The Tongue Sucker may be applied in a first aid situation as well as in the controlled hospital environment.
It is designed to address the following problems:

Blocked airway
An unconscious casualty or patient under anaesthetics loses muscle tone and, as a result, their tongue can fall to the back of their throat, blocking their airway. Properly opening and maintaining the airway of an unconscious casualty or patient is critical.

In the area of first aid the Tongue Sucker may also aid with the following:

Reluctance or inability to perform CPR
Conventional cardiopulmonary resuscitation or CPR involves a combination of chest compressions with rescue breathing (mouth-to-mouth ventilation), which could, in some cases ,double a patient’s chances of survival. Studies show however that only 1 victim in 3 will receive bystander CPR because rescuers are untrained, were trained but have forgotten or are afraid of intimate contact with the casualty.
