Brief Summary
Recently, ultrasound artifacts mimicking lung sliding have been described in absence of the visceral pleura, in a group of patients who underwent pneumonectomy. In these patients, lung sliding was clearly absent during mechanical ventilation in the operated hemithorax. During spontaneous breathing, although of lower intensity compared to the unoperated hemithorax, some artifacts mimicking lung sliding and seashore sign were found during each deep spontaneous breath. These findings have led to the hypothesis that these artifacts may be due to the contraction of the intercostal muscles. The objective of the present study is to reproduce such artifacts during contraction of the inspiratory and expiratory muscles with closed glottis (Valsalva and Muller maneuvers): in this condition each subject is not ventilating and the two pleural layers are not sliding one over each other.

Outcome Measures
Primary Outcomes (1)
lung ultrasound artifacts during contraction of the inspiratory and expiratory muscles with closed glottis (Valsalva and Muller maneuvers).
16 days
Study Arms (1)
Ultrasound findings
EXPERIMENTALThoracic ultrasound examinations in the following conditions: 1. Apnea; 2. Spontaneous regular breathing; 3. Valsalva maneuver, during which each subject will be asked for performing three forced expirations with closed glottis after one forced inspiration; 4. Muller maneuver, during which each subject will be asked for performing three forced inspirations after one forced expiration; 5. Hyperventilation.
