Trouble shooting : Find the etiology
Caveat 1:真的不行, 改接BVM試試
Caveat 2:呼吸器病人如果突然血壓血氧一起掉了, high pressure alarm
要趕快排除 Tension pneumothorax

Low pressure alarm : Air leak
Flow time curve 沒有歸零
病人端 / 呼吸器端 管路檢查哪裡沒接好
Bronchoesophageal fistula
Bronchoesophageal fistula
High pressure alarm :
PIP and Plautea pressure relationship
Inspiratory hold -> Plautea pressure
Inspiratory hold -> Plautea pressure
Peak Inspiratory Pressure (PIP) overcome resistive forces of the endotracheal tube and upper proximal airways
Usually the difference between PIP and PPlat is <5 cmH20 (PIP always > PPlat)
Usually the difference between PIP and PPlat is <5 cmH20 (PIP always > PPlat)
High airway resistence : 抽痰排水, Bronchospasm
High plautea pressure : Low lung compliance (肺泡問題)
