75
- determines the relative size, shape, position, muscular tone and mobility of all organs. The two organs most dramatically affected by body habitus are the stomach and gallbladder.
Body Habitus
76
- comprises 5% of the majority
- the body is massive built with a broad chest
- the thorax cavity is short resulting in the ribs being almost horizontal
- the lungs are short at the apices and broad at the base
- high diaphragm and low abdominal cavity
- stomach is high and almost horizontal
- gallbladder high and lateral
HYPERSTHENIC (massive)
77
- comprise 50% of the majority
- the stomach lies on the normal position and the gallbladder under the 11th rib
-i t is almost similar to hypersthenic
STHENIC (average)
78
- comprise 35% of the majority.
- this is the modification of the asthenic type but leans forward than the sthenic
- the stomach is elongated, J shape and extends to the iliac crest or below
- the gallbladder is lower and more toward the midline compared to the sthenic type build.
- the large bowel is located lower than in the average habitus, but the splenic flexure may still be found high in the upper left quadrant
HYPOSTENIC (slender)
79
- the opposite extreme is the extremely slender build or asthenic type
- the chest cavity narrow, shallow and quite long, so that the diaphragm lies very low
- the heart is long and slender
- the large bowel folds on itself, and is found very low and toward the midline
- the gallbladder and stomach are both low, vertical and near the midline
- the abdominal cavity is shallow, with its greatest capacity in the pelvic region
ASTHENIC (very slender)

SEVEN LANDMARKS OF THE ABDOMEN
-the most inferior process of the sternum
Xiphoid process (level of T9-T10)
81
SEVEN LANDMARKS OF THE ABDOMEN
- used to locate upper abdominal organs, such as the gallbladder and stomach
Inferior costal (Rib) margin (level of L2-L3)
82
SEVEN LANDMARKS OF THE ABDOMEN
- the most commonly used abdominal landmark and corresponds approximately to the level of the mid-abdominopelvic region , which is also at or just slightly below the level of the umbilicus on most people
Iliac crest (level of L4-L5 vertebral interspace)
83
SEVEN LANDMARKS OF THE ABDOMEN
-can be found by locating the iliac crest, then palpating anteriorly and inferiorly until a prominent projection or “bump” is felt (more prominent on females)
Anterior superior iliac spine (ASIS)
84
SEVEN LANDMARKS OF THE ABDOMEN
-the prominence of the greater trochanter is at about the same level as the superior border of the symphysis
Greater Trochanter
85
SEVEN LANDMARKS OF THE ABDOMEN
- the anterior junction (joint) of the two pelvic bones
-corresponds to the inferior margin of the abdomen
-palpation of this area may be embarrassing to some patients and palpating the greater trochanter may be a better option
Symphysis pubis
86
SEVEN LANDMARKS OF THE ABDOMEN
-can be used to determine the lower margin on a PA abdomen with the patient in a prone position
-two bony prominences, which can be palpated most easily on thin patients, bear most of the weight of the trunk
when one is seated
-the lower margins of the ischial tuberosities are about 1 to 4 cm below or distal to the symphysis pubis
-may be used for positioning a PA projection of the colon when the rectal area is to be included on the IR

87
KINDS OF RESPIRATION TECHNIQUE
- taking in of air and holding it, then exposure is taken
Suspended Inhalation
88
KINDS OF RESPIRATION TECHNIQUE
- blowing out of air and then exposure is taken
Suspended Exhalation
89
KINDS OF RESPIRATION TECHNIQUE
- the patient is asked to take a deep breath and while holding the breath in, to bear down as though trying to move the bowels. This maneuver forces air against the closed glottis
Valsalva Maneuver
90
KINDS OF RESPIRATION TECHNIQUE
- accomplished as the patient pinches off the nose, closes the mouth and tries to blow the nose. The cheeks should expand outward as though the patient were blowing up a balloon.
Modified Valsalva Maneuver

KINDS OF RESPIRATION TECHNIQUE
- the patient exhales and then tries to inhale against a closed glottis
Mueller Maneuver
