Resp 2.7

basic ventilator function.. Flow patterns

Square Constant wave
How is the square created by using high pressure source greater than resistance of lungs
Square charcteristics flow on insp peaks up and stays constant, flow is not affected by changes in airway resistance and lung compliance, decreases insp time, aids in air distribution
Caution for square can increase peak insp pressure and may increase overall mean airway pressure (MAP)
Sine non constant
Sine charcteristics produces some pattern breath after breath, flow picks ups then slows down, slower flow, less resistance is created; therefore usually get lower peak insp pressures.
Caution for sine may result in a decrease in mean airway pressure (MAP)
Tapered decelerating
Tapered picture flow rate at the beginning of insp is high then decreases
Tapered charcteristics tapered wave decelerates flow and decreases peak insp pressures (help keep MAP low)
Caution for tapered may increase insp time to the point that the result is an overall MAP increase

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
