Nursing Considerations
100

Low oxygen levels within the blood

Hypoxemia

100

Pressure in lungs during inspiration

Inspiratory pressure

100

How this amount in the blood is determined

ABG - arterial blood gas

100

6-10 LPM and FiO2 35-50%

Simple Mask (SM)

100

Humidification must be used at this level or greater

4 L

200

Low O2 levels in the tissues

Hypoxia

200

Amount of air left in lungs at expiration

Expiratory pressure

200

Positive _______ pressure decreases CO2

expiratory

200

10-15 LPM and FiO2 30-40%

Face Tent (FT)

200

Used most often for O2 administration and for 1-4 LPM

Nasal cannula

300

Some conditions that cause hypoxemia

COPD, asthma, PNA

300

Volume of air inspired and expired with each breath

Tidal volume

300

Decrease in __ _____ may increase build up of CO2

lung compliance

300

Mixes oxygen and ambient air to achieve desired FiO2 (24-60%) at a rate ranging from 5-15 LPM

Venturi Mask (VM) - has different colored valves specific for desired flow and FiO2

300
The intervention the RN would take for a client with an O2 sat of 99% that is not on home O2 therapy

Remove O2 and continue to monitor; inform MD

400

Contributing factors to hypoxemia

smoking, aging, high altitude

400

Average tidal volume for adult

400 - 500 mL
400

This mask allows CO2 to be exhaled freely

Nonrebreather (NRB)

400

Inflated bag with 100% oxygen, but not often used because the reservoir mixes O2 and exhaled air

Partial Rebreather (PR)

400

These should be stored in a cool, dry place and handled with a designated hand truck

Portable O2 tank 

500

Signs of hypoxia

cyanosis, confusion, tachycardia, difficulty breathing

500

Percentage of oxygen in blood at capillary level

O2 saturation

500

Therapy for decreased lung compliance by administering O2 and decreasing CO2

Bipap therapy
500

Ambient air cannot enter reservoir but exhaled air can escape

Nonrebreather Mask (NRB)

500

Guidelines including "do not smoke in the home", "keep at least 10 feet away from heat sources", and "ensure smoke and carbon dioxide alarms are working properly" are examples of this.
