Chapter 8: Respiratory System
Learning Tip Sing content you need to remember, like these tests and procedures, using sim- ple, easily remembered tunes such as “Happy Birthday to You” or nursery songs. Add movements as you sing to engage your kinesthetic sense. The sillier the song, the easier it is to remember. Video yourself and share it with your classmates to help them remember too!
pleurodesis: Infusion of a sterile, irritating substance into the pleural space, causing the pleural linings to fuse to one another by developing scar tissue. postural drainage: Placement of the patient in various positions that facilitate drainage of secretions from the lungs, often done along with chest physio- therapy (CPT). pulmonary angiography: Radiographic examination of pulmonary circula- tion after injection of a contrast dye. pulmonary function tests (PFTs): Group of tests that provide information regarding lung capacity; sometimes called spirometry (Figure 8-7). pulse oximetry: Indirect measurement of the saturation of peripheral oxygen (SpO 2 ) to help determine if sufficient oxygen is being delivered to the body. The normal level in a person with healthy lungs is 96% to 99%. sputum analysis: Examination of mucus or fluid coughed up from the lungs. thoracentesis: Surgical puncture of the chest wall to remove fluid from the interpleural space; also called pleurocentesis (Figure 8-8). vital capacity (VC): Measurement of the volume of air that can be exhaled after maximum inspiration.
