1. A ventilator console comprising:
an inhalation port via which gas is delivered to the patient;
an exhalation port via which gas exhaled from a patient is received;
a console sampler configured to sample pressure or flow at the exhalation port;
at least one sensor configured to sense at least one of pressure and flow velocity; and
one or more external control ports configured to provide an interface for flow or pressure communication between the at least one sensor and a tube connected to a patient circuit, wherein at least one external control port of said one or more external control ports comprises a three-way valve,
wherein the three-way valve comprises a common port, and wherein the three-way valve is connected to the at least one sensor via the common port and is configured to toggle between the console sampler and the at least one external control port and thereby toggling between sampling at the exhalation port and receiving a sample through the at least one external control port, wherein the toggling is manually actuated based on pushing or releasing the three-way valve against a spring force.
