Q

Traumatic: blunt trauma or penetrating trauma that disrupts the parietal or visceral pleura eg. gunshot, arrow, stabbing, rib fracture, surgery.
Pathologic: rupture of pleural layers or alveoli eg. tumors, abscess, COPD, CF, TB, and air enters the pleural space via distended/damaged/ruptured alveoli.
Iatrogenic: secondary to diagnostic or therapeutic medical intervention.
Idiopathic: no preceding trauma and no underlying lung pathology - not uncommon in tall, thin, athletic adolescents, and smokers.

Q
  • treatment is directed to the underlying cause and suppressing the inflammation
  • pain medications
  • laying on the affected side to limit breathing movement may reduce the stretching of the pleura and therefore the pain, when pleuritis is acute

20
Q

Can result in reduced ventilation and oxygenation of lung tissue (poor perfusion).

A

Atelectasis

21
Q

May also interfere with secretion clearance from the lungs, leading to an increased risk of infection.

A

Atelectasis

22
Q

acute pneumonia, bronchiectasis, respiratory failure, sepsis, pleural effusion and empyema.

A

COMPLICATIONS due to Alectasis

23
Q

a collection or gathering of pus within a naturally existing anatomical cavity e.g.: pleural cavity (as differentiated from an abscess, which is a collection of pus in a newly formed cavity or wound). Or as Eeeen says, “a Boston cream lung”

A

Empyema

24
Q

1 of 3 Sources of Atelectasis

When there is an obstruction that blocks an airway between the alveoli and the trachea. Air trapped distal to obstruction is absorbed, leading to airway/lung collapse.

A

Obstruction (resorption)

25
Q

2nd of 3 Sources of Atelectasis

Occurs from any space-occupying lesion of the thorax compressing the lung and forcing air out of the alveoli e.g. tumour.

A

Compression

26
Q

3rd of 3 Sources of Atelectasis

Causes of collapse include: pleural effusion, pneumothorax, hemothorax.

A

Collapse

27
Q

Atelectasis Neonatorum and Acquired Atelectasis

A

Two types of Atelectasis

28
Q

Primary Atelectasis

A

Atelectasis Neonatorum

29
Q

TYPE OF Atelectasis that Implies the lung has never been inflated, or has not inflated properly

A

Atelectasis Neonatorum

30
Q

TYPE OF Atelectasis that may be complete or partial

A

Atelectasis Neonatorum

31
Q

TYPE OF Atelectasis that most often seen in premature or other high risk births

A

Atelectasis Neonatorum

32
Q

TYPE OF Atelectasis that may be fatal

A

Atelectasis Neonatorum

33
Q

TYPE OF Atelectasis that implies the collapse of all or part of a lung that has previously been inflated

A

Acquired Atelectasis

34
Q

TYPE OF Atelectasis that commonly is caused by obstruction or compression

A

Acquired Atelectasis

35
Q
  • tachypnea
  • tachycardia
  • dyspnea
  • cyanosis
  • diminished chest expansion
A

Clinical Manifestations of Atelectasis

36
Q
  • reducing obstruction or compression
  • re-inflation of collapsed lung
  • deep breathing and positions that favour increased lung expansion, as appropriate
  • oxygen therapy
A

Treatment of Atelectasis

37
Q

is a common, chronic, inflammatory disorder of the airway that causes episodes of airway obstruction characterized by recurring symptoms, including respiratory hypersensitivity, that cause inflammation and acute attacks of intermittent obstruction.

A

Asthma

38
Q

Chronic inflammation increases airway hyperresponsiveness and results in decreased airflow in susceptible individuals, this inflammation causes recurrent episodes of wheezing, breathlessness, chest tightness and coughing. Contraction of the airway and subsequent swelling leads to further obstruction.

A

Chronic Inflammatory Conditions (Asthma)

39
Q

Episodes are common at night or in the early morning.

A

Chronic Inflammatory Conditions (Asthma)

40
Q

Widespread airflow obstruction is often reversible, either spontaneously or with treatment.

A

Chronic Inflammatory Conditions (Asthma)

41
Q

Roughly 7-8% of Canadians are affected (more biological females than males).

A

Chronic Inflammatory Conditions (Asthma)

42
Q

There are 2 main types (allergic and non-allergic), and the common factor in both is an exaggerated hyper-responsiveness to a variety of stimuli.

A

Chronic Inflammatory Conditions (Asthma)

43
Q
  • allergies
  • family history of asthma
  • exposure to tobacco smoke and environmental pollutions
  • hormones – biological females are more likely to develop adult-onset asthma after menopause
  • respiratory infections (especially viral)
  • premature birth and increased maternal age
  • maternal smoking and prenatal exposure to tobacco smoke
A

Risk Factors of Developing Asthma

44
Q
  • attack lasting for several hours and unresponsive to medical treatment
  • this is a medical emergency - call 911
  • patient will become fatigued and lethargic, due to respiratory muscle exertion
  • patient becomes cyanotic from lack of oxygen
  • may lead to respiratory failure and death
A

Status Asthmaticus 



45
Q

Severe asthma exacerbations that progress rapidly and do not respond to standard acute asthma protocol

A

Status Asthmaticus

46
Q

Cases in people over 35 years of age tend to be stress-related, or due to chronic exposure to inhaled pollutants or chemicals (often occupational, or prolonged exposure to smog).

A

Atopic Asthma (allergy induced asthma) 


47
Q

Allergies are the strongest predisposing factor for asthma.

A

Atopic Asthma (allergy induced asthma) 


48
Q

Chronic exposure to airway irritants or allergens increases the risk for developing asthma.

A

Atopic Asthma (allergy induced asthma) 


49
Q

Common Allergens:

seasonal: grass, tree and or weed pollens

perennial: mold, dust mites, animal dander especially cat and dog, cockroaches

A

Atopic Asthma (allergy induced asthma) 


50
Q

Treatment Considerations
Potential Modifications for treating px’s w/ Asthma

A
  1. awareness of cardiovascular health and hypertension
  2. caution re: allergens and sensitivities – careful with use of essential oils, detergents, disinfectants
  3. face cradle may feel claustrophobic, re: sensation of respiratory distress
  4. pillowing and/or prone position may inhibit diaphragm function
