CH.3 Cardiopulmonary Symptoms Flashcards
Symptoms
–subjective
–patient description
–Measured by patient perception
–example: paint, shortness of breath, cough
Signs
–objective
–measurable
–assessed values
–example: heart rate, blood pressure, respiratory rate
Assess symptoms to determine
–seriousness of problem
–potential underlying cause of problem
–effectiveness of treatment
Primary symptoms of cardiopulmonary disorders
–cough
–sputum production
–hemoptysis
–shortness of breath (dyspnea)
–chest pain
Cough
–one of the most common symptoms seen in patients with pulmonary disease
–Protective reflex
–Stimulation of receptors: pharynx, larynx, trachea, large bronchi, lung, and visceral pleura
–Cause by: inflammatory, mechanical, chemical, or thermal stimulation of cough receptor
–Key to determine etiology is careful history, physical examination and CXR
Possible cause of Cough: Inflammatory
–infection, lung abscess, drug reaction, allergy, edema, hyperemia, collagen, vascular disease
Possible causes of Cough: Mechanical
–Inhaled dusts, suction, catheter, food
Possible causes of Cough: Obstructive
–foreign bodies, aspirations of nasal secretions, tumor or granulomas within or around the lungs, aortic aneurysm
Possible cause of Cough: Airway wall tension
–pulmonary edema, atelectasis, fibrosis, chronic interstitial pneumonitis
Possible causes of Cough: Chemical
–inhaled irritant gases
–fumes
–smoke
Possible cause of Cough: Temperature
–inhales hot or cold air
Possible causes of Cough: Ear
–tactile pressure in the ear canal
Cough: Afferent pathway
–vagus, phrenic, glossopharyngeal, and trigeminal
Cough: Efferent Pathway
–smooth muscles of larynx and tracheobronchial tree via phrenic, spinal nerves
Cough: Phases
–Inspiratory
–Compression
–Expiratory
Reduced effectiveness of cough
–weakness of inspiratory or expiratory muscles
–inability of the glottis to open or close correctly
–obstruction, collapsibility, or alteration in shape or contours of the airway
–decrease in lung recoil (emphysema)
–abnormal quantity or quality of mucus production (thick sputum)
Acute disease
–sudden onset
–severe, short course
–self-limiting: viral infection
Chronic disease
–persistent
–last more than 3 weeks
-Causes
–Postnasal drip: most common
–Asthma
–COPD exacerbation
–Allergic Rhinitis
–GERD
–Chronic bronchitis
–Bronchiectasis
–Left Heart Failure: CHF, pulmonary edema
