Final answer:
A Venturi mask and nasal cannula are pieces of medical equipment used to regulate the amount of oxygen delivered to a patient. They allow for precise adjustments based on the patient's oxygenation needs and ensure sufficient oxygenation when ventilation is inadequate.
Step-by-step explanation:
The equipment that enables a nurse to regulate the amount of oxygen delivered during oxygen administration to a client would be a Venturi mask and a nasal cannula. The Venturi mask is specifically designed to deliver a precise concentration of oxygen by mixing air with oxygen. It utilizes interchangeable nozzles or dials that allow the nurse to adjust the concentration of oxygen based on the patient's needs. The nasal cannula is a device that is generally used for more stable patients who require a lower concentration of oxygen and also allows for some regulation of oxygen flow. The regulation of oxygen delivery is essential to ensure adequate oxygenation of the blood and tissues, especially when the patient's ventilation is insufficient and the alveolar oxygen partial pressure drops. Proper oxygen delivery can help maintain the required difference in partial pressure that enables efficient diffusion of oxygen across the respiratory membrane. For patients who require assistance in maintaining open airways or specific respiratory rates and tidal volumes, additional equipment such as a Continuous Positive Airway Pressure device (CPAP) may be used. However, for the specific purpose of regulating oxygen delivery, the Venturi mask and nasal cannula are the appropriate choices.
