Answer: when a PaO2 is below 80mmHg (Adult) - unless COPD Question: In O2 Therapy when do you apply Visual/ Bedside Answer: 1. Cyanosis 2. Tachycardia 3. Confusion 4. 5. Low O2 Saturation (Pulse Oximetry needed) 6. Lethargic/ Sleepy Question: what is the appropriate Levels to O2 Therapy ? Answer: 1.Adult= 30-60%(40-55% is )-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 Question: What is a Titration UP in O2 ? Answer: 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 /until you witness -ve cardiac response. 4.If PEEP @ its limit then increase FIO2 above 60% Question: What is DOWN in O2 Therapy? Answer: 1. If pt. on High FIO2(100%) & PEEP: Lower FIO2 first -below 60%. 2. Once 60% : then begin lowering the PEEP. Question: What is the special consideration for COPD pts. With O2 ? Answer: 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 as stuporous (indicates excessive CO2). Question: what are the of O2 Therapy? Answer: 1. Decrease WOB. 2. of decrease hypoxemia. 3. Decrease Cardiac work requirements. Question: What are the hazards of O2 ? Answer: 1. O2 . 2. Absorption atelectasis. Question: O2 - O2 toxicity- Answer: 1. when pts. FIO2 is >60% or more for more than . Question: O2 - what are the O2 toxicity signs? Answer: 1. Tachypnea. 2. Refractory hypoxemia - a fix hypoxemia w/PEEP/CPAP not FIO2. 3. compliance - decreased surfactant in the lungs. 4. Pulmonary lungs and 5. Nausea. Question: O2 hazards- what is Absorption ? Answer: 1. Caused by rapid changes in FIO2. 2. Alveoli collapse as a result of FIO2 too quickly. 3. Prevent by making small changes in FIO2(10%/less @ a time.) Question: What are the consideration for O2 Hazards? Answer: 1. No smoking. 2. Post O2 in use sign. 3. Instruct pt. and family of the rules and dangers. 4. No electrical devices. Question: What are the O2 mixtures & in O2 Therapy - HeliOx Answer: 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 w/O2. 4.Decreases WOB. 5. Good for pts. w/upper airway obstruction & inflammation. 6.Given w/ a NBR mask Question: What are the O2 mixtures & therapies in O2 - Most common 3 mixtures? Answer: 1. 80/20 - 80% He, 20% O2. 2. 70/30 3. 60/40. Question: What are the O2 mixtures & therapies in O2 - What are the correction factor? Answer: 1.8 for 80/20, 1.6 for 70/30 . Question: In O2 Therapy-Hyperbaric O2 ? Answer: 1. Method of Increasing O2 tension through increasing barometric (in a closed space) 2.Helpful in diseases that require more than 100% O2 @ normal atmospheric pressure can offer. Question: In What situations does Hyperbaric O2 is used ? Answer: 1. CO poisioning. 2. Decompression sickness. 3. Help to heal more quickly. 4. Assist tissue grafts. |
