Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

258
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

The Bronchial Tree01:23

The Bronchial Tree

3.4K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

1.7K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Physical Assessment of the Respiratory Tract IV: Auscultation01:28

Physical Assessment of the Respiratory Tract IV: Auscultation

591
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.

Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

436
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Chronic Obstructive Pulmonary Disease01:22

Chronic Obstructive Pulmonary Disease

1.4K
COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Area of Science:

  • Pulmonology
  • Medical Diagnostics
  • Foreign Body Aspiration

Background:

  • Foreign body aspiration can present with varied symptoms, sometimes delaying diagnosis.
  • Identifying the aspirated material is crucial for understanding the event and preventing recurrence.

Observation:

  • Two cases are presented where legible text or numbers were found on aspirated materials.
  • Flexible bronchoscopy was used to retrieve the foreign bodies in both instances.

Findings:

  • In the first case, text on foil packaging identified a candy wrapper aspirated from a metered dose inhaler.
  • In the second case, a serial number on plastic material traced a spare part label aspirated during occupational activity.

Implications:

  • This highlights an unexpected diagnostic method for foreign body aspiration.
  • Recognizing markings on aspirated objects can provide valuable etiological information.
  • This method can aid in determining the precise circumstances and timing of aspiration events.
