Kania small group lecture/ CIS on Respiratory (10/14) Flashcards
pertinent sympathetics to respiratory
T1-2- upper airway, head. (superior cervical ganglion, stellate ganglion - inferior cervical and 1st thoracic)
T2-6 = bronchioles, lungs
Superior Cervical Ganglion
- fused ganglia of C1 through C4
- provides postganglionic innervation to the head and neck
Stellate Ganglion
- fusion of the inferior cervical sympathetic ganglion with the ganglion of T1
- middle cervical and stellate ganglia innervate the heart, lungs, and bronchi.
pertinent parasympathetics to respiratory
vagus –> lungs and upper airway
pterygopalatine (sphenopalatine) ganglia supply parasympathetic innervation to the sinuses, nose, lacrimal gland, and blood flow to the nasal mucosa
sympathetic stimulation leads to
response tends to be more general
mucus glands and blood vessels are heavily innervated by the sympathetic nervous system
smooth muscles are not
stimulation of the sympathetic nerves in the mucous glands increases water secretion and decreases the viscosity of mucus.
(opens airways to breathe better while running away)
Parasympathetic stimulation leads to
slightly constricted smooth muscle tone in the normal resting lung
innervation is greater in the larger airways, and it diminishes toward the smaller conducting airways in the periphery
bronchial glands, increases the synthesis of mucus glycoprotein and
increases the viscosity of mucus
What’s the biggest problem of SNS activity in a sick person?
blood vessel constriction–> decreased delivery of oxygen, nutrients, removal of wastes, impaired O2-CO2 exchange
why do we want PNS activity in a sick person?
increased synthesis of mucus glycoprotein because it is part of the innate immune system and contains more:
- lactoferrin (antibacterial, antiviral and antifungal, particularly in infants; highest lactoferrin in colostrum, then human breast milk)
- lysozymes (active against G+ bacteria - strep, bacillus. Have reduced activity when glycolated - diabetes
- beta-defensins- cationic proteins that bind to cell membranes of bacteria and fungi and change the permeability; also active against viruses
- IgA- S. pneumo and H flu type B release a protease that destroys IgA
Chapman’s Reflex points- how to approach
treat lymphatics first
posterior points are diagnostic, secondarily for treatment
anterior points are for treatment
treat with vibratory or rotary motion, or deep kneading
Alternative way: hold angerior and posterior points, with connection between fingers, wait for connection to resolve
Most likely causative organisms of sinusitis?
viral
Rhinovirus, coronavirus, influenza A & B, parainfluenza, respiratory syncytial virus (RSV), adenovirus, enterovirus
about 10% proceed to bacterial
fever helps what?
increases lactoferrin, fighting off the critters
sympathetic ganglia are close to
rib heads
Muscles of ventilation: external intercostals
inferrror margin of rib above–> superior margin of rib below
Innervation: intercostal nerves: T1-T11
Most active during instpiration
supports intercostal space
moves ribs superiorly
muscles of ventilation: internal intercostal
lateral edge of costal groove of rib above–> superior margin of rib below deep to the attachment of the related external intercostal
Innervation: intercostal nerves T1-T11
Function: most active during expiration; supports intercostal space, moves ribs inferiorly
Muscles of ventilation: innermost intercostal
medial edge of costal groove of rib above –> internal aspect of superior margin of rib below
Innervation: intercostal nerves: T1-T11
Acts with internal intercostal muscles
Muscles of ventilation: subcostales
internal surface (near angle) of lower ribs –> internal surface of second or third rib below
innervation: related intercostal nerves
function: may depress ribs
muscles of ventilation: transversus thoracis
inferior margins and internal surfaces of costal cartilages of second to sixth ribs–> inferior aspect of deep surface of body of sternum, xiphoid process and costal cartilages ribs IV-VII
innervation: related intercostal nerves
function: depresses costal cartilages
Effects of Kyphosis on Mechanical Ventilation
Reduction of thoracic kyphotic angles demonstrated a reduced vital capacity, inspiratory capacity, total lung capacity, and lateral expansion
There is also a significant negative correlation between the increased kyphotic angle and inspiratory capacity, vital capacity, and lateral expansion of the thorax.
Effects of balloon kyphoplasty on mechanical ventilation
Measured pain scores reduced significantly
FVC and maximum voluntary ventilation (MVV) are significantly increased after 3 days
MVV continues to improve at 1 month afterwards
Decreased pain scores had remarkable positive correlation with improvement of FVC (r=0.536) and MVV 3 days afterward (r=0.614)
Effects of Diminished Lymphatic Flow
Diminished antigen/allergen presentation
- Tissue congestion
- Sinus congestion
- Pleural effusion
- Pulmonary infiltrates
Prolonged recovery from infectious etiologies
Diminished delivery of pharmacologic agents
Anterior Chapman’s Points for respiratory (see separate deck for individual cards)
upper lungs: between ribs 3-4 close to the sternum
lower lungs: between ribs 4-5 close to the sternum
bronchus (esophagus and thyroid): between ribs 2-3 close to the sternum
nose: costochondral junction of 1st rib
tonsils: between 1st and 2nd ribs (1st intercostal space) close to the sternum
sinuses: 3 ½” from the sternum, on the upper edge of 2nd rib and in the 1st intercostal space
** middle ear/otitis media: upper edge of the clavicle, just lateral where it crosses the 1st rib
pharynx: front of 1st rib ¾-1” medial to where the clavicle crosses the1st rib
larynx: upper surface of 2nd rib, 2-3” lateral from the sternum
Posterior Chapman’s Points
upper lungs: intertransverse space, midway between spinous and transverse processes of the T3-T4 vertebrae
lower lungs: intertransverse space, midway between spinous and transverse processes of the T4-T5 vertebrae
Bronchus (esophagus, thyroid): midway between the tip of the transverse process and spinous process of T2 on the posterior aspect of the transverse process
nose: lateral aspect of the transverse process of C1
tonsils: posterior surface of C1 transverse process, midway between the nuchal ligament and lateral most aspect of the C1 transverse process
sinuses: midway between the tip of the transverse and spinous processes of C2 on the posterior aspect of the transverse process
middle ear: (otitis media) upper edge of the posterior aspect of the tip of C1 transverse process
pharynx: midway between the spinous process and tip of the transverse process of C2, on the posterior aspect of the transverse process
larynx: midway between the tip of the transverse process and spinous process of C2 on the posterior aspect of the transverse process
What are the most common causative organisms in community acquired pneumonia?
Streptococcus pneumoniae Haemophilus influenzae Moraxella catarrhalis Rhinovirus Influenza Klebsiella pneumoniae (usu. in ETOHics w/ current jelly sputum)
What are the preferred antibiotics for Community Acquired Pneumonia?
Macrolide
– azithromycin, clarithromycin, erythromicin
Doxycycline
For folks with comorbidities (DM, chronic heart/lung/kidney dz, malignancy, immunosuppression, prior antibiotics within 90 days)
– Fluoroquinolones (moxifloxacin, levofloxacin)
Beta-lactam (+ macrolide or doxycycline)
- High-dose amoxicillin
- Amoxicillin-clavulanate
- Ceftriaxone, cefpodoxime, cefuroxime
Pearls for Asthma (good thing to know for exams and practice!)
Ribcage is children is very pliable
Address dysfunction here quickly to avoid respiratory failure due to accessory muscle fatigue in acute situations
Avoid supine techniques in acute situations
Avoid HVLA in general in kids
Avoid HVLA of thoracic spine (“Kirksville crunch” and Texas twist”) as this would squeeze air out of the lungs
Avoid thoracic lymphatic pump for same reason (pedal pump OK)
Pearls for COPD (good thing to know for exams and practice!)
Avoid supine techniques in acute situations
Avoid HVLA of thoracic spine (“Kirksville crunch” and Texas twist”) as this would squeeze air out of the lungs
Seated HVLA may be useful if patient’s situation is not too acute
Avoid thoracic lymphatic pump for same reason (pedal pump OK)
