Pulse amplitude and quality01:17

Pulse amplitude and quality

Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

Assessment of Ventilation II: Respiratory Depth and Rhythm

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:
Auditory Perception01:17

Auditory Perception

The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...
Physical Assessment of the Respiratory Tract IV: Auscultation01:28

Physical Assessment of the Respiratory Tract IV: Auscultation

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.

Assessment of Ventilation I: Respiratory Rate

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Summary

Children using cochlear implants (CI) have borderline vocal quality, similar to those using hearing aids (HA) and normal hearing peers. Focus on improving strained voice characteristics and lowering pitch and intensity in CI and HA users.

Area of Science:

  • Audiology
  • Speech-Language Pathology
  • Pediatric Otolaryngology

Background:

  • Prelingual deafness significantly impacts speech development.
  • Cochlear implants (CI) and hearing aids (HA) aim to restore auditory function.
  • Objective vocal quality assessment is crucial for understanding speech production in hearing-impaired children.

Purpose of the Study:

  • To assess objective vocal quality in prelingually deaf children using CI.
  • To compare vocal quality between CI users, HA users, and normal hearing (NH) children.
  • To identify specific vocal characteristics for therapeutic intervention.

Main Methods:

  • Cross-sectional, multigroup posttest-only design.
  • Objective vocal quality measured using the Dysphonia Severity Index (DSI).
  • Perceptual voice assessment conducted using the GRBASI scale.

Main Results:

  • CI users exhibited borderline vocal quality (DSI% = 68%), 2% above normal limits.
  • Perceptual analysis revealed slight hoarseness, roughness, strained phonation, and higher pitch/intensity.
  • No significant objective vocal quality differences were found between CI, HA, and NH children.

Conclusions:

  • Vocal quality in CI and HA users is comparable to NH peers but shows specific characteristics.
  • Intervention should target reducing strained vocalization.
  • Therapeutic strategies should aim to lower pitch and intensity levels in these populations.
