The importance of an inspiratory hold and a prolonged inspiratory ramp for the detection of bronchopleural leaks in an <i>ex vivo</i> model.

ABSTRACT:

Background

Before the chest is closed, the airtightness of the remaining lung is regularly checked after anatomical and non-anatomical lung resections. The thoracic cavity is filled with sterile water and the lungs are reventilated with a peak inspiratory pressure (Pinsp) of +25 mbar at a positive end-expiratory pressure (PEEP) of +5 mbar. The surgeon inspects the surface of the lung, especially the sutures, for leaks. In the event of a leak, air escapes in varying amounts; this can range from individual air bubbles to a massive leak of air. At this stage, the surgeon is still able to take corrective measures. Methods range from suturing to covering the leak site with a collagen fleece. An overlooked leak usually has serious consequences. Despite the leak test described above, air
