ATI Oxygen Terms Flashcards
Apnea
Cessation of respiration
Atelectasis
occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid
Bi-level positive airway pressure(BiPAP)
a noninvasive, ventillation-assistance modality that provides higher airway pressure during inspiration and a lower pressure during expiration, usually delivered by a face mask
bradypnea
an abnormally slow respiratory rate, usually less than 12 respirations per minute
Carbon dioxide
an orderless, colorless gas resulting from the oxidation of carbon, formed in the tisues and eliminated by the lungs
Continous positive airway pressure (CPAP)
a noninvasive, ventilation-assistance modality that provides a set positive airway pressure throughout the patients respiratory cycle
Cyanosis
a bluish discoloration especially of the skin and mucous membranes due to excessive concentration of deoxhemoglobin (hemoglobin not combined with oxygen) in the blood
Dyspnea
difficult or labored breathing
Face Tent
a soft, oxygen-delivered mask that fits under the patients 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
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
Hypoexima
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
Intubation
the insertion of a tube into a body canal or cavity, as in endotracheal intubation
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)
nasal cannula
a common oxygen-delivery device consisting of a length of tubing with two small prongs that are inserted into the patient’s 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
nonrebreather mask
an oxygen-delivery apparatus used to deliver high flow rates and high concentrations of oxygen via a mask that fits snugly over the patient’s mouth and nose
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 oximetry
a noninvasive device that measures oxygen saturation indirectly via a finger or ear probe with a light-emitting diode (LED) and a photo detector attached by a cable to the device
simple face mask
an oxygen-delivery apparatus used for patients who require a moderate flow rate for a short period of time via a plastic mask that fits snugly over the mouth and nose
t-tube
a t-shaped conduit with a piece that connects an oxygen source to the patient’s artificial airway
tachypnea
abnormally rapid breathing
tidal volume
the amount of air normally breathed in and out with each respiratory cycle either spontaneously or delivered via mechanical ventilation
tracheostomy
an opening created by a surgical incision into the trachea for the purpose of establishing and maintaining an airway
tracheostomy collar
a small oxygen-delivery apparatus that fits over a tracheostomy site and is held in place by an adjustable elastic strap that fits around the patient’s neck; also called a tracheostomy mask
tracheostomy mask
a small oxygen-delivery apparatus that fits over a tracheostomy site and is held in place by an adjustable elastic strap that fits around the patient’s neck; also called a tracheostomy collar
ventilation
the process of the exchange of air between the lungs and the environment, including inhalation and exhalation`
venturi mask
an oxygen-delivery apparatus consisting of a mask with holes on each side that allow exhaled air to escape and color-coded entrainment ports that are adjustable to allow regulation of the concentration of oxygen delivered
