Title: Oxygen Therapy


1
Oxygen Therapy
  • Terri Slifer Lynch, MSN, RN, BC
  • Fall, 2006

2
Factors Influencing Oxygen Transport
  • Cardiac output
  • Arterial oxygen content
  • Concentration of Hgb
  • Metabolic requirements

3
  • Hypoxemia decrease in the arterial oxygen
    content in the blood
  • Hypoxia decreased oxygen supply to the tissues.

4
Clinical Manifestations of Hypoxia
  • Impaired judgment, agitation, disorientation,
    confusion, lethargy, coma
  • Dyspnea
  • Tachypnea
  • Tachycardia, dysrhythmias
  • Elevated BP
  • Diaphoresis
  • Central cyanosis

5
Need For Oxygen Is Assessed By
  • Clinical evaluation
  • Pulse oximetry
  • ABGs

6
Cautions For Oxygen Therapy
  • Oxygen toxicity can occur with FIO2 gt 50
    longer than 48 hrs
  • Suppression of ventilation will lead to
    increased CO2 and carbon dioxide narcosis
  • Danger of fire
  • Infection

7
Methods of Dispensing Oxygen
  • Piped in
  • Cylinder
  • Oxygen concentrator

8
Classification of Oxygen Delivery Systems
  • Low flow systems
  • contribute partially to inspired gas client
    breathes
  • do not provide constant FIO2
  • Ex nasal cannula simple mask
  • High flow systems
  • deliver specific and constant percent of oxygen
    independent of clients breathing
  • Ex Venturi mask, non-rebreather mask

9
Nasal Cannula
  • Used for low-medium concentrations of O2
  • Simple
  • Can use continuously with meals and activity
  • Flow rates in excess of 4L cause drying and
    irritation
  • Depth and rate of breathing affect amount of O2
    reaching lungs

10
Simple Mask
  • Low to medium concentration of O2
  • Client exhales through ports on sides of mask
  • Should not be used for controlled O2 levels
  • O2 flow rate- 6 to 8L
  • Can cause skin breakdown must remove to eat

11
Partial Rebreather Mask
  • Consists of mask with exhalation ports and
    reservoir bag
  • Reservoir bag must remain inflated
  • O2 flow rate - 8 to 10L
  • Client can inhale gas from mask, bag, exhalation
    ports
  • Poorly fitting must remove to eat

12
Non-rebreather Mask
  • Consists of mask, reservoir bag, 2 one-way valves
    at exhalation ports and bag
  • Client can only inhale from reservoir bag
  • Bag must remain inflated at all times
  • O2 flow rate- 10 to 15L
  • Poorly fitting must remove to eat

13
Venturi Mask
  • Most reliable and accurate method for delivering
    a precise O2 concentration
  • Consists of a mask with a jet
  • Excess gas leaves by exhalation ports
  • O2 flow rate- 4 to 15L
  • Can cause skin breakdown must remove to eat

14
Tracheostomy Collar/ Mask
  • O2 flow rate 8 to 10L
  • Provides accurate FIO2
  • Provides good humidity comfortable

15
T-piece
  • Used on end of ET tube when weaning from
    ventilator
  • Provides accurate FIO2
  • Provides good humidity

16
Pulse Oximetry
  • Non-invasive monitoring technique that estimates
    the oxygen saturation of Hgb (SaO2)
  • May be used continuously or intermittently
  • Must correlate values with physical assessment
    findings
  • Normal SaO2 values 95 to 100

19
Factors Affecting SaO2 Measurements
  • Low perfusion states
  • Motion artifact
  • Nail polish when using a finger probe
  • Intravascular dyes
  • Vasoconstrictor medications
  • Abnormal Hgb
  • Too much light exposure

20
Nursing Interventions Related to Pulse Oximetry
Monitoring
  • Determine if strength of signal is adequate
  • Notify RN/physician if SaO2 , 90-92 or outside
    specific ordered limits
  • Evaluate sensor site every 8 hrs and move PRN to
    prevent loss of vascular flow or skin breakdown
  • Document SaO2, O2 requirements, clients activity
    according to policy

21
Purpose of Peak Flow Monitoring
  • Measures peak expiratory flow rate (PEFR) point
    of highest flow during maximal exhalation
  • Provides objective data to assess respiratory
    function
  • Allows better control of asthma

23
Procedure To Use Peak Flow Meter
  • Have client sit in Fowlers position or stand
  • Move blue/red indicator to bottom of scale
  • Instruct client to inhale as deeply as possible
    and place mouth firmly around mouthpiece
  • Client should exhale as hard and fast as possible
  • Slide the indicator back to the base of the scale
    and repeat 2 more times

24
  • Record the clients best effort
  • Determine clients zone
  • Green zone- 80-100 personal best
  • Yellow zone- 50-80 personal best
  • Red zone- less than 50 personal best
  • Encourage client to perform monitoring twice
    daily, before and after bronchodilators
  • Clean mouthpiece with soap and water and air dry

25
Metered Dose Inhaler
  • A pressurized device containing an aerosolized
    powder of medication
  • A spacer enhances the deposit of medication into
    the lungs

26
Instructions For Use Of MDI
  • Shake the inhaler canister well
  • When opening a new canister, expel the first puff
    into air
  • Exhale slowly and place inhaler 1-2in from mouth

27
  • If using spacer, place lips on mouthpiece
  • Press down on inhaler as start to breathe in
  • Hold breath for 3-5 seconds

28
  • When multiple puffs ordered, wait 1-2 minutes
    between puffs
  • If using more than one type of drug, administer
    quick acting bronchodilator first, then slower
    acting
  • Administer steroid last and rinse mouth with
    water
  • Clean spacer with soap and water and air dry

Hand Held Nebulizer (HHN)
  • Method of administering medication that has been
    aerosolized into a fine mist
  • With bronchodilators, pulse, respiratory rate,
    breath sounds are assessed before and after
    treatment

31

32
Procedure For Use of HHN
  • Assemble nebulizer and place proper med dose and
    diluent into neb cap using sterile technique
  • Have client sit in comfortable Fowlers position
  • Set source of gas flow to 6-8 LPM
  • Instruct client to place mouthpiece in mouth and
    slowly inhale

33
  • Have client hold breath for a few seconds and
    slowly exhale
  • Encourage client to cough during and after
    treatment
  • Mouthpieces and nebs are changed every three days
    or as policy guides
  • At home, follow manufactures directions to clean
