1261-1281 Oxygenation Flashcards
How much oxygen concentration can a venturi masks deliver
24-40 or 50% at liter flows of 4-10L/min
What type of oxygen is dry
wall outlet systems and cylinders
When are face tents usually used
when the client doesnt like masks
What are some lifespan considerations for suctioning a ETT or tracheostomy for infants and children
have an assistant keep the patients hands out of the way and their head in the midline position
Which catheter tip may be more effective
open tipped
What are some oxygen devices that can be given to infants and children
oxygen hoods and tents
What is some home care considerations for suctioning a ETT or tracheostomy
encourage client to cough to clear airways first
instruct how to determine if suctioning is needed
instruct proper process for suctioning
stress the importance of adequate hydration bx it thins out secretions
What is another type of cannula
reservior nasal cannulas also called oxymizer oxygen conserving devices
What are some home care considerations for suctioning
to clean– suction boiling water then suction air until the tube is dry
if cleaned this way, catheters can be reused up to 24hrs
teach to wash hands to prevent infection
What is a consideration when comparing tracheostomys to the other artificial airways
they have a greater risk for infections
What is a special consideration for a partial rebreather mask and nonrebreather masks
the reservoir bag attached cannot deflate completely during inpiration
Do you need to supply a humidifier to 1-2L/min flows
no
What are some techniques to decrease the risk of developing suction complications
suction only when needed use sterile technique dont use saline instillations use hyperinflation and hyperventilation before and after suctioning use hyperoxygenation
What are some lifespan considerations for suctioning a ETT or tracheostomy for older adult
oral antiseptic rinses reduce the rate of infection
perform thorough lung assessment before and after to determine the effectiveness of the suctioning
What are the two types of Non-invasive positive pressure ventilation
BiPAP
CPAP
Nasopharyngeal airways should be what before inserting
lubricated with water soluble gel
How much oxygen concentration can a non-rebreather deliver
95-100% at liter flows of 10-15L/min
Why is 2L of O2 per NC usually the max delivered in emergency situations
bx a higher concentration could stop their respiratory drive
What does CPAP stand for
continous positive air pressure
What are the steps for using a wall outlet oxygen system
attach flow meter to wall outlet
fill humidifier then attach to flow meter (if needed)
attach prescribed oxygen tubing and delivery device to the humidifier
regulate the flow to prescribed level
What are the two types of cuffed trachs
low pressure cuffed
foam cuffed
What are the different type of suction catheters
open tipped
whisitle tipped
oral
How much oxygen concentration can a partial rebreather deliver
40-60% at liter flows of 6-10L/min
Which catheter tip causes less irritation
whistle tipped
What are Non-invasive positive pressure ventilation used the most for
obstructive sleep apnea (OSA)
What are some lifespan considerations for children for suctioning
use a catheter
What are some considerations with suctioning a trach tube
only suction on the way out, limit to 5 to 10 seconds
use sterile technique
What are oro and nasopharyngeal airways used for
keeping the upper airways open in patient who might have secretions or a tongue that causes onbstruction like comatose, sedated, or patients with altered LOC
What amount of oxygen can a cannula deliver
25-45% at flow rates of 2-6L/min
What needs to be added to a dry oxygen supply
a humidifier essentially for liter flows over 4L/min
What conditions require Non-invasive positive pressure ventilation
chronic/acute respiratory failure
pulmonary edema
COPD
obstructive sleep apnea
What are some oxygen therapy safety precautions
always smoke away from the oxygen supply
place cautionary no smoking signs near the oxygen supply
make sure electrical equipment is working to prevent sparks
avoid materials that generate static electricity
Avoid using volitile materials near the oxygen supply
Teach location of fire extinguishers
What are some safety precautions for cylinder oxygen
store away from heat and high traffic
secure to something
Whats the difference between CPAP and BiPap
BiPap has two pressure settings while CPAP doesnt
Why is humidification for reservior nasal cannulas not required
because the moisture from the patient exhaling is capture and then redelivered on the next inspiration
What are some nursing interventions for clients with endotracheal tubes
Assess clients respiratory status q2h
maintain a cuff pressure of 20-25 mmHg
provide a picture board or note pad for communication
provide oral and nasal care every 2-4hours
unless contraindicated, elevate bed to 30-45 degrees
Is humidification required for reservior nasal cannulas
no
What are the limitations of masks
finding the right size
poor tolerance of them by the client
What are some lifespan considerations for infants for suctioning
use a bulb syringe
When can the nurse administer oxygen tharapy
with an order from the PCP
during emergencies without a PCP order
What is a special consideration for venturi masks
they have multiple sizes for tubing which are typically color coded for a specific O2 concentration so make sure you have the right tube
How do you determine the correct size suction catheter for ETT (endotracheal tubes) or tracheostomys
double the millimeter size of the artificial airway being used. for example if a 8mm tracheostomy is used the max size catheter that should be used is size 16
What kind of patients usually get face tents
anesthesia patient s
How does CPAP and BiPap work
they keep the alveoli and airways open
Because oropharyngeal airways stimulate the gag reflex they are only used on who
patients with altered LOC like anesthesia, head injuries, and overdoses
What are some lifespan considerations for older adults for suctioning
watch for signs of hypoxemia, stop and hyperoxygenate if you see signs
What does some nursing care of trachs involve
cleaning and suctioning
What are the two types of tracheostomy’s
normal
cuffed
What is the advantage of cuffed trachs
their Airtight seal prevents aspiration and air leakage
Are humidifiers required for normal cannula
yes
What are the two types of reservior nasal cannulas
pendant style
mustashe style
What are the four most common artificial airways clients can have
oropharyngeal
nasopharyngeal
endotracheal
tracheostomy
What are the limitations of cannula
they cant deliver high concentrations of oxygen
they can dryout mucous membranes
What does FiO2 mean
fraction of inspired O2
How much oxygen concentration can a simple face mask deliver
40-60% at liter flows 5-8L/min
What does BiPap stand for
bilevel positive air pressure
What are the complications associated with suctioning endotracheal or tracheostomy tubes
hypoxemia
infection
cardiac dysrythmia
What fraction of O2 can a reservior nasal cannula deliver
0.5 or greater
What O2 concentration can face tents deliver
30-50% at liter flows of 4-8L/min
What type of schedule is suctioning usually on
as needed based on respiratory distress or inability to expectorate
