LET Flashcards
What is another name for LET
Hyperinflation therapy
What demographic benefits the most from pursed lip breathing
COPD
IS Description
Low-level resistance
Maximum inspiration
Goal-oriented
Flow or volume
How much PEP is delivered to patients with (PEP)
Up to 20 cm H2O
What is the use of the PEP mask
Intermittent therapy
How should the patient exhale using PEP
Gently
How much long should exhalation last for PEP compared to inhalation
Three times longer
What should a patient do after preforming PEP
3 huffs
What anatomical pressure does CPAP elevate
Intrathoracic
Alveolar
What capacity does CPAP increase
FRC
Is CPAP delivered continuously or intermittently
Both
Is CPAP delivered invasively or non-invasively
Both
Explain bubble CPAP
A water column threshold resistors
Water is adjusted to achieve pressure
Used with neonates
Uses continuous flow source at a specific FiO2
Explain CPAP spring-loaded valve (how much pressure)
Creates PEP as spring exerts force against plastic disk
5-20 cm H2O
AMBU PEEP valves
Explain CPAP magnetic valves (pressure)
Uses a solenoid to create a electromagnetic force when current passes
3-30 cm H2O
Used in mechanical ventilator
BE142 magnetic PEEP valves
What triggers IPPB
Spontaneous breathing
How is IPPB cycled
Flow, pressure, or time
How is IPPB utilized
Stand-alone positive pressure device
Invasive or non-invasive ventilator
Is IPPB powered with pneumatic or electric
With either one
Settings for IPBB application
Inpatient, outpatient and home
Interface for IPPB
Mouthpiece
Mask
Mouth shield
Direct connection to artificial airway
IPPB brief treatment length
20 minutes to 1hour
How is the patient seated for IPPB
Semi fowler
Pressure for IPPB
10-15 cm H2O
Use for IPPB
Postoperative atelectasis
Inspiration to expiration ratio for IPPB
1:3
What is EzPAP a hybrid of
IPPB and PEP
What does IPPB enhance
Collateral ventilation
Flow range for EzPAP
5-15L/min
When is pressure delivered with EzPAP
Exhalation
What decreases the PEP received with EzPAP
Greater inspiratory flow
EZPAP versus IS
EZ- positive during inspiration and expiration
Usually more comfortable to patients (pressure can be uncomfortable)
Directions for directed cough
Deep breath and hold with abdominal muscles forcing air to closed glottis
Cough with a single exhalation
Take several normal before next attempt
Huff cough directions
3-5 diaphragmatic breaths
Exhale from mid to low lung (clears peripheral AW)
Take normal breath and squeeze out by contracting abdominal and glottis
Exhale from high to mid lung when secretions reach larger AW
Indication for mechanical cough assist
Trauma
Muscular dystrophy
Myasthenia gravis
Poliomyelitis
Spinal cord injury
What is autogenic drainage
A technique that uses large breathes out to loosen mucus in the lungs (CF kids)
How do you preform Auto drainage
Take a large breath in, hold in
Take a small to normal breath in and hold
Breath out through the mouth
Inspiratory and expiratory flows for the mechanical cough assist
3.3 to 10L/sec
Positive and negative pressure for mechanical cough assist
60 to -60 cm H2O
Mechanical cough assist interfaces
Oronasal mask
Mouthpiece
Connection to ETT
