The resuscitator (1) includes a self-inflating squeeze bag (2) having an inlet opening accommodating an inlet valve arrangement (6) adapted to allow inflow of air into the squeeze bag and to prevent outflow of air from the squeeze bag through the inlet opening and an outlet opening accommodating a patient valve arrangement (8) adapted to allow outflow of air from the squeeze bag into the patient valve housing and adapted to prevent inflow of air into the squeeze bag through the outlet opening. The patient valve housing includes a patient connection port (9) for ventilation of a patient and a patient expiration outlet port (10) for outlet of exhaled gas from the patient valve housing to the surroundings. The resuscitator includes a filter arrangement (11) located upstream the outlet opening of the squeeze bag in order to filter air before reaching the patient valve arrangement from the squeeze bag.
