Q

When should oxygen be applied to a patient?

A

During an acute disturbance in oxygen status-
O2 status lower than patient’s baseline

Q

When do you titrate oxygen?

A

Based on the patient s/s-
If increased s/s have not improved and the patient is requiring more O2
OR
Decreased if attempting to wean off of the O2 to determine if the patient can tolerate lower levels

Q

What is nasal cannula?

A

This device consists of a lightweight tube which on one end splits into two prongs
And tubing goes over and behind the ears, and wraps around the front of the neck.

16
Q

What rate is oxygen delivered in a nasal cannula ?

A

From 0.1 to 6L/min

17
Q

What is high flow nasal cannula?

A

Heated, humidified oxygen through a nasal cannula at high flow rates. It is larger in diameter than a standard nasal cannula.

18
Q

What concentration of O2 is administered when a patient is using high flow?

A

Up to 100% concentration of oxygen.

19
Q

How much oxygen can a high flow nasal cannula administer?

A

Up to 60 L/min

20
Q

When do you use a high flow nasal cannula

A

Used to treat acute respiratory distress patients or chronic patients who require higher flow rates.

21
Q

What percentage of oxygen concentration is delivered when using a simple face mask?

A

40%-60% mixed with room air

22
Q

How much oxygen is delivered in L-min when on simple face mask?

A

From 5-10L/min

23
Q

What is a non-rebreather mask?

A

It is a simple mask with a reservoir bag attached to allow continuous inhalation of oxygen, and allowing CO2 to exist. It has one way valve.

24
Q

What % of oxygen concentration is delivered when using NRB?

A

100% oxygen concentration

25
Q

How much oxygen is delivered in L/min when on an NRB?

A

Up to 15L/min

26
Q

When do you use NRB?

A

When patient is in respiratory distress or requires hyperoxygenation

27
Q

When can you humidify oxygen?

A

When using a wall oxygen or oxygen concentrator, not a portable oxygen device.

28
Q

How is oxygen delivered to patients?

A

Through wall oxygen

29
Q

What are the key points of using wall oxygen?
A- where is it connected to?
B- how long does it last?
C- where is it seen mainly?
D- how do you titrate oxygen in wall oxygen ?

A

Connected to main source of O2 in the building
Never runs out
It is seen mainly in hospitals or some home facilities
Titrate by using the dial & floating ball to titrate the amount of oxygen delivered to patient.

30
Q

What must be used with a portable oxygen tank?

A

A regulator must be used on a portable oxygen tank
Regulator tells us how much oxygen is in the tank.

31
Q

What is the dial on the LEFT used for on a portable oxygen tank ?

A

The dial on the left is used to titrate the amount of oxygen being delivered to the patient

32
Q

Can you humidify portable oxygen ?

A

No, you can not humidify portable oxygen

33
Q

What is an oxygen concentrator?

A

Is a machine that pulls room air(contain Oxygen ) into the device, then purify the oxygen and removes the other parts of room air (nitrogen)

34
Q

What types of oxygen delivery methods can you humidify ?

A
35
Q

What is a nebulizer mist treatment?

A

Changes liquid medicine inti fine droplets that are inhaled through a mouthpiece or a mask

36
Q

What is the most common medication administered via nebulizer treatment?

A

Most common medication used is an adrenergic bronchodilator

37
Q

How much oxygen is delivered using nebulizer mist treatment?

A

Up to 6-8L/min
