1. A monitoring system for monitoring placement of a tracheotomy tube that has been passed through a tracheostomy formed in the neck of a patient, the system comprising:
a monitoring device configured to directly and removably attach to the tracheotomy tube, the monitoring device including a skin sensor solely configured to detect the electrical conductivity of the skin of the patient's neck and, therefore, detect whether the sensor is or is not in direct contact with skin of a patient's neck, wherein the tracheotomy tube is correctly placed when such direct contact is detected.
