Ch. 11 Flashcards
A patient who is suspected of being hypoxic and is breathing adequately should be given supplemental oxygen with a
non-rebreathing mask
At a flow rate of 6 L/min., a nasal cannula can deliver an approximate oxygen concentration of up to
44%
Gas exchange in the lungs is facilitated by
adequate amounts of surfactant
Irregular respirations characterized by an increasing rate and depth of breathing followed by periods of apnea are called
Cheyne-Stokes respirations
Structures of the lower airway include all of the following except
the epiglottis
The hypoxic drive is influenced by
low blood oxygen levels
The presence of elevated carbon dioxide levels in the blood is called
hypercarbia
The pressure of gas in a full cylinder of oxygen is approximately ______ pounds per square inch (psi).
2,000
What is the most common cause of airway construction in an unconscious patient?
the tongue
What factor will cause a reduction in minute volume in an adult?
shallow breathing
What is a late sign of hypoxia?
cyanosis
What organ or tissue can survive the longest without oxygen?
muscle
Describe a patient who is breathing adequately.
A conscious person with respirations of 19 breaths/min and pink skin
Which of the follow structures is not found in the upper airway?
Larynx
Pharynx
Bronchus
Oropharynx
Bronchus
With a good mask-to-face seal and an oxygen flow rate of 15 L/min, the non-rebreathing mask is capable of delivering up to _____% inspired oxygen.
90
