Atelectasis is a common, noninfectious complication in individuals receiving mechanical ventilation. The occurrence of lung collapse leads to changes in ventilatory mechanics, worsens lung injuries, alters the ventilation/perfusion ratio and causes hypoxemia. Lung collapse is also associated with a greater risk of respiratory infections and readmission to or a longer stay in the intensive care unit [In this context, lung expansion strategies are adopted to reverse or prevent atelectasis and avoid these complications; these strategies promote an increase in lung volumes by increasing the transpulmonary pressure gradient, which can be caused by an increase in alveolar pressure or a decrease in pleural pressure [The most common methods for promoting lung expansion utilize mechanical ventilation with positive pressure to increase alveolar pressure, such as alveolar recruitment [Techniques that utilize an increase in positive pressure present few serious adverse events. Transient hypotension and desaturation are the most common adverse events, but they have been observed to be self-limited and do not lead to severe short-term sequelae. Serious adverse events such as barotrauma and arrhythmias were infrequent [Other techniques for lung expansion induce a reduction in pleural pressure. Passive manual manoeuvres are among these strategies and include compression-decompression [However, despite being widely used in clinical practice [
