Respiratory Lab 1 Flashcards
what is included on a respiratory assessment: History
medical history of allergies, current health problems and current meds, genetic risk, social history including smoking, drug use, travel, and deployment
what is the difference in hypoxemia and hypoxia
hypoxemia = decrease O2 in the blood
hypoxia = decreased O2 in the tissue
what is the goal of O2 therapy
use the lowest fraction of inspired O2 for acceptable blood O2 levels without causing harmful side effects
when should you give humidifed air
over 4 L
what are the hazards of O2 therapy
combustion oxygen toxicity, drying of mucus membranes
what is the L range of nasal cannula
1-6L
what is the FIO2 % for each L of nasal cannula
1L= 24%
2L= 28%
3L= 32%
4L=36%
5L=40%
6L=44%
what is the max % a simple face mask can deliver
40-60%
what is the minimum L for simple face mask
5L/min
what is the % to L for simple face mask
5L= 40%
6L= 45-50%
8L= 55-60%
how much o2 does a partial rebreather mask provide
60-70% and 6-11L
what delivers the highest amount of O2 level of the low flow systems
non-rebreather mask
who is the non-rebreather mask used for
unstable who may require intubation, insures valves are patent and functional
how much 02% does the non rebreather give
90%
what is High flow nasual cannula
combo of heat and humidity, minimizes damage to mucus membranes
what is the L range for high flow nasal cannula
30-60
how does a venturi mask work
pulls in proportional amount of room air for each L flow of O2
how does a T piece work
delivers desired FIO2 to patients with tracheostomies, larygnectomy, ET tube, aerosal should appear on exhalation side
how does non-invasive positive pressure vent work
uses positive pressure to keep alveoli open, improve gas exchange includes CPAP, volume limited or low limited, biPAP
