    Intended Use

    To provide visual indication of a patient's airway pressure during ventilation. It may be attached to the manometer port or proximal port on ventilation devices such as resuscitation bags, hyperinflation bags, CPAP mask, or CPAP circuits, For patients that the clinician desires to monitor or measure airway or circuit pressure, including neonates to adults. Home. Physician office, Hospital, Sub-acute Institutions, Emergency services or anywhere measurement of airway pressure is desired.

    Device Description

    The Besmed disposable pressure manometer is a means of providing visual indication of patient airway pressure during ventilation. The device consists of: 1. A flexible nipple for attachment to a sampling / pressure port. 2. Clear housing with a printed pressure scale 3. A float with indicator 4. Spring. When positive pressure is present in the ventilation device, the manometer displays the pressure in the "circuit". The proposed design incorporates a calibrated spring, which has demonstrated reasonable accuracy over the expected clinical pressure range - 0-60 cm H2O. Besmed intends offer three (3) models / styles of their disposable pressure manometer. They are identical in design, function and materials. The differences are: Pressure range. 0 0 60 cm H2O 0 40 cm H2O · Rationale some devices which may use a pressure manometer do not produce as high a pressure and the user often would like a lower limit pressure design Note the accuracy and performances are identical . Indicator strip . O All models have the pressure range embossed on the housing o A color strip / indicator may also be included to indicate the pressure. It is a single patient, disposable, packaged non-sterile device.
