Respiratory Flashcards
(36 cards)
nursing interventions for proper respiration
maintain airway
ensure proper ventilation and oxygenation
**ventilation vs oxygenation
exchange or movement of O2 and CO2 in and out of alveoli - mechanical
oxygenation - exchange of gas
what is work of breathing
amount of effort required to maintain ventilation
what is resistance
opposition - bronchi spasticity
when taking a health hx what questions do you want to ask
hx of asthma, smoking
genetic predisposition
what meds are you taking (how long, how much)
normal blood gas values
pH: 7.35(A) - 7.45(B)
PaCO2 - 35(B) - 45(A)
HCO3 - 22(A) - 26(B)
PaCO2 represents
Respiratory
HCO3 represents
Metabolic
non-invasive respiratory assessment technique
Pulse Ox (SpO2)
to ensure an accurate reading with Pulse Ox (SpO2)
avoid edema, nail polish
min. movement
what does SpO2 measure
oxygen saturation - amt(%) of O2 attached to hemoglobin
oxygen is a drug, t or f
true
Oxygen delivery devices
nasal cannula
high flow cannula
simple face mask
face masks w/reservoirs
oxygen delivery is recorded as
fraction of delivered oxygen (FiO2)
room air is what % of O2
21% or 0.21 FiO2 (21/200)
how much pure O2 is delivered to a pt on nasal cannula
0.24 - 0.44 FiO2
how much pure O2 is delivered to a pt w/hi flow cannula
0.60 - 0.90 FiO2
how much pure O2 is delivered to a pt w/simple face mask
0.30 - 0.60 FiO2
how much pure O2 is delivered w/face mask w/reservoir
partial re-breather 0.35 - 0.60 FiO2
nonrebreather 0.60 - 0.80 FiO2
why do we use an ET tube/intubate
maintain airway
remove secretions
prevent aspirations
mechanical ventilation
why do we get a tracheostomy
long-term medical ventilation freq suctioning protect airway bypass an airway obstruction reduce WOB (work of breathing)
where do we do a tracheostomy
OR or bedside
suctioning is indicated for
secretions r/t increased WOB
coughing
alarms
2 ways to suction
conventional - separate ventilator from pt.
closed - more common - infection
