What is Dyspnea?

Difficult or labored breathing accompanied by feeling short of breath.

78% nitrogen
21% oxygen
1% other gasses

4

What effect does carbon dioxide have on the blood?

Lowers pH

5

What is the primary muscle of respiration?

Diaphragm

6

What are he main accessory muscles of respiration?

Pectoralis major and minor
intercostal muscles
SCM (sternocleidomastoid)
Scalenes
Trapezius
Abdominal muscles

7

In what structure does the oxygen/CO2 exchange occur?

Alveoli

8

What is the pleural space?

The "potential" space between the plera and the chest wall.

9

What is the pleura?

The thin membrane covering the outside of the lungs and inside of the chest wall.

10

Define airway patency.

A condition in which an airway is open and unobstructed.

11

What does COPD stand for?

Chronic Obstructive Pulmonary Disease

S/S of COPD?

Patient can not exhale adequate air
Increased mucus production
Persistent Productive Cough

13

S/S of Asthma?

Sudden, recurrent bronchiolar constriction
Increased mucous production

14

What does Hyperventilation cause to occur in the blood?

Low carbon dioxide levels.

15

What is DVT?

Deep venous thrombosis which are clots that form in the legs or pelvis and travel through the heart and into the pulmonary circulation.

16

What is a pulmonary embolism?

When an embolus travels to the pulmonary artery or branch completely or partially blocking it.

17

What is anoxia?

Lack of an oxygen supply

18

WHat is a pneumothorax?

An abnormal collection of air within the pleural space.

19

What is the most common cause of upper airway obstruction?

The tongue.

20

What is wheezing?

a high-pitched respiratory sound caused by a narrowing of the tubular airways.

21

What is bradypnea?

a decreased respiration rate of less than 10rpm in adults.

22

What is crepitus?

"crackling" feel of the skin indicating air under the skin.

23

Describe how to assess lung sounds.

1. upper lobes - anterior: 1.5" below the mid-clavicle - Left than Right
2. Lower lobes - anterior: at or below the nipple line and over the anterior midaxillary line - Left than Right
3. Upper lobes - posterior: between the top of the scapula and spine 2" below the neck - Right than Left
4. Lower lobes - posterior: below the bottom of the scapula - Right than Left

24

What is the hallmark of respiratory-related emergencies?

dyspnea

25

What respiratory rate(s) indicate impending respiratory failure?

less than 6-8 or greater than 30 in an adult.

26

Describe how to assist a patient with a metered-dose inhaler.

1. PPE / Standard Precautions
2. Obtain premission
3. Verify the med is thiers, correct dose, and in date.
4. Shake, remove cap, apply spacer if there is one
5. Help patient by holding the device to thier mouth
6. encourage a deep breath and assist by depressing the top. Instruct them to hold thier breath for 10 seconds.
7. Repeat once if no improvement in 30-60 seconds according to the lable.
