Either ‘dry drowning’ or ‘secondary drowning’ occur when water somehow does not find a release and gets trapped in the respiratory tract. In the case of dry drowning, airway spasms are created by inhaled water without even reaching the lungs. In the case of secondary drowning, the inhaled water goes into the lungs which can potentially cause pulmonary edema. As a consequence, the person faces difficulty in breathing as the body fails to get enough oxygen. This can cause death even after days of the incident of inhaling water.
