P1.3: RESPIRATORY: BRONCHIAL ASTHMA Flashcards
A condition characterized by increased responsiveness of the tracheobronchial tree to various stimuli with resulting bronchospasm and inflammation of the bronchial mucosa
BRONCHIAL ASTHMA
AIRFLOW LIMITATIONS
Risk Factors of Bronchial Asthma
- Cigarette smoking
- Respiratory infection
- Extreme emotions
- Seasonal changes
- Allergic reactions
- Family history
- Occupational exposure to dust or chemical irritant
What are the 3 causes of airflow limitations in bronchial asthma
- Bronchospasm
- Increased Mucous Secretions
- Mucosal Edema
What does HAPE stands for?
High Altitude Pulmonary Edema
2 types of Bronchial Asthma
- Intrinsic Asthma
- Extrinsic Asthma
Type of Bronchial Asthma:
- Occurs as a response to an allergen or trigger to which the patient is hyperresponsive
- Mediated by IgE and appears more often in children and may disappear during adolescence
Extrinsic Asthma
Type of Bronchial Asthma:
- Considered a non-allergic type of asthma
- Triggered by intrinsic factors which includes emotional stress, changes in humidity and temperature, exposure to noxious fumes and coughing
Intrinsic Asthma

- Endocrine factors (menses, pregnancy, thyroid disease)
Manifestations of Asthma Attacks:
- Respiratory distress
- Dyspnea/ “air hunger”
- Tachypnea
- Prolonged expiratory phase
- Tachycardia
Physical Signs of Asthma Attacks:
▪ Retraction of intercostals and sterna muscles
▪ Percussion- hyperresonant
▪ Distant breath sounds
▪ Ronchi, wheezes, rales
Diagnosis of Asthma:
- History and physical examination
- Arterial Blood Gas (ABG) analysis
- Serum IgE levels
- Complete Blood Count (CBC) with Differential Count
- Chest X-rays
- Pulmonary Function Studies
- Skin Testing
- Bronchial Challenge Testing
- Pulse Oximetry
Diagnosis of Asthma:
It reveals hypoxemia
Arterial Blood Gas (ABG) analysis
Diagnosis of Asthma:
increase from allergic reaction
Serum IgE levels
Diagnosis of Asthma:
it shows increase eosinohil count
Complete Blood Count (CBC) with Differential Count
Diagnosis of Asthma:
May show hyperinflation with areas of local atelectasis
Chest X-rays
Diagnosis of Asthma:
It may show decreased peak flows and forced expiratory volume in 1 second, low-normal or decreased vital capacity, and increased total lung and residual capacities
Pulmonary Function Studies
Diagnosis of Asthma:
It may identify specific allergens
Skin Testing
Diagnosis of Asthma:
It shows the clinical significance of allergens identified by skin testing
Bronchial Challenge Testing
Diagnosis of Asthma:
It may show decreased oxygen saturation
Pulse Oximetry
These methods are aimed at preventing attacks and intervening early during an attack:
Non-pharmacologic methods
2 types of Pharmacologic Management:
- Quick-relief
- Long Term control medications
Pharmacologic Management:
- Bronchodilators which act primarily to relax bronchial smooth muscle and dilate the airways
- Anticholinergics such as ipratropium are used to increase the effects of bronchodilators
Quick-relief
Pharmacologic Management:
- Corticosteroids, leukotriene modifiers
- Sympathomimetic aerosol sprays
Long Term Control Medications
Examples of Long-Acting Control Medications
- Corticosteroids
- Mast Cell Stabilizer
- Long-Acting beta-Adrenergic Agents
- Xanthine Derivatives
- Leukotriene Modifiers (inhibitors)
- Combination Products
Examples of Quick-Relief Medications
- Short-Acting Beta-Adrenergic Agents
- Anticholinergics
Nursing Management Requires extensive education of the patient and family regarding:
- pursed –lip and diaphragmatic breathing
- use of peak flow meter
- effective coughing techniques
- maintaining adequate hydration
- when to notify the physician
WHAT ARE THE INFLAMMATORY DISORDERS
- Sinusitis
- Laryngitis
- Pharygitis
INFLAMMATORY DISORDER:
- A condition characterized by the inflammation of the mucus membrane lining the sinuses
- May either be a bacterial infection or secondary to a viral exposure
SINUSITIS
1. ACUTE SINUSITIS
2. CHRONIC SINUSITIS
TYPE OF SINUSITIS:
- Most common causes are allergy and bacterial infection
- Damage to the mucusa of the sinuses are reversible
Acute Sinusitis
TYPE OF SINUSITIS:
- May result from untreated acute sinusitis
- Damage to the mucosa of the sinuses are irreversible
Chronic Sinusitis
MANIFESTATIONS OF SINUSITIS
- Facial pain and headache
- Toothaches
- Headache for frontal and ethmoid sinuses
- Mucoid nasal discharge
- Nasal congestion
- Orbital edema
- Cough and sore throat
- Inability to smell
- Lack of appetite
- Fever
DIAGNOSIS OF SINUSITIS
- History and Physical Examination
- Sinus X-Rays
- Computed Tomography Scanning
DIAGNOSIS OF SINUSITIS:
- For instance, to know if there was trauma
History and Physical Examination
DIAGNOSIS OF SINUSITIS:
Detect sinus opacity, mucosal thickening, bone destruction, and air-fluid levels
Sinus X-ray
DIAGNOSIS OF SINUSITIS:
Most effective diagnostic tool. It is also used to rule out other local or systemic isorders, such as tumor, fistula, and allergy
Computed Tomography Scanning
If the sinusitis does not respond to antibiotics, surgical intervention may be required:
- Functional Endoscopic Sinus Surgery (FESS)
- Anthral Irrigation
- Caldwell-Luc Surgery
Surgical intervention If the sinusitis dont respond to antibiotics:
Use of fiberoptic endoscope is used to disect nasal tissue
Complications:
* Nasal bleeding
* Orbital hematoma
* Injury to the optic nerve which may lead to blindness
Functional Endoscopic Sinus Surgery (FESS)
Surgical intervention If the sinusitis dont respond to antibiotics:
A sharp metal instrument (known as trocar) is inserted through anthrum into the lateral wall of the nose into the sinus
Anthral Irrigation
Surgical intervention If the sinusitis dont respond to antibiotics:
An incision is made under the upper lip, above the lateral incisor teeth and part of the bony anthrum is removed, producing a permanent window allowing drainage and removal of the deceased mucosa and periosteum
Usually done when antibiotic treatment is no longer effective
Caldwell-Luc Surgery
- Also known as radical anthrum surgery
- Indicated for chronic maxillary sinusitis
INFLAMMATORY DISORDER:
Commonly known as sore throat — is an inflammation of the pharynx, resulting in a sore throat. Thus, it is a symptom, rather than a condition.
PHARYNGITIS
RISK FACTORS OF PHARYNGITIS
- Viral and/or bacterial infections
- Allergies
- Dry indoor air
- Muscle strain
- Gastroesophageal reflux disease (GERD)
MANIFESTATIONS OF PHARYNGITIS
- Sore throat
- Dry, scratchy throat
- Pain when swallowing
- Pain when speaking
Diagnosis of Pharyngitis requires a ________ exam and ________ to assess for all the possible causes of pharyngitis.
physical; laryngoscopy (scope exam in a clinic)
INFLAMMATORY DISORDER:
Inflammation of the vocal cords can alter the way the vocal cords come together and vibrate, causing voice changes.
LARYNGITIS
ACUTE AND CHRONIC LARYNGITIS
- Can be acute (short-term), lasting less than three weeks.
- Or it can be chronic (longterm), lasting more than three weeks
DIAGNOSIS OF LARYNGITIS
- History and physical examination
- Formal voice analysis and fiberoptic laryngoscopy
- Stroboscopy
TREATMENT/MANAGEMENT OF LARYNGITIS
- Voice rest
- Steam Inhalation
- Avoidance of irritants
- Dietary modification
MEDICATIONS FOR LARYNGITIS
-
Oral antifungal agents such as
fluconazole - Mucolytics like guaifenesin
- Anti-reflux medications
