This document provides information about aspiration and nasogastric tube feeding. It begins with a multiple choice pre-test to assess knowledge. Aspiration is defined as breathing in foreign particles. Critically ill patients have the highest risk of aspiration during tube feeding due to factors like malposition or continuous feeding. Signs of aspiration include decreased oxygen saturation, cyanosis, coughing and wheezing. Nursing care focuses on oral care, proper positioning and monitoring gastric residuals to prevent aspiration pneumonia, a potential complication.

13. WHAT IS ASPIRATION?
Aspiration may refer to getting fluids (or small
solid particles) into the airways, such as
trachea or lungs.

14. SIGN OF ASPIRATION
Silent and Overt aspiration
Decreased oxygen saturation

15. • Cyanosis

16. RISK FOR ASPIRATION
RELATED TO NASOGASTRIC
TUBE FEEDING
Critically ill patient

17. WHAT INCREASE THE RISK OF
ASPIRATION?
-Wrong site
-Malposition
- Amount of feeding
- Continous feeding

18. SITE FOR AUSCULATION TO CONFIRM
THE PLACEMENT
• Left epigastrium(left hypochondriac region)

19. MEASUREMENT

20. NURSING CARE
• Assessment:

21. • Oral care
• Maintenance of the position

22. • Management of feeding intolerance

23. • Monitoring and management of GI tolerance

24. GASTRIC RESIDUAL VOLUME
• Gastric residual refers to the volume of fluid
remaining in the stomach at a point in time
during enteral nutrition feeding.
• INTERVAL: 4-8 hourly

25. HOW TO
PERFORM??

27. VISUAL CHARACTERISTICS OF
FEEDING TUBE ASPIRATES
• GASTRIC
 Grassy green with sediment
 Brown
Clear and colourless

28. • INTESTINAL
Bile stained (golden yellow or brownish)
• RESPIRATORY
Off white to tan sediments

29. COMPLICATION
• Aspiration pneumonia
• Pulmonary edema
• Death
