question
COPD respiratory drive
answer
low levels of oxygen in blood
question
the desired oxygen concentration for pt experiecing respiratory arrest and cardiac arrest _______
answer
100% with nonrebreather
question
low flow system delivers oxygen______ ex:
answer
at flow rates that Supplement* the o2 contained in the room ex: NC, simple mask, partial rebreather, nonrebreather, CPAP, biPap
question
Fi02 delivery from lowest to highest
answer
NC -> venturi mask (most precise) -> simple mask-> partial rebreather -> non rebreather
question
Room air = ______% NC flow rates_______1-6 L
answer
1. 21% 2. 1L 24 % +4% per Liter 3. 6L = 44%
question
NC disadvantages
answer
easily dislodges, skin breakdown
question
with NC _______L and above use _________
answer
3L, humidification
question
simple mask (face mask w/o resivor) 1.set at _____ 2. larger amout will _____ 3. low amounts ____ 4. use a _______ 5. fio2
answer
1. 5L or above 2. 5-8 L will ensure flushing to prevent accumulation of CO2 3. amts lower that 5L may make you rebreath CO2 4. humidified oxygen 5. 40-60%
question
when applying a oxygen mask _____
answer
place on nose than downward
question
partial rebreather 1. setup with ______ L 2. what is it 3. collapsing 4. fi 02
answer
1. 6-10 L 2. rebreathes first 1/3 of exhaled air 3. bag must not collapse more than 1/2 during inspirations to avoid CO2 build up 4. 40-70%
question
non rebreather 1. what is it 2. set at ______L 3. fi02 4. perform_______
answer
1. delivers highest oxygen concentration possible for low flow (except intubation) - has one way valves that prevent room air and expired air from being inhaled 2. 10-15 L/min to keep bag 2/3 full 3. fI 02 of 60-80% 4. perform hourly assessments of valve and flap
question
venturi mask 1. what is it 2. useful for 3. FiO2 4. downfalls
answer
1. delivers most precise concentration 2. used for COPD and shallow breathers 3. 24-60% 4. expensive, humidification required
question
high flow nasal cannulas _____ L used for pt with ________
answer
1. 6-15 L 2. CHF, whlie eating replaces mask -needs humidification
question
CPAP used for pt with ___________ 2. how it works 3. CPAP in babies with _______
answer
1. respiratory failure, sleep apnea, obs sleep apea 2. delivers continuous positive airway pressure during inhalation and exhalation 3. collapsible airways and muscle weakness -premie babies (will slowing get weaned off, called "cycling")
question
BiPap
answer
allow sep pressures for inhalation and exhalation used best when pt is awake -ALS pt
question
1. oxygen toxicity occurs when fio2 _______% 2. s/s 3. intervention
answer
1. 50% 2. cough, dyspnea, susternal pain, burning and posturing 3. decreased Fi02 as Spo2 increases
question
1.small volume nebulizers ran at _____ L/min 2.lower running nebs _______ 3,average nebs should last _________
answer
1. 8-10 L/min 2. causes med to foam and doesnt work 3. 5-8 min
question
ambu bag 1. reservoir ____ L 2. good usage ______
answer
1. 10-15 L 2. 2 people , one with mask , one running bag
question
early s/s of hypoxemia (7)
answer
pale, restless, tachypnea, tachcardia, increased BP, accessory muscle use and nasal flaring
question
late s/s of hypoxemia (6)
answer
confusion, decrease BP, bradycardia, bradypnea, cyanotic, dysrythmias
question
pulse oximeter measures _____ life threatening o2 sat
answer
oxygen saturation of arterial blood -02 is the percent of hemoglobin that is saturated with oxygen -70% life threatening
question
Oral airways 1. used with pt ______ 2. measured ______ 3. insertion for adults and peds
answer
1. unconcious pt bc it stimulates gag reflex 2. measured from corner of mouth to corner of ear or jaw 3. adults - curve upward peds- curve down -with peds remove q 4 hr - perform oral hygiene
question
sputum collection ______ after meals
answer
1-2 hr
question
nasopharyngeal (nasal trumpets) 1. used with 2. length 3. lubrication
answer
1. pt who have gag reflex 2. distance from nose to ear and then add an inch 3. cut with scissor & lubricate with water soluble lubricant
question
CHest tubes supply kit
answer
clamps, vaseline gauze, normal saline
question
Why do we give oxygen (3)
answer
treat hypoxia, decrease work of breathing, and decrease cardiac workload
