Q

Symptoms occur weekly, however not every day. Those episodes now start to affect their ability to go to school, work, and exercise. It is not unusual for these patients to wake up in middle of the night with coughing, wheezing and chest tightness. Night symptoms occur more than 2 times per month. These patients will be on low dose inhaled corticosteroids via an MDI (metered dose inhaler).

Q

Symptoms occur daily, requiring bronchodilator inhaler use. These episodes affect activity and sleep. They will begin to have symptoms at night more than 1 time per week. These patients will be treated with:

  1. low dose inhaled corticosteroids
  2. LABAs (Long Acting Beta Agonist drugs). Ex: salmeterol/Serevent. These drugs open up airways and relax bronchiole airways. They are LONG ACTING- work for about 12 hrs! LABAs are used for prophylaxis, for the control of asthma (whereas SABAs (short acting) are used for acute flare-ups).

Q

This is the worst case scenario! Symptoms will be continuous and ongoing; they are there all the time. These patients will have frequent episodes during the day and at night. Additionally, activities are limited because of their symptoms. They will be treated with multiple medications at a time:

  1. High dose inhaled corticosteroids
  2. LABAs
  3. PO corticosteroids- Prednisone. Key thing to remember in terms of patient teaching for anyone taking a corticosteroid by mouth is that it causes GI distress so take with food or milk.

Q

is a condition in which the walls between the alveoli/air sacs within the lung lose their ability to stretch and recoil (in English: these patients lose the elasticity of their lungs). The patient will have alveoli destruction as the air sacs weaken overtime. When elasticity of the lung tissue is lost, air can get trapped (barrel chest) in the air sacs impairing the exchange of O2 and CO2.

46
Q

Mucosal edema- swelling of the bronchiole tubes which reduces airway diameter
o Bronchospasm of the smooth muscles of the respiratory tract causing further narrowing of the airways
o Mucous production- these patients make LOTS of mucous, however they have difficulty bringing it up.
during an acute episode of asthma, they start hyperventilating, they become air hungry and start using accessory muscles to breathe. These patients truly experience insensible fluid loss

A

Asthma

47
Q

Classic Symptoms:
o Coughing- with or without mucous production
o Chest tightness
o Wheezing- an expiratory wheeze, however you may also hear it on inspiration. Depending on how loud the wheeze is, you may be able to hear it without a stethoscope.
o Dyspnea
is a chronic condition, overtime you will see that they do pursed lip breathing- it takes them a much longer time to breathe out because they have air trapping

A

Clinical Manifestations of Asthma

48
Q

• Anxious
o Diaphoretic
o Tachycardic
o Hypoxemic
• overtime, their expiration becomes longer than inspiration
• often occur at night or in early AM and they may begin abruptly.

A

Asthma exacerbations

49
Q

Sputum Analysis and blood tests- Eosinophil Count. Many times it will be elevated, especially if the patient also has allergies.
ABG- In an acute flairup, the patient will be hyperventilating (getting rid of CO2-acid), therefore their pH will go up, placing them in a state of Respiratory Alkalosis.
Pulse Oximetry
PFT (Pulmonary Function Test)- assesses Tidal Volume (how much air they’re taking in and how much air they’re breathing out)
CXR- may pick up hyperinflation of the lungs, aka “air trapping”

A

A

Chronic Bronchitis

52
Q

o chronic inflammation and swelling of the peripheral airways (bronchi)
o excessive mucus production and accumulation
o bronchial airway obstruction (result of inflammation and hypersecretion of mucous)
o hyperinflated alveoli in the lungs

A

Chronic Bronchitis

53
Q
  1. Inflammation of the bronchial tree
  2. Hypersecretion of mucous from goblet cells in respiratory tract
  3. Loss of ciliary hairs in the respiratory tract (function is to keep out foreign material) so as they’re making all this mucous they can’t get it up so it goes deeper into the lungs and settles there, thus making them prone to many respiratory tract infections
  4. Continuous bronchospasm
  5. Hyperinflated lung
  6. Airway obstruction
A

Chronic Bronchitis

54
Q

periorbital edema
o JVD
o sacral edema
o dependent edema (hands and feet)

A

Right sided heart failure related to chronic bronchitis

55
Q

is a condition in which the walls between the alveoli/air sacs within the lung lose their ability to stretch and recoil (in English: these patients lose the elasticity of their lungs). The patient will have alveoli destruction as the air sacs weaken overtime. When elasticity of the lung tissue is lost, air can get trapped (barrel chest) in the air sacs impairing the exchange of O2 and CO2
• On a CXR, you will see dead space in the lungs (as a result of dead alveoli).

A

Emphysema

56
Q

o Extreme SOB
o Cough with or without sputum production
o Limited exercise tolerance
o Weight loss (dyspnea interferes with eating)- patients are very skinny with a barrel chest
o Generalized fatigue
o Anxiety
o Use of accessory muscles to breathe
o Pursed lip breathing
o Hypoxia and hypercapnea overtime
• pursed lip breathing, expiration will take longer than inspiration
• Overinflated lung on a CXR and flattening of the diaphragm

A

Clinical Manifestations of Emphysema

57
Q

air builds up in the pleural cavity and compresses the lung. As the air pressure continues to compress the lung, that lung will collapse (atelectasis). Therefore, a tube is placed in the 2nd intercostal space in order to remove the excess air.

A

Pneumothorax

58
Q

blood or fluid builds up in the pleural cavity. Because the blood/fluid is heavy, it settles at the bottom of the lung. Therefore, a tube is inserted somewhere between the 4th and 5th intercostal spaces in order to drain the excess fluid settling at the bottom of the lung.

A

hemothorax

59
Q

regulates the amount of negative pressure applied to the chest- suction promotes drainage of fluid and removal of air. The physician determines how much suction should be applied to the patient (how much water). The chamber is filled with 10-20 cm of sterile water and you will see there is continuous bubbling as air and fluid is being pulled out of the chest.

A

Suction Control chamber

60
Q

prevents air from moving back into the chest on inspiration. This chamber has the smallest amount of water in it. When the patient breathes in and out you will see a gentle rise and fall of the water

A

Water Seal chamber

61
Q

air and fluid become trapped in the lung and tension will develop in the chest as pressure starts to build in the lung.

A

tension pneumothorax

62
Q
  • SOB
  • Anxiousness
  • Wheezing stops with SOB
  • Symptoms increase
  • Cyanosis
  • asthma that does not respond
  • Can occur w/little or no warning
  • Severe bronchospasm
  • Mucus plugging leading to asphyxia
  • Hypoxemia
  • Respiratory alkalosis
A

Status Asthmatics

63
Q

o Cardiovascular compromise- they now develop a decrease in venous blood return because too much pressure is being applied to their lungs. The nurse may need to decrease the pressure setting on the machine. In order to assess for cardiovascular compromise, check the patient’s central venous pressure and pulmonary capillary wedge pressure.
o Pneumothorax- the reason could be that too much pressure is being applied to the lungs. Chest tubes will need to be inserted and the machine settings lowered.
o Pulmonary infection- these patients have an impaired cough reflex to begin with and have decreased mobility (bedrest).

A

Patient problems with Vents

64
Q

o Bronchopneumonia- involves distal airways / alveoli (deep in respiratory tract)
o Lobular pneumonia- involves a part of the lobe of the lung
o Lobar pneumonia- involves an entire lobe

A

Types of Pneumonia

65
Q

Occurs suddenly, without warning, when air enters the pleural space through a breach of either the parietal or visceral pleura. These patients will end up with extreme hypoxia and their lung will collapse.
Etiology:
o Rupture of an air-filled bleb or blister on the surface of a lung, allowing air from the airways to enter the pleural cavity.
o Diffuse interstitial lung disease
o Severe emphysema

A

Spontaneous Pneumothorax

66
Q

Occurs when air is drawn into the pleural space from a lacerated lung or through a small opening or wound in the chest wall. With a tension pneumothorax, there is increasing positive pressure in the pleural space with each breath (air gets trapped and can not escape on expiration through the air passages or chest wall as in an open pneumothorax). On inspiration, the mediastinum will shift toward the unaffected lung impairing ventilation. On expiration, the mediastinal shift will compress the heart and its blood vessels (vena cava) leading to a reduction in venous return.

A

Tension Pneumothorax

67
Q 
o Profuse diaphoresis
o Agitation
o Respiratory distress- air hunger
o Cyanosis
o Tachycardia- heart compensates
o Tachypnea- really struggling to breathe
o May go into cardiac arrest
