lungs

Respiratory process

The diaphragm descends into the abdominal cavity during inspiration, causing negative pressure in the lungs

The negative pressure draws air from the area of greater pressure, the atmosphere, into the area of lesser pressure, the lungs

In the lungs, air passes through the terminal bronchioles into the alveoli to oxygenate the body tissues

Respiratory process

At the end of inspiration, the diaphragm and interscostal muscles relax and the lungs recoil

As the lungs recoil, pressure within the lungs becomes higher than atmospheric pressure, causing the air, which now contains cellular waste products carbon dioxide and water to move from the alveoli in the lungs to the atmosphere

Bronchial Asthma

Intermittent & reversible airflow obstruction affecting the lower airway.

Obstruction is due to:

Constriction of bronchial smooth muscle due to stimulation of the nerve fibers

Etiology:

allergens, cold air, dry air, airborne particles, microorganism, aspirin à inflammation

exercise, upper respiratory illness (viruses), unknown reasons à bronchospasm

Bronchial Asthma

Bronchial Asthma

Physical assessment findings:

Wheezing is louder during exhalation

Dyspnea, cough, use of accessory muscle of respiration, barrel chest (chronic severe asthma)

Cyanosis, poor O2 saturation (pulse oximetry)

Change of LOC & tachycardia due to hypoxemia

PuLmOnArY fUnCtiOn teSts – most accurate test for asthma

Forced Vital Capacity (FVC) – volume of air exhaled from full inhalation to full exhalation

Forced Expiratory Volume (FEV1) – volume of air blown out as hard and fast as possible during the first second of the most forceful exhalation after

Page 4: Respiratory System

the greatest full inhalation

Peak Expiratory Rate Flow (PERF) – fastest airflow rate reached at any time during exhalation

Methacholine is inhaled (induces bronchospasm) & then FVC, FEV1 & PERF is measured then brochodilators will be given à an # 12% of values: asthma

inhaler – Budesonide, Fluticasone, Beclomethasone, Triamcinolone, Flunisolide

Mast cell stabilizer

Cromolyn sodium (Intal); helps prevent atopic asthma attacks (prevent mast cell membranes from opening when an allergen binds to IgE) but are not useful during an acute episode

Monoclonal antibodies

Omalizumab (Xolair), approved in 2003 only – binds to IgE receptor sites on mast cells & basophils preventing the release of chemical mediators for inflammation

Bronchial Asthma

Exercise/ Activity

Aerobic exercise (recommended)

assist in maintaining cardiac health, enhancing skeletal muscle strength, and promoting ventilation and perfusion

Swimming

Oxygen Therapy

symptom) à yellow, purulent, copious, blood streaked sputum

Bronchospasm, Acute respiratory infections, cyanosis, DOE, RSHF (cor pulmonale)

Most important risk factor for COPD is SMOKING!!!

Effects of Tobacco Smoke:

Page 8: Respiratory System

Tobacco smoke triggers the

release of EXCESSIVE amounts

of elastase protease that

breaks down elastin which is a major component of alveoli

Impairs & inhibits the action of cilia

CXR to rule out other chest diseases & to check the progress of clients with

respiratory infections or chronic disease

COPD

Interventions:

Mainstays of COPD management:

Airway maintenance

Monitoring

Drug Therapy

O2 therapy

COPD

Airway maintenance:

Keep the client’s head, neck and chest in alignment

Assist the client to liquefy secretions and clear the airway of secretions

Breathing Techniques

COPD

Airway maintenance:

Controlled coughing

advise client to cough on arising on the morning, before mealtimes, before bedtimes

to cough effectively, the client sits in a chair or on the side of a bed with feet placed firmly on the floor. Instruct the client to turn the shoulders inward and to bend the head slightly downward hugging a pillow against the stomach. The client then takes a few deep breaths.

Page 9: Respiratory System

After the 3rd to 5th deep breath ( pursed-lip breathing), instruct the client to bend forward slowly while coughing two or three times from the same breath

Chest physiotherapy & postural drainage

Postural Drainage

COPD

Monitoring:

Assess COPD client at least q2°

O2 Therapy:

The need for O2 therapy & its effectiveness can be determined by ABG values & O2 saturation by pulse oximetry

usually, 2-4 L/min or even 1-2 L/min via nasal cannula or up to 40% via venturi mask

Low-flow O2 because low arterial oxygen level is the COPD client’s primary drive for breathing

COPD

Drug Therapy:

involves the same inhaled and systemic drugs for asthma

PNEUMONIA

one of the most common complications of COPD:

* Teach clients to avoid large crowds and stress the importance of receiving a pneumonia vaccination and a yearly influenza vaccine “flu shot”

It results from inflammation and destruction of the structural components of the bronchial wall brought about by:

chronic pulmonary infection (P. aeruginosa, H. influenzae)

tumor or foreign body

Flail Chest

Complication of chest trauma occurring when 2 or more adjacent ribs are fractured at two or more sites, resulting in free-floating rib segments

Fractured Ribs/ Sternum

Paradoxic movement of the chest:
