Advances in ventilator technology and recent findings in pathophysiological mechanisms have resulted in a remarkable decrease in classical volume controlled and pressure controlled ventilation modes as treatment for severe acute respiratory insufficiency. New modes of ventilatory support enabling and encouraging patients' spontaneous breathing, such as Biphasic Positive Airway Pressure (BIPAP) and Airway Pressure Release Ventilation (APRV), make it possible to adapt ventilatory support better and more easily to suit patients' needs than conventional modes of controlled ventilation. Preservation and support of patients' spontaneous breathing improves pulmonary gas exchange and reduces stress imposed by mechanical ventilation. The 'invasiveness' of mechanical ventilation is reduced and patients' comfort is less disturbed. Through this, the need for sedation and analgesia is considerably reduced and this may minimize systemic side-effects and complications from analgo-sedation and mechanical ventilation. The drugs should be administered in an adequate, individually adapted manner. Routinely-ordered and fixed combinations of drugs administered continuously are not adequate adequate as they further carry the risk of overdosing a different single drug with the corresponding side-effects (depression of respiratory drive, gut motility, etc.).
呼吸机技术的进步以及病理生理机制方面的最新研究结果,已导致用于治疗严重急性呼吸功能不全的传统容量控制和压力控制通气模式显著减少。新的通气支持模式,如双相气道正压通气(BIPAP)和气道压力释放通气(APRV),能够且鼓励患者自主呼吸,与传统的控制通气模式相比,使通气支持能更好、更轻松地适应患者需求。保留并支持患者的自主呼吸可改善肺气体交换,并减轻机械通气带来的压力。机械通气的“侵入性”降低,患者舒适度受干扰程度减轻。由此,镇静和镇痛的需求大幅减少,这可能会将镇痛镇静和机械通气的全身副作用及并发症降至最低。药物应以适当、个体化调整的方式给药。常规连续使用的固定药物组合并不合适,因为它们进一步存在使不同单一药物过量并产生相应副作用(呼吸驱动抑制、肠道蠕动抑制等)的风险。
