Mod 7: Cardiopulmonary Flashcards
decreased PaO2 in blood
hypoxemia
increased PaCO2 in blood
hypercapnia
inc. PaCO2 causes s/s: disoriented, dizzy, cyanosis, stupor & dec. ventilation
respiratory acidosis
dec PaCO2 causes s/s: dizzy, lightheaded, tachycardia, hyperventilation
respiratory alkalosis
dec. HCO3 causes s/s: hyperventilation, HA, weak, cardiac arrythmia
metabolic acidosis
inc. HCO3 causes s/s: nausea, diarrhea, confusion, mm cramps, hypoventilation
metabolic alkalosis
when you fall asleep & wake up a couple hrs later SOB (ex: CHF, PE)
paroxysmal nocturnal dyspnea
type of breathing thats difficult prone/supine but relieved when sitting
orthopnea
type of breathing with prolonged inhalation d/t TBI
apneustic breathing
irregular depths of breathing d/t cerebellar dysfunction
ataxic
FEV1: what it stands for? tests what?
forced expiratory volume in 1 sec
tests pulmonary function
(FEV1/FVC)
FEV1/FVC for restrictive LD vs. obstructive LD
RLD: normal or >80%
OLD: <70%
decreased lung volumes w/ normal expiratory flow rates
RLDs
decreased expiratory flows & narrowed airways but increase lung volumes/capacities
hyperinflated lungs
dec. surface area & gas exchange at alveoli
OLDs
s/s: chronic cough, inc mucus, wheezing, dyspnea w/ exertion, accessory mm hypertrophy
OLDs
s/s: dec. compliance of breathing structures, dec. volume moving in/out lungs, tachypnea, inefficient, inc. accessory mm use, dec. breath sounds, hypoxemia, dyspnea, mm wasting
RLDs
loss of lung compliance causes hypoxemia
inflammatory process that causes irreversible fibrotic scarring of lung walls
dec. TLC, VC etc, dyspnea w/ exertion, cough, sleep disturbances
idiopathic pulmonary fibrosis
/ interstitial lung disease
ideal FITT Rx for respiratory pts
20-30 min/day, 5x/wk
if discontinuous, shorter sessions 1-2x/day
RPE range
6-20
easy- veryvery hard(90% MHR)
what is the increase in Syst BP per MET level?
8-12 mm Hg
secretion mobilization techniques:
postural drainage
percussion
vibration (upon exhalation)
PEP devices
hydration
gen. mobility
assisted & self-assisted cough techniques
respiratory mm training techniques:
paired body motions w/ inhalation/exhalation (thoracic ext/flex)
mm recruitment- diaphragmatic (or accessory mm if only option, COPD)
inspiratory mm training w/ incentive spirometer
what does an incentive spirometer do?
how to perform?
strengthen diaphragm & intercostals for inspiration
full exhale, slow/full inhale & hold 3 sec, exhale; 5-10x/hr
4 stages of effective cough
inspiration > TV
glottis closure
abs & intercostals contract to inc. thoracic pressure
sudden glottis opening & forceful expulsion of inspired air
how to perform self-assisted cough
pt supports abdomen or anchors UEs to inc. intraabdominal pressure
techniques for cough assistance
max inspiratory phase w/ vc, positioning & arm movement
-facilitate w/ tapping, manual cues, arm flexion & head ext
mm contraction & trunk movement to max out intraabd/intrathoracic pressure
“bear down” or dig deep
