What IDDSI Level Is Nectar Thick Liquid?

6 min read

According to the International Dysphagia Diet Standardisation Initiative (IDDSI), the term 'nectar thick liquid' corresponds to Level 2, also known as 'Mildly Thick'. This standardized terminology replaces older, more ambiguous descriptions to ensure consistency and improve safety for people with swallowing difficulties (dysphagia).

Quick Summary

The IDDSI framework standardizes liquid thickness, with nectar thick liquid corresponding to IDDSI Level 2, or Mildly Thick. This level is for individuals with dysphagia who require a slower-flowing liquid that can still be sipped from a cup. The consistency is easily pourable but flows more slowly than thin liquids.

Key Points

  • IDDSI Level 2: Mildly Thick: The term 'nectar thick liquid' is standardized as IDDSI Level 2, or Mildly Thick.

  • Standardized for Safety: The IDDSI framework replaced subjective terms to ensure consistent fluid thickness and enhance patient safety for individuals with dysphagia.

  • The IDDSI Flow Test: An objective test using a 10 mL syringe confirms Level 2 liquids by checking that 4-8 mL remains after 10 seconds of flow.

  • Characteristics of Mildly Thick: The liquid is easily pourable but flows slower than thin drinks, and it requires some effort to be sipped through a straw.

  • Consistent Preparation is Key: The viscosity of a liquid can be affected by factors like temperature, so it is crucial to follow thickener instructions carefully and test under intended serving conditions.

Understanding the IDDSI Framework

Before exploring what IDDSI level is nectar thick liquid, it's crucial to understand the International Dysphagia Diet Standardisation Initiative (IDDSI) framework itself. Created by a volunteer group of international experts, IDDSI provides a universal framework of standardized terminology for describing texture-modified foods and thickened liquids for people with dysphagia. This eliminates the confusion caused by different terminologies used across facilities and countries, ultimately enhancing patient safety.

The IDDSI framework uses a continuum of eight levels, numbered 0 to 7. Levels 0 to 4 categorize drinks, while levels 3 to 7 categorize foods. The consistency and flow characteristics for each level are clearly defined and can be objectively tested using simple, practical methods, such as the IDDSI Flow Test for liquids. This testing ensures that liquids consistently meet the prescribed thickness, an essential step in preventing aspiration and promoting safe swallowing.

What Makes a Liquid 'Nectar Thick'?

Historically, 'nectar thick' was a subjective term, often causing variation in liquid consistency depending on preparation and interpretation. Under the modern, standardized IDDSI system, nectar thick liquid is formally known as Level 2: Mildly Thick. This level is thicker than water but thinner than a honey-like consistency. It is defined by its specific flow properties, which can be reliably confirmed using the IDDSI Flow Test.

Key characteristics of a Level 2: Mildly Thick liquid include:

  • Easily pourable but flows more slowly than thin liquids.
  • Can be sipped from a cup.
  • Requires some effort to drink through a standard straw.
  • Will leave a mild coating on a spoon or fork when dripped.

For individuals with dysphagia, these properties allow for more controlled and safer swallowing. The slower flow rate gives the person more time to control the liquid in their mouth and prepare for the swallow, reducing the risk of aspiration.

The IDDSI Flow Test for Level 2 (Mildly Thick)

The IDDSI Flow Test provides a simple, objective method for testing liquid thickness. It requires a 10 mL syringe with a standard 'slip tip' opening.

Testing Procedure:

  1. Cover the nozzle of a 10 mL syringe with your finger.
  2. Fill the syringe to the 10 mL line with the liquid you are testing.
  3. Remove your finger and, simultaneously, start a timer for 10 seconds.
  4. After 10 seconds, cover the nozzle again and measure the amount of liquid remaining in the syringe.

For a liquid to be classified as Level 2 (Mildly Thick), the test requires that between 4 and 8 mL of liquid remains in the syringe after the 10-second flow period. This precise, objective measure is a significant improvement over the subjective 'nectar-like' descriptions of the past.

Comparing Nectar Thick (IDDSI Level 2) with Other Levels

To fully appreciate what IDDSI level is nectar thick liquid, it helps to compare it with the adjacent levels in the IDDSI framework. This demonstrates the critical differences in viscosity and flow that affect patient safety.

Feature IDDSI Level 1 (Slightly Thick) IDDSI Level 2 (Mildly Thick) IDDSI Level 3 (Moderately Thick)
Old Term Lightly thick Nectar thick Honey thick
Flow Test Result (10s) 1-4 mL left in syringe 4-8 mL left in syringe >8 mL left in syringe
Pourability Flows faster than Level 2, but slower than water Easily pourable, flows slowly off a spoon Flows very slowly, can be poured
Sipping Can be easily sucked through a straw Requires some effort to sip through a straw Cannot be easily sucked through a straw
Typical Examples Some fruit nectars, thick milk-based drinks Thick milkshakes, creamy soup Thick yogurt, thick smoothies

Preparation and Considerations for IDDSI Level 2

Preparing a liquid to the correct IDDSI Level 2 consistency is vital for patient safety. It is important to note that a liquid's thickness can be affected by several factors, including temperature, the brand of thickener, and the amount of thickener added. Always follow manufacturer instructions carefully, and re-test the liquid if you notice a change in temperature or consistency.

While thickeners are commonly used to achieve the desired consistency, some liquids are naturally or can be modified to be mildly thick. For example, some pureed soups or thick milkshakes may fall into this category. However, using the IDDSI Flow Test is the most reliable way to confirm the exact consistency.

Conclusion

The question, "what IDDSI level is nectar thick liquid," is now clearly answered by the standardized IDDSI framework. Formerly known as nectar thick, this consistency is now formally defined as IDDSI Level 2: Mildly Thick. This modern terminology, combined with objective testing methods, eliminates the ambiguity of older descriptions and provides a safer standard of care for individuals with dysphagia.
