允许气管内吸引而不与机械通气断开连接的呼吸机适配器可以克服几个理论上导致新生儿气管内吸引相关的缺氧和心动过缓的因素。这种适配器允许部分通气气管内吸（PVETS），而不是传统的非通气气管内吸。为了验证采用气管内吸气管插管（PVETS）的临床价值，我们比较了11例呼吸窘迫综合征早产儿32次PVETS与非通气气管内吸气管时经皮氧分压和心率的变化。部分通气气管内吸痰与低氧事件的发生率和严重程度显著降低有关。然而，部分通气气管内吸引不影响心动过缓事件的发生率；PVETS对降低心动过缓的严重程度有很小但有统计学意义的影响。心动过缓和缺氧事件之间没有明确的关系。
Ventilator adapters that permit endotracheal suction without disconnection from mechanical ventilation may overcome several of the theoretical contributors to the hypoxia and bradycardia associated with neonatal endotracheal suction. Such an adapter allows for partially ventilated endotracheal suction (PVETS) as opposed to traditional, non-ventilated endotracheal suction. To test the clinical value of PVETS using an endhole adapter, changes in transcutaneous partial pressure of oxygen and heart rate were compared during paired PVETS and nonventilated endotracheal suction events on 32 occasions in 11 premature neonates with respiratory distress syndrome. Partially ventilated endotracheal suction was associated with a significant decrease in the incidence and severity of hypoxic events. Partially ventilated endotracheal suction, however, did not affect the incidence of bradycardic events; PVETS had a small but statistically significant effect on reducing the severity of bradycardia. No clear relationship between bradycardic and hypoxic events was evident.
