Mechanical ventilation waveform interpretation

The breaths shown in the figure are

• Supported

• Assisted

• Mandatory

• Spontaneous

The MV mode in the Figure is

• AC-VC

• SPN-PSV

• AC-PC

• SIMV-VC

This figure represents

• A flow time scalar showing the effect of bronchodilators

• A pressure time scalar showing AutoPEEP

• A pressure time scalar showing effect of bronchodilators

• A Flow time scalar showing AutoPEEP

In this scalar , the difference between the first and the second breath is due to which of the following?

1)Atelectasis

2)Bronchospasm

3)increased airway secretions

4)pulmonary oedema

• 1 and 2

• 1 and 3

• 2 and 3

• 2 and 4

This graph represents

• Flow Volume Loop

• Pressure Time Scalar

• Volume Time Scalar

• Flow Time Scalar

the proper management regarding this case is

• sedation

• consider ETT suction

• increase PEEP

• add bronchodilators

The mode of MV in the figure is

• AC-PC

• SPN-PS

• PPS

• SIMV+PS

The difference between figure 1 and figure 2

• The Pinsp

  was increased by the physician

• The lung compliance Of the patient decreased

• the mode was shifted from AC-VC to AC-PC

• The ETT was blocked

Choose the correct statement

• This graph represents Pressure Volume Loop

• The mode in the graph is a pressure control mode

• The delta P represented by the blue arrow should be kept above 15 cmh20 by titration of TV

• the delta P represented by the blue arrow is a function of both TV and respiratory system compliance

What is the problem shown in the graph

• Air-leak

• Flow starvation

• Auto-PEEP

• Active exhalation
