220-oxygenation Flashcards
vaping
destroys the areola capillaries making oxygen exchange impaired.
what is essential to normal function of pulmonary system?
oxygenation
Ventilation (ability to transport air to and from lungs)
Oxygenation
(Properly functioning alveolar capillary membrane.
Which oxygenates venous blood & removes carbon dioxide from blood)
Ventilation
(Ability to transport air to and from lungs)
functional units of the respiration system
upper air way- warms filter and humidify
lower airway function- conduction of air, mucociliary clearance
alveolar capillary membrane- gas diffusion
in post op patient what happen if the mucocilliary membrane is not clear
at risk for post op pneumonia
factors affecting pulmonary function
levels of health
medications
lifestyle
environment
things that affect level of health
COPD
Lung disease
HF
Left sides heart failure makes Fluid build up in lungs
Muscle wasting
Anemia
Poor nuturtion
Immobility
Positioning
medication that affect pulmonary
Opioid
Narcotics
Anemia
lifestyle that affect pulmonary
Smoking
Obese
Occupation
factors affecting pulmonary
Pollution
Secondly smoke
Work place
how does age affect respiratory function
decreased oxygenation and ventilation
effects of decreased oxygenation
work of breathing is increased (expiration becomes active)
effects of decreased ventilation
gas exchange is decreased (less capillaries and lung volume)
ineffective cough
drier mucous membranes
risk for aspiration due to decreased gastric motility
impaired mobility
meds that decreased ventilation
tissues and airways get more rigid (diaphragm moves less efficiently which lead to less air exchange)
pulmonary ventilation care
inspection & auscultation
wheezes
Constriction of airways, high pitches on both in and out. (Ventilation problem)
crackles
popping of averola sacks, discontinues found, fine pitched
rhonchi
secretions in large airway, course and discontinues sound, deep pitched
diagnostic methods for pulmonary function
non invasive:
pulse ox
chest XR
Pulmonary function test
invasive:
arterial blood gas
bronchoscopy
pulse ox
measure amount of hemoglobin saturated with oxygen
it uses arterial blood to measure
Pulmonary function test
Assessment of breathing volumes
ABG
ventilation
oxygen
pulse
PH
respiration
to find the paO2 from the spO2
subtract 30 (unless it is 95% spO2 then is is 80% paO2)
nursing interventions for pulmonary function
quit smoking
positioning
chest physiotherapy
pursed lip breathing
fluid intake 2L per day
good nutrition
medications
coughing and deep breathing
Incentive spirometry
when to use cough suppressant
non productive cough
when to use expectorants
productive cough
bronchodilators
open narrowed airways
corticosteroids
reduce inflammation in airways
nebulizer
dispense fine particles of medication into deeper passage of the respiratory tract where it is absorbed
Meter dose inhaler
delivers controlled dose of medication with each compression of the canister
dry powder inhaler
activated by the patients inspiration
what do you do after steroid MDI’s?
rinse mouth otherwise it may cause thrush
