Thickened fluids
Thickened fluids and thickened drinks are often used for people with dysphagia, a disorder of swallowing function. The thicker consistency makes it less likely that an individual with will aspirate while they are drinking. Individuals with difficulty swallowing may find liquids cause coughing, spluttering or even choking and thickening drinks enables them to swallow safely. Patients are often ordered onto thickened liquids after being extubated. Liquid thickness may be measured by two methods, with a viscometer or by line spread test.
There are several levels of consistency/viscosity.
Thin liquids: Unthickened, such as water or juice. Common thin liquids include coffee, tea, clear broth, clear juice, skim milk, 2% milk, and whole milk.
Nectar thickened: Approximately as thick as a milkshake. Should pour in a continuous stream without "breaking" into drops. Common "natural" nectar thick liquids include nectar, tomato juice, and buttermilk.
Honey thickened: Sticks to the sides of a cup like honey. Pours very slowly. Liquids include honey and cream soups.
