Infant apnea is one of the most frequent causes involved in Sudden Infant Death Syndrome (SIDS), so it is very important to have equipment and systems that allow not only to detect the infant apnea, but to take an immediate action before an apnea episode. The apnea and vital signs monitor for infants is oriented to the permanent monitoring of an infant, with the purpose of detecting an eventual apnea episode. And if the above is detected, the system is capable of sending an alert to parents or caregivers, in addition to taking the first action recommended by specialists before an apnea episode, which is to move the baby, with the purpose of making the baby breathe again. In addition to monitoring the babys vital signs, the apnea and vital signs monitor for infants is capable of making measurements of different variables in the environment such as humidity and temperature in order to establish the possible relationship between environmental factors and apnea episodes. This invention w ill allow a better understanding of the causes that can derive in the unfortunate SIDS (Sudden Infant Death Syndrome). Finally, the apnea and vital signs monitor for infants provides a crib that can be controlled digitally or through an interface with a mobile device, this interface will make possible to change the inclination of the crib, helping to prevent reflux in babies. The system sends images and sound from the crib to the to the parents mobile device for a greater peace of mind, besides the invention keeps an event history and environmental conditions record.
