Since appropriate tubes or their cuffs or cuffs can not guarantee a 100% tightness over time as a rule, these germ-contaminated fluids can enter the lungs following gravity and cause damage. serious complications. This means dramatic loss of quality of life for the affected patient - and, in some cases, Lifetime - enormous costs for the health sector.
