ARTP 10 Flashcards
(50 cards)
Where do you place the circuit after a circuit change?
Needs to be treated as a biohazard and put in biohazard bag
When is a circuit change done?
It is no longer done routinely because it increases the chance of germs getting inside the system. Instead it is changed as needed (when soiled).
Three things that a ventilator pre check ensures
- Ensures there is no leak
- Determines tube compression- makes sure patient receives all the volume of air they are supposed to
- Ensures machine is running correctly.
What are the 4 settings that can affect the i:e ratio
Flow, Ti, TV, RR
***If in VC- you CANT change Ti. And in PC you cannot change flow
If flow increases, i:e does what?
i decreases, e increases
If you increase TV, i:e does what?
i increases, e decreases
If you increase the Ti, i:e does what?
increases the i time, decreases the e time
If RR is increased the i:e does what?
As RR increases, BOTH the i AND e time will decrease
What will cause a sudden spike in RR?
Auto-cycling, which is usually due to the sensitivity being too low
Where is the HME placed?
Placed between the Y and the artificial airway of the pt
Disadvantage to using an HME
Adds additional dead space to the system
Disadvantage to using an HME
Adds additional dead space** to the system and you have to remove it in order to give a SVN.
PS of 7 or less does what?
compensates for the increased WOB due to the increased airway resistance from the ETT tube
What are the most important alarms in CPAP and PS ventilation
Low TV, RR, Pressure, apnea
What do you do if your pt is air trapping?
Want to increase the flow rate
If there is a leak in your system, what two values would you compare?
Their would be a big difference between the VTi and the VTe.
***Which vital sign will help you best evaluate the unwanted cardiac side effects from changing PEEP?
Whenever you are adding additional PEEP, you increase the chance of increasing the pressure set on the heart, decreasing CO. You can best monitor this by looking at the BP*
What does a PS of 8 or more do?
It will help AUGMENT the breath
***If a patient appears to be in distress or asynchronus with the ventilator, what value could you change to improve the situation?
Change the flow….by increasing it?
What temperature is the WICK set at?
35-37
What will increasing the temperature of the heater do?
It will increase the humidity level in the circuit which can help with thick secretions.
***Correlation between expiration time and increased lung compliance
Diseases that increase lung compliance will require a longer expiration time in order to fully exhale the entire volume in their lungs. (Think COPD patients)
***What are your main goals you shoot for as far as initial FiO2 setting?
You want to achieve an SpO2 of 92% and PaO2 of 60-70mmHg
If your patient has auto PEEP, what is likely causing the problem?
If they have auto PEEP, they are probably ‘air trapping’
