Understanding Oxygen Therapy NECC
Question | Answer |
---|---|
List the 3 clinical objectives for oxygen therapy Egan's p.868 | 1.Correct documented/suspected acute hypoxemia 2.Decrease the symptoms of hypoxiemia 3.Decrease the work of the heart related to hypoxemia |
List 2 indications for the use of oxygen therapy Egan's p. 869 | 1. PaO2<60 2.SaO2/SpO2<90%on room air 3.Severe Trauma 4.Acute MI 5.Postanesthesia |
Symptoms of mild/moderate hypoxemia involving the respiratory system Egan's p.870 | 1. Tachypnea 2. Dyspnea/SOB 3.Pale skin color |
Oxygen toxicitiy primarily affects which branch of the nervous system Egan's p.870 | The Central Nervous System (CNS) |
Low Flow Oxygen Delivery Devices include: Egan's 873 | 1. nasal cannula 2. nasal catheter 3. transtracheal catheter 3. simple face mask 4. partial rebreathing mask |
What is the proper flow range for an adult using a nasal cannula? Egan's p. 874 | 0.25-8 liters per minute |
What is the flow range for a simple mask? | 5-10 liters per minute |
Why is the minimum setting of a Nonrebreathing mask 10 liters? Egan's p.874 | To prevent the reservoir bag from collapse on inspiration |
Variables that raise the FiO2 received from a Low-Flow O2 system include: Egan's p.877 | increased O2 output, Mouth-closed breathing, low inspiratory flow, slow respiratory rate |
Variables that lower the FiO2 received from a Low-Flow O2 system include: Egan's p. 877 | Low O2 output, Mouth-open breathing, Rapid respiratory rate |
What is the tank conversion factor for an e cylinder filled with oxygen? Egan's p.851 | conversion factor is 0.28 |
What is the formula used to determine the length of time a cylinder of oxygen with 2000psi will last at 4 liters per minute? Egan's p.851 | the answer is 2000 X 0.28 = 560 divide the answer by the liter flow 560/4 = 140 minutes or 2 hours 20 minutes |
What color is an oxygen tank in the United States? Egan's p.848 | Green |
What are the pin locations on an oxygen tank using the pin-index safety system? Egan's p.857 | The pin index hole positions are 2 and 5 |
What effect does supplemental oxygen have on the heart of a hypoxemic patient? Egan's p.868 | Supplemental oxygen reduces the need for an increase in cardiac output to meet tissue demand |
What effect does too much supplemental oxygen have on a patient with COPD? Egan's p.871 | Too much oxygen for a COPD patient can cause a depression in ventilation by "knocking out" their hypoxic drive |
What causes Retinopathy of Prematurity? Egan's p.871 | retinopathy of Prematurity is caused when low-birth-weight and/or premature infants receive too much supplemental oxygen |
What risk is posed by providing supplemental oxygen at an FiO2 greater than 50%? Egan's p.872 | FiO2s greater than 50% can lead to Nitrogen wash out resulting in Absorption atelectasis |
Define High-Flow oxygen system? Egan's p.880 | A high flow oxygen system is defined as a system that meets or exceeds the amount of oxygen required by the patient |
Names 2 types of oxygen enclosures Egan's p.888 | oxygen tent and oxygen hood |
