Oxygenation Flashcards
Ventilation
Bringing air in and out of body
Oxygenation
Gas exchange at alveolar level
Hypoxia
Low O2 in tissue
Hypoxemia
Low O2 in blood
Eupnea
Normal respiration
Tachypnea
Increased respiration rate
Hyperventilation
Rapid and deep respirations
Hypoventilation
Slow respiratory rate. Leads to CO2 retention and inadequate O2 delivery to lungs
Bradypnea
Low reparatory rate
Apnea
Absence of breathing
Dyspnea
labored breathing
Orthopnea
difficulty breathing while laying down
Pneumothorax
Lung collapse caused by collection of free air within the pleural space
What are the 4 main topics of implementation for asthma
- Promote effective gas exchange
- Help relieve anxiety
- Promote adherence to therapeutic regiment
- Address inactivity intolerance
Characteristics of airway hyperresponsiveness
Inflammation
Bronchoconstriction
Secretion buildup
Crackles
High pitched popping
Rhonchi
Coarse, low pitched lung sounds
wheezing
high pitched whistling sound
Nasal cannula
Fi02 24-50%
Most common
Simple mask
FiO2 40-50%
fitted over mouth and nose
nonrebreather mask
FiO2 >60%
prevents pt from breathing in expelled CO2 while delivering O2
Venturi mask
FiO2 24-50%
O2 deliver at a specified flow rate
