1. A tracheal connector for interfacing between a patient and a gases flow source, comprising:
a patient port;
an outlet end comprising a flow restrictor;
an inlet port fluidly coupled to the gases flow source and configured to receive a flow of gases from the gases flow source;
wherein the flow restrictor restricts expiratory flow is configured to produce PEEP of at least 1 cmH2O when flow is 50 liters per minute;
wherein the patient port and the outlet end are coaxial; and
wherein the inlet port is disposed at an angle that forms an obtuse angle with the patient port.
