Neopuff NICU嘅救仔工具

Neopuff 新認識嘅救仔工具😍
Neopuff同 Neopets 或俾Puff係完全無關係嘅!
一般做急救有ABC,開氣道,俾氧氣,做CPR,再advance啲嘅會俾inotrope,fluid Resuscitation等等.....
喺人手Bag嘅環節,有陣時一心急,揸大力咗個Ambu bag係好難避免😵喺初生嬰兒,特別係早產兒個肺特別delicate,俾你大力少少bag都好易爆肺pneumothorax💀👽🙈

咁點算??

😱Neopuff就大派用場!😎佢係一個positive pressure control device,你pre set 定俾幾多peak inspiratory pressure(PIP),同Peak end expiratory pressure(PEEP),咁你俾每一下氣都唔會起過你preset嘅pressure,大大減少爆肺🐔會 😍

講咁多廢話👿點駁個neopuff去個仔度架!!!!

(睇下圖)Neopuff 係一個pressure comprised device, 將個Oxygen or air source  經oxygen tubing連去gas inet(左下),再把patient circuit 駁去gas outlet,有個T -piece 連住patient circuit。 跟手揀定個fit size嘅mask就可以用喺個仔度!

😑😑😑作死你🐷未check機點可以俾仔用
簡單啲講,你得三個制搞,check機前駁test lung去t piece,Oxygen flow(8-10L/min for 初生嬰兒)
1)check Maximum pressure relieve:先將手指seal up T piece (如圖示)

扭PIP(右下) clockwise到最大,manometer應該show同preset嘅Max.Pressure 一樣(40 cm H2O),如果唔係,就打開個max Pressure 蓋(左下),調整到desired pressure.
2)check PIP : 繼續seal up t piece!!!!!扭個PIP 到你想要嘅level( recommend preterm<32 週出世 baby 👶👶20-25 cm H2O,30 cmH2O 俾full term baby👶👶) 
3)check PEEP: 放開手指,扭個T piece白蓋,喺manometer你會顯示到PEEP ( 5-8 cm H2O recommend) 


💂💂💂💂🐷🔫咩PIP,咩PEEP😑我雖然讀得書少,你唔好蝦我
💡PIP 即peak inspiratory pressure ,每下吸氣,可以俾到最大嘅pressure support,係正壓幫你打氣入肺
💡PEEP 即 peak end expiratory pressure,係呼氣後仍keep住打氣嘅壓力,prevent alveolar collapse😊呼氣後仍留喺alveolar 嘅air可以令下一次俾氣更容易🐷🐷🐷唔明?想像你第一下吹氣球🎈,要好大力,之後你再吹就好容易,因為氣球已打脹,同alveolar一樣,PEEP establish咗functional residual capacity,alveolar無咁易collapse,亦可improve gases exchange

加返個mask,CE technique (下圖示),jaw flush,good seal of mask睇1) manometer 即時show PEEP 2)聽到whistle sound喺T piece傳出
一下一下俾氣個仔,見到chest rise, heart rate升至100 bpm以上,improve oxygenation就為之effective bagging 


👿👿👿👿如果中途較高咗oxygen flow要reset PIP,PEEP,否則會有機會爆肺
💡Recap: Neopuff可以set定maximum PIP(減少爆肺)
Set PEEP(增加Functional Residue Capacity,oxygenation),
控制I:E ratio ( depends on the duration your thumb seal the cover)
