Vent modes and waves
100
Patients who are ventilated with excessively large tidal volumes are at risk for this
What is VOLUTRAMA
100
Tidal volumes should be at least this amount in the adult patient to be successful at weaning
What is 300 mL or >4mL/kg
100
Increasing this will resolve the problem of breath sacking
What is increasing the expiratory flow
100
This method of weaning may be used to minimize auto-PEEP
What is CPAP
100
These vent modes can ensure delivery of a preset Vt during spontaneous breathing
What are volume-support or VERSUS(Siemens Servo vent 300) and volume-assured pressure support(VAPS)
200
The stacking of breaths seen in mechanically ventilated patients with severe airway obstruction can be caused by this...
What is insufficient expiratory time
200
True or False: the PO1 measure is effort dependent
False!, The PO1 measure is effort INdependent
200
When auto-peep is present, is is most likely detected if the expiratory limb of the patient circuit is occluded at this point in the cycle
What is at the end of exhalation
200
this weaning method provides the best respiratory muscle strength condition
What is T-tube
200
This waveform most accurately allows the technician to recognize auto-peep
What is a FLOW-TIME waveform
300
ARDS, pneumonia, and pulmonary edema are likely to cause a decrease in lung compliance. This is evidenced in a mechanically ventilated patient by this...
What is STATIC PRESSURE
300
Prerequisites for successful weaning include these...
What are physiological readiness. adequate gag, cough, and swallow reflexes, and the ability to follow directions
300
Cardica pressure will increase to compensate for a decrease in oxygen when the PaO@ falls to below this #
What is 50mmHg
300
The development of this cardiovascular change would be a bad sign during the weaning procedure.
What is the development of chest pain
300
This waveform could be used to determine whether there is any leak in the system and the amount of the leak.
What is VOLUME-TIME
400
You make this adjustment when the patient is overdistended according to the graph
What is decrease the Vt.
400
True or False: Antibiotics can depress the ventilatory drive and hinder the weaning process.
What is FALSE, narcotics, neuromuscular blocking agents, analgesics, and hypnotics can depress the ventialtory drive and hinder the weaning process.
400
Under most clinical conditions, the PaO2 should be kept within the range of this
What is 60-80mmHg
400
You would suggest these to a patient who has developed muscle fatigue during a weaning procedure.
What are: make sure there is adequate O2 transport, make sure that the patient is adequately nourished, check and replace depleted electrolytes, and clear secretions with a bronchodilator.
400
Overdistention will look like this on the graph
What is the loop will have a bird beak (I can't draw these, sorry!)
500
I am one question short
Sorry!!

These techniques can help tp decrease a patient's imposed WOB during weaning from the ventilator.
What are the use of pressure-support ventilation (PSV), trigger breath by flow, not pressure, application of small amounts of CPAP or positive end expiratory pressure (PEEP), and the use of automatic tube compensation(ATC)
500
True or False: ventilator graphics can make an assessment of the supply pressure to the ventilator
What is FALSE!!
500
the decision to terminally wean is made by these people
Who are the patient's family and their physician
500
An increase in the size of fishtail indicates
What is an increased WOB to trigger inspiration
