Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

1.0K
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Pulse Assessment Sites01:11

Pulse Assessment Sites

2.3K
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

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.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

    Area of Science:

    • Neuroscience
    • Audiology
    • Biomedical Engineering

    Background:

    • Clinical assessment of the human auditory system is crucial for evaluating cognitive processes.
    • Conventional Auditory Steady State Response (ASSR) and Auditory Brainstem Response (ABR) tests use electroencephalography (EEG) but are obtrusive and lack cochlear dynamics information.

    Purpose of the Study:

    • To develop a more clinically useful approach for auditory health assessment.
    • To investigate the auditory transfer function, encompassing the tympanic membrane, middle ear bones, and cochlear subsystems.

    Main Methods:

    • Development of an integrated in-ear device for auditory health assessment.
    • The device incorporates a sound engine for stimulation and high-density dry-electrode EEG for simultaneous brain activity recording.
    • Investigation of the hearing system's auditory transfer function.

    Main Results:

    • The novel in-ear system offers ease-of-use and enhanced patient comfort.
    • Real-time simultaneous recording of brain activity during auditory stimulation is achieved.
    • The study explores the complex convolution of the auditory transfer function.

    Conclusions:

    • The developed in-ear device represents a significant improvement over conventional auditory evaluation techniques.
    • This technology enhances the clinical utility of EEG-based auditory assessments.
    • The system facilitates a more comprehensive understanding of hearing system dynamics.
