Answer 23

• Blood
• Loss of Consciousness
• Pulse
• Skin Colour
• Capillary Refill
• Heart rate

Note: Blood in water looks like there is a lot of blood and also car seats absorb a lot of blood.

Question 24

Details of Direct Pressure?

Answer 24

Apply Direct Pressure (with a Pad) to the direct point of blood loss. Roll up a dressing so there is “Point” load over the wound to apply direct pressure.
When placing the bandage as it passes over the wound area twist the bandage 180Deg over the dressing to apply greater direct pressure to the wound.

Question 25

Describe Indirect pressure to stop external haemorrhage

Answer 25

``` For Femoral (leg) use your knee. Put knee in groin with a slight twist. Apply direct pressure while applying Tourniquet. ```

Question 26

Will Tourniquet's work on lower limbs

Answer 26

No - The veins and arteries run through the two bones, so tightening will only push against the bones.

Question 27

Tourniquets are applied...

Answer 27

- If you can see the wound then 4 fingers above the wound. This is with the FRNSW issued Torniquets. - IF you can't see the wound then High, Wide and Tight - Veins and arteries can spring back so put Tornos high to ensure cutting off blood. - Also they are the last option to be used if direct pressure is not working. They are very painful and get worse as time goes on. - Remove clothing from the limb and apply directly to the skin. - Do not remove the Tourniquet. If not working add another Torno Higher up or tighten. - Tighten until bleeding stops then do extra half turn on the "WIndless" then lock in.

Question 28

Can a Triangular bandage be used as a Tourniquet?

Answer 28

Yes. Needs to be at least 5cm wide. Tie around limb, Put knot in it. Put an improvised windless (piece of bar, screwdriver, torch, Trauma shears) in knot area then rotate. Tie Windless off then put another triangular bandage around the whole thing.

Question 29

How do you address internal Haemorrhage?

Answer 29

- Direct and indirect pressure. - Get them to a hospital ASAP. - Where bones are involved get the two ends back together. - If the Femur, splinting can help stop/reduce the blood flow.

Question 30

What are the signs of a Pelvis Fracture?

Answer 30

Feet splay out. "Open book" pelvis fracture. Do not roll the casualty if this has occurred. If have to roll do not lift the knee, but rather have 3 people with alternating hands. Put Pelvic binder on.

Question 31

What is the procedure for putting on an improvised pelvic binder?

Answer 31

1) Bring feet together and tie together with a bandage.. 2) Put sheet folded up under the arch of back. 3) Slide the sheet down under the pelvis. 4) Pull around and tie a knot with the sheet. Add a windless (bar etc) and tighten like a torno. 5) Tie the windless off so it does not loosen.

Question 32

Jaw Thrust - If doing from the top of the head (casualty on back) brace your thumbs on their cheeks. - if from in front place thumbs on chin and fingers around jaw and pull forward.

Question 35

What's the volume output of a BVM? What's the volume range of lungs?

Answer 35

- BVM holds 1500mls - Lungs 400-600ml Do breaths slowly when using a BVM and squeeze until you see the chest rise. - place the mask on the chin first, then place on nose. Try to do a jaw thrust with other fingers. - Can use an adult mask on a child. Reverse the mask so the narrow part is on the chin. Be mindful of the amount of air being administered.
