A

High flow delivery systems

20
Q

examples of high flow delivery system

A
  1. Air- Entrainment Mask
  2. Air- Entrainment Neblizer
  3. High- Flow Nasal Cannula
21
Q

DELIVERS MODERATE TO HIGH FiO2

A

Reservoir delivery system

22
Q

examples of reservoir delivery system

A

Simple mask, Reservoir Cannula, Partial re- breathing mask, Non- re- breathing mask

23
Q

Completely Enclosing the patient
from the outside environment

A

enclosure delivery system

24
Q

Enclosure delivery syste examples

A

Oxygen Tent, Oxygen Hood

25
Q

A PLASTIC DISPOSABLE DEVICE CONSISTING
OF TWO TIPS OR PRONGS 1 CM LONG
CONNECTED TO OXYGEN TUBING

A

nasal cannula

26
Q

FiO2 of nasal cannula

A

24—40% LPM

27
Q

Flow of nasal cannula

A

1⁄4 - 8Lpm ( adult)
 2 LPM ( CHILD)

28
Q

is a soft plastic tube with several small holes at the tip
that is inserted by gently advancing it along the floor of
either nasal passage and visualizing it just behind and
above the uvula.
 rarely used device

A

Nasal catheter.

29
Q

 used for limited, short-term O2 administration during
specialized procedures such as a bronchoscopy.
 It should be replaced with a new one (placed in the
opposite naris) at least every 8 hours.

A

nasal catheter

30
Q

is a thin polytetrafluoroethylene (Teflon) catheter
inserted into the trachea between the second and
third tracheal rings, secured by a chain necklace.
 Compared with a nasal cannula, a transtracheal
catheter needs approximately half of the O2 flow to
achieve a given PaO2
 however, transtracheal O2 therapy can pose serious
problems and risks and these devices are not currently
in widespread use.

A

partial rebreathing mask

34
Q

has 3 undirectional valves, to deliver 100% O2 bag should be remained inflation

  3. THE MORE AIR THEY ENTRAIN, THE HIGHER
    IS THE TOTAL OUTPUT FLOW BUT THE LOWER
    IS DELIVERED FiO2
