Intervention

Other:
• lemonade ice cubes
Mixing 1 part lemon juice and 6 parts boiling water, make 10ml lemonade ice cubes. The experimental group was given a 10ml lemonade ice cube. The ice cubes were weighed first and then given. The subjects were required to hold the lemonade ice cube in their mouths without breaking them, and not to swallow saliva. 45 seconds after the intervention is given, the nurse will use tweezers to take out the ice cube from the subject's mouth and weigh it , and then place the dry cotton swab at the opening of the sublingual gland in the oral cavity, take it out after 1 minute, and collect saliva, the recorded saliva volume = the collected saliva volume minus (10 ml ice cube weight minus the remaining ice cube weight); The experimental group was given a brand new 10ml lemonade ice cube. At 90 seconds, 135 seconds and 180 seconds, the above saliva collection method was repeated for a total of 5 times of saliva collection.
• water ice cubes
make 10ml water ice cubes. The control group was given a 10ml water ice cube. The ice cubes were weighed first and then given. The subjects were required to hold the water ice cube in their mouths without breaking them, and not to swallow saliva. 45 seconds after the intervention is given, the nurse will use tweezers to take out the ice cube from the subject's mouth and weigh it , and then place the dry cotton swab at the opening of the sublingual gland in the oral cavity, take it out after 1 minute, and collect saliva, the recorded saliva volume = the collected saliva volume minus (10 ml ice cube weight minus the remaining ice cube weight); The control group was given a brand new 10ml water ice cube. At 90 seconds, 135 seconds and 180 seconds, the above saliva collection method was repeated for a total of 5 times of saliva collection.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Thirst intensity measured using an Visual Analogue Scale (VAS)	The VAS is a 100 mm line with anchor statements on the left (score :0 mm , no thirst) and on the right (score: 100 mm, extreme thirst).; Change= (180 second score - baseline score)	baseline and 180 second
Primary	Thirst distress measured using a Thirst Distress Scale-Heart Failure Taiwan version(TDS-HF)	The TDS-HF consists of 8 statements about how the patient experiences his/her thirst during the last 2-3 days (a total of 8 items). The 8 items are rated on a 5-point Likert scale. Patients are instructed to read each statement carefully and choose one of 5 possible answers for each statement that best describes the patients experience of thirst between strongly disagree (on the left side, number 1) and strongly agree (on the right side, number 5).; Change= (180 second score - baseline score)	baseline and 180 second
Primary	Change from Baseline in Measure Saliva Amount at 45 seconds.	Uses a dry cotton stick to place the sublingual gland opening in the subject's oral cavity for 1 minute, and collects the amount of saliva (baseline measurement; T0); then the intervention is performed Measures, 45 seconds (T1) after the intervention During the test, the nurse took out the ice cubes from the subject's mouth with tweezers and weighed it, and then placed the dry cotton swab at the opening of the sublingual gland in the oral cavity, took it out after 1 minute, and collected saliva. Weigh it with an electronic scale with a minimum weight of 0.01 grams, and assume that 1 gram is equal to 1 milliliter.; Change= (45 second score - baseline score)	baseline and 45 second
Primary	Change from Baseline in Measure Saliva Amount at 90 seconds.	Uses a dry cotton stick to place the sublingual gland opening in the subject's oral cavity for 1 minute, and collects the amount of saliva (baseline measurement; T0); then the intervention is performed Measures, 90 seconds (T2) after the intervention During the test, the nurse took out the ice cubes from the subject's mouth with tweezers and weighed it, and then placed the dry cotton swab at the opening of the sublingual gland in the oral cavity, took it out after 1 minute, and collected saliva. Weigh it with an electronic scale with a minimum weight of 0.01 grams, and assume that 1 gram is equal to 1 milliliter.; Change= (90 second score - baseline score)	baseline and 90 second
Primary	Change from Baseline in Measure Saliva Amount at 135 seconds.	Uses a dry cotton stick to place the sublingual gland opening in the subject's oral cavity for 1 minute, and collects the amount of saliva (baseline measurement; T0); then the intervention is performed Measures, 135 seconds (T3) after the intervention During the test, the nurse took out the ice cubes from the subject's mouth with tweezers and weighed it, and then placed the dry cotton swab at the opening of the sublingual gland in the oral cavity, took it out after 1 minute, and collected saliva. Weigh it with an electronic scale with a minimum weight of 0.01 grams, and assume that 1 gram is equal to 1 milliliter.; Change= (135 second score - baseline score)	baseline and 135 second
Primary	Change from Baseline in Measure Saliva Amount at 180 seconds.	Uses a dry cotton stick to place the sublingual gland opening in the subject's oral cavity for 1 minute, and collects the amount of saliva (baseline measurement; T0); then the intervention is performed Measures, 180 seconds (T4) after the intervention During the test, the nurse took out the ice cubes from the subject's mouth with tweezers and weighed it, and then placed the dry cotton swab at the opening of the sublingual gland in the oral cavity, took it out after 1 minute, and collected saliva. Weigh it with an electronic scale with a minimum weight of 0.01 grams, and assume that 1 gram is equal to 1 milliliter.; Change= (180 second score - baseline score)	baseline and 180 second
