Finals - Oxygenation Therapy - Sheet1 Flashcards
Normal oxygen saturation
95% - 100%
Normal respiration rate
12 - 20 cycles per minute
PaO2 indicator = 80 -100 mm Hg
Normal
PaO2 indicator = 60 -80 mm Hg
cold, clammy extremities
PaO2 indicator = <60 mm Hg
cyanosis
PaO2 indicator = <40 mm Hg
mental deficiency and memory loss
PaO2 indicator = <30 mm Hg
bradycardia and cardiac arrest
How much PaO2 would be considered for oxygen therapy?
PaO2 < 60 mm Hg
measures the balance of oxygen and carbon dioxide in your blood to see how well your lungs are working.
Arterial Blood Gas
nursing diagnosis for difficulty breathing
Impaired Gas Exchange
Ineffective Breathing Pattern
Ineefective Airway Clearance
nursing interventions for difficulty breathing
position patient in semi-Fowler’s, or high Fowler’s as tolerated
position patient in orthopneic position
tripod position
is a colorless, odorless, tasteless gas that is essential for the body to function properly and to survive.
Oxygen
is the administration of oxygen at a concentration of pressure greater than that found in the environmental atmosphere
Oxygen therapy
The air that we breathe contain approximately ___% oxygen.
21%
Examples of situations where oxygen therapy is needed
Documented hypoxemia
Severe Respiratory Distress (acute asthma, pneumonia)
Severe trauma
COPD
Pulmonary hyoertension
Acute myocordial infarction
Post-anesthesia Recovery
this shows the amount of oxygen in the tank.
.
A reduction gauge
this regulates the control of oxygen in liters per minutes.
A flow meter
Oxygen is moistened by passing it through a ___ to prevent the mucous membranes of the respiratory tree from becoming dry
humidifier
2 types of oxygen dispensers
oxygen tank
wall-outlet oxygen
Oxygen Delivery Systems:
- Nasal Cannula
- Simple Mask
- Partial Re-Breather Mask
- Non-Re Breather Mask (NRBM) Venturi Mask
- Oxygen Hood
- Oxygen Tent
- AMBU Bag
- Tracheostomy Collar,
- T-piece
It is a disposable, plastic devise with two protruding prongs for insertion into the nostrils, connected to an oxygen source.
Used for low-medium concentrations of Oxygen (24-44%).
Nasal cannula (prongs):
It delivers 35% to 60% oxygen.
A flow rate of 6 to 10 liters per minute.
It has vents on its sides which allow ro air to leak in at many places, thereby diluting the source oxygen.
>
Often it is used when an increased delivery of oxygen is needed for short periods (ie., less than 12 hours).
The simple Oxygen mask
Nursing Responsibilities to Client with Nasal
Cannula
- Check frequently that both prongs are in client’s nasal nares
- Never deliver more than 2-3 L/min to patients with chronic
lung disease, especially if patient does not need it.
Nursing Responsibilities to Client with Simple
Face Mask
- Monitor client frequently to check placement of the mask.
- Support client if claustrophobia
is his concern. - Secure physician’s order to replace mask with nasal
cannula during meal time.
is designed to get
hold of the first 150ml of
the breath that has been
exhaled into the
reservoir bag so that it
can be used for
inhalation in the next
subsequent breath.
A Partial re-breather
mask
Nursing Responsibilities to Client with Partial
Rebreathing Masks
Set flow rate so mask remains two- thirds full during inspiration
>Keep reservoir bag free of twists or kinks
Prevents the reservoir bag to collapse or be empty
Prevents anyone to squeeze the bag while on the patient.
It is high flow oxygen delivery device.
> Oxygen from 40-50% At liters flow of 4 to 15 L/min.
The mask is constructed so that there is a constant flow of room air blended with a fixed concentration of oxygen
Venturi Mask
this is used for babies who can breathe on their own but still need extra
oxygen.
A hood is a plastic dome or box with warm, moist oxygen inside.
The hood is placed over the baby’s head
Oxygen Hood
this consists of a canopy placed
over the head and shoulders, or over the entire body of a patient to provide oxygen at a higher level than normal.
Oxygen Tent
Inserted directed into trachea
Is indicated for chronic 02 therapy need
02 flow rate 8 to 10L
Provides accurate FIO2
Provides good humidity.
Comfortable,more efficient
Tracheostomy Collar/Mask
is a hand-held device
commonly used to provide positive pressure
ventilation to patients who are not breathing
or not breathing adequately.
AMBU-Artificial Manual Breathing Unit (or)
Valve Mask Ventilation
It is a condition which occurs due to inspiration of a high concentration of oxygen for aprolonged period of time.
Oxygen Toxicity
Oxygen concentration greater than 50% over 24 to 48 hours can cause pathological changes in the lungs.
NA
Blindness due to vasoconstriction &
Ischemia (premature infants)
Retrolental fibroplasia
when not enough gas is left in the alveoli to maintain patency, and the alveolus collapses; this is known as
absorption atelectasis
