Oxygen Therapy NECC

Understanding Oxygen Therapy NECC

QuestionAnswer
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
