Oxygenation Exam 2 Flashcards
(43 cards)
What is hypoxemia?
Low oxygen levels within the blood
mia-blood
Common causes include respiratory conditions like COPD, pneumonia, asthma, as well as old age, smoking, and high altitude.
What is hypoxia?
Low oxygen levels in the tissues of the body
xia-tissue
Hypoxia is sometimes associated with hypoxemia but not always.
What is the average tidal volume in adults?
400-500 ml
Tidal volume is the volume of air inspired and expired with each breath.
What does FiO2 stand for?
Fraction of inspired oxygen
FiO2 increases with nasal cannula, masks, BiPAP, or mechanical ventilation.
What is the oxygenation percentage of room air?
21% oxygenation
What is the oxygen delivery percentage from a 2 liters nasal cannula?
28% oxygen
What nursing intervention can help clients receiving high levels of oxygen through a nasal cannula?
Comfort measures
This may include humidification or adjusting the flow rate.
True or False: Oxygen administration will fix carbon dioxide levels.
False
Clients with decreased lung compliance may still retain CO2 despite oxygen administration.
What therapy benefits clients with decreased lung compliance?
BiPAP therapy
BiPAP provides both oxygen and positive airway pressure to help exhale CO2.
What is the purpose of BiPAP?
To provide oxygen and positive airway pressure
It also helps with exhalation of carbon dioxide.
What should a nurse monitor for in a client with elevated CO2 levels due to COPD?
Assessment findings such as confusion or shortness of air (SOA)
What oxygen saturation level is realistic for a client with a history of COPD?
Lower than normal saturation levels
Specific levels may vary based on individual conditions.
Fill in the blank: A client admitted with sleep apnea may show _______ as symptoms.
[Common symptoms such as loud snoring, daytime sleepiness, etc.]
What cues would indicate the client’s current regimen isn’t working?
Signs of increased respiratory distress or worsening symptoms
What nursing interventions should be taken for a client with suspected sleep apnea?
Monitor sleep patterns, assess respiratory status, educate on lifestyle changes
Additional interventions may include weight management and CPAP use.
What questions may the nurse want to ask the family of a client with confusion?
About the client’s recent health changes, medication adherence, and any known triggers
What labs would the nurse analyze to validate confusion in a client with COPD?
Arterial blood gas levels
Fill in the blank: _______ will help lower CO2 and increase oxygen levels.
[Oxygen therapy]
What are some nursing interventions for those with pulmonary disorders?
Encourage pulmonary toilet, assess lung sounds, position in Semi to High Fowler’s, monitor oxygen saturation
Additional interventions include monitoring skin color and respiratory effort.
What lung sound indicates an emergency?
Wheezing or stridor
What discharge considerations should be taken into account for a client going home with oxygen?
Oxygen needs and follow-up care
What education should be provided to a client going home with BiPAP?
How to properly use and maintain the BiPAP machine
This includes troubleshooting common issues and understanding therapy goals.
Bipap vs cpap?
Bipap for COPD Different air pressure levels for inhale and exhale
CPAP for SLEEP APNEA- only oxygen 1 way valve. Same pressure on inhale and exhale
What s/s would the nurse expect to see in a client in respiratory distress?
anxiety
