Frequently Asked Questions:

How is PEEP set with an LTV circuit without PEEP?

29657-001 is a patient circuit without PEEP.1 On the LTV 1200 and LTV 1150, PEEP is set with the PEEP control button and Set Value knob, range 0 to 20 cm H2O.4

Which LTV circuit is for adults and which is for pediatrics?

The 22 mm patient circuit is the adult circuit, for patients over 20 kg (44 lb).3 The 15 mm patient circuit is the infant and pediatric circuit, for 5 kg to 20 kg (11 lb to 44 lb).3 For other sizes, see all ventilator circuits.

How does the LTV ventilator circuit connect?

On the LTV 1200 and 1150, connect the main breathing tube to the 22 mm outlet port on the right side of the ventilator, the two exhalation flow transducer sense lines to the Flow Xducer ports, and the exhalation valve drive line to the Exh Valve port.4 The sense line fittings are non-interchangeable Luer fittings.4

How do I leak test an LTV circuit?

Attach all circuit accessories, connect the circuit to the ventilator, occlude the proximal end of the circuit with a gloved hand or a 4 x 4 gauze pad, and run the Leak Test from the menu after the 60 second warm up.4 The test fails if flow through the flow valve is greater than 1 L/min.4

Can the proximal sense lines be removed from the wye?

No. Do not remove the proximal sense lines from the patient wye.4 Orient the patient wye so the proximal sense lines point up during operation.4

How long is the LTV 29657-001 circuit, and which LTV ventilators is it for?
