B.L.S. Systems Limited 4000-PVC Disposable PEEP valve with converter

The reusable BE 30-142 is designed for use with ventilators, anesthesia machines, resuscitators, and other systems where PEEP or CPAP is required. A threshold-like resistance is applied after active exhalation. The PEEP valve prevents the exhalation pressure from dropping below a pre-determined value. PEEP ranges are adjustable from 3 to 20cm of water. Maximum PEEP can vary +/-10%. Objectives of PEEP therapy: 1) increase functional residual capacity by maintaining a positive pressure throughout the ventilatory cycle - improves gas distribution,2) aid in the prevention of atelectasis via aveolar stinting, 3) decrease in the inspired oxygen fraction (FiO2) is an advantage, 4) help in the stabilization of flail chest condition, and 5) monitor tidal volume by connecting a spirometer to the outlet port.
