| chest x-ray | tumors, inflammation, air, fluid, chest tubes |
| pulmonary angiography | radiopaque dye thru catheter for pulmonary circulation, NPO, check allergies, avoid taking BP after |
| sputum study | culture and sensitivity, gram stain, acid fast bacillus. get in AM, sterile from suctioning or expectoration, NOT SALIVA |
| thoracentesis | intrapleural fluid, withdrawn to check for infection or empyema, local anesthesia only, done sitting at bedside |
| pulmonary function tests (PFTs) | non-invasive to measure lung volume, ventilation, diffusing capacity using sirometer. PT breathes thru spirometer, computer calculates the volumes. No smoke or bronchodilators b4 test |
| arterial blood gas (ABG) | checks arterial blood for tissue oxygenation, ventilation, acid base status. B4, document pt temperature and O2 and mech vent |
| lung scan (ventilation/perfusion scan) (V/Q scan) | visual inhalation or IV injection of radioisotopes to create an image of blood flow in the lungs. B4: PT must remove metal objects, they have to lie still for 1 hr during procedure |
| mantoux intradermal skin test | injection of tuberculin to detect TB antibiodies, document dermatitis or rashes, hx of positive test or vaccination for bacille Calmette Guerin, circle and record test side and date of follow up reading |
| laryngoscopy | directly visualize the larynx, NPO |
| lung biopsy | removal of lung tissue by open biopsy or endoscopye with need removes a core of lung tissue. NPO. after, assess resp checking for pneumothorax, air embolism hemoptysis, hemorrhage |
| blood chem | K, Na, Ca, phosporus, glucose, bicarb, BUN, creatinine, protein, albumin, osmolality, alph-antrypsin. NPO |
| hematologic | RBC, WBC, PT, INR, PTT, ESR, Hb, HCT. Note meds |
