25
Post-op management of laryngectomy?
-Humidification -No pressure over wounds / grafts - Head up 30° - Dietitian (Restricted oral intake)( Alternative feeding options: NGT, PEG) - Speech Therapy (Communication, Swallowing)
26
What are low lung volumes?
Reduced functional residual capacity and alveolar ventilation
27
What is FRC and why is it important?
volume remaining in the lungs after normal, passive exhalation (~3L) - keeps the small airways open, prevents complete emptying of the lungs
28
Conditions assoc. w/ low lung volumes? (6)
Post-surgery (thoracic, cardiac, abdominal) Rib/Sternal #s Chest wall abnormalities Supine position (bed rest) Pleural effusion Lung fibrosis
29
Aims of breathing exercises/strategies?
Increase lung volume, redistribute ventilation, improve gas exchange -Increase thoracic wall mobility - aid secretion clearance - increase strength, endurance and efficiency of breathing
30
Main types of breathing exercises to increase lung volumes (3)
Bilat./Unilat. basal expansion (thoracic expansion) Sustained maximal inspiration (SMI) Incentive spirometry
31
What is the rationale for breathing exercises?
Distention of lungs (increase transpulmonary pressure) to inflate alveoli Increase lung volumes therefore increase sputum movement
32
2 positions for breathing exercises?
Sidelying or sitting upright
33
Sustained maximal inspiration How does it work?
3 s breath hold at maximal inspiration (TLC) -Redistribution of gas into areas of low lung compliance using collateral ventilation pathways and lung interdependance to re-expand collapsed alveoli
34
What does the evidence say about incentive spirometry for PPC?
Evidence does not support the use of IS for reducing incidence
35
What and when is IS used?
incentive device to perform deep breathing exercise mostly used in paediatrics post surgery
36
What is CPAP?
Continuous Positive Airways Pressure
37
What does CPAP involve?
positive pressure to the airways throughout inspiration and expiration during spontaneous breathing can be delivered cont. or intermittently.
38
Clinical effects of CPAP
splinting of airways (prevents closure) -FRC (collateral ventilation) - increased lung compliance - reduced V/Q mismatch and WOB - increased tidal volume for same amount of effort
39
What is vital capacity?
total amount of air exhaled after maximal inhalation
40
tidal volume
the amount of air you move through your lungs each time you inhale and exhale while you're at res
41
Indications for CPAP
Low lung volumes Obstructive sleep apnoea Acute pulmonary oedema Hypoxaemic respiratory failure (Type 1 respiratory failure)
41
Indications for CPAP in PT
Second line intervention, used when conventional treatment has failed Management of moderate-severe hypoxaemia (resulting from low lung volumes or excessive sputum)
42
Hypoxaemia (Type 1 respiratory failure) is seen where?
Seen postoperatively (UAS, cardiac surgery) Chest wall deformity (# ribs), obesity
43
Evidence for chest PT in cardiac surgery?
No strong evidence for routine postoperative chest physiotherapy to reduce the incidence of PPC
44
What factors affect FRC?
-Body size (decreased w/ obesity, inc. w/ height) - Gender (F>M) - Posture (dec. supine) - Diaphragmatic muscle tone - Lung disease
45
The volume of the lung at which small airways in the dependent region begin to close is called?
Closing capacity
46
How does GA affect FRC?
- reduces due to reduced abdominal muscle tone diaphragmatic dysfunction reduced lung/chest wall compliance reduced phrenic nerve activity
47
What percentage does FRC remain reduced by at 24hrs post surgery?
30%
48
Effects of Anaesthesia + supine pos. on FRC and how it results in atelectasis
reduced FRC - FRC < CC - Small airway closure in dependent regions -> reduced ventilation -> V/Q mismatch -> hypoxaemia + atelectasis
49
How GA affects sputum
Mucociliary clearance ceases 90mins after anaesthesia - Increases musus viscosity - Decreased velocity of mucus clearance
50
How GA and surgery affect cough?
Cough reflex dampened (sedation/opiated + surgical wound) -strength of cough reduced (low lung vol. reduced ability to generate intra abdominal pressure)
51
Post-op, where is atelectasis most common in lung?
Areas closest to diaphragm
52
Post operative pulmonary complications - effect on LOS and hosp. resources
increased LOS and resources used
53
Where are PPC most common in?
Upper abdominal surgery
54
Clinical signs of PPC?
Reduced SpO2 < 90% RA CXR changes (atelectasis/consolidation)  Fever (> 38C)  Altered sputum quantity or quality  Sputum microbiology changes  Raised white cell count (WCC) or administration of antibiotics  Medical diagnosis of pneumonia  Readmission to ICU/HDU with respiratory issues
55
Pre-operative Risk factors for PPC
Co-morbidities (respiratory and cardiac) ASA status (class 3-5) Obesity Age Smoking (current) Pre-Morbid Physical Function Immune Status Emergency vs Elective Surgery
56
Perioperative risk factors for PPC
Type of Surgery Length of anaesthesia Pain Immobility Surgical complications Lack of education about preventative measures ICU admission
57

72
How to do ACBT?
1. Relaxed breathing (normal breathing) 2. Thoracic expansion (DB + SMI, 4-6 breaths) 3. Forced Expiration technique (1 or 2 huffs)
73
Rationale of TEE in ACBT?
Increases lung volume, air flows via collateral channels -air behind secretions assist in mobilising them
74
Rationale for FET?
squeezing effect of EPP to push mucus centrally
75
PEP rationale
Increasing gas pressure behind mucus through collateral ventilation (pushes mucus out of the lungs and opens up regions that would otherwise be closed off) – Stabilises airways by splinting them open during expiration
76
How to do PEP therapy?
mask/Hi-PEP/mouthpiece, 6-10 breath followed by FET
