Module 6: Respiratory System Flashcards
Upper Respiratory Tract
- Nasal cavity
- Nasopharynx
- Palatine tonsils
- Oropharynx
- Larynx
- Trachea
- Epiglottis
Lower Respiratory Tract
- Right & Left primary Bronchi
- Secondary Bronchi
- Bronchioles
- Terminal Bronchioles
- Respiratory Bronchioles
- Alveolar ducts
- Alveoli
Diagnostic Tests used to Evaluate Respiratory Health Problems
- Spirometry-pulmonary function testing (PFT)
- Oximetry
- Exercise tolerance testing
- ABG’s
- Radiography - Chest Xray
- Bronchoscopy (tube looking in airway)
- Sputum C&S
What is Spirometry (PFT)?
- Used to test pulmonary volumes by measuring volume and airflow times
- Measures how much air is exhaled,
- Measures breaths in and out in 1 min
- Measures how much air is left after a normal exhale
What is Oximetry?
Measures oxygen saturation
What is exercise tolerance testing?
- Looks at how exercise affects lungs
- Useful for diagnosis of chronic pulmonary disease
What are ABG’s?
- Arterial blood gasses
- Blood sample from the arterial blood
- Allows us to measure blood from lungs before gas exchange occurs
- Can tell us PO2, PCO2, Serum pH, Electrolytes & Blood Glucose
What is Radiography?
Chest X-Ray
used to help identify tumors or infections
What is a Bronchoscopy?
- Procedure that allows a doctor to examine the inside of the lungs using a small camera
- May be used in performing a biopsy, checking for lesions or bleeding
What is Sputum C&S?
- Test on exudates from the upper respiratory tract
- Identifies pathogens and assists in determining therapy
S&S of Alterations in Respiratory Health
- Sneezing
- Coughing
- Sputum production
- Breathing pattern changes
- Abnormal breath sounds
- Dyspnea
- Cyanosis
- Pleural pain
- Clubbed fingers
- Changes in ABG’s
Examples of Abnormal Breath Sounds
- Rales (light bubbly or cracking sounds)
- Rhonchi (deep, harsh sounds resulting from mucus)
Definition and cause of the common cold
- Viral Infection affecting the upper respiratory system
- Spread through respiratory droplets
S&S of the Common Cold
- Nasal congestion
- Sneezing
- Increased secretions
- Mouth breathing
- Watery eyes
- Sore throat
- Headache
- Slight fever
- Malaise
- Cough
Treatment of the Common Cold
- Based on symptoms
- Acetaminophen
- Decongestants
- Humidifiers
Cause of Sinusitis
A bacterial infection that lines the sinuses, secondary to a cold or allergy due to mucus build up
S&S of Sinusitis
- Pain in facial bones
- Nasal congestion
- Fever
- Sore throat
Treatment of Sinusitis
- Decongestants
- Antihistamines
- Analgesics
- Antibiotics are often required to eradicate the infection
- Nasal saline
Cause of Influenza
- A viral infection known a the “flu” that attacks/affects the upper and lower respiratory tracts
- Transmitted via air droplets (cough, sneeze)
- New strands appear all the time
- 3 groups A,B,C (A is most common)
S&S of Influenza
- Sudden acute onset
- Fever
- Fatigue
- Aching body pains
Treatment of Influenza
- Treatment is symptomatic & supportive unless bacterial infection occurs
- Antiviral drugs
Cause of Pneumonia
- Lower respiratory tract infection
- May develop as a primary infection or secondary to another infection
- Bacteria entering the lungs
- Aspiration or inflammation of lungs
- Occasionally can be blood borne
S&S of Pneumonia
- Sudden onset
- High fever with chills
- Fatigue
- Leukocytosis
- Dyspnea
- Pleural pain
- Productive cough
- Confusion
- Rales
Treatment of Pneumonia
- Antibacterial medication
- Fluids
- Drugs to reduce fever - Acetaminophen
- Oxygen
Cause of SARS
“Severe Acute Respiratory Syndrome”
Acute respiratory infection caused by a microbe that is transmitted via respiratory droplets (coughing, sneezing)
S&S of SARS
- Fever
- Body aches
- Dyspnea
- Anorexia
- Diarrhea
- Dry cough
- Chills
- Headache
- Muscle stiffness
Treatment of SARS
-Antiviral medications and glucocorticoid (methylprednisolone)
