Bi-Level Positive Airway Pressure (BiPAP) S/T with Humidifier is a type of respiratory therapy equipment used to treat sleep apnea and other respiratory disorders. The "S/T" in the product name refers to the "Spontaneous/Timed" mode, which means that the machine can be set to deliver breaths either when the user triggers it (spontaneously) or at regular intervals (timed). The humidifier is a separate unit that can be attached to the BiPAP machine to add moisture to the air being delivered to the user. The BiPAP S/T with Humidifier is made by Foras, a Turkish company that specializes in medical equipment and supplies. The specific features and specifications of this product may vary, so it is recommended to check with the manufacturer for more detailed information.
