Q 
Types of inhalers and when taken
Controller med?
Combination inhaler?
Anticholinergics?
Rescue med?
A

Controller med: taken daily, corticosteroids

Combination inhalers: taken daily, contain inhaled corticosteroid plus long acting beta agonist

Anticholinergics: maintenance therapy, helps open airways

Rescue med: short acting beta agonists; quickly relax/open airways, used during flare or before exercise

17
Q

Oxygen safety?

A

Start/adjust per Dr orders
Place “oxygen in use” sign
No smoking
Store cylinders upright in holders
Check O2 level prior to transferring patient
Monitor electrical equipment for integrity/ground plugs
Avoid petroleum and aerosol products containing acetone

18

A

6-12 Liters
35-50% FiO2
Humidified

20
Q

Venturi Mask % and liters

A

4 Liters: 24-28%
8 Liters: 35-40%
12 Liters: 50%

21
Q

NonRebreather Mask % and liters

A

Bag must be inflated at all times

22
Q

Simple Mask
Advantage?
Disadvantages?

A

Advantage:
humidifies O2

Disadvantage:
O2 level difficult to estimate
requires high flow O2 to prevent CO2 rebreathing
hot/confining
interferes with easting/drinking/talking
condensation can irritate skin
23
Q

Nasal Cannula
Advantages?
Disadvantages?

A

Advantage
most comfortable
can eat/drink/talk
can continue activity

Disadvantage:
easily dislodged
drying to mucous membranes
can't use with nasal obstruction
can't use with mouth breathing
can cause skin irritation (monitor ears, nares, cheeks)
24
Q

Venturi Mask
Advantages?
Disadvantage?

A

Advantage:
specific oxygen setting (COPD pt)
exhaled ports keep CO2 build up to min

Disadvantage:
specific O2 flow needed to delivered specific O2 concentration
hot/confining
interferes with easting/drinking/talking
condensation can irritate skin
25
Q

NonRebreather Mask
Advantages?
Disadvantages?

A

Advantages:
highest noninvasive O2 delivery
respiratory distress
extubated ventilator pt

Disadvantage:
reservoir bag must stay inflated
hot/confining
interferes with easting/drinking/talking
