Intro to Respiratory Therapy: Hyperinflation Therapy

Incentive Spirometry is also known as...

Sustained maximal inspiration (SMI)*

what are the 2 reasons we use incentive spirometry?

-treat micro-atelectasis

-prevent atelectasis

Intermittent Positive Pressure Breathing (IPPB) is used to treat...

atelectasis

this device can provide early detection of atelectasis or pneumonia by observing decreasing inspiratory capacity levels

incentive spirometer

name 3 hazards of incentive spirometry

-Hyperinflation

-Pneumothorax

-Potential vagal reflex

Name 2 indications for Intermittent Positive Pressure Breathing (IPPB)

-Medication administration to patients who cannot breathe deep

-Postoperative atelectasis

name 4 hazards of IPPB

-Excessive Oxygenation

-Decreased Cardiac Output

-Increased Intracranial Pressure

-Gastric Distention

name 4 contraindications for IPPB

-Pneumothorax

-Nausea

-Increased Intracranial Pressure

-Pulmonary Hemorrhage

the IPPB pressure knob controls the...

Tidal Volume

pressure and volume are ____________ related

directly

what is the initial pressure setting on IPPB?

between 5-7

on IPPB, we set the pressure to achieve AT LEAST _________ times a normal tidal volume

2-3

what does the IPPB Flow knob control?

I-time

Flow and I-time are _____________ related

inversely

what is the initial sensitivity setting on IPPB?

15 (-2cmH20)

the lower the sensitivity, the ___________ it is for the patient to trigger inspiration

harder

if IPPB sensitivity is set too ___________, the machine may start self cycling

high

the apnea knob controls the __________

E-time

Apnea and E-time are ___________ related

directly

what is the initial apnea setting?

7 o'clock position

when the air mix knob is pushed in, what percent of the gas is oxygen?

100%

when the air mix knob is pulled out, room air is entrained. What percent of the gas is oxygen?

40-80%

what is the initial flow rate setting?

20

if the patient cannot cycle the IPPB machine off, how would you troubleshoot?

check for leaks
