mechanical ventilation‚ associated or not with haemodynamic instability‚ and its application fields are widening to refractory sepsis and also to elective thoracic procedures. ECMO is replacing conventional cardio-pulmonary by-pass (CPB) even during lung transplantation due to its potential advantages: the absence of full-anticoagulation and the possibility of maintaining the extra-corporeal support even in the post-operative period. An emergent role of ECMO is the intraoperative support during complex

Inhalant anaesthesia in dorsal recumbency can result in hypoventilation and in the development of intrapulmonary shunts (Oura et al. 2012). The respiratory dysfunction is associated with formation of atelectasis in dependent lung areas‚ which can impair pulmonary compliance‚ gas exchange and oxygenation (Staffieri et al. 2007; De Monte et al. 2013). Such alterations may be prevented by using mechanical ventilation‚ which can be adjusted in terms of fraction of inspired oxygen (FiO2)‚ positive end-expiratory

organs are the Lungs‚ Trachea‚ Bronchi‚ and the Diaphragm. The lungs are considered the main organ of the system. It takes in the oxygen and releases the carbon dioxide. How this happens is the red blood cells take oxygen to the body and take the carbon dioxide to the lungs‚ and this allows us to breath. The trachea cleans the air that we breathe in‚ it works as a filter. This filter flows into the bronchi‚ which is the next organ. The bronchi carries the air into the lungs‚ this is the

fact‚ without it‚ the body would never recover from injury. In COPD‚ repeated exposure to airway irritants perpetuates an ongoing inflammatory response that never seems to shut itself off. Over time‚ this process causes structural and physiological lung changes that get progressively worse. As inflammation continues‚ the airways constrict‚ becoming excessively narrow and swollen. This leads to excess mucus production and poorly functioning cilia‚ a combination that makes airway clearance especially

Tension pneumothorax develops occasionally and is a medical emergency. Unless reversed
