In some cases, these carries may not be appropriate. Additional carries are presented here. Always be aware of the risk to both the first aider and the casualty, and the increased danger if a casualty suddenly loses consciousness. Pick-a-back This carry is used for a conscious casualty with lower limb injuries, provided he can use his arms. The casualty must be able to help get into position on your back or be already seated at chair or table height. Crouch with your back between the casualty's knees. Have the casualty hold on around your neck. Support the casualty's legs and lift. Use your leg muscles to stand up, keeping your back straight. If the casualty is to be carried pick-a-back for a long distance, make a carrying seat. Make a large adjustable loop from a strap or belts. Put your arm through the loop, arranging it behind your neck and down the front of your shoulders. Leave the bottom half of the loop free at the back aboutthelevelofyourbuttocks Pass the casualty's legs through the bottom of the loop; one on each side. Position the loop under the casualty's buttocks, adjusting it for a good carrying position and proper weight distribution. 2 Use the cradle carry to lift children and lightweight adults. Kneel on one knee at the casualty's side. Place the casualty's arm around your neck as you support the back and shoulders. Pass your other arm under the knees to grasp the thighs. Ensure a solid footing and place the feet apart for good balance. Lift using your legs, keep your back straight, and your abdominal muscles tense. The fire fighter's carry is used for casualties who are helpless and are not too heavy for the rescuer. With the casualty lying face up in front of you, stand with your toes against the casualty's toes. Grasp her wrists and pull her upward and forward. Maintain a grip on one wrist as you turn and bend to catch the casualty's upper body across your shoulder. The lifting manoeuvre is a continuous, smooth motion to bring the casualty through a sitting position to an upright position, finishing with the casualty draped over your shoulder. Adjust the weight across your shoulders, with the casualty's legs straddling your shoulder. Pass your arm between the casualty's legs and grasp her wrist. This will stabilize the casualty on your shoulders and leave your other hand free. A casualty, who is unable to support his upper body, can be carried by two rescuers, using the two-hand seat. The rescuers crouch on either side of the casualty. Each rescuer reaches across the casualty's back to grasp his clothing at the waist on the opposite side. Each rescuer passes his other hand under the thighs, keeping his fingers bent and holding padding to protect against the fingernails. Hook the bent fingers together to form a rigid seat. Alternatively, the rescuers can hold each other's wrists. The rescuers lift with their legs, keeping their backs straight. Once in the standing position, the rescuers adjust their hands and arms for comfort. When the casualty is securely positioned, the bearers step off together, each using the inside foot. A conscious casualty who can use his hands and arms can be carried on a four-hand seat by two rescuers. Each rescuer grasps his own left wrist with his right hand, then grasps the right wrist of the other rescuer with his left hand to form a square. Tell the casualty to put his arms around the rescuers' shoulders and hoist himself up to permit the bearers to pass their hands under the buttocks to position them under the thighs at a point of balance. Instruct the casualty to hold onto the rescuers' shoulders to keep his balance and support his upper body. The bearers step off together, each using the inside foot. A casualty can be wrapped on a stretcher so that a blanket provides maximum warmth with minimum weight on the casualty. It will also allow easy access to the casualty's wounds if that is necessary during transportation. Place a blanket on the stretcher under the casualty with diagonally opposite corners at the head and feet. Place padding at appropriate places on the blanket to fill the natural hollows at the casualty's neck and back. Centre the casualty on the blanket. Cover the feet with the bottom corner and bring the corner at the head around the neck to the chest. Wrap the legs and lower body with one side. Tuck in the last corner on the opposite side. Q_ Q_ <( Appendix B The Body and How it Works Introduction to anatomy and physiology As a first aider, you don't need a full knowledge of anatomy and physiology. However, you should know the basic structure of the human body and how it functions normally. This chapter describes the terms used in anatomy so that you can be more precise when giving information about a person's condition. It gives a short description of the major organs and functions of the skin, musculoskeletal system, nervous system including the eye, digestive and urinary, circulatory and respiratory systems. Anatomical terms These are the words used to describe where things are on the body and how they relate to each other. Proximal­ closer to the attachment of arm/leg: e.g., the elbow is proximal to the wrist Extension­ straightening a joint Anterior-toward the front of the body Posterior-toward the back of the body Superior-part toward the head ofthe body Flexion-bending a joint Inferior -the part toward the feet of the body Distal-further away from the attachment of arm/leg: e.g., the fingers are distal to the wrist Lateral-away from the midline of body: e.g., the small toe is lateral to the big Medial-nearer to midline: e.g., the big toe is medial to the small toe The skin is an important organ of the body. Its primary functions are to protect the body from environmental hazards and infection, eliminate waste in the form of sweat, help maintain normal body temperature and tell the brain of environmental temperature changes. Environmental control A rich supply of nerves in the skin keeps the brain aware of environmental changes. These nerves are sensitive to heat, cold, pain and touch, and they transmit these sensations to the brain. The skin helps the body adjust to its environment and protects it from extreme temperatures. In cold temperatures, blood vessels constrict to reduce blood flow near the surface of the skin. This helps prevent loss of heat from the body core. The fatty layers under the skin insulate the body to keep in body heat. In hot temperatures, the blood vessels near the skin surface dilate (get larger), allowing more blood flow near the skin. This cools the body by moving heat from the core to the surface, where it either radiates from the body, or is used to evaporate perspiration, having a cooling effect. Functions of the skin To protect the body from bacterial invasion To help control body temperature To retain body fluids To help eliminate waste products through perspiration To insulate the body dermis subcutaneous tissue,----. muscle = Musculoskeletal system The musculoskeletal system is the framework of the body within which organs and body systems function. This framework includes bones, muscles, tendons and ligaments. Bones act as levers for muscle action; muscles shorten to produce movement; tendons attach muscles to bones; ligaments attach bones to bones at the joints. The musculoskeletal system protects organs, supports the body, and provides for its movement. Muscles Muscles are made of a special kind of tissue that contracts (shortens) when stimulated by nerve impulses. Generally, body movement is caused by several muscles working in combination­ as some are contracting, others are relaxing. The nerves in the muscles carry impulses to and from the brain. Muscles are classified as either voluntary or involuntary. Voluntary muscles are consciously controlled by the person, meaning they can be contracted or relaxed as the individual wishes. The muscles that move the skeleton are voluntary. Involuntary muscles contract and relax rhythmically without any conscious effort on the part of the person. The heart, which has its own regulating system, is a good example of an involuntary muscle. The diaphragm, a large dome-shaped muscle that separates the chest and abdominal cavities and is used in breathing, has characteristics of both voluntary and involuntary muscles. The contraction of this muscle, and thus the rate of breathing, can be changed at will for short periods of time. The skeleton, made up of bones, forms the supporting structure that gives the body its shape. It also protects many of the organs­ for example, the brain is protected by the skull, the heart and lungs by the ribs, and the spinal cord by the vertebrae. The joints Bone The bones allow body movement by serving as rigid levers for tendons and muscles. The joints are formed where two or more bones come together. Immovable joints allow no movement, as in the bones of the adult skull. Slightly movable joints allow only Ligaments-hold bones together Cartilage-cushionsthe bone ends --.-- Lubricating membrane­ nourishesand lubricatesthe joint structure Capsule-toughcovering over the joint limited movement and are found between the vertebrae and between the pelvis and the spine. Freely moving joints are covered with smooth cartilage to minimize friction, and are held together by bands of strong tissue called ligaments. Spine The spine is divided into five parts as shown in the diagram. There are 33 bones in the spine, called vertebrae. The vertebrae stack on top of each other with discs between them. The discs are made of a tough flexible material and serve as shock absorbers in the spine. All the discs and vertebrae have an opening in the centre such that, when they stack together, there is a long channel that runs from the top to the bottom of the spine. The spinal cord, which carries all nerve impulses to and from the brain, runs through this channel. The spine protects the spinal cord, but if the spine is fractured, broken Parts of the spine Cervical 7 vertebrae Thoracic 12vertebrae Lumbar 5 vertebrae Sacral 5 fused vertebrae Coccygeal 4 fused vertebrae form thetailbone bones, displaced tissue and swelling can damage the spinal cord, possibly causing lifelong disability. Thorax The thorax is made up of the ribs, the 12 thoracic vertebrae and the sternum (breastbone). The thorax protects the organs in the Ribs-12 pairsare attached to the vertebrae in back and either to the sternum, or to each other, in front. Thelowest ribsattach to thevertebrae only, and are called "floating ribs" Sternum-a dagger-shaped bone with the point downward Xiphoid process (tip of sternum}-a strong piece of cartilage.Pressure on thiscartilage candamage underlying organs chest, mainly the heart and lungs. It also provides some protection for the upper abdominal organs, including the liver at the front and the kidneys at the back. Injuries to the bones of the thorax threaten the organs they protect, and can therefore be life-threatening. Skull All the bones of the head make up the skull. The skull gives the head its shape and also protects the brain. When the skull is fractured, the brain may also be injured. cranium-the plate-like bones fuse together during childhood to form a rigid case for the brain facial bones joinwith bones of the craniumto form theeyeand nose cavities whichprotect the eyes and nose upper jaw (maxilla) lower jaw (mandible) Main bones of the skeleton clavicle (collarbone) scapula (shoulder blade) pelvic bone etacarpals (bones in the palm) halanges (bones of fingers) tarsals (ankle bones and part of the foot arch) phalanges (bones of the toes) ibula (little toe side) _"' tibia (shin bone) metatarsals (bones of the foot) Nervous system The nervous system is composed of the brain, spinal cord and nerves. The brain and spinal cord together are called the central nervous system. The nerves that spread out to all parts of the body are called peripheral nerves. The nervous system is sub divided into the voluntary nervous system and the autonomic nervous system. The voluntary nervous system controls functions at the will of the individual. The autonomic nervous system controls functions without the conscious effort of the individual-e.g. heartbeat, breathing, blood pressure, digestion and glandular secretions such as hormones. The peripheral nerves that extend from the spinal cord to all parts of the body are of two kinds-motor nerves and sensory nerves. Motor nerves control movement. Sensory nerves transmit sensations of touch, taste, heat, cold and pain to the brain. Brain The brain, the controlling organ of the body, occupies almost all the space in the cranium. It is the centre of consciousness, memory and thought. It receives information and transmits impulses to all parts of the body for voluntary and involuntary activities. Eyes The eye is the organ of sight. Any injury to the eye is potentially serious and may result in impaired vision or blindness. The quick response of the first aider and the correct first aid may help prevent permanent damage to the eye. Eyelid-movable layersof skinthat providea protective covering for the eye Iris-coloured set of muscleswhich control thesize of the pupil, whic in turncontrolsthe amount of light entering the eye Pupil-opening that letslight into the eye Conjunctiva-smooth, transparent membrane covering the front of the eye and inner eyelids Cornea-thin, transparent front of the eyeball that allowslight to enter the eye Aqueoushumour-the watery fluid filling the space between thecorneaand theiris Lens-changes shape to focus light raysuponthe retina Muscles-used to control eye movement Optic nerve-transmits nerve impulsesto the brain for visual interpretation Retina-light-sensitive layer covering the back of the insideofthe eye. It changes thelight imagesinto nerve impulses Vitreous humour -the clear, jelly-like fluid filling the cavitybehind the lens Digestive and urinary systems The digestive and urinary systems convert food and drink into nutrients for the cells and collect and dispose of solid and fluid waste. The organs of these systems are classified as hollow or solid. The hollow, tubular organs carry digestive and urinary materials. The solid organs are tissue masses with a rich blood supply. Injury to hollow organs may allow the contents to spill out into the abdominal or pelvic cavities, causing infection. Injury to the solid organs can result in severe internal bleeding. Digestive system Liver-contains many blood vessels-averyimportant organ for production of plasma (blood), energy and bile(for fat digestion) Stomach-digests and stores food until it is ready to move on to the intestine Intestines-a tube made up of the small and large intestinesthat functionsto absorb nutrients from digestion, and to collect solid wastes for excretion Small intestine Large intestine Pancreas­ produces digestive juices, and makes insulinto help control blood sugar levels (located behind the stomach) Gall bladder­ stores and releases bile (located under the liver) Rectum (exit for wastes) Urinary system The urinary system removes and collects waste products from the blood and eliminates them from the body in the form of urine. It is made up of the kidneys, ureters, bladder and urethra. Kidneys-huge quantities of blood passthrough the --1--+---=:-j._ kidneyswhich extract waste productsand produce about 2500 ml of urinedaily. They are partiallyprotected by the lowerribsintheback Ureters-tubesthat carries urine to the bladder fromthe kidneys Bladder-a sac whichreceives and holdsurine until it isexcreted Urethra-tube through which urine is excreted to the outside Circulatory system The circulatory system is a complex closed circuit consisting of the heart and blood vessels that circulates blood throughout the body. Blood circulation is essential for distributing oxygen and nutrients to cells, and for collecting waste products from cells for excretion from the body. Heart The heart is a hollow, muscular organ about the size of a fist. It is located in the chest cavity behind the sternum. The heart functions as a two-sided pump, continuously pumping blood to the lungs and throughout the body. It pumps by first relaxing and filling up with blood, then contracting to squeeze or pump the blood out Superior vena cava-large vein that carriesblood from the upper bodyback to the heart Aorta-largest arterythat carriesblood to the body Pulmonary Lungs-a pair of organs which oxygenate the blood; theheart thenpumpsit to thebody Right atriu....---- \--=- !,' collectsthe deoxygenated blood fromthe body lungs oxygenated blood from the lungs Right ventricle-pumps theblood to thelungsfor Inferior vena oxygenation cava-large vein that carriesblood fromthe lower body backto the heart Left ventricle-pumps blood to the body veins-carry blood fromthe lungsto the heart into the blood vessels. To make the heart beat effectively, it has a complex system of nerves. These nerves carry electrical impulses that control the beating of the heart. Blood vessels The blood travels through blood vessels. There are three main types of blood vessels: arteries, capillaries and veins. The arteries are the strongest blood vessels. They carry blood, under pressure, from the heart to all parts of the body. The arteries expand according to the volume of blood being forced through them by the pumping action of the heart, and return to normal size as the heart refills for the next contraction. This pressure wave can be felt as a pulse. The largest artery, the aorta, emerges from the top of the heart. The coronary arteries branch off from the top of the aorta to supply the heart with blood. The smallest arteries are called arterioles and -..rentually form capillaries. Capillaries are the tiny blood vessels that reach every living cell to deliver oxygen, food, etc. and collect waste products. They have very thin walls to allow for the exchange of fluids and gases. Capillaries eventually join to form tiny venules, which in turn form veins. The veins take the blood back to the heart. Veins have thinner walls than arteries and most have cuplike valves that allow blood to flow only toward the heart. Blood Blood is the fluid that circulates through the heart and blood vessels. It transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Blood is composed of plasma, red cells, white cells and platelets-see sidebar. Blood circulation The blood circulation system is a closed loop beginning and ending at the heart. It consists of: Pulmonary circulation-starting at the right side of the heart, blood is pumped to the lungs, where it drops off carbon dioxide and picks up oxygen, and then moves it back to the left side of the heart Systemic circulation-starting at the left side of the heart, blood is pumped to the body, where it delivers oxygen and picks up carbon dioxide, and then moves it back to the right side of the heart Blood components Plasma-pale yellow liquid that carries cells, platelets, nutrients and hormones Red blood cells-carry oxygen White blood cells-protect the body against microbes Platelets-help form blood clots to stop bleeding Blood pressure Blood pressure is the pressure of the blood pushing against the inside walls of the blood vessels. With each heartbeat, there is a wave of pressure that travels throughout the circulatory system. The pressure wave is strong enough to be felt as a pulse at various points in the body, including the wrist (radial pulse), the neck (carotid pulse), and the upper arm (brachia! pulse). Three factors control blood pressure: Blood volume (how much blood is in the body) The capacity and elasticity of the blood vessels The strength of the heartbeat If blood pressure is too low, the body's tissues don't get enough oxygen. This results in shock. Severe bleeding reduces the blood volume, which affects blood pressure. The body tries to compensate for blood loss by constricting the blood vessels and reducing the capacity of the circulatory system. With continued blood loss, however, the body cannot compensate and blood pressure drops. Respiratory system The respiratory system causes air to be drawn in and out of the lungs. The fresh air we breathe contains about 21% oxygen. In the lungs, blood picks up some of the oxygen and releases carbon dioxide. The air we breathe out has less oxygen (about 16%) and more carbon dioxide. The respiratory system has three main parts: the airway, the lungs and the diaphragm. The airway is the passage which air follows to get from the nose and mouth to the lungs. In the lungs, blood drops off carbon dioxide and picks up oxygen. This process is called gas exchange. The diaphragm, a smooth, flat muscle just below the lungs, is used in breathing. Respiratory control Breathing is controlled by the respiratory centre in the brain, Pharynx*-top of the throat/ back of the mouth and nasal Lungs-made up of thousandsof air sacs surrounded by a network of capillaries, and the varioussizes of airtubes Bronchiole*-the air tubesleadin Alveoli-airsacs where gas exchange occurs-the wallsof the alveoli are thin so oxygen and carbon dioxide can be exchanged with the blood Larynx*-containsthe vocal chords.The top isprotected by a flap called the epiglottis that stays open for breathing, but closes whenfood and fluids are being swallowed Diaphragm-strong * Partof the airway muscle that separates the chest from the abdominal cavity-it isdome-shaped when relaxed, as air is being exhaled, and flat whencontracted, as air isbeing inhaled located near the base of the neck. It monitors the amount of oxygen and carbon dioxide in the blood. As the levels of oxygen and carbon dioxide change, the respiratory centre responds by changing the rate and depth of breathing. How much oxygen is used, and how much carbon dioxide is given off, is related to the level of physical activity of the person. As physical activity goes up, more oxygen is used and more carbon dioxide is given off, so the respiratory centre increases the rate and depth of breathing to compensate (the heart rate also goes up). Breathing slows down when less oxygen is needed and less carbon dioxide is being produced. Mechanism of breathing The lungs have no way of drawing air into themselves. Instead, the diaphragm and the muscles between the ribs work together to expand the chest, which in turn expands the lungs. This causes air to be pulled into the lungs. As the breathing muscles relax, the chest returns to its smaller size and air is forced out of the lungs. The lungs are covered with a smooth, slippery tissue called the pleural membrane. It is a continuous, double-layered tissue, one layer attached to the lungs and the other to the inside of the chest wall. The pleura acts as a lubricating layer to allow easy movement between the chest wall and the lungs, and to ensure that the lungs expand with the action of the chest wall.
