title: [Possibility of an incorrect connection between certain respiratory filters and the expiratory segment of the Ambu-A non-rebreathing valve].
abstract: Several models among the contemporary disposable bacterial filters, heat and moisture exchangers can be inadvertently inserted into the expiratory port of the Ambu A nonrebreathing valve. Such a misconnection, which does not allow expiration, is made possible because of the respective sizes of the connection ports of the devices. International standards and French regulations specify neither the internal diameter of the expiratory port of the nonrebreathing valves, nor the external diameter of the circuit connecting port of the respiratory filters.
