9.1 Introduction
The temperature, pulse and respiratory rate are included in measurements referred to as vital signs. Vital signs must be accurately measured because they tell us a great deal about a person’s condition. When a change from normal is seen it means the client should be observed closely. You may also be required to care for clients who require oxygen therapy. This may be a delegation of task (DOT) depending on the facility you work in.

The degree of hear or cold in an object or a human body.
The portion of the brain that maintains the body’s internal balance (homeostasis).
The beat of the heart felt at an artery as blood passes through.
The addition of oxygen to the human body.
Passageways that connect the trachea to the lungs.
Small sacs at the bottom of the lungs where oxygen and carbon dioxide exchange takes place.
Blood vessels that bring oxygen rich blood from the heart to the body cells and tissues.
A protein found in red blood cells that combines with oxygen to carry to cells and tissues of the body
A condition that affects the airways of the lungs, causing them to become narrower and making it difficult to breath.
A chronic lung disease that causes obstructed airflow from the lungs. Emphysema and chronic bronchitis contribute to COPD.
An infection of the lungs caused by viruses, bacteria or fungi.

Providing extra or additional oxygen.
A method of removing mucous from the mouth and/or lungs.
A device that takes in air from the room and filters out nitrogen
Device used for people who are able to breathe spontaneously on their own but need help in keeping their airway unobstructed.
Similar to a CPAP devise but has two pressure settings; one during inhalation and a lower setting during exhalation.
Narrowing of the blood vessels in the extremities, ie: hands and feet.
Widening of the blood vessels in the extremities, ie: hands and feet.
