17
Q

Describe costal respiration:

A
  • the function of the diaphragm is lost (abdominal pain caused by inflammation)
  • increased abdominal pressure, (pregnancy, meteorism, ascites)
  • narrowed upper airways, compression of the lung
18
Q

Describe abdominal respiration:

A

-painy chest diseases and paralysis of intercostal muscles

19
Q

How can we describe the respiratory rhythm?

A

-Held inspiration
-Held expiration
-Shorter inspiration or expiration
-Asymmetric breathing
Intermittent inspiration

20
Q

What can cause held inspiration?

A
  • narrowed upper airway’s

- higher abdominal pressure (pregnancy, ascites, meteorism)

21
Q

What can cause held expiration?

A
  • decreased lung elasticity

- microbronchitis

22
Q

What can cause shorter inspiration or expiration?

A

-inhibition about pain

23
Q

What can cause asymmetric breathing?

A
  • one main bronchus obstruction

- pain in one chest

24
Q

What can cause intermittent inspiration?

A
  • normally during excitement, long exhausting work

- abnormally: at painy chest disorder

25
Q

How should normal respiratory depth be like?

A

medium deep

26
Q

How do you describe abnormal respiratory depth?

A
  • Shallow (superficial) respiration

- Deep respiration

27
Q

Describe shallow respiration?

A
  • cases of severe dyspnea
  • painful diaphragm and chest diseases
  • respiratory center damage
28
Q

Describe deep respiration?

A
  • after fast movement
  • at hypoxia
  • may the characteristic sign of dyspnea
29
Q

Describe dyspnea:

A

The dyspnea caused by difficulties of respiration (compression, obstruction of
the air passages, decreased lung compliance). During resting or better at
works the muscles working in respiration seem to do their work forcedly

30
Q

Types of dyspnea?

A
  1. Inspiratory dyspnea
  2. Expiratory dyspnea
  3. Mixed dyspnea
31
Q

What can be the cause of INSPIRATORY dysnea?

A 
-narrowed upper airways (stridor)
(laryngeal edema, laryngeal paralysis, stenotic nares, etc)
-pneumothorax
-pleural effusions
-diffuse pneumonia
32
Q

What are the signs of INSPIRATORY dyspnea?

A

Prolonged and labored inspiration!
Inspiratory phase is longer, extension of the head and neck, nostril
dilatation, labial respiration, spreading of the scapules,exaggerated
intercostal activity, slack or sunken flanks and sagging belly

33
Q

What can be the cause of EXPIRATORY dysnea?

A
  • compression or obstruction of lower air passages
  • microbronchitis
  • (pulmonary emphysema)
  • fibrous pleuritis
  • rarely neoplasms in larynx and pharynx
34
Q

What are the signs of EXPIRATORY dyspnea?

A

prolonged and labored exspiration
Expiratory phase is longer, the work of abdominal muscles is more
severe, extension of the head and neck, thorax very fasten collapsed
during expiration. Expiratory dyspnea is abdominal, duplicate or
strongly held

35
Q

What can be the cause of MIXED dysnea?

A
  • decreased compliance
  • pulmonary edema
  • pulmonary emphysema
  • neoplasma
  • compressed diaphragm
36
Q

What are the signs of MIXED dyspnea?

A

Forced inspiration and expiration

37
Q

Paradoxical breathing: normal respiration

A

both the abdomen and chest move in and out together,
allowing maximum expansion of the lungs. The diaphragm normally moves
downwards during inspiration and upwards during expiration

38
Q

Paradoxical breathing: Paradoxical respiration

A

the diaphragm moves opposite to the normal directions

of its movements..

39
Q

When palpating the thorax what do you check?

A
  • Temperature
  • Fremitus pectoralis
  • Painfullness
  • Deformities
40
Q

When can we find fremitus pectoralis?

A

we can find it during dry pleurisy, bronchitis, fibrinous pericarditis, stenotic
cardial valves or vave insufficiency
