20
The Respiratory System
2. Explain the structure and function of the respiratory system
Remember these points about the respiratory system:
• The epiglottis shuts off the larynx during the swallowing
process.
• The larynx enables humans to speak.
• Respiration, the body’s taking in of oxygen and removing of
carbon dioxide, involves inspiration (breathing in) and
expiration (breathing out).
20
The Respiratory System
2. Explain the structure and function of the respiratory system
Functions of the respiratory system:
• Serves as an air filter, cleaning inhaled air
• Supplies oxygen to body cells
• Removes carbon dioxide from cells
• Produces the sounds associated with speech
20
The Respiratory System
2. Explain the structure and function of the respiratory system
Normal changes of aging in the respiratory system:
• Lung strength decreases.
• Alveoli become less elastic and decrease in number.
• Airways become stiff and less elastic.
• Lung capacity decreases.
• Rib cage changes and chest muscles become weaker.
• Cough reflex becomes less effective and cough becomes
weaker.
• Oxygen in the blood decreases.
• Decreased lung capacity causes voice to weaken.

is held in place with an elastic band that slides over the head
and above the ears.

flames, which can spark and cause fire. Remove any fire hazards.
20 The Respiratory System
Handout 20-1: Oxygen Therapy Using a Humidification Device
Oxygen administration can dry out the mucous membranes of the nose and
mouth. Because of this, humidifying devices are often added to oxygen therapy
devices. The humidifying container is filled with sterile or distilled water. The
oxygen moves through the water and collects moisture before it is transferred
to the resident.
Humidification devices are commonly pre-filled devices; nurses or respiratory
therapists will replace the humidification device when its water level is low with
a new, pre-filled container. Some facilities may use humidification devices that
have to be refilled by the nurse or the respiratory therapist when the water
level becomes low. The nursing assistant’s responsibility is to observe the
humidification device and report promptly when the water level becomes low.
In addition, if the device is not bubbling, or the bubbling decreases, report this
promptly to the nurse.
Guidelines for Oxygen Therapy using a Humidifying Device
• Check the humidification device often to make sure it is bubbling. Carefully
observe the water level in the humidification device.
Notify the nurse if the following occurs:
• Water in the humidification device stops bubbling
• Decrease in bubbling
• Water level in the humidification device becomes low

6. Describe how to collect a sputum specimen
Know these points about collecting a sputum specimen:

system.

• Some facilities do not allow nursing assistants to collect
sputum specimens; always follow facility policy.
• Early morning is the best time to collect sputum.
• Resident should rinse mouth with water but not with
mouthwash before specimen collection.
Collecting a sputum specimen

and lid, completed label (labeled
with resident’s name, room
number, date, and time), tissues,
plastic bag, gloves, mask, emesis
basin
1.

Collecting a sputum specimen
5.
Put on mask and gloves.
If the resident has
known or suspected TB
or another infectious
disease, wear the proper
mask when collecting a
sputum specimen.
6.
Ask the resident to rinse
her mouth with water.
Assist as necessary.
Have her spit rinse water
in the emesis basin, if
she does not use the
sink.

7.
8.
Ask the resident to cough
deeply, so that sputum
comes up from the lungs.
To prevent the spread of
infectious material, give
the resident tissues to
cover his or her mouth.
Ask the resident to spit
the sputum into the
container.
When you have obtained a
good sample (about two
tablespoons of sputum),
cover the container
tightly. Wipe any sputum
off the outside of the
container with tissues.
Discard the tissues. Apply
the label and put the
container in the plastic
bag and seal the bag.
