Informationen:

This BiPAP unit provides bi-level positive airway pressure, through a nasal or nasal / oral mask, to assist patient ventilation. An integral flow transducer senses whether the patient is inhaling or exhaling by constantly monitoring the amount of air flowing through the system. The system then provides the appropriate amount of positive air pressure for the function, i.e., more pressure during inhalation (IPAP), less pressure during exhalation (EPAP). The unit is available in four models: BiPAP S, BiPAP S/T, BiPAP S-D, BiPAP S/T-D. The BiPAP S unit offers two modes of operation: • CPAP (Continuous Positive Airway Pressure) - When the control is set to either IPAP or EPAP, the unit provides continuous pressure at the level you set for that function. • SPONTANEOUS - The unit cycles between inhalation (IPAP) and exhalation (EPAP) levels as triggered by patient breathing. The BiPAP S/T offers four modes of operation: • CPAP (Continuous Positive Airway Pressure) - When the control is set to either IPAP or EPAP, the unit provides continuous pressure at the level you set for that function. • SPONTANEOUS - The unit cycles between inhalation (IPAP) and exhalation (EPAP) levels as triggered by patient breathing. • SPONTANEOUS/TIMED - As with the SPONTANEOUS mode, the unit cycles between IPAP and EPAP levels as sensed from patient breathing, but if the patient does not inhale within a preset time interval, the unit cycles to IPAP. The time interval is determined by the BPM (breaths per minute) setting on the control panel. • TIMED - The unit cycles between IPAP and EPAP levels at preset time intervals, determined by the BPM and % IPAP (percent of breath cycle spent in IPAP settings on the control panel). The BiPAP S-D unit offers the same operating modes as the BiPAP S, but all functions can be controlled by a Detachable Control Panel (DCP). In addition, the following DC analog output signals are provided for a recorder or oscilloscope: • P (Pressure) - The signal from the internal pressure transducer indicates IPAP and EPAP levels (in cm H20 at the measure point in the patient circuit). • Vt (Estimated Tidal Volume) - Signal from the internal flow transducer indicates volume of air (in liters) inhaled or exhaled with each breath during quiet breathing. • V (Total Flow Rate) - The signal from the internal flow transducer indicates total air flow rate (in L/ min) through the unit to the patient circuit. Total air flow consists of the air flow necessary to satisfy circuit leaks (V|eak), and patient breathing (Vest). he BiPAP S/T-D unit offers the same operating modes as the BiPAP S/T, but all functions can be controlled by a DCP. In addition, it provides the same recorder output signals ( VT,7tot Vest and P) as the BiPAP S-D. °' * ’ The Airway Pressure Monitor is designed to supplement patient monitoring during ventilation with the BiPAP S/T-D System. Its purpose is to notify medical personnel and/or user of undesirably LOW (as in a disconnect situation) or HIGH pressures at a specific point in the breathing cycle.
