The Hering–Breuer Inflation Reflex – Influence on Respiration (Nursing)

00:01 The last influence is the inflation reflex also known as the Herring-Breuer reflex.

00:09 This is when stretch receptors in the pleurae of the thoracic cavity and airways are stimulated by lung inflation.

00:18 If the lungs begin to overinflate, they send inhibitory signals to the respiratory centers in order to end inhalation and allow for expiration.

00:31 So we're going to inhibit that dorsal respiratory group and we're going to activate the ventral respiratory group.

00:39 This may act as a protective response so that we don't hyper or over inflate our thoracic cavity for example during exercise when we're breathing we have a tendency to breathe really hard and we need to be able to control just how inflated our lungs get.
