Exam 3 Fund Of Resp Care Flashcards
Causes of Atelectasis
Low inspiratory tidal volume
Post op pain
Narcotics
Recent upper abdominal surgery
Effects of Atelectasis
Decreased lung compliance
Decrease residual volume
Clinical signs of Atelectasis
- Starts to develop in first 24 hours after surgery and becomes worse over next 24 hours
- tachycardia and tachypnea
- increased temp
- increased WOB
Contradictions of Incentive Spirometer
- if pt can’t be instructed appropriate use
- if pt unable to cooperate
- pt unable to take deep breath
- vital capacity less then 10 ml/kg
When may a patient need an incentive spirometer
- after recent abdominal surgery
- conditions predisposing atelectasis, immobility, pain control, abdominal binders
- presence of neuromuscular disease affecting ventilation
Possible outcomes of incentive spirometer use
- absence of signs or improvement of lung collapse
- decreased RR/WOB
- normal HR and CXR
- improved breath sounds
Difference between flow and volume incentive spirometer
Flow- indirect measurement
Volume- direct measurement
What is splinting
Using a pillow or hands to help stabilize an incision site
Help cough become more effective
Phases of cough
- Irritation
- Deep Inspiration
- Compression
- Expulsion
What is a quad cough?
- abdominal compression
- place hands by belly button and push up
- manual inflation of lungs
How does pt perform a huff cough
Pt takes slow deep breath, inspiratory hold of 2/3 seconds then rapid exhale making a “huff” sound
What is PEP therapy
- Pt breaths w diaphragm at a volume greater then tidal volume but less then total lung capacity
- helps improve mobilization of secretions
Contradictions of PEP therapy
- acute sinusitis
- ear infection
- recent oral, facial or skull surgery
What is a “vest”
- Provides vibrations of lung parenchyma
- uses small gas volume to create vibrations over 30 min time frame
What is a flutter valve
- Combines epap w/ high frequency oscillation of airway
- uses weighted ball
