| A | B |
| apnea | absence of breathing |
| arterial blood gas | laboratory test using blood from an artery, checks pH of blood |
| CPAP mask | device that maintains positive pressure in the airway throughout the respiratory cycle |
| diaphragmatic breathing | breathing that promotes the use of the diaphragm rather than upper chest muscles |
| expiration | exhalation, breathing out |
| face tent | device that provides oxygen in an area around the nose and mouth |
| flowmeter | gauge used to regulate the number of liters of oxygen delivered to the client |
| Fowler's position | upright seated position |
| fraction of inspired oxygen | portion of oxygen in relation to total inspired gas |
| humidifier | device that produces small water droplets |
| hyperbaric oxygen therapy | delivery of 100 percent oxygen at 3 times the normal atmospheric pressure in an airtight chamber |
| hypercarbia | excessive levels of carbon dioxide in the blood |
| hypoxemia | insufficient oxygen in arterial blood |
| hypoxia | inadequate oxygen at the cellular level |
| incentive spirometry | technique for deep breathing using a calibrated device |
| inspiration | inhalation; breathing in |
| liquid oxygen unit | device that converts cooled liquid oxygen to a gas by passing it through heated coils |
| nasal cannula | hollow tube with prongs that are placed into the client's nostrils for delivering oxygen |
| nasal catheter | tube for delivering oxygen that is inserted through the nose into the posterior nasal pharynx |
| nonrebreather mask | oxygen delivery device in which all the exhaled air leaves the mask rather than partially entering the reservoir bag |
| orthopneic position | seated position with the arms supported on pillows or the arm rests of a chair |
| oxygen therapy | therapeutic intervention for administering more oxygen than exists in the atmosphere |
| oxygen toxicity | lung damage that develops when oxygen concentrations of more than 50 percent are administered for longer than 48 to 72 hours |
| partial rebreather mask | oxygen delivery device through which a client inhales a mixture of atmospheric air, oxygen from its source, and oxygen contained in a reservoir bag |
| pulse oximetry | noninvasive, transcutaneous technique for periodically or continually monitoring the oxygen saturation of blood |
| pursed-lip breathing | form of controlled ventilation in which the expiration phase of breathing is consciously prolonged |
| respiration | exchange of oxygen and carbon dioxide |
| simple mask | device for administering oxygen that fits over the nose and mouth |
| stent | tube that keeps a channel open |
| surfactant | lipoprotein produced by cells in the alveoli that promotes elasticity of the lungs and enhances gas diffusion |
| tension pneumothorax | extreme air pressure in the lung when there is no avenue for its escape |
| tidaling | rhythmic rise and fall of water in a chest tube drainage system |
| T-piece | device that fits securely onto a tracheostomy tube or endotracheal tube |
| tracheostomy collar | device that delivers oxygen near an artificial opening in the neck |
| transtracheal catheter | hollow tube inserted into the trachea to deliver oxygen |
| ventilation | movement of air in and out of the lungs |
| Venturi mask | oxygen delivery device that mixes a precise amount of oxygen and atmospheric air |
| water-seal chest tube drainage | techniques for evacuating air or blood from the pleural cavity |
