Hypoventilation syndrome. Congenital central hypoventilation syndrome (CCHS) is a rare disorder of respiratory control with autonomic nervous system dysregulation (ANSD).
Frost forms in much the same way as dew forms. Frost usually forms when a surface cools through loss of infrared radiation to a temperature which is colder than the dewpoint of the air next to the surface, AND the temperature of that surface is below freezing (32 deg F, or 0 deg.C).The source of this moisture is water vapor contained in the air.rost forms in much the same way as dew forms.

1 It is described as a light frost if the temperature is between 32 and 29 degrees Fahrenheit. 2  A moderate frost is the term used if the temperature is between 28 and 25 degrees Fahrenheit. 3  If the temperature goes below 25 degrees Fahrenheit, it is a killing frost and many of the plants will turn black.his is because air temperature affects many of the plantâs basic physiologic processes, such as the absorption of nutrients. 1  It is described as a light frost if the temperature is between 32 and 29 degrees Fahrenheit. 2  A moderate frost is the term used if the temperature is between 28 and 25 degrees Fahrenheit.
