Mod 3 Test Flashcards
Physical act of loving air into and out of the lungs
Ventilation
Process of loading oxygen molecules onto hemoglobin molecules in the blood
Oxygenation
Actual exchange of oxygen and carbon dioxide in the alveoli as well as the tissues of the body
Respiration
Nasal cannula
1-6L/m
24-44%
Oxygen delivery systems
NRB mask w/ reservoir
10-15L/m
Up to 95%
Oxygen delivery systems
BVM with reservoir
15L/m
Nearly 100%
Oxygen delivery system
Mouth-to-mask
15L/m
Nearly 100%
Oxygen delivery system
Adult
1 breath 5-6 seconds
Child
1 breath 3-5 seconds
Infant
1 breath 3-5 seconds
Hypoxic drive
Back up system to control breathing usually found in End stage COPD PT’s
Phrenic nerve
Innervates the diaphragm muscle allowing it to contract.
Vague nerve
Parasympathetic control of heart, lungs, digestive tract
Liquid protein substance that coats the alveoli in the lungs, decrease surface tension, keeps alveoli expanded
Surfactant
Blood enters lungs through right side of heart bypasses alveoli and returns to left side of heart in an unoxygenated state
Intrapulmonary shunting
The pericardial sac filling with fluid and not allowing ventricles to fill with blood
Cardiac tamponade
Blood clots that form in the pulmonary circulation and blocks the flow of blood through the pulmonary vessels. Prevents blood from going from right to left side of heart
Pulmonary embolism
Systolic BP
Top number (120)/80
Diastolic BP 120/(80)
Bottom number
Epi dose
.3mg lateral thigh
High flow O2
NRB 15LPM
Oral glucose
Between cheek and gum-conscious PT only
3 causes of shock
Pump, container, fluid
Preload
Heat muscle stretches to contract blood throughout the body
After load
Force or resistance against which the heart is pumping
Aspirin
Prevents plate aggregation and helps prevent MI
Nitro given
Systolic over 100mmhg no viagra taken less than 24 hours
How/when bag patient
Respiration’s Less than 8 over 28
Shock due to spinal cord damage
Neurogenic
Bordon flow meter
Flow meter not affected by gravity
Absorption is
Ability to bind and stick to surface
NRB mask percentage
90 percent
Nasal cannula
1-6L/min at 24-44%
Exchange of O2/CO2 in the circulatory system and cells in body
Internal respiration’s
Breathing fresh air into respiratory system and exchanging O2/CO2 between alveoli
External respiration’s
Restlessness,irritability, apprehension, tachycardia, anxiety
Early stages of hypoxia
Mental status change, week pulse, cyanosis, dyspnea
Late sign of hypoxia
Tidal volume of average man
500 L/min
Partial pressure of O2 m(104)and CO2(40) in alveoli
Amount of gas in air or dissolved in fluid such as blood
Chronic low levels of oxygen in blood stimulate respiratory drive bc of chemoreceptors
Hypoxic drive
O2-21%
Nitrogen-78%
CO2-0.3%
Exhaled O2-1.6%
Composition of fresh air
Liquid protein that costs alveoli in lungs, decreases alveolar surface tension
Surfactant
Aerobic metabolism
O2/ glucose is used
Anaerobic metabolism
Without 02 cells don’t convert glucose into energy all the way, leaving lactic acid
0-1—irritability 0-4—brain damage not likely 4-6—possible 6-10—likely Over 10—irreversible
Brain not getting o2
