| Question | Answer |
|---|---|
| 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 |
