Oxygen Therapy and Delivery Devices

This video tutorial by Christina, a nurse practitioner, covers various types of oxygen therapy for patients with impaired gas exchange. It explains the differences between low and high flow oxygen delivery systems, including devices like nasal cannula, simple mask, partial rebreather, non-rebreather, Venturi mask, and CPAP/BIPAP. The tutorial also highlights key nursing considerations, such as monitoring oxygen levels and preventing oxygen toxicity.

What is the primary purpose of oxygen therapy?

• To improve gas exchange in patients with respiratory or cardiac issues

• To increase carbon dioxide levels in the blood

• To decrease blood pressure

• To enhance digestion

Which device is typically used for low-level oxygen delivery?

• Venturi mask

• BiPAP

• CPAP

• Nasal cannula

What is the maximum recommended flow rate for a nasal cannula with a humidifier?

• 8 liters per minute

• 6 liters per minute

• 4 liters per minute

• 2 liters per minute

What should a nurse assess for in a patient using a simple mask?

• Signs of respiratory distress

• Signs of hypertension

• Signs of dehydration

• Signs of hypothermia

What is the primary function of a non-rebreather mask?

• To humidify the air

• To measure exhaled carbon dioxide

• To allow rebreathing of exhaled air

• To prevent room air from diluting oxygen concentration

Which device is used for high flow oxygen delivery and provides an exact FiO2?

• Nasal cannula

• Partial rebreather

• Venturi mask

• Simple mask

What is a potential risk of prolonged oxygen therapy?

• Hypothermia

• Oxygen toxicity

• Dehydration

• Increased blood pressure

What should be monitored to prevent infection when using a humidifier?

• Temperature

• Humidity levels

• Fungus and bacteria growth

• Oxygen concentration

Which condition is a common indication for using CPAP?

• Pneumonia

• Bronchitis

• Obstructive sleep apnea

• Asthma

What is the role of positive pressure in non-invasive ventilation?

• To decrease oxygen levels

• To open alveoli and prevent intubation

• To reduce blood flow

• To increase carbon dioxide levels
