Lesson 5 Flashcards
stridor
high pitched crowing noise usually indicates by an upper airway obstruction
wheezing
indicates obstruction in the small airway
hyercapnia
increased CO2 levels causing pH level to drop (respiratory acidosis)
occurs in patient with low respiratory effort
hypocapnia
decreased CO2 levels causing pH to rise (more alkaline) decreases RR
what does hypoxia do to cell function
reduces it leading to anaerobic metabolism and the development of metabolic acidosis
kussmauls respirations
deep rapid respirations
“air hunger”
state of acidosis or may occur after exercise
rales
light bubbly/crackling sounds
rhonchi
deeper harsher sounds with thick mucus
dyspnea
difficulty breathing
dyspnea features
tachypnea, tachycardia, difficulty speaking and accessory muscle use
psychogenic vitals
relatively normal
hypoxia
inadequate delivery too O2 to cells
patient will have tachycardia and tachypnea
anoxia
absence of oxygen
hypoxia comes from _________
brainstem
crackling breath sounds
fluid in the lungs
what drives our respiratory rate
CO2
cardiac arrest means…
NO BREATH SOUNDS
common dyspnea causes
COPD
pulmonary edema
ischemic heart disease
pneumonia
hypercapnia
increased CO2
acidosis
confusion, lengthy, seizure coma
cardiovascular collapse
other respiration regulation factors
temp drugs pain emotions activities
accessory muscles used when in respiratory distress
sternocleidomastoid
pectoralis
internal intercostals
abdominal muscles
t/f nasal flaring means there could be airway issues
T!
its a sign of increased respiratory effort/partial airway obstruction
more common in kids
airway questions
what makes it better or worse
symptoms
interventions
medication compliance
subcutaneous emphysema
when gas or air is present in the sub q of the skin
usually a result from trauma
usually happens in the chest neck and face
like touching Rice Krispies
