Which part of the breathing cycle is assisted by the reservoir bag in a continuous flow oxygen system?

In a continuous flow oxygen system, the reservoir bag plays a crucial role during the inhalation phase of the breathing cycle. When the patient inhales, the bag allows for a larger volume of oxygen to be provided, which ensures a more effective delivery of oxygen directly to the lungs. The reservoir bag acts as a reserve that can quickly supply an increased flow of oxygen when the user takes a deep breath, thus enhancing the amount of oxygen they receive.

By having this reservoir, the system can accommodate the varying demands of the user’s breathing pattern, particularly during deep inhalation. This method of oxygen delivery is essential for maintaining adequate oxygen saturation in situations where continuous flow is necessary. Therefore, its primary function correlates specifically with the inhalation phase, as it supports the increased need for oxygen during that part of the respiratory cycle.
