Ventilation with a self-expanding bag,using a face mask, is one of the basic ways to secure patients ventilation who do not breathe spontaneously. A self-expanding bag is part of every resuscitation equipment in each hospital ward and clinic.

The face mask can be held with one hand - EC-clamp technique, or with two hands, where two methods can be used: C-E technique, or V-E technique. The V-E technique has a higher probability of successful ventilation and less hand fatigue.

One hand ventilation technique: EC-clamp.

Two handed C-E technique.

Two handed V-E technique.
