Q

A method of ventilation used to treat critically ill patients with respiratory distress; can prevent need for endotracheal intubation.

A

continuous positive airway pressure (CPAP)

22
Q

The portion of the tidal volume that does not reach the alveoli and thus does not participate in gas exchange.

A

dead space

23
Q

A process in which molecules move from an area of higher concentration to an area of lower concentration.

A

diffusion

24
Q

The active, muscular part of breathing that draws air into the airway and lungs.

A

inhalation

25
Q

The exchange of gases between the blood cells and the tissues.

A

internal respiration

26
Q

The passive part of the breathing process in which the diaphragm and the intercostal muscles relax, forcing air out of the lungs.

A

exhalation

27
Q

The exchange of gases between the lungs and the blood cells in the pulmonary capillaries; also called pulmonary respiration.

A

external respiration

28
Q

A normal reflex mechanism that causes retching; activated by touching the soft palate or back of the throat.

A

gag reflex

29
Q

A condition in which air fills the stomach, often as a result of high volume and pressure during artificial ventilation.

A

gastric distension

30
Q

The space in between the vocal cords that is the narrowest portion of the adult’s airway; also called the glottic opening

A

glottis

31
Q

A term used to distinguish the degree of distress in a patient with a mild airway obstruction. The patient is conscious and can cough forcibly, although wheezing may be heard.

A

good air exchange

32
Q

A combination of two movements to open the airway by tilting the forehead back and lifting the chin; not used for trauma patients

A

head tilt-chin lift maneuver

33
Q

A partial or complete accumulation of air in the pleural space.

35
Q

The process of exchanging oxygen and carbon dioxide.

Q

Bypassing of oxygen poor blood past nonfunctional alveoli to the left side of the heart.

A

Q

Technique to open the airway by placing the fingers behind the angle of the jaw bringing the jaw forward; used for patients who may have a cervical spine injury.

A

jaw-thrust maneuver

40
Q

Breathing that requires greater than normal effort; may be faster or slower than normal and usually requires the use of accessory muscles.

A

labored breathing

41
Q

A complex structure formed by many independent cartilaginous structures that all work together; where the upper airway ends and the lower airway begins; also called the voice box.

A

larynx

42
Q

A fixed flow rate ventilation device that delivers a breadth every time its button is pushed; also referred to as a flow-restricted, oxygen-powered ventilation device.

A

manually triggered ventilation device

43
Q

Space within the chest that contains the heart, major blood vessels, vans nerve, trachea, major bronchi, and esophagus; located between two lungs.

A

mediastinum

44
Q

Occurs when a foreign body partially obstructs the patient’s airway.

A

mild airway obstruction

45
Q

The volume of air moved through the lungs in 1 minute; calculated by multiplying tidal volume and respiratory rate; also called minute ventilation.

A

minute volume

46
Q

An oxygen-delivery device in which oxygen flows through two small, tubelike prongs, that fit into the patient’s nostril; delivers 24% to 44% supplemental oxygen, depending on flow rate.

A

nasal cannula

47
Q

Airway adjunct inserted into the nostril of an unresponsive patient or patient with LOC who cannot maintain airway independently

A

nasopharyngeal (nasal) airway

48
Q

A combination mask and reservoir bag system preferred in hospital to supply oxygen in a prehospital setting; delivers 90% inspired oxygen and prevents inhaling the exhaled gases.

A

nonrebreathing mask

49
Q

Airway adjunct inserted into the mouth of an unresponsive patient to keep the tongue from blocking the airway and to facilitate suctioning the airway, if necessary.

A

oropharyngeal (oral) airway

50
Q

A system established for portable cylinders to ensure that a regulator is not connected to a cylinder containing the wrong type of gas.

A

pin-indexing system

51
Q

A degree of distress in a patient with a mild airway obstruction. The patient has weak, ineffective cough, increased difficulty of breathing, or possible cyanosis and may produce a high-pitched noise during inhalation (stridor).

A

poor air exchange
