which guideline is recommended for determining suction catheter depth when suctioning an endotracheal tube?
Fudgin [204]

The recommended guideline for determining suction catheter depth when suctioning an endotracheal tube is;

<u><em>By using a suction catheter with centimeter increments on it.</em></u>

<u><em>Insert the suction catheter into the endotracheal tube until the centimeter markings on both the endotracheal tube and catheter align</em></u>

<u><em>Insert the suction catheter no further than an additional 1 cm.</em></u>

<u><em /></u>

       From documented guidelines to determine suction catheter depth, they are;

1) Get a suction catheter with centimeter increments on it.

2) Then you will Insert the suction catheter into the endotracheal tube till the centimeter markings located on both the endotracheal tube and catheter align

3) Next is to insert the suction catheter not more than an extra 1 cm.

4) The length of the endotracheal tube should be combined with any other adapter you are using after which you add an additional 1 cm.

5) Get a spare <em>endotracheal tube</em> that has same size as that being used for the patient.

6) Insert the suction catheter to the end of this tube and take note of the length at which the catheter got to the end of the tube.

7) If you are dealing with a closed system, then all you need to do is to combine the endotracheal tube length and length of additional adapters you are using and add an extra 1 cm.
