BOURDON GAUGE

A Bourdon gauge is a mechanical device invented by Eugene Bourdon in 1849 that measures gas or liquid pressure by observing the movement of a C-shaped or coiled flattened metal tube, called the Bourdon tube. When pressurized fluid enters the tube, it tries to straighten, moving a linked pointer across a calibrated dial to indicate the pressure. This inexpensive, reliable, and widely used instrument is still a staple in various industrial and engineering applications.

How it Works

The Bourdon Tube: At the heart of the gauge is a curved, flattened tube sealed at one end.

Pressure Application: The fluid or gas to be measured enters the open, sealed end of the tube.

Deformation: As the internal pressure increases, the tube attempts to uncoil and straighten out.

Mechanical Linkage: This movement of the tube's free end is connected to a linkage and gear mechanism.

Indication: The gears amplify the small movement, causing a pointer to rotate around a dial, which is marked with pressure units (e.g., PSI, bar).

Key Features
Widespread Use: Bourdon gauges are common in many industries, including manufacturing, engineering, and even steam locomotives, due to their reliability and ability to measure high pressures.

Range: They can measure pressures from low values (e.g., 10 mmHg) up to very high pressures (e.g., 100,000 psi).

Simplicity: The design is robust and straightforward, which contributes to its cost-effectiveness and reliability.

Types: While the C-shaped tube is common, Bourdon tubes also come in spiral and helical shapes for higher pressure applications.

Materials: The tubes are typically made from elastic materials like phosphor-bronze or silicon-bronze, chosen for their mechanical properties and corrosion resistance.

Property insert an IV

To properly insert an IV, first prepare supplies and the patient by performing hand hygiene, applying gloves, and selecting a suitable vein. Then, prepare the site by applying a tourniquet, cleaning the skin with an alcohol pad, and stretching the skin to stabilize the vein. Next, insert the IV catheter at a 30-degree angle with the bevel up, advancing it until blood flashes back into the chamber. Once the flashback is seen, lower the angle, advance the catheter, and slide it off the needle into the vein while pulling the needle back. Finally, advance the catheter until the hub is at the skin, then apply a secure dressing and flush the catheter with saline to confirm placement and patency.

1. Patient & Site Preparation
Perform hand hygiene: and apply gloves.
Explain the procedure: to the patient to reduce anxiety.

Position the patient's arm: comfortably and apply a tourniquet** 10-15 cm above the chosen vein.
Select a suitable vein: and stretch the skin taut with your non-dominant hand to stabilize it.
Cleanse the skin: over the insertion site with an alcohol wipe, moving in outward, circular motions, and allow it to dry completely.

2. Catheter Insertion
Hold the IV catheter
with your dominant hand, ensuring the bevel of the needle is facing upward.
Insert the catheter
into the vein at a 30-degree angle.
Advance the needle
slowly until you see a "flash" of blood in the catheter's flashback chamber.
Lower the angle
to a shallow 10-15 degrees and advance the catheter over the needle into the vein.

3. Securing the IV
Slide the plastic catheter: off the needle into the vein.
Withdraw the needle, ensuring the catheter stays in the vein.
Advance the catheter: until the hub is at the skin.
Release the tourniquet .
Apply a secure dressing: to hold the catheter in place.
Attach a normal saline flush: to the extension and flush the line to check for patency.

Tactical Emergency Casualty Care (TECC)

is a scenario-based training program for civilian responders to provide medical care in high-threat environments like active shooter events or mass casualties. TECC teaches how to integrate with security personnel, prioritize bleeding control and airway management, and manage casualties through three phases: care under fire, tactical field care, and tactical evacuation care. The training is hands-on, uses realistic simulations, and prepares individuals to improve patient outcomes in critical situations.

What TECC Teaches
Care under fire: Providing immediate life-saving care while the threat is still present.
Tactical field care: Delivering care in a less dangerous environment after the threat has been suppressed.

Tactical evacuation care: Continuing care while the patient is being transported from the incident.
Integration with security: Working effectively with police and other protection personnel in hostile situations.

Bleeding control: Using tourniquets and other methods to stop severe bleeding, a leading cause of preventable death.

Airway management: Addressing obstructed airways to ensure the casualty can breathe.
Integration of intravenous (IV) lines: Establishing IV access for fluid or medication delivery.

Who is TECC For?
* Emergency Medical Services (EMS) practitioners
* Police officers
* Military and reservist personnel
* Security professionals
* Fire and rescue volunteers
* Nurses and other medical professionals
* Anyone called upon to respond to a mass casualty or active shooter event

Why is TECC Important?

Improves patient outcomes: The training provides the knowledge and skills to significantly improve patient survival rates in civilian tactical environments.

Prepares for real-world events: It offers practical, hands-on experience to build confidence and competence for high-stress situations.

Standardized approach: TECC courses adhere to guidelines established by the Committee for Tactical Emergency Casualty Care (CoTECC), ensuring a consistent and evidence-based approach.

BASIC TRAUMA LIFE SUPPORT

A Basic Trauma Life Support (BTLS) course provides healthcare professionals with essential skills and knowledge for the rapid assessment and management of traumatic injuries in pre-hospital settings, covering areas like airway management, hemorrhage control, and shock management through hands-on training. While BLS (Basic Life Support) focuses on cardiac and respiratory emergencies, BTLS is specifically tailored to trauma, though some organizations offer a combined Basic Life Support with First Aid course.
Key Aspects of a Basic Trauma Life Support (BTLS) Course.

Focus: Provides specialized training for the pre-hospital care of trauma patients.

Skills Developed: Participants learn how to rapidly assess patients, control bleeding (hemorrhage), protect airways, manage shock, stabilize spinal injuries and fractures, and perform basic life support measures.

Learning Format: Courses often include comprehensive theoretical knowledge and intensive, hands-on practical training.

Target Audience: Designed for healthcare professionals and public safety personnel who may encounter trauma emergencies in the field.

Distinction from Basic Life Support (BLS)

BLS: A general set of life-saving medical procedures for emergencies like cardiac arrest and respiratory failure, applicable to a wide range of patients (adults, children, infants) and setting.

BTLS: A more focused program that builds upon basic life support to address the unique and complex challenges of traumatic injuries, such as severe bleeding and internal injuries.

How to Find a Course
Professional Training Providers: Search for reputable training organizations like Stepsuretraining or AMREF Flying Doctors that offer BTLS certification.

Professional Organizations: Look for courses offered by organizations involved in pre-hospital care and trauma management.
