PEEP EXAM QUESTIONS WITH
100% CORRECT ANSWERS
Functional residual capacity - Answer Amount of air remaining in lungs at end of
exhalation
lung and chest wall compliance - Answer FRC is determined by
anything that reduces outward mobility - obesity, ascites, constrictive bandages -
Answer What reduces chest wall compliance?
anything that reduces volume of the lungs - pulmonary edema, fibrosis, consolidation,
increased intra-abdominal pressure - Answer What reduces lung compliance
average pressure above baseline during a total respiratory cycle - Answer What is
Mean airway pressure
increase Mean airway pressure - Answer What is one approach to improving
oxygenation after FiO2 has already been increased
Pip, Peep, I:E ratio, RR, inspiratory flow pattern - Answer 5 factors that affect MAP
affects mean alveolar pressure increasing alveolar recruitment and oxygenation -
Answer Why is Map important
flow resistors & threshold resistors - Answer 2 devices used to apply PEEP
expiratory flow, expiratory retard devices - Answer Flow resistors direct
through an orifice or resistor (such as a screw clamp) and acts as .
pressure - Answer Flow resistors generate a higher w/ a higher rate of flow.
Flow - adjusts pressure based on flow, pressure - constant pressure - Answer Main
difference between flow resistors and pressure resistors.
pressure resistor - Answer Device that provides a constant pressure throughout
expiration regardless of the rate of gas flow.
pressure in patient's lungs matches preset PEEP - Answer Threshold resistors stops
gas flow when
, Underwater seal, weighted ball, spring loaded valves, magnetic valve, Balloon-type
exhalation valve - Answer What are the different types of threshold resistors?
Underwater seal - Answer Type of threshold resistor where expiratory limb is
submerged in a reservoir of water a distance equal to the amount of PEEP required
evaporation causes lower PEEP levels - Answer Main problem w/ Underwater seal
the higher the PEEP - Answer For Underwater seal, the further the tube is inserted in
the water,
Bubble CPAP systems in NICUs - Answer Where are Underwater seals still used today
Boehringer Peep Valve - Answer Weighted ball threshold resistor is aka
Weighted ball - Answer Type of threshold resistor where a ball of specific weight is set
atop a calibrated orifice which creates a threshold of back pressure
in vertical position - Answer Weighted ball threshold resistor must be what?
Spring loaded valve - Answer Type of threshold resistor where PEEP is a result of
compressing a disc on the end of a spring via a threaded knob against an inlet orifice.
Magnetic Valve - Answer Type of threshold resistor where magnetic attraction is used to
create a threshold pressure.
Magnetic valve - Answer Type of PEEP device used in resuscitation bags
Balloon-type exhalation valve - Answer Type of threshold resistor where residual
volume of a gas exerts a pressure within a balloon or against a diaphragm.
PEEP - mechanical ventilation ; CPAP - spontaneous breaths - Answer Difference
between PEEP & CPAP
Increases lung volume, FRC, & lung compliance ; decreases shunt & WOB ;
redistributes water away from alveolar area - Answer Benefits of PEEP
prevents alveoli collapse on expiration - Answer Benefit of Surfactant & PEEP
improve oxygenation, decrease WOB, and reduce auto-PEEP - Answer 3 indications for
PEEP
PaO2 less than 60 w/ FiO2 over 50 - Answer Oxygen indications for PEEP
