Noninvasive Positive Pressure Ventilation
Questions And Answers
What are the three types of noninvasive ventilation? - ANS - negative pressure ventilation
- positive pressure ventilation
- abdominal displacement ventilation
Negative pressure ventilators are also called what? - ANS body ventilators
Negative pressure ventilators operate on the principle of increasing lungs volumes by
intermittently applying negative pressure where? - ANS to the entire body below the neck
or just to the upper chest region
Intermittent positive pressure ventilation (IPPV) uses a pressure targeted ventilator and what
interface? - ANS mask
intermittent positive pressure ventilation (IPPV) was later used primarily to treat what? - ANS
ARF complicated by COPD & asthma
Using a mask or mouthpiece, Intermittent positive pressure breathing (IPPB) became a means
of delivering what? - ANS aerosolized medication periodically with positive pressure
breaths
What are the 7 goals of NIV in the acute care setting? - ANS -reduce the need for

-reduce need for sedation
What are the 4 goals of NIV in the chronic care setting? - ANS -alleviate symptoms of

- "do not intubate" patients
NIV improves gas exchange by resting ______ muscles and increasing ______ ventilation -
ANS -respiratory muscles
-alveolar ventilation
resting of the respiratory muscles and improved TV leads to an improved ______, better _____,
and decreased ________ rates - ANS PaCO2, oxygenation, respiratory
When PEEP is applied during PSV, it helps offset what? - ANS auto-peep
Off-setting auto peep reduces the work required to do what? - ANS initiate inspiration
Pressure support (PS) facilitates inspiration thus increasing what? - ANS TV
What are the exclusion criteria for NIV? - ANS -respiratory arrest/need for immediate
intubation
