ATI: Oxygen Therapy Questions
and Correct Answers
atelectasis
✓✓~ airlessness or collapse of a lung, usually as a result of hypoventilation or obstruction
bi-level positive airway pressure (BiPAP)
✓✓~ a noninvasive, ventilation-assistance modality that provides higher airway pressure during
inspiration and lower pressure during expiration, usually delivered by a face mask
continuous positive airway pressure (CPAP)
✓✓~ a noninvasive, ventilation-assistance modality that provides a set positive airway pressure
throughout the patient's respiratory cycle
cyanosis
✓✓~ a bluish discoloration, especially of the skin and mucous membranes, due to excessive
concentration of deoxyhemoglobin (hemoglobin not combined with oxygen) in the blood
dyspnea
✓✓~ difficult or labored breathing
face tent
, ✓✓~ a soft, oxygen-delivery mask that fits under the patient's chin, loosely covers the mouth and
nose, and is held in place by an adjustable elastic strap
flow meter
✓✓~ a device used to control the rate of oxygen being delivered in liters per minute
flow rate
✓✓~ the quantity of oxygen delivered in liters per minute
fraction of inspired oxygen (FiO2)
✓✓~ the oxygen level inhaled by or delivered to the patient, expressed in a percentage of
atmospheric air
hypercapnia
✓✓~ an excess of carbon dioxide in the blood
hypoxemia
✓✓~ a diminished amount (reduced saturation) of oxygen in arterial blood
hypoxia
✓✓~ a reduced supply of oxygen to tissues below physiological levels despite adequate perfusion
of the tissue by blood
incentive spirometer
, ✓✓~ a resistive breathing device that helps patients exercise their breathing muscles, provides
visual reference for deep breathing; educate patient:
1. exhale normally
2. place spirometer in mouth
3. inhale as deeply as possible through mouth & hold breath to count of 3
4. remove mouth from spirometer and exhale normally
5. perform 10x/ hour
manual resuscitation bag
✓✓~ a hand-held device consisting of a flexible air chamber attached to a face mask via a shutter
valve and used to provide ventilation to a patient who is not breathing or who is breathing
inadequately; often referred to by the common brand name, Ambu bag
mechanical ventilator
✓✓~ breathing assistance provided by a ventilator, one of various types of devices that support
and maintain respiratory function
naris
✓✓~ one of the two external orifices of the nose; nostril (plural: nares)
noninvasive ventilation
✓✓~ a type of breathing assistance used to maintain positive airway pressure and improve
alveolar ventilation without the need for an artificial airway
, oxygen
✓✓~ a tasteless, odorless gas that comprises 21% of atmospheric air and is used by the body to
maintain adequate cellular function
oxygen mask
✓✓~ a device that fits over the patient's nose and mouth and delivers oxygen, humidity, and/or
heated humidity
oxygen tent
✓✓~ a canopy that surrounds the patient, providing oxygen, humidification, and a cool
environment to help control body temperature
oxygen therapy
✓✓~ the delivery of oxygen for therapeutic purposes
partial nonrebreather mask
✓✓~ an oxygen-delivery apparatus similar to a nonrebreather mask, but with a two-way valve
allowing the patient to rebreathe exhaled air
positive-pressure ventilation
✓✓~ a technique that uses a mechanism such as a mechanical ventilator to force air into the
lungs to provide breathing assistance
pulse oximeter
