Chapter three final

Chest/thorax upper portion of truck between neck and abdomen-bony thorax, respiratory system and mediastinum
bony of thorax Clavicle, sternum, scapula ribs and thoracic vertebra
Respiratory System pharynx, trachea, bronchi and lungs
pharynx upper airway, between nose and mouth,passage way for fluid air and food
esophagus connects pharynx to stomach
respiratory system larynx, trachea, right and left bronchi and lungs
Larynx voice box suspended from hyoid bone
Trachea windpipe, in front of esophagus C6-T5 location of thymus, parathyroid and thyroid glands
Right Bronchi wider and shorter more vertical less of deviance food usually goes down this side divided to three bronchi
Left Bronchi smaller, more of an angle divided into two bronchi
Lungs right-3 parts left-2 parts contained in pleura inner pulmonary/visceral and partial on outside carina where two lung(bronchi) seperate
Hilum where bronchi, blood vessels lymph vessels and nerves leave the lung on right side of lung
mediastinum thymus gland, great heart vessels, trachea and esphagus
Hypersthenic broad deep thorax
stenic average
Hyposthenic thin long lungs
asthenic slender narrow and shallow
kV in chest low contrast long-scale contrast long scales of grey
mV i chest high mA and short exposure time
Pediatric chest lower kV (60-70) less mAs required usually can do supine
Geriatric patients less inhalation=higher CR location
why erect chest allow full inhilation, fluid goes to base of lungs
why 72 SID reduced magnification on heart shadows
PA chest patient chest to IR no rotation, alignment even spaced clavicles shoulder rolled forward arms up CR at T7 110 kV 4 mAs 72 inches
Lateral Chest left side to IR arms up, rule of thumb kV 125 mV 6 CR and midsagittal T7
AP chest supine 110 kV 1.7 mV at 40 SID 4 inches under JN
Aspiration swallowed foreign object-can see it
Atelectasis collapsed lung region appears more radiodense
Bronchiectasis irreversible dilation of bronchi-increase radiodensity in these areas
Bronchitis excessive mucus secretion into bronchi lower lobes hyperinflation and more dominant lung markings
COPD Chronic Obstructive Pulmonary disease persistent obstruction in airway same as emphysema
Cystic fibrosis heavy mucus secretion increased radiodensity in those lung areas
