Closed Suction - Suction Technique and Guidance

This document provides guidance on closed suction technique for endotracheal tubes. It includes instructions on determining suction depth based on the endotracheal tube size, performing suctioning while supporting the endotracheal tube, and rinsing and cleaning the suction catheter after use. Tables are included showing the appropriate closed suction catheter and Y-adapter size based on the endotracheal tube size. Finally, potential issues like leaks or a catheter not suctioning are addressed in a troubleshooting guide.

Closed Suction – Suction Technique and Guidance

1. Looking towards the baby’s head, circle the colour in front of the calculated number
(ie: where ET tube is cut add 5cm)

To Determine Suction Depth: Observe in area directly from the lavage port connector
Number on ET tube nearest the endotracheal adapter tip _____cm
Add 5cm to the suction at ET tube tip + _____cm
Total _____cm

SUCTION TECHNIQUE

2. Add 10% to normal unit suction pressure


3. When suctioning SUPPORT & HOLD the ETT & Y-adapter
4. PASS the catheter down the ET tube 1-2cm a time until you see the appropriate
colour (as calculated above) in the OBSERVATION AREA
5. Depress the thumb valve and count for 1 second to transfer the suction to the end of
the suction catheter - if your baby will tolerate this
6. Slowly pull back the suction catheter keeping the SUCTION ON
7. Pull back until you see the BLACK MARK in the RINSE CHAMBER

To Rinse / Clean the Suction Catheter


1. Attach syringe to the saline flush port
2. FIRST DEPRESS the thumb valve to TURN ON SUCTION and the slowly introduce the
saline ensuring your suction is on at all times. This should be done after each
suctioning procedure
3. When you have finished, disconnect the syringe and replace flush port cap

To Lavage
1. Attach syringe to saline flush port
2. Gently HOLD the Y-adapter & ET tube as VERTICAL as possible
3. INTRODUCE the SALINE in 0.1 - 0.2ml increments
4. REMEMBER: When 1st setting up you will need to prime the flush port with 0.5ml
Closed Suction Catheter Size Selection

Size (fr) ET tube (mm) Closed Suction Open Suction


5 2.5 Grey Grey
6 3.0 Green Green
7 3.5 Yellow Purple
8 4.0 Blue Blue
10 5.0 Black Black

Y-Adapter Size Selection


Each ‘Y’ Adapter has a number printed on it.Match the number on the ‘Y’ to the size of the
ET tube or half a size smaller.
Eg:
ET Tube Size of ‘Y’
2.5 mm 2.5 / 2.0
3.0mm 3.0 / 2.5
3.5mm 3.5 / 3.0
4.0mm 4.0/ 3.5

Trouble Shooting Guide

Ventilator displays leak Check all connections are tightly in place and secure

Catheter bag has blown up Remove the catheter from the ‘Y’adpter and
squeeze air out of the catheter bag and replace
immediately

Catheter is not suctioning Pull catheter out of airway until black marker is in
the rinse chamber.
With the suction on, flush the catheter with saline
until cleared.
Secreation plugs on the tip can be removed by
disconnecting the catheter and wiping with a sterile
wipe.
Recconect.
