What are three goals of O2 Therapy
1. Correct documented or suspected acute Hypoxemia
2. Decrease symptoms associated with chronic hypoxemia
3. Decrease workload hypoxemia imposes on cardiopulmonary system
What is Laboratory documenta#on for assessing the need for O2 Therapy?
PaO2, SaO2 & SpO2
What is an example of a clinical problem needing O2 therapy?
suspected Carbon Monoxide poisoning
What are bedside findings that would lead to necessity of O2 therapy?
Tachypnea, tachycardia & confusion
What are determining factors for O2 toxicity?
PO2 & exposure #me
What does O2 toxicity primarily affect?
The lungs & CNS
What causes infiltrates in lung parenchyma?
Prolonged exposure to high FiO2
Who does depression of ven#la#on occur in?
COPD pa#ents with chronic hypercapnia
What happens in re#nopathy of prematurity?
Excessive blood O2 levels cause re#nal vasoconstric#on & necrosis
Who is at risk of Absorp#on atelectasis?
Pa#ents breathing small #dal volumes with FiO2 above 0.50 are at great risk
Where are O2 related fire hazards at high risk?
