Oxygen Therapy in Clinical Practice Quiz

Asthma is a chronic respiratory condition characterized by airway inflammation, and oxygen therapy may be used to relieve symptoms during exacerbations.

Oxygen therapy is commonly used as a supportive measure in Type II respiratory failure, where there is inadequate gas exchange.

The Venturi mask is a suitable oxygen delivery device for precise and controlled oxygen concentrations, useful in conditions requiring accurate FiO2.

Continuous positive airway pressure (CPAP) is commonly used in ARDS to maintain positive airway pressure, improve oxygenation, and reduce the need for intubation.

The recommended position for a patient receiving oxygen therapy via a nasal cannula is Semi-Fowler's, promoting optimal lung expansion and comfort.

The recommended flow rate for oxygen therapy in adults at rest is 1-2 liters per minute to maintain adequate oxygen saturation without the risk of oxygen toxicity.

The non-rebreather mask is an oxygen delivery device that provides the highest concentration of oxygen, preventing the rebreathing of exhaled air.

The primary goal of oxygen therapy in COPD is to relieve symptoms, improve exercise tolerance, and enhance the overall quality of life.

The nasal cannula is a common oxygen delivery system for long-term therapy at home, providing a continuous flow of oxygen through nasal prongs.

The high-flow nasal cannula is used in respiratory care to deliver high-flow rates of humidified oxygen, improving patient comfort and oxygenation.

The reservoir bag in a non-rebreather mask prevents the inhalation of ambient air, ensuring a higher concentration of oxygen and minimizing carbon dioxide rebreathing.

The target oxygen saturation level for patients receiving oxygen therapy is typically 90-95%, aiming to balance oxygen delivery with avoiding hyperoxia.

Prolonged high-flow oxygen therapy may lead to oxygen toxicity, causing lung damage and other adverse effects.

High-flow oxygen therapy in premature infants may increase the risk of bronchopulmonary dysplasia, a chronic lung disease affecting preterm infants.

Hyperbaric oxygen therapy is the preferred treatment for carbon monoxide poisoning, facilitating the elimination of carbon monoxide from the body.

Hypothermia may decrease the effectiveness of oxygen therapy by reducing metabolic oxygen demand and potentially compromising oxygen delivery to tissues.

The primary concern when administering oxygen therapy to a patient with hypercapnic respiratory failure is the risk of hyperoxia, which can suppress respiratory drive.
