|
What is the functional class of oxygen?
|
Oxidizer
|
Other oxidizing agents include ozone, chlorine, nitric acid, hydrogen peroxide and household bleach (NaClO).
|
|
|
By what mechanism does oxygen act?
|
A colorless, odorless, tasteless gas necessary for the breakdown of glucose into a usable energy form.
|
Gaseous oxygen is actually a very pale blue
|
|
|
What are the indications for oxygen?
|
Presence or suspicion of hypoxemia.
|
Hypoxemia is the decreased partial pressure of oxygen in the blood. Hypoxemia is different from hypoxia, which is an low oxygen availability to tissue, but hypoxemia can cause hypoxia.
|
|
|
What are the listed contraindications for oxygen?
|
None.
|
Never withhold oxygen from a patient for whom it is indicated.
|
|
|
What are the listed precautions for oxygen?
|
- Use cautiously with COPD patients
- Monitor long-term high concentrations in neonate as retrolental fibroplasia may develop - Open flame |
Retrolental fibroplasia (now known as "retinopathy of prematurity") is an eye disease that affects premature infants. Both oxygen toxicity and hypoxia can contribute to its development.
|
|
|
What is the dosage for oxygen?
|
25-100%
|
High-flow oxygen systems include venturi masks, air-entrainment nebulizers and high-flow blender systems.
|
|
|
What is the route for oxygen?
|
BLS and/or ALS airway adjuncts as appropriate.
|
Or no adjunct, if indicated... (e.g. nasal cannula)
|
|
|
What is the relationship between liters per minute of oxygen and oxygen concentration?
|
Every 1 L/minute (LPM) increase in oxygen is equal to a 4% increase in concentration.
Examples: - 1 L/minute = 25% - 2 L/minute = 29% |
Oxygen gas constitutes 20.9% of the volume of dry air. Other gases present are nitrogen (78.1%), argon (0.9%) and carbon dioxide (<0.1%).
