A head gatch alarm system reduces medical risk for aspirational pneumonia when an angle of the head gatch section is outside a predetermined range. The system includes an inclinometer and a pump. The inclinometer is attached to the head gatch section for sensing an angle of the head gatch section. The inclinometer includes an RF receiver and RF transmitter for sending and receiving signals to a pump. An alarm or other means for alerting a medical professional is in communication with the inclinometer or the pump. The pump includes an RF transmitter and RF receiver for two way RF communication between the pump and the inclinometer. In operation, the alarm is triggered and the pump is turned off when the head gatch section is positioned outside a predetermined range.
