Summary
Phonation threshold pressure effectively detects vocal fatigue. Short vocal tasks can elicit fatigue, suggesting a need for standardized assessment protocols in clinical practice and research.
Area of Science:
- Speech and Hearing Sciences
- Voice Science
- Clinical Research
Background:
- Vocal fatigue is a growing concern impacting voice professionals.
- Objective and subjective measures are needed for accurate assessment.
- Identifying effective elicitation tasks is crucial for research.
Purpose of the Study:
- To identify sensitive measures for assessing vocal fatigue.
- To determine tasks that effectively elicit vocal fatigue.
Main Methods:
- A scoping review of 17 studies was conducted.
- Databases searched included Cochrane, Medscape, PubMed, and Google Scholar.
- Data on respiratory, laryngeal, and self-perceptual measures and elicitation tasks were extracted.
Main Results:
- Phonation threshold pressure (PTP) was the most consistent indirect respiratory measure for vocal fatigue.
- Laryngeal measures showed inconsistent responses, except for mean fundamental frequency in healthy individuals.
- Short-duration vowel tasks effectively elicited vocal fatigue.
Conclusions:
- PTP is a reliable indirect measure for vocal fatigue.
- Further research on respiratory patterning and ventilation measures is needed.
- Short-duration tasks show promise for eliciting vocal fatigue and require further investigation.

Respiratory capacities are crucial indicators of lung function, representing the maximum amount of air an individual's respiratory system can handle during various breathing phases.
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...

Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...

The respiratory system is responsible for the intake of oxygen and the expulsion of carbon dioxide from the body. Respiratory volumes describe the volume of air in the lungs at different phases of the respiratory cycle. Tidal volume is the air breathed in and out during normal, quiet breathing. Inspiratory reserve volume is the air that can be forcefully inspired beyond the tidal volume. In contrast, expiratory reserve volume refers to the air that can be expelled from the lungs after a normal...

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...
