Pulmonary Patient Flashcards
Respiratory infections
- begin with decreased host resistance
- initially PSN activity is increased–mucous secretion becomes more profuse and watery, this is the body’s attempt to flush the pathogens or irritations out of the area
- eventually visceral afferent impulses to the spinal cord increase
- share pathways with sympathetic system
- leads to autonomic imbalance and thus facilitated segments at the level affected
- permits viscerovisceral and viscerosomatic reflexes to occur, increase the SNS output to the respiratory epithelium, increase motor output to somatic structures
Sinuses and head structures visceral afferent/SNS
T1-4
Bronchioles visceral afferent/SNS
T1-6
Ribs at
T1-12
Goals for osteopathic manipulative management of pulmonary infections
- normalize autonomic tone (neurologic model)
- improve thoracic cage compliance (biomechanical model)
- enhance lymphatic return to the heart (fluid and respiratory model)
- reduce contributions to the facilitated cord segments and reduce hyper sympathetic tone to the lungs (neurologic model)
- maximize efficiency of the diaphragm (fluid and respiratory model)
- treat secondary effects (metabolic model)
Characteristic pathologic changes in COPD
- destruction of septal walls of alveoli
- loss of elastic recoil
- destruction of vascular bed
- fusion of adjacent alveoli producing large abnormal airspaces (blebs or bullae)
CXR findings in COPD
- flattened diaphragms, hyperinflated lungs, thin appearing heart and mediastinum
- parenchymal bullae or suprapleural blebs in patients with emphysema
- increased AP diameter (on a lateral CXR)
- increased pulmonary vasculature
Musckuloskeletal structural changes in COPD
- barrel chest
- hypertrophied accessory muscles
- increased kyphosis
- T spine immobility and dysfunction
- rib and diaphragm restrictions
increased Sympathetic tone in COPD
- hypertrophy of the mucosa
- increased goblet cells
- increased secretion of mucous (thick)
- mucus plugs hard to expectorate
- causing air trapping, bronchiectasis
- can trap bacteria and allow secondary infection
Decreased ciliated epithelial cell efficiency in COPD
-small airway plugging due to decreased clearance of the thick mucous
Reactive bronchospasm in COPD
- couples with thick mucous and decreased cilia action to worsen mucous plugging
- can lead to for pulmonale if respiratory function further decreases
Forced vital capacity in COPD
- decreases
- forced exhalation collapses small bronchi and further traps air
- patient exhales with pursed lips to maintain high intrabronchial pressure
Sympathetic innervation T2-7 in COPD
- activation of somatic afferents from the lungs results in widespread tissue texture changes
- resulting somatic dysfunction further increases afferent drive
- more stress–exacerbates the inflammatory response
- more inflammatory and neuroendocrine/immune responses
Increased AP diameter in
COPD
- accommodate the trapped air and increase lung residual volume capacity
- resting diaphragmatic tone increases and diaphragm becomes flattened
- Length-tension relationship
- decrease in blood supply and O2 delivery/consumption ratio
- muscles forced into aerobic metabolism, increased lactic acid
- transitional ares of spine are placed under increased stress
- respiratory motion in these segments reduced
Overuse of accessory muscles in COPD leads to
- cervicothoracic and rib somatic dysfunction
- irritation of the phrenic nerve from cervical somatic dysfunction can reduce diaphragm function
COPD treatment
- risk factor modification
- symptomatic relief with short-acting bronchodilators
- bronchdilation with anticholinergics
- inhaled steroids for decreased inflammatory response
- PO steroids for severe exacerbation
- Abx as needed for infection/infection prevention in acute exacerbation
Asthma
- obstructive process secondary to bronchospasm and mucous plugging
- hyperparasympathetic drive, impaired lymphatic drainage
Chapman’s reflex points for lungs, viscerosomatic reflexes in
T1-6 region bilaterally
Treatment of Astham acute exacerbation
- short-acting bronchodilators
- PO/IV steroids
Maintenance therapy for asthma
-inhaled steroids, long-acting bronchodilators, leukotriene inhibitors
OMT and Respiratory Disease
- many musculoskeletal patterns arise as a reflex or mechanical response to pulmonary dysfunction and respiratory disease
- the osteopathic physician should address these considerations as well as supply any necessary pharmacologic or supportive measures
- OMT can reduce the pain and immobility associated with somatic dysfunction related to pulmonary disease as well as enhance or accelerate the healing process
OMT Respiratory treatment in general
- emphasis on maximizing homeostasis
- normalize sympathetic tone: rib raising, paraspinal inhibition
- normalize PNS tone: sub occipital release
- Address lymphatics
- address specific SDs: normalize rib motion; thoracic dysfunction
Specific areas of need in OMT treatment of respiratory problems
- upper T spine, ribs, sternum
- T1-6
- OA/vagus nerve course
- accessory muscles
- anterior cervical fascia
- thoracic diaphragm
- chapman’s reflexes
- cranial mechanism
- T10-L2/lower ribs/quadratus lumborum
Contraindications and Precautions to OMT in pulmonary problems
- don’t treat in supine position (relative)
- avoid forceful direct methods acutely
- do not over treat and tire the patient
- avoid positions that may restrict respiratory efforts
