Oxygen Therapy Equipment
Name one type of oxygen delivery?
Low flow, high flow and reservoir
It is used to control the flow that is delivered to a patient
Flowmeter
This gas is used to reduce the WOB in patients with severe acute asthma or upper airway obstructions until the primary problem can be resolved.
Heliox therapy
Oxygen therapy is indicated when SaO2 is below ____ and PO2 is below ______.
< 90 % , < 60 mmHg
80 - 100 %
A humidifier should be given to the patient using a nasal cannula when the flow is greater than ___ LPM.
> 4 LPM
This prevents changes in downstream resistance, or backpressure, from affecting meter accuracy.
Pressure Compensated Thorpe Tube
An inhaled gas is given for pulmonary vasodilation and used in airway obstruction. Usually given to neonates, ARDS, and adults with pulmonary HTN.
Nitric Oxide
Name one hazards of oxygen therapy
1. oxygen toxicity
2. depression of ventilation
3. Retinopathy of Prematurity
4. absorption atelectasis
5. fire hazard
What is the Liter flow range of a simple mask?
6 - 10 LPM
What is the very first procedure for delivering oxygen therapy?
Verify physician’s order
What flow meter would be most appropriate in transporting a patient when the cylinder needs to be laid flat on the floor?
bourdon gauge
In clinical practice, how is a positive identification made of the contents of a medical gas cylinder?
Reading the cylinder label
What is the desired PaO2 for a premature, a low birth weight infants, or a neonate less than 1 month old?
< 80 mmHg
What is the FiO2 of a nasal cannula on 3 LPM?
30%
This system delivers direct high-pressure oxygen through a small nozzle or jet surrounded by ports.
Air entrainment system
What is the cylinder color code for Helium?
Brown
What key property of Helium makes it useful as a therapeutic gas?
It’s low density
What percent of FiO2 can increase the risk of absorption atelectasis?
> 50 %
The venturi mask delivers ____ to ____ % of O2 depending on which connector is used...
24 - 50 %
Why do COPD patients tend to hyperventilate when given oxygen?
Due to the suppression of their hypoxic drive
Which type of safety system will prevent you from connecting an airflow meter to an oxygen station outlet?
DISS (diameter index safety system)
How should Heliox be delivered?
Non-rebreather or simple mask
What does oxygen toxicity look like in an x-ray?
patchy infiltrates in lower lung fields
How much flow/min does a bag valve (ambu bag) mask deliver?
15 LPM
