By AYALEW K. 3

3. ✓ used for diagnostic, therapeutic, preventative, and feeding
purposes.
✓ It provide for analysis purpose of GI contents.
✓ To remove stomach contents after suspected poisoning
✓ To wash the stomach after suspected poisoning

Purpose/Indication:
By AYALEW K. 4

4. Before inserting the tube
1
• Inform to the patient about the
procedure
2
• Position the patient (Semi flower)
3
• Measure the tube.
By AYALEW K. 5

5. ✓ By placing tip of the tube on the patient's nose and
touches the tip of the xiphoid process.
By AYALEW K. 6

6. After inserted check the tube in stomach or not
1. Auscultation
✓instilling air into the feeding tube with a
syringe and placed a stethoscope over the
stomach to listen for rushing air.
✓Misinterpretation of auscultation of air
insufflation is known as pseudo-confirmatory
gurgling.
By AYALEW K. 7

7. 2. Bubbling
✓Observing bubbles when the end of the feeding
tube is placed under water.
✓Also, the absence of bubbles does not rule out
respiratory placement if the tube’s ports are
occluded by the respiratory mucosa.
By AYALEW K. 8

8. 3. Aspirate Appearance
✓ assessing the appearance of aspirate from the tube.
Ordinarily,
– Small bowel aspirates are golden yellow or greenish brown
– Gastric aspirates are often grassy green, off-white, or tan.
– Respiratory secretions can be white, yellow, straw-colored
✓ Because both respiratory and gastrointestinal
aspirates may be similar in color, they may be easily
misinterpreted.
By AYALEW K. 9

9. 4. PH Testing
✓Determining the pH of aspirated gastric fluid
usually acidic, with a pH less than or equal to
5.5.
✓Respiratory secretions are almost always
alkaline, with a pH greater than or equal to 6.
By AYALEW K. 10

14. ✓Explain the procedure to the client
✓Position the client in a sitting or high fowlers
position. If comatose-semi fowlers.
✓Determine the length of tube to be inserted.
✓Measure distance from the tip of the nose to the
earlobe and to the xyphoid process of the sternum.
✓Prepare NG tube for insertion.

17. Implementation
1- Wash Hands
2- Put on clean gloves
3- Lubricate the tube
4- Hand the client a glass of water
5- Gently insert tube through nostril to back of throat
(posterior naso pharynx).
6- Emphasize the need to mouth breathe and swallow during the
procedure.
7- Swallowing facilitates the passage of the tube through the
oropharynx.
8- Advance tube each time client swallows until desired length has
been reached.
9- Do not force tube. If resistance is met or client starts to cough,
choke or become cyanotic stop advancing the tube and pull back.
