Respiratory System Abnormal Finding II: Palpation and Auscultation

Respiratory System Abnormal Finding II: Palpation and Auscultation

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

The Cochlea

The Cochlea

The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Cardiovascular System Abnormal Findings II: Auscultation

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.
Abnormal Heart Sounds

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Hearing

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

The Auditory Ossicles

The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Summary

This summary is machine-generated.

Children with bilateral cochlear implants struggle with voice control, similar to those with unilateral implants. However, voice quality improves with longer use of bilateral cochlear implants and increased time in sound.

Area of Science:

Audiology
Speech-Language Pathology
Pediatric Otolaryngology

Background:

Bilateral cochlear implants (CIs) aim to restore hearing in children with severe to profound hearing loss.
Acoustic voice outcomes in pediatric bilateral CI users are not well-established and require comparison to normative data.

Purpose of the Study:

To measure acoustic voice outcomes in children with bilateral CIs.
To compare these outcomes with established pediatric norms and unilateral CI users.
To investigate the influence of CI duration, age at implantation, and time in sound on voice parameters.

Main Methods:

Cross-sectional study conducted at a pediatric tertiary care cochlear implant center.
Acoustic voice testing performed on 27 children (aged 3-15 years) with bilateral CIs using Computerized Speech Lab and Multi-Dimensional Voice Program.
Comparison of acoustic results with normative data and data from unilateral CI users.

Main Results:

Children with bilateral CIs showed impaired long-term control of frequency and amplitude perturbation during sustained phonations compared to normative data.
These findings were consistent with previous reports on unilateral CI users.
Improved long-term control of frequency perturbation was observed with increased duration of bilateral CI use and overall time in sound.

Conclusions:

Children with bilateral CIs exhibit difficulties in controlling voice perturbations during sustained phonations, similar to unilateral CI users.
The duration of usable hearing, specifically time in sound, positively influences the improvement of these acoustic voice measures.
