03 Flashcards
How do you always want to treat pulmonary edema?
When receiving treatment via IPPB, always deliver at FiO2 100%
Pt who has emphysematous blebs are prone to what when receiving IPPB therapy
Tension pnuemothorax and barotrauma
How do you know someone has a tension pneumo?
Shortness of breath, chest pain, and breath sounds (unilateral BS absent??)
What is always treated with 100% FiO2?
Pulmonary Edema
Three main settings on the bird?
Flow, Pressure, and sensitivity
When dealing with flow, what is your standard goal for your inspired time?
1-1.5 seconds
Starting pressure
10-15 cmH20
List the physiologic effects of IPPB therapy
Decreased venous return (can help when dealing with pulmonary edema), increased VT, increased V/Q ration, and decreased WOB.
Three synonyms when referring to pressure
PIP, Peak Pressure, and Pressure limit
Pressure Cycled definition
inspiration ENDS when preset pressure is reached
Correlation between lung compliance and VT?
Positive correlation (if one increases the other will increase)
What is monitored during IPPB therapy
HR/BS/BP
Ideal RR for someone on IPPB treatment
6-8 breaths per minute. (I think this is to avoid the i:e ratio problem of nearing a 1:1 ratio)
What two things, if changed, would require you to adjust your flow as well?
If you change your FiO2 or your Pressure
If you open the venturi, what will the effect be on flow?
Opening up the venturi port will INCREASE your flow, so you would need to decrease your flow to keep your i time.
Your i time is above the 1-1.5 second range. How do you need to adjust your flow?
Increase your flow
If you see the needle on the monometer kinda dragging what should you do?
This means that you need to most likely increase your flow.
What causes a 1:1 ratio?
A really long i time (above 1.5 seconds). This can cause the lungs to hyperinflating and air trapping
What are the three types of ventilation modes?
Assist mode, Assist/Control mode, and control mode
