Medical Errors Easily preventable medical errors kill as many as 195,000 people per year in U. To "do no harm", the radiographer can first check and recheck all the steps required to accomplish a specific imaging examination. A major factor in limiting errors in imaging examinations is effective communication between radiographers, patients, and staff. The radiographer can also prevent errors in imaging examinations by following the established protocols and procedures for a particular medical facility. Individual patient circumstances often require that the radiographer adapts the routine procedure for a particular examination but any extreme variation should be explained in the examination documentation. One should never become so overwhelmed that there is no time to check technical factors, patient positioning, or adhere to standard radiation safety measures. Although time is of the essence during imaging examinations, especially trauma care, the radiographer should remember that the time spent on "doing the work right, the first time", will more likely result in the production of diagnostic quality images. A simple yet effective way to limit errors in imaging examinations is to maintain communication between co-workers, patients, physicians, and all support staff. To summarize the importance of preventing errors in imaging examinations, the radiographer should: Review and check all paperwork related to a imaging examination just finished to determine that all documentation is complete before moving on to another patient; Concentrate on the task at hand by focusing on one patient at a time; Read each imaging request thoroughly before preparing for the imaging examination; Develop a routine approach to preparing for each imaging examination; and Review the images to determine if the required facility standards for quality have been met. Obligations to Protect the radiographer has moral, ethical, and legal obligations to protect the public, patients, co-workers, staff, and self from harm while in the service of providing imaging services. All personnel must follow recognized universal practices when participating in or performing imaging examinations. There are unlimited contacts for disease transmission and cross infection among the many people who enter a medical facility. Infection can spread from a single focal point or person of contamination to many other parts of the medical care chain and the general public. Nosocomial infections, often called opportunistic infections, are a group of disease causing organisms that are often drug resistant and extremely pathogenic organisms. These occur primarily in hospitals and medical care settings and result from infections in wounds and in the urinary and upper respiratory tracts. Radiographers are responsible for preventing the spread of microorganisms to others and for protecting themselves from contamination. The total number of infectious organisms can be reduced or diluted to a harmless level by such tasks as hand washing before and after attending each patient, proper disposal of contaminated items, and routine cleaning of imaging equipment and accessories. Radiographers should also practice infection control and follow standard precautions at all times. Medical Equipment As has been mentioned previously, imaging examinations of musculoskeletal structures represents a major percentage of the daily workload in imaging facilities. It is important for the radiographer to recognize common life support and other essential medical equipment 45 that may be within the patient or somehow attached to the patient and must be dealt with during mobile bedside imaging examinations. Tubes, lines, and catheters are essential in treatment of various conditions of the respiratory and circulatory systems. External apparatus such as tubing, clamps, and syringes often lie on or under the patient and the radiographer must use care when positioning the patient to ensure that these are excluded from the images. The patient may have ventilator support tubing, temperature and humidity sensors, or electrocardiogram electrodes and the radiographer should not disturb these during the imaging examination. Pleural devices such as thoracotomy (chest) tubes allow drainage of air (higher chest placement) or fluid (lower chest placement) from the thoracic cavity and allow the lungs to inflate. Such devices consist of a large plastic tube, which is inserted through the chest wall between the ribs. The normally positioned tube lies on the surface of the expanded lung, between the visceral and parietal pleurae. Endotracheal intubation is a lifesaving procedure but can also be life threatening if the tube is incorrectly positioned. In adults, the tip of the tube should be situated approximately 5 cm above the tracheal carina. When advanced too far, the endotracheal tube usually enters the right main bronchus, causing various combinations of hyperinflation and atelectasis of the lungs.

It is clear that there is benefit in maintaining strength and flexibility in the trunk well into the elderly years arrhythmia blogs buy cardizem 120mg free shipping. Contribution of the Trunk Musculature to Sports Skills or Movements the contribution of the back muscles to lifting has been presented in an earlier discussion arteria ethmoidalis posterior discount cardizem 120 mg fast delivery. Likewise hypertension 4 stages buy cardizem 120mg lowest price, the contribution of the abdominals to a sit-up or curl-up exercise was evaluated blood pressure chart and pulse buy generic cardizem 120mg line. At touchdown, the trunk flexes toward the side of the limb making contact with the ground. It also moves back, and both of these movements are maximum at the end of the double support phase. After moving into single support, the trunk moves forward while still maintaining lateral flexion toward the support limb (91). As the speed of walking increases, there is a corresponding increase in lumbar range of motion accompanied by higher muscle activation levels (16). For running, the movements in the support phase are much the same, with trunk flexion and lateral flexion to the support side. One difference is that whereas in walking, there is trunk extension at touchdown; in running, the trunk is flexed at touchdown only at fast speeds (90). For a full cycle in both running and walking, the trunk moves forward and backward twice per cycle. Another difference between walking and running is the amount and duration of lateral flexion in the support phase. In running, the amount of lateral flexion is greater, but lateral flexion is held longer in the maximal position in walking than in running (91). There is one full oscillation of lateral flexion from one side to the other for every walking and running cycle. As contact is made with the ground in both running and walking, there is a burst of activity in the longissimus and multifidus muscles. This activity can begin just before contact, usually as an ipsilateral contraction to control the lateral bending of the trunk. It is followed by a contraction of the contralateral erector spinae muscles, so that both sides contract (90). There is a second burst of activity in these muscles in the middle of the cycle, occurring with contact of the other limb. In the first burst of activity, the ipsilateral muscles are more active, but in this second burst, the contralateral muscles are more active (90). The activity of the erector spinae muscles coincides with extensor activity at the hip, knee, and ankle joints. The lumbar muscles serve to restrict locomotion by controlling the lateral flexion and the forward flexion of the trunk (90). Cervical muscles serve to maintain the head in an erect position on the trunk and are not as active as the muscles in other regions of the spine. A more thorough review of muscular activity is provided for a topspin tennis serve. There is considerable activity in the abdominals and the erector spinae in the tennis serve. The most muscular activity is in the descending wind up and the acceleration phase (21). There is also considerable coactivation of the erector spinae and the abdominals to stabilize the trunk when it is brought back in a back arch in the descending windup and the subsequent acceleration. Both the internal and external oblique muscles are the most active of the trunk muscles. Because both the erector spinae and the abdominals are responsible for lateral flexion and rotation, there is unilateral activation of muscles to initiate left trunk lateral flexion and rotation to the right and left. Forces Acting at Joints in the Trunk Loads applied to the vertebral column are produced by body weight, muscular force acting on each motion segment, prestress forces caused by disk and ligament forces, and external loads being handled or applied (48). The muscleless lumbar spine can withstand a somewhat higher force (>100 N) before buckling (64).

That is arteriovenous malformation buy cardizem 120mg without a prescription, the foot rolls over its lateral border pulse pressure heart failure purchase 120 mg cardizem mastercard, stretching the ligaments on the lateral side of the ankle hypertension hereditary purchase cardizem 180mg amex. This injury occurs when the tibialis anterior pulls on its attachment site on the tibia and on the interosseous membrane between the tibia and the fibula blood pressure chart pulse generic 180mg cardizem mastercard. Sites of avulsion fractures in the pelvic region include the anterior superior spine (a), anterior inferior spine (B), ischial tuberosity (C), pubic bone (D), and lesser trochanter (e). Another site exposed to high tensile forces is the tibial tuberosity, which transmits very high tensile forces when the quadriceps femoris muscle group is active. This tensile force, if sufficient in magnitude and duration, may cause tendinitis or inflammation of the tendon in older participants. In younger participants, however, the damage usually occurs at the site of tendon­bone attachment and can result in inflammation, bony deposits, or an avulsion fracture of the tibial tuberosity. Osgood­Schlatter disease is characterized by inflammation and formation of bony deposits at the tendon­bone junction. Therefore, different bones and different sections in a bone respond to tension and compressive forces differently. For example, the tibia and femur participate in weight bearing in the lower extremity and are strongest when loaded with a compressive force. The fibula, which does not participate significantly in weight bearing but is a site for muscle attachment, is strongest when tensile forces are applied (43). An evaluation of the differences found in the femur has uncovered greater tensile strength capabilities in the middle third of the shaft, which is loaded through a bending force in weight bearing. In the femoral neck, the bone can withstand large compressive forces, and the attachment sites of the muscles have great tensile strength (43). Shear Forces Shear forces are responsible for some vertebral disk problems, such as spondylolisthesis, in which the vertebrae chapter 2 Skeletal Considerations for Movement 43 slip anteriorly over one another. In the lumbar vertebrae, shear force increases with increased swayback, or hyperlordosis (22). The pull of the psoas muscle on the lumbar vertebrae also increases shear force on the vertebrae. Examples of fractures caused by shear forces are commonly found in the femoral condyles and the tibial plateau. The mechanism of injury for both is usually hyperextension in the knee through some fixation of the foot and valgus or medial force to the thigh or shank. In adults, this shear force can fracture a bone as well as injure the collateral or cruciate ligaments (37). In developing children, this shear force can create epiphyseal fractures, such as in the distal femoral epiphysis. The mechanism of injury and the resulting epiphyseal damage are presented in Figure 2-28. The effects of such a fracture in developing children can be significant because this epiphysis accounts for approximately 37% of the bone growth in length (15). Compressive, tensile, and shear forces applied simultaneously to the bone are important in the development of bone strength. Figure 2-29 illustrates both compressive and tensile stress lines in the tibia and femur during running. For example, during gait, the lower extremity bones are subjected to bending forces caused by alternating tension and compression forces. The femur bends both anteriorly and laterally because of its shape and the manner of the force transmission caused by weight bearing. This is commonly produced by a valgus force applied to the thigh or shank with the foot fixed and the knee hyperextended. Although these bending forces are not injury producing, the bone is strongest in the regions where the bending force is greatest (46). Typically, a bone fails and fractures on the convex side in response to high tensile forces because bone can withstand greater compressive forces than tensile forces (43).
