Oxygen
purpose
room air(21% oxygen)
considered a medication
What does every respiratory disease has?
Hypoxia
3 ways to monitor Hypoxemia and Hypoxia?
Oxygen Saturation continuous monitoring, pulse oximetry, arterial blood gases
Symptoms of Hypoxemia/Hypoxia
anxiety, increase pulse rate. high blood pressure, increase depth of respirations,
dyspnea, use of accessory muscles, cyanosis, fatigue, dizziness
Which of the following causes an increase in a patient's oxygen needs? Select all
that apply
(not watching tv)
pain, anxiety, fever, walking, eating, talking
Concentrator
oxygen regulator
Cylinder
oxygen regulator
,oxygen flowmeter
oxygen regulator
Can you add humidification to the oxygen?
only for greater than 4L/min
Can you apply petroleum based lubricant to the nares ?
No
Can the tubing prongs be facing up?
No, they should be down
The nurse is assessing a patient with oxygen at 2 liters/nasal cannula. Which
actions by the nurse are appropriate? Select all that apply
1.Check the patient's ID
2.Check the HCP order
3.Obtain an O2 saturation level
4.Auscultate the lung sounds
5.Make sure the oxygen is working
Flow rate for nasal cannula
1L/min-6L/min
FiO2 rate %
24%-44%
Placement for nasal cannula
•Place the curved cannulas into the nares facing down toward the patient's chest
Nasal cannula
, low flow
oxygen conserving
comfortable
Simple Face Mask
low flow, for short term oxygen therapy
Simple face mask flow rate
Delivers 35%-50% (dependent on flow (6-12 L/min) and breath depth
Need physician order when?
any time you remove them
Face Mask with Reservoir
a bit higher flow
bags must be inflated
for partial nonrebreathers and nonrebreathers
Flow rate of Face Mask with Reservoir
•Deliver 60-90% (10-15 L/min-flow rate MUST be high enough to prevent collapse of
bag)
Venturi mask
high flow, •Cone shaped high-flow device of various sizes
Venturi Mask
most precise delivery of FiO2%
24%-50% FiO2 delivered
High-Flow Nasal Cannula
