Q

What is the general treatment of dyspnea (difficulty breathing)?

A

Loosen restrictive clothing
semi-sitting/tripod position
O2 depending on their SpO2

17
Q

What is the treatment for hyperventilation syndrome?

A

calm down, remove from stimuli
attempt to slow down breathing
No paper bags, use cupped hands for short periods of time
if cyanotic, paresthesia, lowering LOR give O2
As stimuli to breathe is CO2, pt may stop breathing with O2 admin, prep to ventilate

18
Q

What is bronchitis?

A

excessive mucous secretions, inflammatory changes

19
Q

What is emphysema?

A

Lungs unable to effectively exchange CO2/O2
Careful with hyper-oxygenation

20
Q

What is the pathogenesis of asthma?

A

muscle contraction, inflammatory reaction, increased mucous production, increased mucous viscosity, decreased air exchange due to spasm, swelling, secretions

21
Q

What are the S/S of asthma?

A

wheeze on exhalation
difficulty breathing
chest tightness
ineffective cough
headache
tight/irritated throat
mild cyanosis

22
Q

what can a bad asthma attack lead to?

A

it can progress to respiratory arrest, “ a silent asthmatic is not a good sign”

23
Q

What does a nebulizer do?

A

changes asthma medication from a liquid to a mist, so that it can easily inhaled into lungs

24
Q

What is the peak flow in a green zone asthma plan?

A

80% or more of personal best

25
Q

What is the peak flow in a yellow zone asthma plan?

A

50-80% of best

26
Q

What is the peak flow in a red zone asthma plan?

A

less than 50% of personal best

27
Q

What is the course of action for red zone asthma?

A

Safe place/ stress free environment
position of comfort/ posture of ease
take extra puffs of reliever meds/ don’t wait
use aero-chamber for better admin
take a dose of oral steroids meds
oxygen if available
seek care at urgent care facility

911 if in red zone
>15min
cyanotic
hard to talk/walk

28
Q

What is the opioid action plan?

A

obtain info about medication that all athletes are taking
know the signs and symptoms of an opioid overdose
have a naloxone kit and pocket mask available in fanny pack
have access to BVM/AED/ assistant within 3 min

29
Q

S/S of opioid overdose?

A

unresponsive
breathing labored, snore-like, ineffective, absent
pupils constricted

30
Q

What are the proper intervention steps of an opioid overdose?

A

911/ action plan activated
BLS provided as required
SAMPLE indicates possibility of intoxication/overdose
Naloxone available and admin
Do not delay admin if available, resume BLS right away
Naloxone repeated every 3 min until responsive
Provide post intervention/recovery care
Possible relapse, should not be left alone
Transfer of care to EMS

31
Q

Which nostril should you administer naloxone in?

A

Right nostril
then left nostril when repeated

32
Q

What are the signs and symptoms of hypoxia?

A

increased respiration
increased pulse
cyanosis
changes in LOC
restlessness
chest pain

33
Q

What should you administer O2 for?

A

shortness of breath
chest pain/MI
breathing difficulties
altered levels of consciousness
hemorrhage: external/internal
shock prevention/ treatment
polytraumatized

34
Q

When should you ventilate patient with BVM or PM?

A

if respirations are <10 or >30

35
Q

What is the max duration of a D cylinder?

A

15 minutes

36
Q

What is the difference between inhalation and ventilation?

A

inhalation: patient breathing but needs supplemental O2
ventilation: patient not breathing, must be given breaths ideally with supplemental O2

37
Q

What percentage of O2 does a nasal canula provide?

A

provides atmospheric O2 21% + 4% for every liter flow so if 4l/min
21% +(4x4)= 37%

38
Q

What are the industry standard for Oxygen cylinders?

A

D size cylinder
2000 psi full tank
should have at least 800psi on standby
change cylinder at 500psi
minimum cylinder pressure 200psi

39
Q

What are the precautions during oxygen delivery?

A

do not operate around flames/sparks
do not stand cylinder upright
do not use grease/oil/ petroleum products to lubricate
check oxygen flow before placing delivery device on victim
Once tank in use keep regulator on tank at all times
