0

What is a normal pulse oximeter reading?

Above 94%

1

Where are stretch receptors located and what do they do?

In the walls of the lungs, prevent over expansion injuries

2

Where are irritant receptors located and what do they do?

In the walls of the bronchioles, detect the presence of abnormalities such as excessive fluids, toxic fumes, smoke

3

Where are the j receptors located and what do they do?

Near the alveoli, detect when the alveolar - capillary beds are becoming abnormally engorged with blood as a result of heart failure

4

What is wheezing and what is it associated with?

A high pitched, musical, whistling sound that is best he hard on exhalation. It is an indication of swelling and constriction of the inner lining of the bronchioles.

Asthma, emphysema, chronic bronchitis

5

What is rhonchi and what is it associated with?

Snoring or rattling noise heard upon auscultation. They indicate obstruction of the larger conducting airways by a thick mucus

Chronic bronchitis, emphysema, aspiration, pneumonia

6

What is crackles?

Aka rales - bubbly or cracking sound heard during inhalation, sounds associated with fluid that has surrounded or filled the alveoli or very small bronchioles

Pulmonary edema, pneumonia

7

Hypoxemia?

Decrease of oxygen in the blood stream typically an SpO2 reading below 94%

8

Dyspena?

Shortness of breath

9

Apnea?

Not breathing

10

Hypoxia?

Inadequate supply of oxygen to the cells and tissue

11

What is respiratory distress?

Difficulty breathing but has adequate tidal volume and respiratory rate

12

What is respiratory failure?

When either the tidal volume or respiratory rate becomes inadequate

13

What is CPAP?

Continuous positive airway pressure

14

What is respiratory arrest?

When breathing stops completely

15

What is COPD?

Chronic obstructive pulmonary disease

16

What is BiPAP?

Bilevel positive airway pressure

17

What is emphysema?

Destruction of the alveolar sacs and capillary beds

18

What is chronic bronchitis?

Inflammation, swelling and thinking of the lining of the bronchi and bronchioles and excessive mucus production

19

What is asthma?

An increased sensitivity of the lower airway to irritants and allergens causing bronchospasm

20

What is pneumonia?

Lower respiratory tract infection that causes lung inflammation and fluid or pus filled alveoli

21

What is a pulmonary embolism?

Sudden blockage of blood flow through the pulmonary artery

22

What is acute pulmonary edema?

When an excessive amount of fluid collects in the spaces between the alveoli and capillaries

23

What is a spontaneous pneumothorax

A sudden rupture of a portion of the visceral lining of the lung, not caused by trauma, that causes the lung to partially collapse

24

What is hyperventilation

Faster deeper breaths that blow off excessive amounts of carbon dioxide

25

What is epiglottis

The area around the epiglottis and the base of the tongue become infected

26

What is pertussis

Whooping cough, uncontrolled coughing

27

What is cystic fibrosis

An abnormal gene that alters the mucous gland to cause and over abundant production of mucus, which is very thick and sticky

28

What does OPQRST stand for?

O - onset, what were you doing when the symptoms started
P - provocation, what makes the pain better or worse
Q - quality, is it harder to breath in or out
R - radiation, is there pain any where else
S - severity, how bad is the pain on a scale of 1 to 10
T - time, when did difficulty start
