Recognizing Cues
Why does the doctor order a CBC for someone with possible impaired gas exchange
To check for infection and oxygen carrying capacity
Identify the purpose and an example of a Bronchodilator
Reduce bronchospasms and reduce irritation (albuterol)
What angle should the HOB be to promote effective gas exchange
Semi-Fowlers. 35-40 degrees
What type of prevention is the best way to prevent impaired gas exchange
Primary prevention
Define Gas Exchange
Transport of oxygen to the cells and carbon dioxide away from the cells
What is the purpose of a PFT (pulmonary function test)
measure lung volume, capacity, rate of flow, and gas exchange
Identify the purpose and an example of a Mucolytic
Manage mucus hypersecretion (acetylcysteine, erdosteine)
What is the purpose of cough and deep breathing exercises
lowers the risk of infection and helps clear airways
What type of breathing improves gas exchange
pursed lip breathing
In what organ does gas exchange primarily occur in the body
In the lungs
Name 3 things to assess for impaired gas exchange
Breathing effort
Oxygen saturation
Capillary Refill
Thoracic Expansion
Lung sounds
Cough, Sputum, SOB, Dizziness, CP,
Cyanosis
Identify the purpose and an example of an Antimicrobial
fight infection caused by bacteria, viruses, fungus, or parasites (vancomycin, acyclovir, amoxicillin)
Identify 3 types of oxygen delivery systems
nasal cannula
simple face mask
non-rebreather
CPAP/BIPAP
high flow nasal cannula
face tent
Handwashing
Smoking cessation
Vaccinations
What is the function of the alveoli
Gas exchange
Identify 4 diagnostic tests associated with gas exchange
ABG’s
CBC
Chest X-Ray
CT or V/Q Scan
PFT
Broncoscopy
Sputum Collection
Identify the purpose and an example of an Antihistamine
Relieves symptoms of allergies when too much histamine chemical is released (Zyrtec, Claritin)
What is the purpose of an incentive spirometer
Your patient is going home on oxygen, where do they need to assess frequently for skin breakdown?
Their nares, cheeks, and behind the ears
Identify 4 risk factors that impair gas exchange
Age, Environment, Diaphragm functioning, impaired brain/spinal cord functioning
What adventitious lung sound is due to narrow airways
Wheezing
Identify the purpose and an example of a Glucocorticoid
reduce inflammation in the body (prednisone, decadron)
Physician, respiratory therapist, speech therapist, ang physical therapist
True or false: your patient on oxygen can use petroleum jelly around the inside of their nares
False: they need to use a water-based lubricant or cream
Respiratory acidosis
