Partial rebreather mask - ✔covers the client's nose and mouth
Partial rebreather mask FiO2 - ✔40%-70% at flow rates of 6 to 10 L/min
Partial rebreather mask advantages - ✔The mask has a reservoir bag attached with no
valve, which allows the client to rebreathe up to 1/3 of exhaled air together with room air
Partial rebreather mask disadvantages - ✔Complete deflation of the reservoir bag
during inspiration causes CO2 buildup
The FiO2 varies with the client's breathing pattern
Clients who have anxiety or claustrophobia do not tolerate it well
Eating, drinking, and talking are impaired
Partial rebreather mask nursing actions - ✔Keep the reservoir bag from deflating by
adjusting the oxygen flow rate to keep the reservoir bag 1/3 to 1/2 full on inspiration
Assess proper fit to ensure a secure seal over nose and mouth. Assess for skin
breakdown beneath the edges of the mask and bridge of the nose.
Make sure the client uses a nasal cannula during meals.
Use with caution for clients who have a high risk of aspiration or airway obstruction.
Nonrebreather mask - ✔Covers the client's nose and mouth
,Nonrebreather mask FiO2 - ✔60%-100% at flow rates of 10 to 15 L/min to keep the
reservoir bag 2/3 full during inspiration and expiration
Nonrebreather mask advantages - ✔It delivers the highest O2 concentration possible
(except for intubation)
A one-way valve situated between the mask and reservoir allows the client to inhale maximum
O2 from the reservoir bag. The two exhalation ports have flaps covering them that prevent
room air from entering the mask.
Nonrebreather mask disadvantages - ✔The valve and flap on the mask must be intact
and functional during each breath.
It is poorly tolerated by clients who have anxiety or claustrophobia.
Eating, drinking, and talking are impaired.
,Use with caution for clients who have a high risk of aspiration or airway obstruction.
Nonrebreather mask nursing actions - ✔Perform an hourly assessment of the valve and flap.
Assess proper fit to ensure a secure seal over the nose and mouth. Assess for skin
breakdown beneath the edges of the mask and bridge of nose.
Make sure the client uses a nasal cannula during meals.
Venturi mask - ✔Covers the client's nose and mouth
Venturi mask FiO2 - ✔24%-60% at flow rates of 4 to 12 L/min via different size
adapters, which allows specific amounts of air to mix with oxygen
Venturi mask advantages - ✔It delivers the most precise oxygen
concentration Humidification is not required
Best for clients who have chronic lung disease
Venturi mask disadvantages - ✔Use is expensive
Eating, drinking, and talking are impaired
Venturi mask nursing actions - ✔Assess frequently to ensure an accurate flow rate.
Assess proper fit to ensure a secure seal over the nose and mouth. Assess for skin
breakdown beneath the edges fo the mask particularly on the nares.
Make sure the tubing is free of kinks.
Ensure that the client wears a nasal cannula during meals.
Aerosol mask - ✔Face tent: fits loosely around he face and neck
Tracheostomy collar: a small mask that covers the surgically created opening of the trachea
, Aerosol mask FiO2 - ✔24%-100% at flow rates of at least 10 L/min
Provides high humidification with oxygen delivery
Aerosol mask advantages - ✔Use with clients who do not tolerate masks well.
useful for clients who have facial trauma, burns, and thick secretions
Aerosol mask nursing actions - ✔Empty condensation from the tubing often
Ensure adequate water in the humidification canister
Ensure that the aerosol mist leaves from the vents during inspiration and expiration
Make sure the tubing does not pull on the tracheostomy
Oxygen toxicity - ✔Can result from high concentrations fo oxygen (typically greater than
50%), long durations of oxygen therapy (typically more than 24 to 48 hr), and the severity of
lung disease
Oxygen toxicity nursing actions - ✔Use the lowest level of oxygen necessary to maintain
an adequate SpO2
Monitor ABGs and notify the provider if SpO2 levels are outside the expected reference range.
Decrease the FiO2 as the client's SpO2 improves
Oxygen-induced hypoventilation - ✔Clients who have conditions that cause
alveolar hypoventilation can be sensitive to the administration of oxygen
