COVID-19 / Coronavirus Outbreak: How To Perform A Bronchoscopy
0 Views •
2020
In pandemic times, medical staff is becoming a key resource in fighting the infection. To achieve the best medical care, relevant techniques and procedures have to be taught to medical staff while reducing the risk of infection. COVID patients often suffer from respiratory insufficiency and increased intrapulmonal secretion. A bronchoscopy is one of the standard procedures for resolving respiratory tract obstruction in intensive care medicine. On the downside, this procedure has a high...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University A common carnival game is to ask people to guess the number of jellybeans packed into a jar. The chances that anyone will get the exact number right are low. But what about the chances that someone will guess 17 or 147,000? Probably even less than the chances of guessing the correct answer; 17 and 147,000 just seem irrational. Why? After all, if the beans cannot be taken out and counted one-at-a-time, how can someone tell that an...

In scientific terms, these abilities are referred to as theory of mind, and this understanding is necessary for activities like giving compliments,...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
0 Views •
2024
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 to...

Here, we present a protocol to navigate the bronchial maze in a structured manner, splitting the bronchoscopy into a stepwise approach-the four landmarks approach.
FAQs
Fiber-optic sensors detect changes in light transmission as the bronchoscope or catheter bends. Those changes provide information about the instrument’s changing configuration, allowing software to reconstruct its three-dimensional shape rather than treating the device as a fixed, straight object. The resulting shape information supports continuous tracking as the instrument advances through branching airways.
The CT-derived airway map provides an anatomical reference for the instrument’s reconstructed position. As the bronchoscope or catheter moves through progressively smaller branches, software displays its location within that mapped airway structure in real time. Combining tracked shape with mapped anatomy helps clinicians guide the instrument toward lesions that lie beyond the central bronchi.
Its navigation is based on fiber-optic shape tracking and a CT-derived airway map, while conventional fluoroscopic guidance uses a different imaging approach. The distinction matters when procedures target lesions beyond the central bronchi, because reconstructing the instrument’s three-dimensional configuration can support precise navigation and may reduce dependence on conventional fluoroscopy.
A typical workflow begins with a CT-derived map of the airway tree. The clinician then advances a bronchoscope or catheter through branching airways while software displays the instrument’s tracked position and shape in real time. After the device is guided toward a peripheral pulmonary lesion, targeted sampling can be performed for diagnostic evaluation.
The approach is especially relevant when clinicians need to evaluate peripheral pulmonary nodules or masses that are difficult to reach through the central bronchi. By supporting navigation through branching airways, it can help direct sampling toward these lesions. This makes it useful for the minimally invasive evaluation of suspected lung disease and diagnostic decision-making.
Successful navigation can produce a targeted sample from a peripheral pulmonary nodule or mass for diagnostic assessment. Beyond the sample itself, the tracked position and instrument configuration support procedural precision by showing how the device is positioned within the mapped airways. This makes the method relevant to minimally invasive evaluation of suspected lung disease.
