X-ray Imaging01:24

X-ray Imaging

11.0K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Ultrasonography01:17

Ultrasonography

8.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

21.9K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

1.5K
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

    Area of Science:

    • Medical Devices
    • Anesthesiology
    • Airway Management

    Background:

    • Videolaryngoscopes improve glottic visualization during tracheal intubation.
    • The Pentax AWS-s100L (s-100) is a previous generation videolaryngoscope.
    • Advancements in videolaryngoscope technology aim to enhance usability and success rates.

    Purpose of the Study:

    • To evaluate the performance of the new Pentax AWS-s200 videolaryngoscope.
    • To compare the features of the AWS-s200 with the previous AWS-s100L model.
    • To assess the success rate and potential challenges during tracheal intubation using the AWS-s200.

    Main Methods:

    • The Pentax AWS-s200 videolaryngoscope was used in 20 patients.
    • Features such as weight, screen clarity, and USB port were noted.
    • Tracheal intubation success and any difficulties encountered were recorded.

    Main Results:

    • The AWS-s200 is lighter (190g) and has a wider, clearer screen than the s-100.
    • Tracheal intubation was successful in all 20 patients.
    • 10 out of 20 patients experienced difficult intubation, with tube impaction on the right arytenoid being a common issue.

    Conclusions:

    • The Pentax AWS-s200 is a functional videolaryngoscope with improved physical characteristics.
    • The central target mark on the AWS-s200 screen may require adjustment for optimal use.
    • Further investigation into the target mark's positioning is recommended to improve intubation smoothness.
