With low flow oxygen the rate coming from the device
answer
is lower than the patient's inspiratory flow rate/demand *Low-flow systems don't provide all the gas needed to meet the patient's total The patient also has to draw in room air
question
Low flow oxygen devices
answer
NP SM NRM Bi-flow mask
question
High flow oxygen devices provide
answer
enough air flow to meet the patient's entire inspiratory needs (above 40 LPM)
question
High flow devices can be single or
answer
double flow
question
IH requires all high flow devices to have the Oxygen flowmeter set to at least
answer
15L/min
question
High flow devices deliver
answer
fixed amounts of oxygen
question
Benefits of high flow
answer
- Consistent and predictable FiO2 - Apparatus flow exceeds the peak inspiratory flow of the client - Changing ventilatory pattern does not affect the FiO2 - Easy to meet the humidity requirements of the patient's airways
question
Use high flow devices only as long as needed because
answer
the longer they are used there is Increased risk for oxygen toxicity and infection
question
double flow system may be used when the patient needs
answer
a very high FiO2 - may need a flow rate above 15 L/min (the basic flowmeter does not go higher) *Two oxygen flowmeters deliver oxygen, one at 15 L/min and the other according to needs *The system is joined by a "100% O2 Tee", which has a port to connect a line from the second flowmeter
question
High flow mask
answer
Aerosol Mask (Venturi) Star Wars Mask Face Tent Trach Mask "T" Piece
question
Aerosol Mask (or Venturi Mask) requires
answer
15L/min *Administers a specific FiO2 (determined by air entrainment port on nebulizer) - generally used for "Precise Medium FiO2" delivery
question
Star wars mask delivers
answer
precise higher FiO2 & Generally requires double flow system
question
Face tent delivers
answer
15L/min & Imprecise FiO2 *Should not be used on patients requiring high oxygen level
question
Trach mask can be
answer
single or double flow *placed properly around the neck and tracheostomy to ensure adequate oxygen and humidification delivery
question
"T" Piece can be
answer
single or double flow *Should have a 6 inch reservoir tubing attached to the other side of the "T" *Can be used to attach to endotracheal tubes or tracheostomy tubes
question
Put an oral airways in by
answer
Lubricate the oropharyngeal airway with water-soluble jelly With the airway distal tip pointing up, open the clients mouth and insert the airway along the tongue When the distal end reaches the soft palate rotate the airway 180 degrees
question
DO NOT attach bronchodilators to a
answer
high flow device! it is ineffective *In order to effectively deliver bronchodilators to the patient you MUST use a Metered Dose Inhaler, (MDI) with an aerochamber.
question
nasal airways are used when
answer
can't get an oral airway in or may be somewhat conscious but not quite
question
measure a nasal airway tube from
answer
earlobe to tip of nose *must use lubrication when inserting
question
O2 Concentrator versus o2 tanks
answer
Oxygen tanks have a limited amount of oxygen compressed within them, inhaled by the user until it runs out. Oxygen concentrators filter (removes nitrogen and other agents to purify the air) and generate medical grade oxygen, at an unlimited supply so long as the battery that powers this mechanism has life.
question
PSI
answer
what is left in the tank multiplied by the conversion factor divided by the L/min client requires
question
How do you decide whether to increase or decrease the amount of oxygen administered?
answer
Based on patient condition Oxygen saturation Hemoglobin level
question
Low flow we document in
answer
L/min
question
High flow we document in
answer
percentage
question
for oral airways do NOT
answer
tape airway in place
question
OPTIFLOW/Airvo OXYGEN THERAPY provides
answer
heated and humidified gas at 37 degrees at both low and high flows through a nasal, mask, or tracheostomy interface at a flow range of 10 to 60 L/min and an FiO2 range of 0.28 to 1.0 (Optiflow); 2 to 60 L/min and an FiO2 range of 0.21 to 1.0 (Airvo 2)
question
Optiflow/Airvo is a high flow oxygen delivery system used for
answer
clients with profound hypoxemia and/or mucocilitary clearance difficulties
question
can't transport pts if they are on
answer
optiflow *can't take the wall with you Technically you can transport pts on airvo because it can be used with an oxygen tank
question
when titrating a client off of a high flow nebulizer you should decrease in increments of
answer
5-10%
question
when collecting a sputum sample the client should cough up
answer
15-30ml of sputum
question
nebulizer tubing and mask/NP should be changed every
answer
7d and PRN
