-
what is the ideal breathing patter
- slow, deep inspiration
- ins pause 1-3 sec
- exh slow, passive
-
sustained maximal inspiration is aka
incentive spirometry
-
SMI and IS is used for
prevention of atelectasis
-
with IS, pt must be reminded to
inhale not exhale into the device
-
what do you use to prevent or correct atelectasis, pulm edema, dec wob
IPPB
-
hazards of IPPB
- dizziness
- tingling of fingers- instruct pt to breathe slower
- inc icp
-
bird mark 7
- pneumatically powered
- pressure cycled
-
IPPB, increasing pressure will
increase volume
-
IPPB decreasing flow will
decrease turbulance, would expand ins time, will increase volume
-
decrease compliance =
stiff lungs, decrease vol
-
increase compliance =
increase vol, lungs are not stiff
-
increase airway resistance-
decrease volume, bad, obstruction, bronchospasms
-
decrease airway resistance=
increase volume, good
-
what type of compliance and resistance is good
- increase comp
- dec resistance
-
ippb- loss of pressure means
-
ippb- excessive pressure means
- obstruction, secretions
- excessive flow
-
if the pt fails to cycle into inspiration, what should u do
- adjust sensitivity
- tight seal around mouthpiece
-
ippb- fails to cycle off
theres a leak somewhere
-
ippb- pressure does not rise normally
insufficient flow so INCREASE the flow to solve the problem
-
what is the purpose for CPAP
- increase o2
- support oxygenation at lower fio2
-
short term, mask cpap is use for improving oxygenation in pts with
- co2 poisoning
- pneumonia
- post op atelectasis
-
nasal CPAP is useful with neonates since they are obligate
nose breathers
-
loss of pressure indicates
-
increased pressure indicates
- obstruction
- excessive flow, cont venting of the pop off valve will occur
-
indications for non invasive pos press vent NPPV
-
nppv is contraindicated for pts with
dysphagia- problem swallowing
-
o2 must be titrated into the sys to achieve a desired
fio2
-
IPAP (ventilation) should be greater than
epap (o2)
