hyperinflation therapy

patients who are proned to atelectasis would include what
heavily sedated
major trauma
thoracic surgery
bed ridden
clinical signs of atelectasis would include all of the following except
hyperresonant not to percussion
types of incentive spirometers would include what
flow dependant
volume displacement
true or false once a need for SMI has been established the RCP needs to focus on explicit therapeutic outcomes
the RCP is administering an IPPB treatment on the bennett PR2 when they note the machine hesitates before cycling on. what is the most likely cause
flow is too low
the RCP is attempting to give an IPPB treatment with a Mark Bird 7 ventilator the circuit has been assembled correctly, and the ventilator is connected to a 50psi gas source. However, the ventilator will not trigger into inspiration despite the patients best effort. what do you suspect is the problem
the flow rate has been turned off
An IPPB ventilator designed primarily for home use is the
Bennett AP5
terminal flow may be found on the bennett ap5
the bird mark 8 is _______ powered
pneumatically powered
If the flow is too low when administering an IPPB treatment what would you observe
the machine hesitates before cycling on
If an IPPB ventilator fails to cycle into exhalation, the problem most likely would be
there is a leak
when the patient attempts to cycle on teh PR2 IPPB ventilator a -12cmH2O is recorded on the pressure manometer the RCP shoudl
increase the sensitivity
the IPPB ventilator is failing to cycle off, and you suspect a leak, possible places to check would include the following
patients nose
exhalation valve
patients mouth
if the PR2 ventilator had an internal leak the RCP would adjust the ________
terminal flow
BIPAP criteria may include which of the following
cooperative patient
stable hemodynamics
no need to protect airways
hazards to CPAP include all of the following
decreased venous return
decreased cardiac output
True or false hypoventilation is a danger of CPAP
indications for BIPAP include which of the following
COPD, CSA, Neuromuscular dysfunction, OSA
State two reasons that would cause the system pressure to drop more than -2cmH2O on inspiration with CPAP
leak and flow too low
what is the VTE range when setting BIPAP
state two indications for IS
treat and prevent atelectasis
state four hazards of IS
pulm. barotrauma
state two indications for CPAP
suggested CPAP continues tx
treat cardiogenic pulm. edema
state 4 hazards of CPAP
decreased QT
decreased venous return
decreased urinary output
state four indications for IPPB
need to improve lung expansion in presence of atelectasis when other therapy fails
unable to clear secretions
need for short term noninvasive vent. support for hypercapneic pts
need to deliver meds
state five hazards of IPPB
increase RAW
nosocomial infection
resp. alkalosis
decreased venous return
explain why COPD patients do well on BIPAP
blow off CO2
what level of pressure would an RCP start out at when administering an IPPB treatment
10 to 20cmH2O 6-8 bpm exp. 3-4 times longer than ins.
what pressures would the RCP set when administering BIPAP
IPAP -10cmH2O
EPAP -4 to 5cmH2O
what is the indication the RCP has reached optimal lung volumes when administering an IPPB
aeration in the lower lungs
state two parameters on the IPPB that will affect Vt
pressure and Flow
when administering Hyperinflation therapy, what parameters would be measured to indicate the effectiveness of the therapy
SPO2, RR, HR, BS, Xray, sputum
If the IPPB autocycles, what is the most likely cause
If the patient has a hard time cycling off the machine, what is the most likely cause
check for leaks
the most accurate method of measuring inspired volumes is
volume displacement
three methods of volume measurement used in IS include
timing the duration of a flow of gas
volume displacement
photoelectric sensing
gas pressure is regulated in the Bird ventilator by
magnetic attraction opposing gas pressure
gas pressure is regulated in the bennett ventilators by
a low pressure reducing valve
which of the following IS operate by volume displacement
which of the following IS operate using a photoelectric sensor
You are using a Bennett PR-2 ventilator to give an IPPB treatment you want to increase the delivered Vt. You should
increase the pressure
when giving an IPPB treatment, the ventilator triggers on and cycles off rapidly, which control should you adjust
which of the following controls will dilute the FIO2 delivered from a BEnnett PR-2 operating inthe source gas setting
terminal flow control
when giving IPPB therapy using a Bird Mark 7, changes in the delivered FIO2 can be attributed to
venturi gate
