Closed Suction System
To ventilator
To T-Tube/ETT
Traditional method:
Disconnection from
closed suction system at TTube/ETT junction
To ventilator
To T-Tube/ETT
Original use of mucus extractor
(with suction catheter)
To T-Tube/ETT
To Silicon tube/ Suction
Original use of mucus extractor
(without suction catheter)
To Suction Catheter
without stopper
To Yconnector +
Silicon tube/
Suction
To T-Tube/ETT
Disadvantages of
disconnection
1. Contamination of environment and
increase risk of cross infection
2. Temporary discontinuation from
ventilator support and oxygen
supply
3. Less convenient approach for
implementation of aseptic
technique
Principle: Keep using of
original closed suction system
A. Mucus extractor with suction
catheter
B. Mucus extractor without suction
catheter
A. Modified Use of Mucus extractor
(with suction catheter)

Bypass of Sputum
To Silicon tube/ Suction
‘Bypass’ of Sputum
To Suction Catheter of
Closed Suction System
Practical tips to
Minimize the Effect of
‘Sputum Bypass’
Use traditional method (disconnection
from closed suction system at TTube/ETT junction) for the following
conditions:
1. If the above suggestion failed
2. Unable to collect sputum from closed
suction catheter (e.g. very thick sputum or
patient has a long upper airway and distal
sputum)
3. ? New closed suction catheter
( Colonisation Vs Costing )
