How do you calculate DESIRED FiO2? |
Desired FiO2 = (PaO2 Des. x FiO2 Known) / PaO2 known |
|
|
What is the clinically acceptable range for PaO2? |
60-100mmHg |
|
|
Following successful cardiac resuscitation, a patient being placed on a mechanical vent should have what FiO2 setting? |
>0.50 up to 1.0 |
|
|
What is the range for flow triggering? |
2-3lpm |
|
|
An intubated patient with COPD has auto-PEEP, what percentage of auto-PEEP should the PEEP be set at? |
80% of patient auto-PEEP |
|
|
If there is an auto-PEEP of 6 and the vent has a pressure trigger setting of 2cmH2O, how much effort is needed to trigger the ventilator? |
8cmH2O |
|
|
With a PIP of 30cmH2O what are the appropriate settings for high and low alarms? |
HIGH = 10-15cmH2O above PIP = 40-45 cmH2O LOW = 5-10cmH2O below PIP = 20-25cmH2O |
|
|
What should the apnea alarm time settings be for a patient on PC-IMV with 12bpm? |
60 / 12 = 5 sec./breath 5 < apnea time > 5 x 2 5 < TA > 10 |
|
|
What are the appropriate low exhaled tidal volume alarm ranges for a patient set with 600ml? |
LOW = 150-200ml < observed VT = 400-450ml |
|
|
How do you minimize air trapping in mechanically ventilated patients? |
Decrease I time to increase E time |
|
|
What is the appropriate mode of ventilation and setting for a responsive COPD patient with an ideal body of 65kg who has a noncritical ABG? |
BiPAP with IPAP 5-10cmH2O EPAP with 2-5cmH2O |
|
|
What is the first step in the assessment and documentation of patient-ventilator interaction following placement of a patient on a mechanical ventilator? |
Verify the order |
|
|
How often should the FiO2 of an adult be measured? |
Every vent check |
|
|
How long after beginning mechanical ventilation should an ABG be drawn? |
10-20min |
|
|
What can increase PIP? |
Reduced compliance Increased Raw Increased Pplat |
|
|
What lung condition causes an increase in peak inspiratory pressure while trans airway pressure remains the same? |
Restrictive |
|
|
What is indicated when PIP is rising while Pplat remains the same? |
Obstruction |
|
|
Is it an airway issue or lung compliance issue when a patients transairway pressure is rising while the plateau pressure remains unchanged? |
Airway issue |
|
|
What should the high-pressure range be if a patient's average PIP is 28cmH2O? |
38-43cmH2O |
|
Identify A, B, C, and D for the PC-CMV scalar: |
A. PEEP B. MAP C. PIP D. Pplat |
|
|
What is happening if the Vt inspired remains the same but the Vt expired is less? |
All volume delivered is the same but the volume returned is less, therefore a leak is present |
|
|
What would happen to the patients trachea when there is a pneumothorax vs. an atelectasis on the left lung? |
Pneumothorax = shift away from affected side Atelectasis = shift toward affected side |
|
|
When percussion is done on patients who have pleural effusions , atelectasis, emphysema, and pneumothorax which ones will have hyperresonance and which will have dullness? |
Dull = pneumonia and pleural effusion Hyperresonance = asthma, pneumothorax, emphysema |
|
|
Cuff pressures should not exceed what range? |
20-25mmHg or 27-34cmH2O |
|
|
To help inflated alveoli from collapsing and reexpanding with each breath, the PEEP level should be set at which point on the deflation part of the loop? |
Above the lower inflection point |
|
|
Low pressure and low VT alarms are sounding on a mechanically ventilated patient, the cuff pressure measures 18cmH2O, what action should you take? |
Perform an MLT |
|
|
If PIP and PEEP remain the same but exhaled tidal volume increases, what change is happening in the lungs? |
Compliance is increasing |
|
|
If PIP and Pplat are both increasing but the gradient between the 2 remains that same, what is happening in the lungs? |
Worsening restriction |
|
|
If PIP is increasing, but Pplat remains the same, what is happening in the lungs? |
Obstruction issues |
|
|
If PIP and Pplat are both increasing, but the gradient between the two pressures is also increasing, what is happening in the lungs? |
Both obstructive and restrictive issues |
