Assessment of Ventilation II: Respiratory Depth and Rhythm01:29

Assessment of Ventilation II: Respiratory Depth and Rhythm

2.3K
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:

Sampling Methods: Overview

1.6K
A sample refers to a smaller subset representative of a larger population. In analytical chemistry, studying or analyzing an entire population is often impractical or impossible. Therefore, samples are used to draw inferences and generalize the whole population. The sampling method selects individuals or items from a population to create a sample. Standard sampling methods include random, judgemental, systematic, stratified, and cluster sampling. 
In analytical chemistry, the choice of...

Physical Assessment of the Respiratory Tract IV: Auscultation

1.8K
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Data Collection by Survey01:07

Data Collection by Survey

8.4K
The systematic method of obtaining and analyzing accurate information of a population is called data collection. A survey is a standard method of data collection that involves collecting information from a target human population about their experience, opinion, or knowledge of a product, service, or process. The responses are recorded and interpreted. The most common survey examples are written questionnaires, face-to-face or telephonic conversations, focus groups, and electronic (e-mail or...

Systematic Sampling Method01:17

Systematic Sampling Method

12.3K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
Systematic sampling is one of the simplest methods...

Data Collection III

The physical assessment examines the patient for objective data that defines the patient's condition, and aids in formulating the nursing care plan. The purpose of physical assessment is a health status appraisal, which includes identifying health problems, and establishing a database for nursing intervention.
The principles to begin the physical assessment include conducting a comprehensive or problem-related history in a quiet, well-lit room, emphasizing privacy and comfort for the...

Area of Science:

  • Speech and Hearing Science
  • Acoustic Analysis
  • Voice Science

Background:

  • The voice range profile (VRP) is a crucial tool for assessing vocal capabilities.
  • Variability in data collection methods can impact the reliability and comparability of VRP results.

Purpose of the Study:

  • To systematically review and quantify data collection variability in VRP measurements.
  • To identify key data points affecting frequency and sound level determination.
  • To propose recommendations for VRP protocol standardization.

Main Methods:

  • Systematic review adhering to Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines.
  • Comprehensive literature search across multiple databases (PubMed, Web of Science, etc.) and hand searching.
  • Inclusion of 54 eligible articles after screening 671 titles/abstracts and reviewing 202 full texts.

Main Results:

  • Extensive variability was found in the methodologies used for VRP data collection across studies.
  • Specific data points influencing frequency range and sound level determination exhibited considerable variation.
  • Eight common acoustic measures were identified for statistical analysis in VRP studies.

Conclusions:

  • Current data collection practices for the voice range profile are highly inconsistent.
