what is positive pressure ventilation correct answers Power source forces air into lungs
developing a positive interpulmonary pressure that expands the lungs; higher to lower pressure

IPPB stands for correct answers intermittent positive pressure breathing

indications for IPPB therapy correct answers Improve lung expansion, short-term vent support,
deliver aerosolized meds; ex: patients with ventilatory muscle weakness, Atelectasis, stroke,
neuromuscular

When the IPPB machine delivers a higher than normal spontaneous tidal volume, will this
increase or decrease rising PaCO2 levels correct answers decrease

Hazards with IPPB correct answers Elevated intrathoracic pressure, ICP, Pulmonary Barotrauma,
Gastric Distension, Gastric insufflation: neurologically impaired, Hyperventilation, Excess
oxygenation Hyperoxia, increased airway resistance: asthma, airtrapping

Symptoms for elevated intrathoracic pressure correct answers Tachycardia, hypotension,
anxiousness, headache

symptoms of pneumothorax correct answers acute chest pain, dyspnea, decrease in SpO2,
tachypneic

What kind of pressures can cause gastric distension? correct answers pressures that are greater
than 20-25 cmH2O

How can gastric distension be prevented when administering an IPPB treatment correct answers
Mask with NG tube should be placed to avoid excessive pressures

How can you help prevent the patient from hyperventilating when receiving an IPPB treatment?
correct answers maintain 10-12 bpm, coach them, mouthpiece out when exhaling

True or False: An IPPB treatment can cause an increase in air trapping in a COPD patient?
correct answers True

Name an absolute contraindication for administering IPPB correct answers Tension

range 35-45

Like Incentive Spirometer, IPPB therapy is used to manage atelectasis. Specifically, when would
IPPB therapy be indicated over IS therapy? correct answers When patient Is unable to produce
an IC greater than 12 mL/kg or a VC greater than (IPPB) 10-15 (IS) mL/kg or has a post-op IC
less than 33% of predicted value

During administration of an IPPB treatment, you notice the system pressure rises above the set
pressure to end inspiration. What should you instruct the patient to do? correct answers allow the
machine to give you a deep breath

A patient is having difficulty initiating each breath with the IPPB machine. What should you
adjust? correct answers Sensitivity; normal is -1 cmH2O

What control is used to increase the volume delivered by an IPPB machine? correct answers
pressure limit

An IPPB machine cycles on with patient effort but does not shut off. The most likely cause of
this problem is? correct answers A leak in the system

Initial sensitivity should be set at correct answers -1 cmH2O

Initial flow should be set at correct answers 15 L/min

initial pressure should be set at correct answers 15 cmH2O

Units for sensitivity correct answers cmH2O

Units for flow correct answers L/min

units for pressure correct answers cm H2O

CPAP correct answers continuous positive airway pressure

When is CPAP indicated? correct answers enhance lung expansion, treat CHF, shunting,
atelectasis

Positive pressure is maintained through --- and --- phases when receiving CPAP correct answers
Inspiration; expiration
