is a battery- or electric-operated device with a sensor probe that is attached

securely to the client’s fingertip, toe, bridge of nose, earlobe, or forehead with a clip or band.

A pulse oximeter measures arterial oxygen saturation (SaO₂) via a wave of infrared light that

measures light absorption by

oxygenated and deoxygenated hemoglobin

in arterial blood.

SaO₂ and SpO₂are used interchangeably

The percentage of supplemental oxygen delivered to the client is expressed as

the

fraction of inspired oxygen

(FiO₂)

What signs and symptoms indicate that

oxygen saturation should be monitored:

Wheezing

Coughing

Cyanosis

Increased work of breathing 

Acceptable levels for SaO₂

may range from 

hypothermia, poor peripheral blood flow,

too much light (sun, infrared lamps), low hemoglobin levels, movement, edema, and

nail polish

It delivers an FiO₂

of 24% to 44% at a

flow rate of

1 to 6 L/min.

Nasal cannula

(a length of tubing with two small prongs for

insertion into the nares)

It delivers an FiO₂

of 40% to 60% at

flow rates of 5 to 8

L/min.

Simple face mask

(covers the client’s nose and mouth)

It delivers an FiO₂ of

60% to 75% at flow

rates of 6 to 11 L/

min.

Partial rebreather mask

(covers the client’s nose and mouth)

It delivers an FiO₂ of 80% to 95% at

flow rates of 10 to 15 L/min to keep the

reservoir bag 2/3 full during inspiration

and expiration.

Nonrebreather mask

(covers the client’s nose and mouth)

It delivers an FiO₂ of 24% to 55% at flow

rates of 2 to 10 L/min via different

size adaptors.

Venturi mask

(covers the client’s nose and mouth)

• They deliver an FiO₂ of 24% to 100% at

flow rates of at least 10 L/min.

• They provide high humidification with

oxygen delivery.

________ is combustible, have the client wear a _____ gown because synthetic or wool fabrics can

generate static electricity.
