Summary

Introduction: new methods of evaluation of respiratory function, such as electrical impedance tomography (EIT) and optoelectronic plethysmography (OEP), have been used to measure regional pulmonary ventilation and the variation of tricompartmental volumes of the thoracic cavity, respectively. Analysis of these instruments during maximal respiratory maneuvers with monitoring of esophageal pressure may probably provide additional information on the physiological behavior of the cardiorespiratory system during EIT and OEP maneuvers. Objectives: To describe the physiological behavior of maximal respiratory maneuvers through the electrical impedance tomography and optoelectronic plethysmography in healthy men.

METHODS: This is a cross-sectional study involving 10 healthy male volunteers. The development of the method will take place in 3 stages. The first step corresponds to the characterization of the inspiratory and expiratory curves in the respiratory cycle generated by the impedance variation (ΔZ), the mobility of the chest wall and the pulmonary volume curve during maximal respiratory maneuvers. 2nd stage: verification of the correlation between the variables Step 3: Estimate the dislocated blood volume of the lung through previous analyzes.
