Can you calculate the total respiratory, lung, and chest wall respiratory mechanics?

Abstract

Figure: Waveforms for a patient undergoing mechanical ventilation with volume controlled mode. Tidal Volume of 500 ml, PEEP 15, Constant inspiratory flow of 45 l/min A: Airway pressure in cmH2O, B: Esophageal pressure in cmH2O, C: Trans-pulmonary pressure in cmH2O, D: Flow in l/min, E: Tidal volume in ml Red dashed horizontal line: values at end of expiratory occlusion maneuver, White solid horizontal line: values at end of inspiratory occlusion maneuver, Green dashed horizontal line: values during peak inspiratory pressure.

Alveolar mechanics: A new concept in respiratory monitoring

“…PA: alveolar pressure, PAO: airway pressure, PBS: body surface (atmospheric) pressure, PPL: pleural pressure.The common mechanics that can be calculated during static (passive) and dynamic (active) conditions are the Compliance, Elastance (1/Compliance), Resistance, and total PEEP. Those can further be divided into: Total respiratory, Lung, Chest wall according to the calculations below13…”
