In anteroposterior (AP) views, the positions of the x-ray source and detector are reversed: the x-ray beam enters through the anterior aspect and exits through the posterior aspect of the chest. AP chest x-rays are harder to read than PA x-rays and are therefore generally reserved for situations where it is difficult for the patient to get an ...
After positioning in which the patient sits upright with their arms at the side, with the chest clear of clothing, the four stages of the examination can be carried out. In order to listen to the lungs from the back the patient is asked to move their arms forward to prevent the scapulae (shoulder blades) from obstructing the upper lung fields.
The Trendelenburg position may be used for drainage images during endoscopic retrograde cholangiopancreatography. [10] The Trendelenburg position is reasonable in those with a cord prolapse who are unable to achieve a knee-to-chest position. [11] It is a temporary measure until a cesarean section can be performed. [11]
Lumbar Spine - AP and Lateral +/- L5/S1 view in the UK, with obliques and Flexion and Extension requests being rare. [15] In the US, basic projections include an AP, two Obliques, a Lateral, and a Lateral L5-S1 spot to better visualize the L5-S1 interspace. Special projections are AP Right and Left bending, and Laterals with Flexion and Extension.
The heat escape lessening position (HELP) is a way to position oneself to reduce heat loss in cold water. It is taught as part of the curriculum in Australia, North America, and Ireland for lifeguard and boating safety training. It essentially involves positioning one's knees together and hugging them close to the chest using one's arms.
In medicine, Fowler's position is a standard patient position in which the patient is seated in a semi-sitting position (45–60 degrees) and may have knees either bent or straight. Variations in the angle are denoted by high Fowler , indicating an upright position at approximately 90 degrees and semi-Fowler , 30 to 45 degrees; and low Fowler ...
A KUB is a plain frontal supine radiograph of the abdomen. It is often supplemented by an upright PA view of the chest (to rule out air under the diaphragm or thoracic etiologies presenting as abdominal complaints) and a standing view of the abdomen (to differentiate obstruction from ileus by examining gastrointestinal air/water levels).
The jaw-thrust maneuver is an effective airway technique, particularly in patients in whom cervical spine injury is a concern. The jaw thrust is a technique used on patients with a suspected or possible cervical spinal cord injury and is used on a supine patient. The practitioner uses their index and middle fingers to physically pull the ...
