what is the appropriate Levels to administer O2 Therapy ?
1.Adult= 30-60%(40-55% is better)-if pt. not COPD never start on <30% (40% is better). 2.Emergency-100% 3.COPD pts.=24-30%. 4.if a choice is given start with lower FIO2. O2 is a drug&should be kept @ lowest possible dose (if PaO2 =110mmHg, LOWER FIO2/PEEP
What is the special consideration for COPD pts. With O2 Therapy?
1. High PaO2 - causes Hypoventilation. 2. Decrease RR & Vt. 3. Lower O2 to treat. 4. Permit hypoxemia (PaO2-50-65 mmHg is ok) 5. It is described as stuporous (indicates excessive CO2).
What is a Titration UP in O2 Thearpy?
1.Increases FIO2 (if Hypoxic)-10% until @ 60% 2.Once @ 60% need to add PEEP(If on vent.)/CPAP/BIPAP. 3. Keep adding PEEP in 5cm H20 until a desire PaO2 is obtained/until you witness -ve cardiac response. 4.If PEEP @ its limit then increase FIO2 above 60%
O2 hazards- what are the O2 toxicity signs?
1. Tachypnea. 2. Refractory hypoxemia - a fix hypoxemia w/PEEP/CPAP not FIO2. 3. Decreases compliance - decreased surfactant in the lungs. 4. Pulmonary lungs and 5. Nausea.
In O2 Therapy when do you apply Visual/ Bedside signs
1. Caused by rapid changes in FIO2. 2. Alveoli collapse as a result of changing FIO2 too quickly. 3. Prevent by making small changes in FIO2(10%/less @ a time.)
What are the hazards of O2 Therapy?
1. O2 toxicity. 2. Absorption atelectasis.
What are the saftey consideration for O2 Hazards?
1. No smoking. 2. Post O2 in use sign. 3. Instruct pt. and family members of the rules and dangers. 4. No electrical devices.
What are the O2 mixtures & therapies in O2 Therapy - HeliOx
1. Used for Lower airway resistance. 2. He molecules are apart & easier to breath when comparing w/Nitrogen(N). 3. He replaces N but must be combined w/O2. 4.Decreases WOB. 5. Good for pts. w/upper airway obstruction & inflammation. 6.Given w/ a NBR mask
In What situations does Hyperbaric O2 therapy is used ?
1. CO poisioning. 2. Decompression sickness. 3. Help wounds to heal more quickly. 4. Assist tissue grafts.
