Q

chronic bronchitis

A

inflammation and swelling of the lining of the airways, leading to narrowing and obstruction generally resulting in a daily cough. the inflammation stimulates production of mucus, which can cause further blockage of the airways

A

a common lung disease that makes it hard to breathe. two main forms of COPD is chronic bronchitis and emphysema. shortness of breath, persistent airflow, limitation, and is primarily caused by smoking

Q

nursing management of asthma

A
  • control through the use of environmental control measures (reduce exposures to triggers)
  • teaching self management for condition
  • write action plan for treatment
  • pharmacotherapy individualized for the client (types of inhalers
  • continued assessment

Q

obstructive sleep apnea

A

characterized by partial or complete obstruction of the upper airway during sleep (2-3 mins). frequent periodic cessation of breathing during sleep. occurring during REM and NREM sleep. frequency ranges up to 400 periods per night. occurs when the structure of the pharynx or oral cavity block off the the air.

18
Q

nursing management of COPD

A

stop smoking, reduce frequency or severity of exacerbations, O2 therapy, medications, bronchodilators.

19
Q

hypoxemia

A

low level of oxygen in the blood

20
Q

hypercapnia

A

excessive amount of CO2 in the blood

21
Q

causes and risks of obstructive sleep apnea

A

-obseity, age, gender, smoking, enlarged tonsils, deviated septum, nasal polyps, reduced muscle tones

22
Q

assessment of obstructive sleep apnea

A
  • sleep/rest hx
  • physical appearance
  • weight
  • posture
  • energy level
  • sleep hygiene
  • polysomnography (sleep studies - HR, breathing)
23
Q

treatment with CPAP

A

continuous positive airway pressure.

  • mild, continuous flow of room air into nose, inflating airway
  • patients must initiate their own breaths
  • very effective
  • compliance poor
24
Q

asthma

A

narrowed bronchioles, chronic inflammatory disorder of airways

  • recurrent episodes of airway obstruction
  • reversible (spontaneously or with treatment)
25
Q

triggers of asthma

A
  • allergens
  • exercise
  • resp infections
  • drugs/food additives
  • gastroesophageal reflex disease
  • air pollutants
  • emotional stress
26
Q

mast cells

A

responsible for responding to information to an allergen “master cells”

27
Q

clinical manifestations of asthma

A

-wheezing, coughing, dyspnea, chest tightness, prolonged expiration, abrupt or gradual onset

28
Q

diagnosis of asthma

A
  • symptoms (frequency and duration)
  • variable airflow obstruction
  • spirometry the preferred test (non invasive- to determine vital capacity- determine what’s left over) how much you can breath in and out
  • allergy assessment
29
Q

general management approach for asthma

A
  • limit exposure to triggers
  • patient education
  • appropriate Pharmacotherapy
  • continuous assessment and monitoring of control and severity
  • regular follow up
30
Q

acute asthma episode

A
  • emergent situation
  • assess degree of severity
  • appropriate pharmacotherapy
  • supplemental oxygen PRN
31
Q

pharmacological interventions

A

-most patients require daily use of inhaled corticosteroids in addition to a short acting

32
Q

controllers for asthma

A

long acting, anti inflammatory and bronchodilators.

33
Q

relievers for asthma

A

quick relief, inhaled beta

34
Q

problems with the use of metered dose inhalers

A

activating it in the mouth while breathing through the nose, inspiring to rapidly, not holding the breath for 10 seconds

35
Q

COPD

A

a disease characterized by progressive, partially reversible airflow obstruction, systemic manifestations, and increasing frequency
-includes diseases that cause airflow obstruction

36
Q

COPD risk factors

A

smoking, expose to chemicals and pollutants, infection, aging

37
Q

pathophysiology of COPD

A

abnormal inflammatory response of lungs to noxious partials or gases

  • chronic inflammation causes narrowing in small peripheral airways
  • injury-repair process causes scar tissue formation and narrowing of airway
  • inflammation results in thickening of pulmonary vasculature
38
Q

chronic bronchitis

A

presence of cough and sputum production for at least 3 months in each of 2 consecutive years.

  • smoke or environmental pollutants irritate airways which leads to hyper secretion of mucus and inflammation
  • bronchial walls become thickened, bronchial lumen is narrowed, and mucus may plug airway, alveoli may become damaged
39
Q

emphysema

A

an abnormal distension of the air spaces beyond the terminal bronchioles, with destruction of the walls of the alveoli

40
Q

panlobular emphysema

A

destruction of the respiratory bronchioles, alveolar ducts and alveoli. all airspace is enlarged, but little inflammation.
-hyperextended (barrel chest), dyspnea on exertion, weight loss

41
Q

centrilobular emphysema

A

changes to the centre of the secondary lobule

leads to chronic hypoxemia, hypercapnia, polycythemia, right sided heart failure

42
Q

complications of emphysema

A

pulmonary heart disease, acute respiratory failure, acute exacerbations, depression/anxiety/panic

43
Q

management of COPD goals

A

prevent disease progression, reduce frequency and severity of exacerbations, alleviate breathlessness and other respiratory symptoms, improve exercise tolerance and daily activity, treat exacerbation and complication of the disease, improve health status and quality of life, reduce risk of mortality

44
Q

respiratory assessment

A
  • medical dx and hx
  • vital signs
  • pulse oximetry
  • inspection
  • palpation
  • auscultation
  • blood tests
  • spirometry
