Oxygen Therapy Testout PPT Flashcards
Respiratory rate NB Infant Toddler Child Adolescent Adult
NB: 30-60 Infant (6mo): 30-50 Toddler (2 yr): 25-32 Child: 20-30 Adolescent: 16-20 Adult: 12-20
Respiratory assessment
5 types
Rate Rhythm Effort Depth Odor
Respiratory assessment- factors that influence respiration
6 influences
Exercise Fever Acute pain Anxiety Smoking Body position
what influence make the rate and depth of respiration increase?
Exercise and Anxiety
what influence makes the rate of respiration increase?
Fever and Smoking
What influence makes the respiratory rate go up and the depth go down?
Acute pain
what influence makes the respiratory rate go down?
Body position
How does medication affect respiratory rate? Opioids? Amphetamines and cocaine? Bronchodilators? Caffeine?
Opioids: depress rate and depth
Amphetamines and cocaine: increased rate and depth
Bronchodilators: slow rate
Caffeine: shallow rapid breathing
Respiratory assessment for neurological injury?
Brain stem impairs respiratory center inhibiting rate and rhythm
Respiratory assessment for abnormal blood cell function?
Sickle cell disease
Increases respiratory rate and depth
What is Hypoxia?
Inadequate tissue oxygenation at the cellular level
Life threatening condition
Untreated produces cardiac dysrhythmias
Death
Clinical signs of Hypoxia
Increased pulse initially Increased resp rate and depth initially Cyanosis, later sign Apprehension Restlessness, can't lay flat Inability to concentrate Confusion Dizziness Behavioral changes Decreased LOC
Lung sounds common errors to avoid
listening to sounds through patients gown/clothing
tube rubbing against bed rails/clothing
chest hair
auscultating on only the convenient areas of the chest
Pulse oximeter sensor locations?
Bridge of adult nose Sole of infant foot Ear lobe Finger Toes Forehead Normal: 95-100%
Pulse ox interference
Nail polish Artificial nails Patient movement Jaundice Dark skin pigment Cold extremities
Types of inhalers and when taken Controller med? Combination inhaler? Anticholinergics? Rescue med?
Controller med: taken daily, corticosteroids
Combination inhalers: taken daily, contain inhaled corticosteroid plus long acting beta agonist
Anticholinergics: maintenance therapy, helps open airways
Rescue med: short acting beta agonists; quickly relax/open airways, used during flare or before exercise
Oxygen safety?
Start/adjust per Dr orders
Place “oxygen in use” sign
No smoking
Store cylinders upright in holders
Check O2 level prior to transferring patient
Monitor electrical equipment for integrity/ground plugs
Avoid petroleum and aerosol products containing acetone
Nasal Cannula percentage and Liters
1 Liter- 24% to 6 Liter- 44%
Max 6 liters
Simple mask % and liters
6-12 Liters
35-50% FiO2
Humidified
Venturi Mask % and liters
4 Liters: 24-28%
8 Liters: 35-40%
12 Liters: 50%
NonRebreather Mask % and liters
10-15 Liters: 60-90%
Bag must be inflated at all times
Simple Mask
Advantage?
Disadvantages?
Advantage:
humidifies O2
Disadvantage: O2 level difficult to estimate requires high flow O2 to prevent CO2 rebreathing hot/confining interferes with easting/drinking/talking condensation can irritate skin
Nasal Cannula
Advantages?
Disadvantages?
Advantage
most comfortable
can eat/drink/talk
can continue activity
Disadvantage: easily dislodged drying to mucous membranes can't use with nasal obstruction can't use with mouth breathing can cause skin irritation (monitor ears, nares, cheeks)
Venturi Mask
Advantages?
Disadvantage?
Advantage:
specific oxygen setting (COPD pt)
exhaled ports keep CO2 build up to min
Disadvantage: specific O2 flow needed to delivered specific O2 concentration hot/confining interferes with easting/drinking/talking condensation can irritate skin
NonRebreather Mask
Advantages?
Disadvantages?
Advantages:
highest noninvasive O2 delivery
respiratory distress
extubated ventilator pt
Disadvantage: reservoir bag must stay inflated hot/confining interferes with easting/drinking/talking condensation can irritate skin
