Q

When could an individual start to feel the symptoms pulmonary oxygen toxicity?

A
  • Whenever the oxygen partial pressure exceeds 0.5 ata.
  • A 12 hour exposure to a partial pressure of 1 ata will produce mild symptoms and measurable decreases in lung function.
  • The same effect will occur with a 4 hour exposure at a partial pressure of 2 ata.

Q

What is systolic and diastolic blood pressure?

A
  • Systolic: pressure created in the arteries when the heart pumps blood into circulation

Q

OPA/NPA

A
  • measure from tip of nose to tip of ear lobe
  • lube NPA with water soliable lube
  • insert NPA right nostril with bevel towards the septum

-if you have to insert left nostril face the bevel towards the septum and half way through rotate 180 to resume alignment.

26
Q

IV flow rate

A

75 to 100 cc/hour

27
Q

Chamber temp 95-104 what TT and how long can you do them

A
  • 5
  • 9

2 HOURS

28
Q

CNS O2 toxictiy when PP exceeds what ATA for wet and dry?

A

Wet- 1.3 ATA

Dry- 2.4 ATA

29
Q

Pulmonary Overinflation Syndromes (POIS)

A

Leaking of gas into the pulmo­nary interstitial tissue

30
Q

Explain the recovery position?

A

Lie patient down in a fetal position on their left side with head tilted up. Lay on left side because the right lung has 3 lobes vs 2 on the left and also to keep from aspiration from stomach. Keep warm and comfortable position.

31
Q

symptoms of SHOCK

A
  • Decrease in blood pressure
  • Rapid weak heart rate
  • profuse sweating
  • light headed
  • Nausea
  • Cyanosis
  • Confusion
  • Clammy Skin
32
Q

Barotrauma

A

damage to body tissues caused by a difference in pressure

34
Q

when can you stop CPR?

A
  • Signs of life
  • Pronounced dead by a doctor
  • qualified person relieves you/ higher care
  • AED shock
35
Q

What are four means of keeping air way open?

A
  • Opa oropharyngeal airway #4 and #5
  • Npa nasal airways #32f and #34f
  • Cricothyrotomy kit
  • Alternative Emergency airway device

Dive manual 17-8/17-9 table

36
Q

symptoms of subcutaneous emphysema

A
  • fullness in throat
  • change in voice
  • Rice Krispies (crepitus)
  • difficulty swallowing
37
Q

Partial pressure of oxygen below what causes the onset of hypoxia?

38
Q

tourniquet/ hemorrhage control

A
  • direct pressure and pressure points first
  • use tourniquet as a last resort
  • put on high and tight
  • mark T on head and the time you put it on
  • do not take off or loosen
  • seek higher medical care and notify that you put on a tourniquet
39
Q

What are the shockable rhythms an AED will read?

A

Ventricular fibrillation

Pulsesless ventricular tachycardia

40
Q

Subcutaneous Emphysema

A

when that gas subsequently migrates into the subcutaneous tissues of the neck

41
Q

What is the first step in pulmonary over-inflation?

A

Interstitial Emphysema:

-rupture of the alveolus with a collection of air in the lung tissues

42
Q

Explain what an IT is looking for with the cranial Vagus Nerve? What is its job?

A

The rise and fall of the soft pallet. Also known as cranial nerve X, the vagus forms part of the involuntary nervous system and commands unconscious body procedures, such as keeping the heart rate constant and controlling food digestion.
