Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care01:29

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

746
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Endoscopic Studies II: Thoracocentesis

2.5K
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...

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

1.6K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Buoyancy and Stability for Submerged and Floating Bodies01:11

Buoyancy and Stability for Submerged and Floating Bodies

3.6K
In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

955
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Buoyancy01:12

Buoyancy

8.9K
When an object is placed in a fluid, it either floats or sinks. All objects in a fluid experience a buoyant force. For example, a metal ball sinks, while a rubber ball floats. Similarly, a submarine can sink and float by adjusting its buoyancy.  The concept of buoyancy raises several interesting questions. For instance, where does this buoyant force come from? How much buoyant force is required to make an object sink or float? Do objects that sink get any support at all from the...

Area of Science:

  • Physiology
  • Environmental Medicine
  • Diving Medicine

Background:

  • The undersea environment presents unique physiological challenges due to increased pressure and inert gas exposure.
  • Boyle's law explains volume changes in gas spaces, leading to barotrauma (e.g., middle ear, lung overexpansion).
  • Breathing compressed air leads to dissolved inert gas supersaturation, potentially causing bubbles and tissue damage upon ascent.

Purpose of the Study:

  • To review the physiological effects of the underwater environment on the human body.
  • To describe diving-related disorders and their management, including hyperbaric recompression therapy.
  • To provide a basis for assessing fitness to dive for recreational diving candidates.

Main Methods:

  • Review of physiological principles related to pressure and gas laws (Boyle's Law).
  • Description of common diving disorders, including barotrauma and decompression sickness.
  • Discussion of diagnostic and therapeutic strategies, emphasizing hyperbaric chamber treatment.

Main Results:

  • Increased ambient pressure causes gas volume changes, leading to barotrauma.
  • Inert gas supersaturation during ascent can result in bubble formation and decompression sickness affecting various organ systems.
  • Hyperbaric recompression is the standard therapy for decompression sickness.

Conclusions:

  • A thorough understanding of the high-pressure undersea environment is essential for diagnosing and managing diving disorders.
  • Healthcare providers need knowledge of diving physiology to effectively clear individuals for recreational diving.
  • This review serves as a foundational resource for understanding diving medicine and fitness assessment.
