pulm Patho Flashcards
pulm questions
any resp/lung problems- severity, tx? do you see a pulmonologist? recent hospitalizations recent exacerbations? recent URI exercise tolerance: can you walk up a flight o stairs? SOB, Wheezing- last exacerbation, tx Smoking OSA- snoring, pillows, HA, wake up SOB, daytime tiredness previous lung surg position--how it will effect V/Q
pulm meds
abx
steroids
beta agonist
Mucolytics (anticholinergics)
meds to mobilize secretions
mucolytics hydration Aerosol therapy mechanical therapy abx
Meds for bronchospasms
B2
anticholinergics
methylxanthines
corticosteroids
Pulm tests
PFT
Abg
O2sat
PaCO2
PFT included 6
VC FVC- forced vital capacity FEV1- forced expiratory volume in 1sec FEV1/FVC FEF25-75- the mean forced expiratory flow MVV: max voluntary vent what are the results-mild mod severe are there trends? improvement with tx?
Not included in PFT
FRC
need nitrogen washout to measure
who needs PFT 8
COPD smokers with cough Wheezing or DOE morbid obesity thoracic surg open upper abd >70yo chest wall or spinal deformities
tests for gas exchange
Abg
SaO2
capnography
assesses mechanical dysfunction of lungs and chest wall
IS
Spirometry
Pulm Labs
CBC for WBC
Pulm physical assessment:
observe and inspect
Pulm observe and inspect
breathing rate, pattern, effort, accessory muscle use SOB wheezing Cough Tracheal position expansion of thorax: barrel chest goiter/mass Skin: color, nails, clubbing of fingers
auscultate
anterior posterior (better) lateral each side
*Tracheobronchial tree: bronchial sounds
trachea, R sc joint and R post is space
high pitch, louder, e=i, pause
*Vesicular: over lung tissue
lower pitch, softer, exp shorter NO pause
maximize pulm function
smoking cessation
mobilization of secretions
bronchospasm tx
improve motivation
Pulm prevent
atelectiasis
barotrauma
worsening VQ-PPV
increased dead space- by provided adequate BP
Smoking cessation
ideal 8 weeks
12-24hr preop: able to better oxygenate bc carboxyhemoglobin levels back to normal
2-3 weeks: increased secretions bc mucociliary function returned
4 weeks: decreased secretions
8 weeks: decreased post op pulm complication
Restrictive pulm disease
sedation
regional
inhaled agents
dec FRC: careful with sedation
Regional: >T10…not good if they rely on accessory muscles?
Inhaled agents: accelerated uptake bc dec FRC
Restrictive: mech vent
Expect increased airway pressures dec TV: 4-8ml/kg inc rate 14-18 PEEP Pressure control
Restrictive anesthesia effects on FRC
dec: supine
dec: GA
plateau develops after 10 mins
may take 3-7 days to recover after abd procedure
VC dec 40% takes up to 14 days to recover
Restrictive: mech vent
can't get IN Expect increased airway pressures dec TV: 4-8ml/kg inc rate 14-18 PEEP Pressure control
Obstructive Pulm disease
can’t get OUT
avoid spont vent on GA
hyper vent can cause air trapping
Obstructive reduce airway reactivity
bronchodilator therapy
inc alveolar [ ] of IA
IV opioids prior to airway manipulation
Steroids
Obstructive vent settings
large TV slow RR keep PIP below 40cmH20 goal=balance avoid high peak airway pressure allow longest possible exp time
PFTs in detail LOOK in NOTES: back side of hand written
lung
Abnormal breath sounds
bronchial: anywhere other than expected Absent Consolidation: low pitch bronchial Cavitary: high pitch bronchial Adventitious: wheezing, stridor, crackles
