oxygenation Flashcards
what controls breathing?
the respiratory center of the brain- medulla & pons
A:P diameter
the diameter from the front to the back
what happens when to the AP diameter when someone has COPD?
gas cannot exchange properly so their AP diameter expands outward. the AP diameter becomes the same as the transverse diameter 1:2
normal breathing pattern
regular and comfortable at a rate of 12-20 per minutes
bradypnea
slower than 12 breaths per minutes
tachypnea
faster than 20 breaths per minute
hyperventilation (hyperpnea)
faster than 20 breaths per minutes, deep breathing
sighing
frequently interspersed deeper breath, not an abnormal process
air trapping
increasing difficulty in getting breath out, common with asthma
cheyne-stokes
varying periods of increasing depth interspersed with apnea, exhibits end of life
kussmaul
rapid, deep, labored; diabetic ketoacidosis
biot
irregular interspersed periods of apnea in a disorganized sequence of breaths
ataxic
significant disorganization with irregular and carying depths of respiration
which breathing patterns are a result of a neuro injury?
bio & ataxic
PaO2
O2 level in the blood 80-100
PCO2
CO2 level in the blood 35-45
HCO3
bicarbonate level in the blood 22-26
normal bronchiole sound
heard over trachia
normal bronchovesicular sound
heard over bronchioles
normal vesicular sound
heard over the lungs
wheezing
occurs when bronchioles are constricted, common with asthma
crackles
fluid in the lungs, usually indicates pneumonia
ronchi
harsh sounds as a result from congestion
stridor
severe constriction of the airway, emergency
asthma
constriction of the bronchioles
pneumonia
infection in the lungs due to flid sitting in lungs
chronic obstruction pulmonary disease
decreased O2 in alveoli sacs, body begins to compensate for itself
opioid induced hypoventilation
pain medication decreases respirations & shallow breathing
anemia
not enough RBCs, usually low H&H
atelectasis
alveoli sacs collapse, O2 is not being diffused
aspiration
anything that gets into the airway that does not belong there
oxygenation interventions
turn, cough, deep breathe
room air %
21%
pulmonary function testing
used to measure lung size and airway patency
what is a common AP and transverse diameter in someone who has COPD?
AP diameter is the same as the transverse diameter 1:1
normal breathing
regular and comfortable at a rate of 12-20 bpm
bradypnea
slower than 12 bpm
tachypnea
faster than 20 bpm
hyperventilation (hyperpnea)
faster than 20 bpm, deep breathing
sighing
frequently interspersed deeper breath, not abnormal
air trapping
increasing difficulty in getting breath out, common with asthma
cheyne-stokes
varying periods of increasing depth interspersed with apnea, exhibits end of life
kussmaul
rapid, deep, labored, diabetic ketoacidosis
biot
irregularly interspersed periods of apnea in a disorganized sequence of breaths, neuro injury
ataxic
significant disorganization with irregular and varying depths of respiration, neuro injury
bronchial sound
heard over trachea
bronchovesicular sound
heard over bronchioles
vesicular sound
heard over the lungs
