Chapter 3: Chest; starred slides soft tissue neck Flashcards
What is the carina?
a hooklike process on the last cartilage of the trachea
The trachea divides/bifurcates into what at the carina?
right primary bronchus and left primary bronchus
What is the pharynx?
Musculo membranous tubular structure that’s about 5 inches in length. It serves as a passage for air and food
Where is the larynx located?
in front of the vertebrae and behind the nose, mouth, and larynx
What are the three sub divisions of the pharyngeal cavity?
nasopharynx, oropharynx, laryngeal pharynx
What is the larynx?
organ of voice. It is a movable, tubular structure approximately 1 1/2 inches in length
Where is the larynx located?
below the root of the tongue and in front of the laryngeal pharynx. Suspended from the hyoid bone at the level of superior margin of the fourth cervical vertebra
What is the collimation for an AP soft tissue neck?
12 inches lengthwise and 1 inch behind the skin line on the sides but not more than 10 inches
What should the patients position be for an AP soft tissue neck?
upright or supine
How should the part position be for an AP soft tissue neck?
MSP centered perpendicular midline of the grid
adjust the patients shoulders to lie in the same transverse plane
extend the patients neck slightly
Where should the CR enter for an AP soft tissue neck?
perpendicular through MSP at the level of the laryngeal prominence or manubrium
Is there respiration instructions for an AP soft tissue neck? If so, what are they?
Exposure is made during slow inspiration to ensure trachea is filled with air
What should the collimation be for a lateral soft tissue neck?
10 x 12 inches lengthwise
12 inches lengthwise and 1 inch beyond skin line of the anterior and posterior surfaces
How should the patient be positioned for a lateral soft tissue neck?
seated or standing in lateral position
How should the body part be positioned for a lateral soft tissue neck?
MSP centered parallel midline of the grid
clasp the hands behind the body
rotate the shoulders posteriorly to keep shadow of the arms from obscuring superior mediastinum
extend the neck slightly
Where should the CR enter for a lateral soft tissue neck for the upper airway?
horizontal through MCP
level of the laryngeal prominence
level of jugular notch through a point midway between the jugular notch and the MCP for trachea and superior mediastinum
Where should the CR enter for a lateral soft tissue neck for the trachea and superior mediastinum?
level of jugular notch through a point midway between the jugular notch and the MCP for trachea and superior mediastinum
