Three skills to walk away with.

Identify
Steri-Strips, Vetbond, pressure dressings, hemostatics, and tourniquets - and when each fits.
03
Apply
A CAT or SOFTT-W tourniquet correctly under time pressure.

Tissue adhesive
Vetbond - liquid skin
Cyanoacrylate · veterinary tissue adhesive
Definition
A no-prescription veterinary tissue adhesive, chemically identical to Dermabond. One drop holds wound edges together while a flexible, waterproof seal forms in 30 seconds.
In the room
A clean half-inch cut on a finger that would otherwise cost $200 at urgent care. Irrigate, dry, hold the edges, one drop, count to thirty. Falls off naturally in 5–10 days.

Pressure dressings
Israeli bandage
A one-handed pressure dressing designed for self-application, with a built-in pressure bar that maintains compression after the wrap is finished.
01
Open the package; place pad over the wound.
02
Wrap the elastic strap around the limb, threading through the pressure bar.
03
Reverse direction at the pressure bar to apply compression.
04
Tuck the end into the closure clip.

Applying a tourniquet correctly
01
of 04
Place
2–3 inches above the wound
Never on a joint. If the wound is on the lower leg, the tourniquet goes above the knee; if on the forearm, above the elbow.

Tighten
Pull the strap, secure the velcro
Pull the strap as tight as you can by hand and press the velcro down. Most of the constriction comes from the windlass - but a tight starting position matters.
Checkpoint · Strap secured
03
of 04
Twist
Windlass until bleeding stops
Twist the windlass - the rigid bar - until the bleeding stops. Not until it slows. Stops. Then lock the windlass into its clip.
Checkpoint · Bleeding stops

Note
Write the time on the strap
Write the time of application directly on the tourniquet strap, or on the patient's forehead, in permanent marker. The hospital needs to know.

What loses the wound - and what to do instead
What goes wrong
What to do instead
01 · Common
Buying the $7 Amazon tourniquet because it's the same color.
Instead
Spend $30 on a real CAT or SOFTT-W. The knock-offs fail under load.
02 · Common
Placing the tourniquet on a joint.
Instead
Place 2–3 inches above the wound - and above the nearest joint.
03 · Common
Vetbond on a deep, gaping, or contaminated wound.
Instead
Steri-Strips after irrigation, or transport. Vetbond is for clean, shallow cuts.
04 · Common
Removing a tourniquet to 'check' if the bleeding has stopped.
Instead
Leave it. Definitive care happens at the hospital - not in your living room.

Lesson two: wound closure. The cut that's too big for a Band-Aid but not big enough to drive to the ER for is the exact wound this lesson is about.
Transcript
By the end of this lesson you'll recognize when a wound needs more than a bandage, you'll know the four tools that close it, and you'll be able to apply a tourniquet the right way.
Transcript
Vetbond is the tool you wish you'd known about ten years ago. It's chemically the same as Dermabond - what an ER uses on you - but available without a prescription. One drop, hold the edges together thirty seconds, done.
Transcript
When direct pressure isn't enough you reach for a pressure dressing. The Israeli bandage and the OLAES are both designed to be applied with one hand - even to yourself. Each has a built-in pressure bar that maintains compression after you finish wrapping.
Transcript
How you apply a tourniquet matters. Done right it stops a fatal bleed and the limb survives. Done wrong it's either ineffective or causes preventable tissue damage. Four steps.
Transcript
Four mistakes I see again and again with wound closure. The corrections on the right are small changes that matter a lot in the moment.
Transcript
Three things to walk away with. Recognize the signs a wound is beyond a Band-Aid. Stock the five tools that close real wounds. And practice the tourniquet on a willing limb before you ever need it on a hurting one.
