1

Define respiration.

The act of breathing; the exchange of oxygen and carbon dioxide that takes place in the lungs.

2

Define respiratory compromise.

A general term used to describe when a patient is not breathing adequately.

3

Define respiratory distress.

It refers to breathing that becomes difficult or labored.

4

Define hypoxia.

A condition in which there is an insufficient level of oxygen in the blood and tissues.

5

Define respiratory arrest.

The absence of breathing.

6

What does arrest mean in medical terms?

Absent

7

Define apnea.

The absence of breath

8

Define cardiac arrest.

The absence of a heartbeat

9

Define agonal respirations.

Respirations less than six (6) breaths per minute - an abnormal breathing pattern characterized by slow, shallow breaths that typically occur following cardiac arrest (makes a snoring sound).

10

What is normal for adult breaths per minute?

12 to 20 breaths per minute is normal.

11

Breathing is automatic, true or false?

True

12

Define clinical death.

The moment when breathing and heart actions stop.

13

Upon clinical death how long does it take for oxygen to start depleting and cells begin to die?

4 to 6 minutes

14

Define biological death.

Biological death occurs approximately 4 to 6 minutes after onset of clinical death and results when there is an excessive amount of brain cell death.

15

What is the most critical timeframe for the patient to receive CPR?

At the onset of clinical death through up to the first 6 minutes.

16

How long does it take before irreversible death may occur in a patient with no oxygen.

10 minutes

17

Can clinical death be reversed?

Yes

18

Can biological death be reversed?

No

19

How long after clinical death does biological death happen?

10 minutes

20

Define diaphragm.

The dome shaped muscle that separates the chest and abdominal cavities. It is the major muscle used in breathing.

21

Define inhalation.

The process of breathing in a.k.a. inspiration.

22

Define inspiration.

Refers to the process of breathing in.

23

Define cyanosis.

Bluish discoloration of the skin and mucous membranes; a sign that body tissues are not receiving enough oxygen.

24

Define pharynx.

The throat

25

Define epiglottis.

A flap of Cartlidge and other tissues located above the larynx. It helps to close off the airway when the person swallows.

26

Find larynx.

The section of the airway between the throat and the trachea that contains the vocal chords. It is also called the voice box.

27

Define trachea.

The windpipe

28

What are the nine (9) components of the respiratory system anatomy?

1. Nose
2. Mouth
3. Throat (pharynx)
4. Epiglottis
5. Trachea
6. Larynx
7. Bronchial tree
8. Lungs
9. Alveoli

29

Describe the respiratory cycle.

When the breathing muscles contract and enlarge the chest cavity, air flows through the mouth and nose, into the throat, passed the epiglottis, and into the trachea. Air then flows into the left and right main stem bronchi and then through the smaller bronchioles to the clusters of alveoli. The alveoli are surrounded by tiny blood vessels called capillaries. It is here in the alveoli that oxygen and carbon dioxide exchange takes place. Oxygen travels through the walls of the alveoli and into the blood, which delivers it to the cells. Carbon dioxide travels from the blood through the alveoli walls, where it is eliminated when we exhale.

30

Labored breathing is always a sign of a partial airway obstruction. true or false?

True
