What will be the nature of the breath after its involuntary hold?

Due to the involuntary holding of breath, hypoxia of the body begins. The cells lack oxygen. When breathing is restored, the lungs begin to actively work to saturate the red blood cells with oxygen. In most cases, these will be shallow breaths at a high rate. This speeds up the ventilation of the lungs. The first breath is usually deep, and then it is very difficult to take deep breaths. Also, the heart begins to beat strongly under the influence of adrenaline. The vessels expand, the pressure rises. After some time, all indicators return to normal.
