Key Features

• 23-gauge size
  Medium-sized needle, offering a balance between patient comfort and efficient fluid flow.

• Sterile & single-use
  Each needle is individually sealed to maintain sterility and prevent contamination.

• Luer lock / luer slip compatibility
  Fits standard syringes depending on the design, making it widely adaptable in medical settings.

• Stainless steel construction
  Made from high-quality medical-grade stainless steel for strength, sharpness, and smooth penetration.

• Color-coded hub
  The G23 needle hub is typically blue, making identification easy during clinical use.

• Beveled, sharp tip
  Designed for smooth, low-pain insertion.

Benefits

• Strong and puncture-resistant

• Hypoallergenic (safe for people with latex allergies)

• Comfortable with good tactile sensitivity

• Resistant to chemicals, oils, and bodily fluids

• Ideal for long-wear use

• Purpose & Use

  • A non-rebreather mask (NRM) is a high-flow oxygen delivery device used in emergencies or critical care to deliver high concentrations of oxygen (60–100%).

  • Commonly used for patients with severe hypoxia, respiratory distress, or trauma.

  • Designed to prevent exhaled air from mixing with oxygen, ensuring maximum oxygen delivery.

• Structure & Components

  • Mask: fits over the nose and mouth with a soft, flexible cushion for comfort and minimal leakage.

  • Reservoir bag: attached to the mask, holds a supply of oxygen for inhalation.

  • One-way valves:

    • Between the mask and reservoir bag to allow inhalation of pure oxygen.

    • On exhalation ports to prevent rebreathing of exhaled air.

  • Elastic straps: secure the mask to the patient’s face.

  • Oxygen tubing connector: attaches to oxygen sources or flowmeters.

• Performance & Flow Rate

  • Delivers high oxygen concentrations (up to 100%) when properly fitted.

  • Requires oxygen flow of 10–15 L/min to keep the reservoir inflated and ensure effectiveness.

  • One-way valves prevent rebreathing of CO₂, unlike simple masks.

• Advantages

  • Provides maximum oxygen delivery in emergencies without intubation.

  • Simple, lightweight, and easy to apply.

  • Rapidly increases oxygen saturation in hypoxic patients.

  • Disposable and single-patient use reduces infection risk

Indications / Uses

Normal Saline is commonly used for:

• Dehydration

• Shock / hypovolemia

• Fluid maintenance

• Dilution of IV medications

• Flushing IV lines

• Blood transfusion compatibility

• Diabetic ketoacidosis (initial fluid)

• Sodium depletion (hyponatremia)

• Replacing gastrointestinal fluid loss

Contraindications / Use with Caution

• Heart failure (risk of fluid overload)

• Kidney failure (risk of sodium and fluid retention)

• Hypernatremia

• Edema

• Metabolic acidosis (Normal saline may worsen acidosis)
