Ex 4 Flashcards
What does SPO2 measure?
It measures the percentage of Hgb saturated with Oxygen
What is pleth?
It shows on a pulse ox and measures the O2 saturation level, and PPG. It can measure the changes in the volume of arterial blood with each pulse beat
What is the normal range of SPO2
Greater than 94%
Where can you asses SPO2?
Finger, toes, foot, forehead, earlobes
What is room air?
Is a mixture id oxygen, nitrogen, and CO2
How much air does oxygen make up?
In a room is normally 21%
What do the cardiac and respiratory system work together to do in regard to oxygen ?
To supply the body with O2 necessary for carrying out respiratory and metabolic process needed to sustain life.
What affect oxygenation?
Physiological factors
Developmental factors
Lifestyle factors
Environmental factors
What is supplemental oxygen considered?
It is considered a medication
Do you need an order to administer oxygen to a patient?
Yes, an order is needed.
When should oxygen be applied to a patient?
During an acute disturbance in oxygen status-
O2 status lower than patient’s baseline
RR elevated
Shortness of breath
Accessory muscle use
Decreased mental status
Why do we not want to immediately jump to applying O2 on a patient all the time?
Because patients can get depended on it
Define Titration?
Is test used to evaluate your oxygen need at rest and during exercise.
When do you titrate oxygen?
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
What is nasal cannula?
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.
What rate is oxygen delivered in a nasal cannula ?
From 0.1 to 6L/min
What is high flow nasal cannula?
Heated, humidified oxygen through a nasal cannula at high flow rates. It is larger in diameter than a standard nasal cannula.
What concentration of O2 is administered when a patient is using high flow?
Up to 100% concentration of oxygen.
How much oxygen can a high flow nasal cannula administer?
Up to 60 L/min
When do you use a high flow nasal cannula
Used to treat acute respiratory distress patients or chronic patients who require higher flow rates.
What percentage of oxygen concentration is delivered when using a simple face mask?
40%-60% mixed with room air
How much oxygen is delivered in L-min when on simple face mask?
From 5-10L/min
What is a non-rebreather mask?
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.
What % of oxygen concentration is delivered when using NRB?
100% oxygen concentration
How much oxygen is delivered in L/min when on an NRB?
Up to 15L/min
When do you use NRB?
When patient is in respiratory distress or requires hyperoxygenation
When can you humidify oxygen?
When using a wall oxygen or oxygen concentrator, not a portable oxygen device.
How is oxygen delivered to patients?
Through wall oxygen
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 ?
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.
What must be used with a portable oxygen tank?
A regulator must be used on a portable oxygen tank
Regulator tells us how much oxygen is in the tank.
What is the dial on the LEFT used for on a portable oxygen tank ?
The dial on the left is used to titrate the amount of oxygen being delivered to the patient
Can you humidify portable oxygen ?
No, you can not humidify portable oxygen
What is an oxygen concentrator?
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)
What types of oxygen delivery methods can you humidify ?
What is a nebulizer mist treatment?
Changes liquid medicine inti fine droplets that are inhaled through a mouthpiece or a mask
What is the most common medication administered via nebulizer treatment?
Most common medication used is an adrenergic bronchodilator
How much oxygen is delivered using nebulizer mist treatment?
Up to 6-8L/min
