aérea es muchas veces asumida como el reflejo de las fuerzas aplicadas en el pulmón y es utilizada para monitorizar la ventilación mecánica en la práctica clínica. Esta asunción es errónea porque la presión de la vía aérea es una medida de las propiedades elásticas y resistivas del sistema respiratorio en su totalidad, cuyo comportamiento depende de sus características propias y de la interacción de sus componentes: el pulmón y la caja torácica [12], [13]. Consecuentemente, la presión de la vía aérea, actúa en estas dos estructuras elásticas ubicadas en serie [4].…”

“…Pero esto no significa que refleje la presión de distensión del pulmón aisladamente (medido efectivamente por la presión transpulmonar). La presión meseta, en cambio, representa la presión de retroceso elástico del sistema respiratorio en su conjunto que comprende tanto al pulmón como a la caja torácica [12]. En casos donde la elastan-cia de la caja torácica sea normal, el valor de la presión meseta se acercará al valor de la presión transpulmonar.…”

“…Apart from ultrasonography, techniques used to diagnose DD include chest radiography, fluoroscopy, electromyography, measurements of esophageal pressure and its derived indices (such as transdiaphragmatic pressure [P DI ]) and phrenic nerve stimulation (Table 1). 6,11,15,[19][20][21][22][23][24][25] Techniques used in adults, such as the measurement of maximal inspiratory or expiratory pressure, may not be viable in infants and young children given their inability to cooperate.…”
