Automatic Tube Compensation During Weaning From Mechanical Ventilation

Effects of Endotracheal Tubes in Spontaneously Breathing Patients Respiratory Workload Imposed by the Endotracheal Tube In healthy persons, respiration occurs with little effort. Respiratory work is required, however, to overcome the natural forces that oppose inhalation, such as the elasticity and resistance of the respiratory system, which is termed respiratory load. The ability to overcome the respiratory load is determined by respiratory muscle capability, especially diaphragm capability. Respiratory muscle capability is impaired by prolonged mechanical ventilation and conditions such as sepsis and chronic obstructive pulmonary disease. In addition, drugs such as neuromuscular blocking agents and corticosteroids may also impair Takeshi Unoki, RN, PhD Akimichi Serita, RN, RCET Mary Jo Grap, RN, PhD
