Q

Mucus production and bronchial hygiene

A

Normal pulmonary tract mucus production is approx 100ml per day and is usually swallowed or reabsorbed in the airway, Bronchial hygiene is appropriate for pt who produce more than 30mL of sputum per day and have trouble clearing it

34
Relative Contraindications
Unable to tolerate increased WOB, ICP> 20mmHg, Unstable hemodynamics, Active hemoptysis, Untreated pneumothorax, Tympanic membrane rupture, Facial/ oral/skull surgery or trauma, Epistaxis, Esophageal surgery, nausea
35
Epistaxis
Nosebleed
36
Hazards and Complications
1. Pulmonary barotrauma 2. Increased ICP 3. Decreased venous return 4. Breakdown of skin 5. Air swallowing 6. Claustrophobia 7. Hypoventilation and hypercapnea
37
Hypercapnia
high CO2
38
Assessment of outcome
1. change in sputum 2. change in breath sounds 3. change in vitals 4. change in CXR 5. change in ABG's/ labs
39
Coughing techniques
Directed cough, Manually assisted cough, splinting, forced expiratory technique (FET) or "huff coughing", Active cycle breathing (ACB), Autogenic drainage (AD), Cough assist (Insuflattor/ Exuflattor)
40
Manually Assisted cough (quad cough)
1. Manual thrust similar to heimlich maneuver, performed during expiration splinting
41
ACB
Active cycle breathing 1. Relaxation and breathing control 2. Thoracic expansion exercises 3. Huff cough
42
AD
Autogenic drainage 1. Varying lung volumes with controlled expiratory flows 2. Cough is suppressed until you complete a cycle 3. Moving secretions from the small, med, large airways 4. Mucus rattle
43
Cough Asisst (insuflattor/ exuflattor)
1. Delivers a positive pressure for 2-3 seconds followed by an abrupt change into expiration created with a neg pressure (mimics a cough)
44
PEP Therapy
Active expiration agains variable flow resistance, preventing airway collapse during exhalation
45
Patient instruction during PEP Therapy
1. Have pt sit up 2. Instruct them to take a slightly larger than norm breath 3. Exhale actively but not forceful (through mouthpiece or mask) 4. Have the pt perform 10-20 breaths per cycle 5. have pt cough 6. Evaluate for independent use (if apparatus allows)
46
Therapeutic pressures on PEP therapy
10-20 cm H2O, pressure is measured with manometer
47
How many breath cycles on PEP therapy
repeat: 4-8 cycles
48
PEP I/E ratio
1:3 or 1:4
49
Total treatment time on PEP therapy
no more than 20 minutes
50
PD (postural drainage)
Invovled the use of gravity to help move resp tract secretions from distal lung lobes or segments into the larger central airway where they can be removed via coughing or suctioning
51
Head down positions should exceed
25 degrees below horizontal (hess- 12 inches for lingula/ RML and 18 inches for lower lobes)
52
Perform PD
every 4 to 6 hours or as ordered, must have adequate hydration for secretion mobility
53
How many PD positions? (times)
approx 11 positions are possible each position is held for 5 to 10 minutes, total treatment time is typically 20-30 minutes up to one hour
54
PD scheduled when
before meal or more than 1 hour after mules or tube feeding. coordinate with pain medications. can be done with percussion therapy
55
Special Beds for rotating/ turning a pt
Rotorest, Rotoprone. Triadyne. May also provide percussion. Prone position
56
Rotorest/ triadyne
bed that holds body and rotates
57
Concerns of PD
may need to modify positions, Medically intensive pt
58
Contraindications of PD
Absolute- unstable spinal cord injuries, Traction of arm abductors, Emphysema, Bronchopleural fistula, Pulmonary embolism, Large pleural effusion
59
Hazards specific to PD
hypoxemia (positional), acute hyptension, pulmonary hemorrhage, pain or injury to muscles/ribs/ spine, Vomiting and aspiration, bronchospasm, arrhythmias
60
Percussion and vibration involves
the application of mechanical energy to chest wall by the use of either hands or various electrical or pneumatic devices- Percussion should loosen secretion- vibration should aid in the movement of secretions toward the central airways
61
Hand clapping
Cupped position-fingers and thumb closed which creates a cushion of air when striking pt, rhythmically strike the chest wall with loose wrists, alternating hands , percuss in circular pattern over a localized area for 3-5 minutes, avoid bony prominences
62
Vibration
1. Performed during exhalation, vibrating the chest wall with hands 2. Mechanical and pneumatic machines provide frequencies of up to 20-30 Hz
63
Oscillatory PEP and high frequency chest wall compression/ oscillation
vest, flutter, acapella, IPV (intrapulmonary percussive ventilation), Metaneb
64
IPV
Intrapulmonary percussive ventilation- a pneumatic device that delivers a series of pressurized gas mini-bursts at a rate of 100 to 225 cycles per min usually with a mouthpiece, contains nebulizer, maintains constant PAP, the percussion is controlled by the pt or person giving the treatment
65
A pneumatic device that delivers a series of pressurized gas mini-bursts at a rate of
100-225 cycles per minutes usually with a mouthpiece
66
Selecting bronchial hygiene
1. Pts motivation/ compliance/ goals 2. physician/ caregiver goals 3. Effectiveness of technique 4. pts learning ability 5. Skill of therapist/ availability, work required 6. disease process 7. Equipment 8. cost
