"The RB 004 Gauge Rail Clamp is an accessory to the NS Series Vacuum/Pressure Gauges. The RB 004 is used to securely mount Gauges with a rear 1/4"" NPT thread to rails. For use with Fairfield-style rails only."
A mechanical device designed to provide a visual indication of a patient's airway pressure during ventilation. It is typically contained in a clear housing marked with a pressure scale [e.g., 5 to 60 cm H20 (hPa)], and has a spring-loaded indicator that, in resistance to the expiratory flow of air, registers the airway pressure. It connects to the manometer port of a variety of ventilation devices such as a resuscitation bag, hyperinflation bag, continuous positive airway pressure (CPAP) mask, or a CPAP circuit. It may be used in a healthcare setting (including ambulatory) or in the home. This is a single-use device.
