AdministrationIntroduction
- Slide 4
- Key Concepts Every cell in the body needs oxygen (O 2 ) to live
In a medical emergency the body may inspire (inhale) or deliver
lower levels of oxygen Hypoxia (inadequate O 2 ) leads to organ and
brain damage Providing supplemental oxygen during an emergency may
delay damage to vital organs Emergency Oxygen
Administration4Introduction
- Slide 5
- The Air We Breathe Not made of 100% oxygen Oxygen = 0 2 Made of
several different gasses 21% oxygen 78% nitrogen 1% other elements
The body only uses about 5% of inhaled oxygen in atmosphere 16%
oxygen in our exhaled air Enough to keep someone alive w/ rescue
breaths for a short time Emergency Oxygen
AdministrationIntroduction5 O 2 Molecules!
- Slide 6
- Perfusion Oxygen perfusion is when cells receive oxygen-rich
blood Depending on condition or emergency, the victim may be able
to breathe but cant perfuse oxygen Emergency oxygen is a higher
concentration of oxygen than the air we breathe Emergency oxygen
can increase oxygen concentrations in the lungs, which may allow
more oxygen to be absorbed (perfused) into the bloodstream

- RESPIRATION & LUNG FUNCTION Respiration: The exchange of
carbon dioxide for oxygen Emergency Oxygen Administration10
- Slide 11
- Respiration & Ventilation Respiration Exchange of carbon
dioxide (CO 2 ), the waste product from breathing, with fresh air
from the atmosphere Ventilation Moving air in and out of the lungs
for respiration Alveoli Where the exchange of O 2 and CO 2 is
accomplished Small air sacs in the lower lobes of right and left
lungs Shaped like miniature broccoli stems Intertwined with
capillaries Exchange of O 2 and CO 2 occurs through fenestrations
(tiny holes) along the alveoli and capillary beds Emergency Oxygen

- Emergency Oxygen is a Compressed Gas Classified as a drug
Regulated by the FDA 100% pure oxygen stored in a cylinder
Categorized as either Medical Oxygen or Emergency Oxygen Rescuers
must be trained in use and storage of oxygen Emergency Oxygen
AdministrationWhat is Emergency Oxygen15
- Slide 16
- Medical vs. Emergency Oxygen Concentrations are same for each
100% oxygen Differentiated by how each is used Oxygen delivery or
flow rate is calculated by the number of liters delivered per
minute (LPM) Medical oxygen Requires prescription for use Delivery
rate of less than 6 LPM OR Duration of less than 15 minutes
Emergency oxygen Training for rescuers required, prescription not
required At least 6 LPM for 15 minutes or longer Clearly labeled as
emergency oxygen Emergency Oxygen AdministrationWhat is Emergency

valve inside mask to speed up filling reservoir Place over the
patient's mouth and nose Emergency Oxygen AdministrationDelivery
Devices39
- Slide 40
- Tolerating a Non-Rebreather Mask The mask will completely cover
the mouth & nose, which can make it intolerable for some
Patient may complain that flow of O 2 is restricted, even though
they are getting more than 90% O 2 Ensure flow rate is at least 15
LPM, oxygen is flowing and the reservoir is inflated Rescuers may
have to coach a patient Help get used to mask Reassure they are
getting more oxygen than normal Emergency Oxygen
AdministrationDelivery Devices40

through nose
- Slide 43
- Bag Mask Emergency Oxygen AdministrationDelivery Devices43 Also
known as Bag Valve Mask or BVM Used for rescue breathing/CPR
Delivers nearly 100% oxygen May reduce exposure to pathogens
Requires additional training to be used effectively
- Slide 44
- Using a Bag Mask May be used with or without oxygen Science
does not support or refute the use of oxygen during resuscitation
Risks related to over-exposure to oxygen are low; it is reasonable
to use oxygen during resuscitation Never delay resuscitation
efforts in order to use emergency oxygen The use of emergency
oxygen does not change how rescue breaths are delivered with a bag
mask Emergency Oxygen AdministrationDelivery Devices44
- Slide 45

- RISKS ASSOCIATED W/ OXYGEN DELIVERY Emergency Oxygen
Administration53
- Slide 54
- Risks of Oxygen Delivery Potential risks related to oxygen
delivery Oxygen Toxicity Retinopathy of Prematurity Denitrogenation
COPD and the Hypoxic Drive Emergency Oxygen AdministrationOxygen
Risks54
- Slide 55
- Oxygen Toxicity Occurs when there is too much oxygen in the
blood Caused by prolonged exposure to high concentrations of oxygen
Usually after 24 hours or more Emergency oxygen is usually not
administered long enough to cause oxygen toxicity, and is generally
not a concern in the field Signs/symptoms: visual changes, ringing
in ears, twitching, irritability, dizziness, seizure Emergency
Oxygen AdministrationOxygen Risks55
- Slide 56
- Retinopathy of Prematurity Retinopathy of prematurity only
occurs in premature infants The retinas are immature before 34
weeks gestation, and can be damaged by high concentrations of
oxygen It is not a problem associated with the normal use of
emergency oxygen Emergency Oxygen AdministrationOxygen Risks56
- Slide 57
- Denitrogenation Also known as Absorption Atelectasis Occurs
when naturally-occurring nitrogen in the lungs is replaced with
oxygen from over-saturation Oxygen shares alveolar space with
nitrogen If the nitrogen is washed out by too much O 2, the alveoli
collapse Can severely impair lung function (process known as
atelectasis) Not usually associated with emergency oxygen delivery
because exposure to high concentrations of oxygen is limited to a
relatively short period Emergency Oxygen AdministrationOxygen
Risks57
- Slide 58
- COPD and Hypoxic Drive Hypoxic drive is condition associated w/
COPD Normally, body stimulated to breathe when too much carbon
dioxide is detected COPD patients stimulated to breathe by lower O
2 levels and to NOT breathe with higher O 2 levels Concern that
emergency oxygen can eliminate the hypoxic drive of a COPD patient,
causing person to stop breathing General rule: Always give
emergency O 2 if indicated (even if history of COPD) Difficulty
breathing may be related to a condition other than COPD Hypoxic
drive is rare; do not withhold emergency O 2 Emergency Oxygen
AdministrationOxygen Risks58
- Slide 59
- GENERAL GUIDELINES FOR EMERGENCY OXYGEN DELIVERY Emergency
Oxygen Administration59
- Slide 60
- General Guidelines Guidelines for the delivery of emergency O 2
include the following: Monitor delivery Understand the use of
oxygen in resuscitation Train emergency responders Follow federal,
state and local regulations Emergency Oxygen
AdministrationGuidelines for Oxygen Delivery60
- Slide 61
- Monitor Oxygen Delivery Emergency oxygen delivery should be
based on target saturation levels, not fixed flow rates Using
oxygen to treat breathlessness rather than low oxygen saturation
has not been shown to help feeling of breathlessness Pulse oximetry
is recommended to monitor blood-oxygen levels When a pulse oximeter
is available, titrate oxygen delivery to the lowest effective
level. Emergency Oxygen AdministrationGuidelines for Oxygen
Delivery61
- Slide 62
- Emergency Oxygen & Resuscitation Science is inconclusive
about the use of emergency oxygen during resuscitation Studies show
emergency oxygen during resuscitation: Increases amount of oxygen
in the blood Has little risk of complications Ensure resuscitation
efforts are NEVER DELAYED in order to use emergency oxygen After a
return of spontaneous circulation (ROSC) Titrate delivery to the
lowest level possible Maintain an SpO 2 of 94%-99% Emergency Oxygen
AdministrationGuidelines for Oxygen Delivery62
- Slide 63
- Training for Emergency O 2 Use The Organizations medical
authority should review and approve use and training methods before
equipping staff Train at least one staff member in use of emergency
oxygen at all times during business hours Training should be
certification level from a nationally-recognized organization
Training should incorporate any local guidelines that may differ
from this training Emergency Oxygen AdministrationGuidelines for
Oxygen Delivery63

- OXYGEN SAFETY Emergency Oxygen Administration64
- Slide 65
- Key Concepts Oxygen is very reactive and can create a dangerous
situation by making items more flammable When the oxygen level is
increased, it is easier to start a fire and very difficult to put
it out Take precautions when Using emergency oxygen w/
defibrillator Storing and handling cylinders Emergency Oxygen
AdministrationOxygen Safety65
- Slide 66
- Using Oxygen w/ a Defibrillator 100% oxygen is combustible Good
chest-to-pad contact Eliminates oxygen pockets between pad and skin
Reduces risk for AED use w/ oxygen Move mask at least 3 feet from
victim before shocking Loudly state Oxygen clear Only shock when
rescuers & oxygen are clear Emergency Oxygen
AdministrationOxygen Safety66
- Slide 67
- Cylinder Storage Store cylinders Upright Secured to prevent
falling Avoid storing different types of compressed gasses in the
same area Store in a well-ventilated area Do not subject cylinders
to temperatures greater than 125 o F, prolonged exposure to direct
sunlight, or exposure to other heat sources (e.g. radiator, space
heater) Emergency Oxygen AdministrationOxygen Safety67
- Slide 68
- Cylinder Maintenance Regularly inspect equipment and document
inspections according to national and local guidelines and
manufacturer specifications Ensure labels and signs are in
compliance w/ federal OSHA, state and local regulations Do not use
a cylinder that appears damaged Keep oxygen equipment clean. Dirt
and debris can be a fire hazard Use a pressure gauge to check
contents; do not rely solely on a tagging system (Full, In-Use,
Empty) Emergency Oxygen AdministrationOxygen Safety68
- Slide 69
- Cylinder Handling Do not slide, drag or roll cylinders Do not
use oil or grease on oxygen equipment When on scene, lay the oxygen
cylinder on the floor so it does not get knocked over accidentally
If transporting the cylinder with the patient, secure it to the
cot, stretcher or gurney so that it does not slip or get knocked
off Emergency Oxygen AdministrationOxygen Safety69

- Storage Emergency Oxygen AdministrationOxygen Safety70 What is
wrong with this picture?
- Slide 71
- Oxygen is Combustible 100% oxygen is highly reactive, and can
cause other materials to catch on fire Keep away from heat sources
and flammable items Avoid alcohol, aerosol sprays, solvents,
perfumes and petroleum products Never combine oxygen with an
ignition source (e.g. cigarette) Emergency Oxygen
