There are several basic rules of band-aid to follow when applying a bandage, which make it both easier to put on and more comfortable for the casualty.
What is the aim of band aid?
In general, the principal purpose of bandaging is to apply pressure over dressing. However, there are various ways in which bandaging may be used
- To control bleeding.
- To provide support for a joint or limb.
- To hold a dressing or splint in place.
- To restrict movement.
- To help lift or carry a casualty.
In an emergency, a bandage can be improvised by using a tie, scarf, belt, or a pair of tights. It is also possible to use any piece of fabric, provided it is clean and also made of a non-fluffy material.
Implement the bandage when the casualty is seated or lying down.
Sit or stand in front of the injury.
Always work from the casualty’s injured side.
When applying a conventional bandage
Check that the injured part is well supported in the position in which it is to remain once bandaged.
If the casualty is lying down, make sure you pass the bandage beneath the natural hollows of the body. You can then ease it gently into the desired position.
A bandage should be tight enough to fulfill its required task. However, it should not be so tight as to impede the circulation.
Check that the bandage is not becoming too close to the damaged area will start to swell due to the injury. If the bandaging is too tight, you may be restricting the circulation. The symptoms and signs of restricted circulation which you should look out for are:
- Tingling or numbness in the fingers or toes.
- Unusually pale or blue fingers or nailbeds.
- Absent or weak pulse in the injured limb, compared with that on the uninjured side.
- If you are wrapping an arm or a leg, make sure that the tips of fingers and toes remain visible, as they are a good check for the circulation.
- If you are securing a bandage with a knot, always use a reef knot.
- The knot should not be tied over the dressing if there is a foreign body in the wound.
- If the aim is to restrict movement, tie the knot(s) on the uninjured side. If both sides are injured, make the tie in the middle, where it will not be uncomfortable.
Roller band aid
Roller band aid can be used in various circumstances, including
- To keep a dressing in place.
- To apply pressure and control bleeding.
- To support a sprain. They usually come in 5m rolls, in a choice of different widths. The required width depends on the part of the body that is injured.
- Finger: 2.5 cm.
- Hand: 5 cm.
- Arm: 5-6 cm.
- Leg: 7.5-9 cm.
- Trunk: 10-15 cm.
How to apply a roller band aid?
Put the tail of the bandage on the limb and work a firm, oblique turn to hold it in place.
Work a series of parallel spiral turns, gradually working up the limb and allowing each turn to cover two-thirds of the previous one.
To finish, cut off the excess bandage and fold in the end. Secure it with adhesive tape or a safety pin. 4. In the absence of either or these, allow an extra 15cm of bandage and cut this into two free ends. Tie these together both at the bottom of the split and then again around the limb to secure.
Triangular band aid
- Triangular band aid can be used for
- To make a sling.
- To secure a light dressing over the head.
- To ensure a hand, foot, or scalp dressing.
- Folded into a pad, as improvised dressings.
- To secure splints.
- To support and immobilize limbs.
- To immobilize feet and ankles.
Applying a triangular band aid
The following steps are used when using a triangular hand bandage. The same method can be utilized for wrapping an injured foot.
- With the injury facing upwards, place the dressing under the casualty’s hand, so that the base is under the wrist and the point is furthermost from the victim.
- Bring the end up over the hand to the wrist.
- Take the ends around the side and across each other. Tie the two ends together below the point, using a reef knot.
- Bring the point over the knot and fasten in position, either by tucking it in well or with a safety pin.
The following steps are used when applying a triangular head bandage.
- Fold in a small hem along the base of the dressing and place this across the forehead, with the two ends passing just above the casualty’s ears and the point hanging down the back of the neck.
- Cross the two ends over each other in the nape of the neck.
- Bring the two ends round to the forehead and tie a reef knot over the hem you made in the base.
- Gently pull on the point with one hand to take up any slack, while steadying the head with the other.
- Bring the point over the head and fasten to the top of the bandage, using a safety pin. Bandaging techniques are best learned by trying them out on a friend.
Tubular band aid
These are unique tube-shaped bandages for use on injured damaged joints, fingers and toes. Light dressings on fingers and toes can also be held in place with tubular gauze, a roll of seamless gauze which is put on using a unique applicator (pro-vided with the gauze) and usually held in place with adhesive strapping.
TYING A REEF KNOT
- Pass the left end over the right end, and under.
- Pass the right end over the left end, and under.
- Pull the two ends tight.
