Mod 6 Flashcards
What is the function of the respiratory system?
Gas exchange
What function does the nose have in respirations?
warms, humidifies, and filters.
What function does the pharynx do in respirations?
supplied with tissue that traps and destroys pathogens entering with the air
What does the larynx do?
provides speech and maintains airway patency by closing the epiglottis during swallowing.
Trachea and bronchi does what?
trap pathogens and microscopic particulate
Cilia does what?
facilitate upward movement of foreign particles to the larynx and throat.
When does gas exchange occur?
only when air enters the bronchioles and alveol
What is respiratory membrane?
a single layer of cells covered by a network of pulmonary capillaries
gas exchange occurs where?
Respiratory membrane
What delivers low concentration of O2(24%-45%),at a flow rate of 2-6 LPM?
nasal cannula
What delivers 40%-60%oxgen, at a flow rate of 5-8 LPM?
simple mask
what delivers 40%-60% O2,at a flow rate of 6-10 LPM?
partial rebreather mask
what has the highest oxygen delivery at 95%-100% with a flow rate of 10-15 LPM?
non-rebreather mask
A Venturi mask delivers oxygen at what % and what flow rate?
24%-50% with a flow rate of 4-10 LMP
What delivers O2 at 30%-50%,with a flow rate of 4-8 LPM?
face tent
what is the purpose of an artificial airway?
to maintain a patent airway for obstructed airways or potential for obstruction
What type of artificial airways are used for the upper respiratory?
- oropharyngeal
* nasopharyngeal
What type of artificial airways are used for the lower respiratory?
- endotracheal tube
* tracheostomy
What are the clinical manifestations of Hypoxia?
- Rapid pulse
- Rapid shallow respirations and dyspnea
- Increased restlessness or light headaches
- Flaring of the nares
- Substernal or intercoastal retraction
- Cynosis
what is Cynosis?
blueish discoloration of the skin, nailbed and mucous membranes due to decreased hemoglobin-oxygen saturation
hyperventilation that accompanies metabolic acidosis in which the body try to compensate by blowing off carbon dioxide through deep rapid breathing is referred to as what kind of breathing?
Kussmaul’s breathing
rhythmic waxing and waning of respirations from deep breathing to very shallow breathing with periods of temporary apnea that is related to cardiac failure, increased intercrainial pressure, brain damage, or drug overdose is called what?
Cheyne-strokes
