Equilibrium and Balance01:15

Equilibrium and Balance

6.2K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Anatomy of the Ear01:16

Anatomy of the Ear

11.5K
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...

Alterations in Respiration II01:30

Alterations in Respiration II

2.5K
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

The Vestibular System01:29

The Vestibular System

38.0K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen01:16

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

3.7K
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Atelectasis II: Pathophysiology01:10

Atelectasis II: Pathophysiology

40
Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through...

Summary

Eustachian tube dysfunction is linked to middle ear barotrauma in SCUBA divers. Evaluating and treating Eustachian tube function before diving can prevent alternobaric vertigo and other diving accidents.

Area of Science:

  • Otolaryngology
  • Diving Medicine
  • Aerospace Medicine

Background:

  • Sport SCUBA diving is increasingly popular, leading to a rise in diving-related accidents.
  • Alternobaric vertigo (AV) is a common condition affecting SCUBA divers, often related to middle ear barotrauma.
  • Understanding the link between Eustachian tube function and AV is crucial for diver safety.

Purpose of the Study:

  • To investigate the relationship between Eustachian tube function and the incidence of alternobaric vertigo (AV) in sport SCUBA divers.
  • To assess the progression of vestibular symptoms in divers following an accident.
  • To identify factors influencing the occurrence and persistence of AV.

Main Methods:

  • Compared 44 SCUBA divers with middle ear barotrauma to 20 healthy divers.
  • Utilized sonotubometry and impedance testing to evaluate Eustachian tube function.
  • Categorized divers with accidents into groups with and without AV for comparative analysis.

Main Results:

  • Divers with diving accidents showed significant differences in Eustachian tube function parameters (duration, amplitude, air content) compared to healthy divers.
  • No significant differences in these Eustachian tube function parameters were found between divers with AV and those without AV.
  • Vestibular symptoms resolved immediately after ascent in some divers, while others experienced persistent vertigo/dizziness.

Conclusions:

  • Thorough evaluation of Eustachian tube function is recommended for all SCUBA divers.
  • Treatment of any identified Eustachian tube dysfunction is advised prior to engaging in SCUBA diving.
  • Addressing Eustachian tube issues can help prevent AV and other diving-related barotraumas.
