What are the potential side effects of decongestants in relieving nasal congestion?
Decongestants can have side effects like increased heart rate and blood pressure.
What is the difference between hypoxia and hypoxemia?
Hypoxia is a deficiency of oxygen reaching the body's tissues, while hypoxemia is reduced oxygen in the blood, both caused by various conditions like respiratory depression and cardiac failure.
What is the purpose of oxygen therapy?
Oxygen therapy is used to correct tissue hypoxia due to conditions like respiratory failure, anemia, cardiovascular deficiencies, and high altitude sickness.
What is the function of mucolytics in respiratory conditions?
Mucolytics alter the structure of mucus, enhancing its flow out of the respiratory tract, and are used for conditions like cystic fibrosis.
What is the Fraction of inspired oxygen (FiO2) and what does it measure?
Fraction of inspired oxygen (FiO2) measures the percentage of oxygen in the air, ranging from 21% in room air to 100% in pure oxygen, with varying levels delivered through nasal cannulas or masks.
Explain the difference between hypoxia and hypoxemia, and provide examples of conditions that can cause each.
Hypoxia is a deficiency of oxygen reaching the body's tissues, while hypoxemia is reduced oxygen in the blood. Hypoxia can be caused by conditions like respiratory depression and cardiac failure, while hypoxemia can be caused by anemia and respiratory failure.
Describe the functions of expectorants and mucolytics in treating respiratory conditions, and provide examples of when each type of medication is used.
Expectorants stimulate mucus secretion in dry, irritated areas of the respiratory tract, promoting the removal of sputum. Mucolytics alter the structure of mucus, enhancing its flow out of the respiratory tract. Expectorants are used for conditions with dry coughs, while mucolytics are used for conditions like cystic fibrosis.
Explain the potential side effects and mechanisms of action of decongestants and anti-histamines in treating respiratory conditions.
Decongestants work by reducing swelling in the airway lining, easing nasal congestion, but they can have side effects like increased heart rate and blood pressure. Anti-histamines block the effects of histamine released during allergic reactions, helping to relieve symptoms like airway swelling and sneezing, but they can cause sedation.
Discuss the purpose of oxygen therapy and the measurement of fraction of inspired oxygen (FiO2) in the context of correcting tissue hypoxia.
Oxygen therapy is used to correct tissue hypoxia due to conditions like respiratory failure, anemia, cardiovascular deficiencies, and high altitude sickness. Fraction of inspired oxygen (FiO2) measures the percentage of oxygen in the air, ranging from 21% in room air to 100% in pure oxygen, with varying levels delivered through nasal cannulas or masks.
Explain the potential risk of oxygen toxicity and the importance of safe handling of oxygen cylinders in medical settings.
Oxygen toxicity can occur if over 60% oxygen is delivered for extended periods, potentially leading to irritation or collapse of alveoli. It's essential to handle oxygen cylinders safely, storing them away from heat sources and naked flames.
What are the different types of over-the-counter medications for respiratory conditions?
Cough suppressants, expectorants, mucolytics, anti-muscarinic, antihistamines, anti-pyretic, sympathomimetic, and decongestants.
How do cough suppressants work?
Cough suppressants aim to reduce the frequency and severity of coughing by interrupting the coughing reflex in the brain.
What is the purpose of expectorants?
Expectorants stimulate mucus secretion in dry, irritated areas of the respiratory tract, promoting the removal of sputum.
What is the difference between hypoxia and hypoxemia?
Hypoxia is a deficiency of oxygen reaching the body's tissues, while hypoxemia is reduced oxygen in the blood.
What is oxygen toxicity and how can it occur?
Oxygen toxicity can occur if over 60% oxygen is delivered for extended periods, potentially leading to irritation or collapse of alveoli. It's essential to handle oxygen cylinders safely, storing them away from heat sources and naked flames.
Study Notes
Respiratory Medications and Oxygen Therapy Overview
- Allergic rhinitis, or hayfever, is caused by the body's immune system mistaking allergens like pollen and dust as harmful invaders, triggering an allergic response with symptoms like sneezing and itchy eyes.
- Over-the-counter medications for respiratory conditions include cough suppressants, expectorants, mucolytics, anti-muscarinic, antihistamines, anti-pyretic, sympathomimetic, and decongestants.
- Cough suppressants aim to reduce the frequency and severity of coughing, typically used for dry coughs, and work by interrupting the coughing reflex in the brain.
- Expectorants stimulate mucus secretion in dry, irritated areas of the respiratory tract, promoting the removal of sputum.
- Mucolytics alter the structure of mucus, enhancing its flow out of the respiratory tract, and are used for conditions like cystic fibrosis.
- Decongestants work by reducing swelling in the airway lining, easing nasal congestion, but they can have side effects like increased heart rate and blood pressure.
- Anti-histamines block the effects of histamine released during allergic reactions, helping to relieve symptoms like airway swelling and sneezing, but they can cause sedation.

- Hypoxia is a deficiency of oxygen reaching the body's tissues, while hypoxemia is reduced oxygen in the blood, both caused by various conditions like respiratory depression and cardiac failure.
- Oxygen delivery methods include nasal cannulas, simple face masks, pocket masks with oxygen nipple, and bag-valve-masks with reservoir, each delivering different percentages of oxygen.
- Oxygen toxicity can occur if over 60% oxygen is delivered for extended periods, potentially leading to irritation or collapse of alveoli. It's essential to handle oxygen cylinders safely, storing them away from heat sources and naked flames.
