what are early signs of hypoxia or respiratory insufficiency?
- -sits up to breathe
- -complains "I can't catch my breath"
- -Memory lapse
- -Mental dullness
what are intial signs of hypoxia or respiratory insufficiency?
- -blood pressure up
- -pulse up
- -respirations up
what are later signs of hypoxia or respiratory insufficiency?
- -blood pressure down
- -pulse down
- -use of accessory muscle
what is the latest signs of hypoxia or respiratory insufficiency?
- -muscle retraction
what is the flow of 1L of oxygen?
what is the flow of 2L of oxygen?
what is the flow of 3L of oxygen?
what is the flow of 4L of oxygen?
what is the flow of 5L of oxygen?
what is the flow of 6L of oxygen?
what is nasal cannula oxygen delivery?
low concentrations dependent on rate and depth of breathing
what are some advantages of a nasal cannula?
pt can move, talk, and eat without disrupting delivery of oxygen.
what is the simple mask oxygen delivery?
- -low to medium concentration
- - 40%-60%
- -must be use liter flow greater that 5L/min
what are some advantages of using the simple mask?
higher delivery of oxygen than with a cannula
what is the oxygen delivery of the partial rebreathing mask?
- -higher concentration
- - 60%-80%
- -must keep reservoir bag inflated at all times
what is some advantages of the partial rebreathing mask?
rebreathes 1/3 of exhaled breath that is high in oxygen.
what is the non-rebreathing mask oxygen delivery?
- -Highest concentration
- - 80%-95%
- - must keep reservior bag inflated
what is some advantages of the non-rebreathing
can deliver 80-90% of oxygen in emergency situation
what is the venturi mask oxygen delivery?
- -delivers consistent fio2; regardless of breathing pattern
- - 24%-50% masks available
what is the advantages of the venturi mask?
- -deliver consistent Fio2 regradless of breathing pattern
- -it is useful when accuracy of delivery is essential
when doing a focused assessment you must assess the respiration?
- (Rationale: although rate may be within normal limits; the patient may be breathing very shallowly and consequently not oxygenating well.)
what symptoms indicate the patient should be assessed for possible hypoxia?
- -restlessness and irritability
- -decreased ability to concentrate
- -lethargy (abnormal drowsiness)
- -cardiac arrhythmia
- (rational: these can all indicate that the patient is not obtaining enough oxygen)
how can you reverse slight hypoxia?
you can reverse slight hypoxia by turning, coughing, and deep breathing
where is the best place to check for cyanosis in dark skinned people?
inside the mouth
Deep rattling cough indicates ___________.
shallow raspy cough may indicate ____________.
sputum produce in the morning may indicate _________ rather than _________
sinus drainage, a problem in the lungs
what are factors that cause restriction of respiratory effort?
- -fractured ribs
- -server arthritis
- -many disease cause restrictive respiratory disorder
what is respiratory insufficiency?
is the inability of the body to meet its oxygen needs and remove excess amounts of carbon dioxide
what is the most common cause of respiratory insufficiency?
what is one of the first signs of hypoxia?
irritability or restlessness
what affects do hypoxia have on the body system?
hypoxia depresses body functions and disturbs the acid-base balance of the body.
collasped area of the lung
tube for insertion into a cavity or vessel
bluish color around the lips and of mucous membrane from lack of oxygen
cough up and spit out secretions
device that dispenses liquid in a fine spray
above-normal level of carbon dioxide in the blood
low level of oxygen in the blood
the condition of insufficent oxygen in the blood
curved guide for the tracheostomy tube
muscles move inward upon inspiration
shrill, harsh sound made when breathing is obstructed
condition of being without oxygen
device supplying moisture to air or oxygen
absence of breathing
the exchange of air between the lungs and the atmosphere
the exchange of oxygen and carbon dioxide between the atomosphere and the body cells
what structure controls respiration
CNS (central nervous system)
what structure helps move mucus and debris from the lungs?
what structure phagocytize inhaled bacteria and foreign objects?
what structure sense changes in oxygen or carbon dioxide and signal the brain stem?
what structure secrete mucus to assist cilia to cleanse respiratory tract of foreign particles?
what structure allows diffusion of oxygen and carbon dioxide from alveoli into the blood stream?
what structure transport air with oxygen to the lungs?
what structure warm and humidify air on its way to the lungs?
upper airway passage
what is some advantages of the tracheostomy collar?
adds humditiy to oxygen flow for a tracheostomy
what is some advantages of the t-bar?
adds humditiy to oxygen flow for a tracheostomy
list four saftey precautions to be observed when performing endotracheal suctioning?
- -preoxygenate the patient
- -maintain sterility of the suction catheter and supplies
- -be certain suction is turned on before inserting the catheter
- -do not suction for more then 10 seconds at a time
list four reasons an artificial airway may be used
- -to relieve an airway obstruction
- -to protect the airway
- -to facilitate suctioning
- -to provide artifical ventilation
what are the steps when assessing respiratory status?
- -asculate lungs
- -take vital signs
- -check skin and mucous membranes color
