lesson 7 Flashcards
- situated posterior to trachea and pharynx and anterior to vertebral column; passes through the diaphragm infront of the aorta to enter the stomach, measuring about 10 inches
(25-30cm).
ESOPHAGUS
- Divided into 3 segments: Cervical, Thoracic and Intraabdominal
- Has 4 points of narrowness: Cricoid, Level of aortic know, Opposite
the crossing of the left bronchus, and Through the diaphragm
ESOPHAGUS
Radiographic examination of the pharynx and esophagus investigate suspected lesion of the heart and great vessels. Also, called
barium swallow
2 PHASED EMPLOYED IN ESOPHAGOGRAPHY
- Filling Phase 1.
- esophagus
distend the lumen of esophagus
Filling Phase
demonstrate mucosal pattern of esophagus
Mucosal phase
ESOPHAGOGRAPHY
PREPARATION:
- Light evening meal
- Remove metallic material
- Wear Patient gown
- Prepare patient psychologically
ESOPHAGOGRAPHY
PROCEDURE:
- Fluoroscopic, spot film in upright position
- May use horizontal/ trendelenberg as
indicated - After spot film, patient is instructed to take
up the CM using the left hand and drink it
(Swallowing several mouthfuls of Ba, so act of
deglutition is observed). - Respiratory stress maneuvers are further
instructed as indicated.
(hold
breath, swallow bolus then performs respiratory maneuver)
Breathing Exercises – Valsalva Maneuver
patient exhales then tries to inhale against close glottis
Meuller Maneuver
compression
paddle provides pressure or may alternate the equipment with prone position. (Wolf’s compression paddle and Bar ray’s compression paddle)
Compression Technique (Wolf Method)
possible regurgitation into the esophagus, patient bends and touches the toes.
Toe-touch maneuver
a pear-shaped organ connected proximally to the
esophagus and distally to the small intestine. In the
absence of food, the stomach deflates inward, and its mucosa and submucosa fall into a large fold called a ruga.
