High/Low Flow Vocab Flashcards
FiO2
Fraction if inspired oxygen
Arterial blood gas
ABG
PaO2 (invasive)
Partial pressure of oxygen in arterial blood
SaO2 (invasive)
Direct measurement of the oxygen saturation of the arterial blood (ABG sampling)
SpO2 (non invasive)
Saturation of arterial blood with oxygen; percentage and measure with pulse oximetry
Hypoxemia
Abnormally low concentration of oxygen in the blood
Hypoxia
insufficient levels of oxygen in the blood; deficiency of oxygen reaching the tissues
Cyanosis
abnormal blueish discoloration of the skin or mucous membranes
Dyspnea
difficult or labored breathing
Sinus rhythm=NSR
normal heart beat 60-100 beats per minute
Tachycardia
abnormally rapid heart rate
Bradycardia
abnormally slow heart rate
Tachypnea
abnormally rapid breathing
Lassitude
a state of physical or mental weariness; lack of energy
Somnolence
a state of strong desire for sleep, or sleeping for unusually long periods
Absorption atelectasis
the tendency for airways to collapse if proximally obstructed with high oxygen concentrations
O2 toxicity
exposure to high PO2 for extended periods of time
ROP
retinopathy of prematurity. abnormal ocular condition that occurs in some preterm low birth weight infants
Indication
a sign or piece of information that indicates something
Contraindication
a symptom or condition that makes a particular treatment procedure inadvisable
FiO2 stability
- variable
- fixed
- Variable=delivered % of oxygen will vary based on liter flow, respiratory rate and depth of breathing
- Fixed = delivered % of oxygen is set no dependent on flow, rate or depth
Acute
abrupt onsent
Chronic
persistent for a long time or constantly recurring
SOB
short of breath
WOB
work of breathing
vasoconstriction
the constriction of blood vessels which increase blood pressure
CNS
central nervous system
cor pulmonale
abnormal enlargement of the right side of the heart as a result of disease for the lungs or pulmonary blood vessels
MI
myocardial infarction (heart attack)
hypertension
high blood pressure
hypotension
low blood pressure
CXR
chest x-ray
infiltrate
the diffusion or accumulation of substances not normal to it or in amounts in excess of normal. The material collected in those tissues or cells is called infiltrate
AC membrane
alveolar-capillary membrane, a thin tissue barrier through which gases are exchanged between the alveolar air and the blood in the pulmonary cappillaries
fibrosis
the thickening and scarring of connective tissue, usually as a result of injury
COPD
chronic obstructive pulmonary disease
hyperventilation
deep, rapid breathing, resulting in a decreased CO2
hypoventulation
breathing slow and shallow, resulting in an increase in CO2
minute ventilation
respiratory rate x tidal volume
Normal rate is 5-10 L/min
patient demand
requirement of oxygen based on disease process
tidal volume
volume of air that is inhaled or exchanged average being about 500 ml
