Non-adherent dressings are a simple but important part of a well-stocked first aid kit. Unlike adhesive or island dressings, they don’t have an adhesive border, meaning they need to be secured with tape, a conforming bandage or another suitable method.

In this episode, you’ll learn the difference between adhesive island dressings and non-adherent dressings, the advantages and disadvantages of each, and why choosing the correct size matters. We’ll also look at what makes a good minor wound dressing and why the dressing should always be selected to suit the wound — not the other way around.

In this episode, you’ll learn what electrolytes are, why our bodies need them, and how oral rehydration solutions such as Hydralyte® work.

The Glasgow Coma Scale, or GCS, provides a structured way to assess and communicate a patient’s level of consciousness. By assessing eye opening, verbal response and motor response, first aiders and healthcare professionals can build a clearer picture of a patient’s neurological status.

In this episode, you’ll learn how the three components of GCS are scored, what a score between 3 and 15 represents, and why documenting individual eye, verbal and motor scores can be more useful than recording the total alone. We’ll also explore why changes in GCS over time can be an important warning sign of patient deterioration.
