1. Hypercapnia
    Elevated arterial PaCO2 greater than 45 mm Hg; also called hypercarbia. (Potter 1221)
  2. Hypoxemia
    Abnormal deficiency of oxygen in arterial blood. (Potter 1221)
  3. Hypoxia
    Insufficient oxygen available to meet the metabolic needs of tissues and cells. (Potter 1221)
  4. Incentive spirometry
    Method of deep breathing providing visual feedback to patients concerning their inspiratory volume. (Potter 1221)
  5. Nasal cannula
    Device for delivering oxygen by way of two small tubes that are inserted into the nares. (Potter 1222-1223)
  6. Noninvasive ventilation
    "Noninvasive ventilation (NIV) maintains positive airway pressure and improves alveolar ventilation without the need for an artificial airway. In addition, this mechanical ventilator alternative reduces and reverses atelectasis, improves oxygenation, reduces pulmonary edema, and improves cardiac function. (Potter 1223)"
  7. Oxygen mask
    A flexible mask that fits snugly and securely over a patient's nose and mouth for delivery of oxygen. (Potter 1223)
  8. Oxygen therapy
    Administration of oxygen by any route to a patient to prevent or relieve hypoxia. (Potter 1223)
  9. Positive-pressure ventilation
    Mechanical ventilation that delivers compressed gas to the airways at greater than ambient pressure. (Potter 1224)
  10. T tube
    A T-shaped device that is attached to an endotracheal or tracheostomy tube for delivery of humidified air. (Potter 1226)
  11. Tidal volume
    "Amount, in milliliters, of air inhaled with each breath. Spontaneous tidal volume is 5 to 10 mL/kg body weight. (Potter 1227)"
  12. Tracheostomy collar
    Curved oxygen delivery device with an adjustable neck strap that fits around the tracheostomy. (Potter 1227)
