Using party horns to test respiratory function in patients with dementia

Area of Science:

• Gerontology
• Pulmonary Medicine
• Neurology

Background:

• Maintaining safe eating is crucial for inpatients with dementia.
• Respiratory function is closely linked to swallowing safety.
• Current respiratory function tests may not be suitable for all dementia patients.

Purpose of the Study:

• To evaluate the effectiveness of party horns for simple respiratory function testing in dementia patients.
• To correlate respiratory function, measured by party horn blowing, with cognitive status and lung capacity.
• To explore the utility of party horns in ensuring safe eating activities.

Main Methods:

• Assessed respiratory function in 66 inpatients with dementia using 40-cm and 80-cm party horns.
• Measured forced vital capacity (FVC) and correlated it with Mini-Mental State Examination (MMSE) scores.
• Analyzed the relationship between FVC and the ability to fully extend party horns.

Main Results:

• Forced vital capacity (FVC) showed significant differences based on MMSE scores (P = .000).
• FVC also differed significantly based on party horn blowing ability (P = .000).
• Party horn examination demonstrated a significant correlation with FVC (regression coefficient: .562).

Conclusions:

• Party horns are effective, simple tools for assessing respiratory function in early-stage dementia.
• This method can help identify patients needing breathing rehabilitation to support safer eating.
• The party horn test offers a practical approach to improve patient safety and care.
