Ventilator System:

The Respironics BiPAP S/T-D30 device is designed to augment the breathing of a spontaneously-breathing adult patient. Unlike ventilators, it will not completely take over the breathing for the patient, but instead helps a patient who has chronic respiratory failure, difficulty breathing, or obstructive sleep apnea; it is administered via a mask and does not require intubation of the patient. The device automatically synchronizes with the patient’s respiratory pattern, cycling between IPAP and EPAP (breath in and breath out).

This STD30 is completely patient ready and comes on a rolling stand, control panel and airway pressure monitor.

The BiPAP S/T is a low-pressure, electrically driven ventilation system with electronic pressure control. The unit’s pressure controls are adjusted to deliver pressure support for patient ventilatory assistance.

The BiPAP S/T System is primarily intended to augment patient ventilation by supplying pressurized air through a patient circuit. It senses the patient’s breathing effort by monitoring airflow in the patient circuit and adjusts its output to assist in inhalation or exhalation. This assistance is provided by the administration of two levels of positive pressure. During exhalation, pressure is variably positive or near ambient. The inspiratory level is variably positive and is always higher than the expiratory level.

The Respironics BiPAP S/T System responds to changes in patient flow rates that indicate movement to inhalation and exhalation. It can perform reliably in sensing the patient’s breathing efforts, even with the presence of most leaks in the patient circuit. Automatic adjustment of the trigger threshold in the presence of leaks make the System ideal for mask-applied ventilation assistance.

The BiPAP S/T senses air flow in the patient circuit by using a flow transducer in conjunction with the patient air outlet. The flow signal is composed of flow into the patient’s lungs and flow due to leaks in the patient circuit. This flow data is continually processed and adjustments are automatically made to trigger thresholds. The adjustments provide high sensitivity to inspiratory effort and rapid adjustment for changing leaks while minimizing inspiratory pressure lockup or auto-triggering.

The System can operate in the following four modes. In all of the modes, the prescribed setting for each functional control must be determined by the physician/technician based on appropriate patient testing and monitoring of the necessary physiologic parameters.

Airway Pressure Monitor

BiPAP, CPAP, or volume ventilator units can be attached to the optional Airway Pressure Monitor (RPST/AWP), which provides constant analysis of airway pressure and will sound an audible alarm if pressure goes outside preset pressure limits.

Spontaneous (S) Mode

The unit cycles between the Inspiratory Positive Airway Pressure (IPAP) and Expiratory

Positive Airway Pressure (EPAP) levels in response to patient triggering. The patient determines the respiratory rate.

Spontaneous/Timed (S/T) Mode

The unit cycles between the IPAP and EPAP levels in response to patient triggering. If the patient fails to initiate an inspiration, the unit will cycle to IPAP based on a preset interval determined by the Breaths Per Minute (BPM) control.

Timed (T) Mode

The unit cycles between the IPAP and EPAP levels based solely on the timing intervals as determined by the rate (BPM) and inspiratory time (% IPAP) controls. The patient may superimpose spontaneous respirations over the IPAP and EPAP levels.

Continuous Positive Airway Pressure (CPAP)

With the Function Selector Knob set in either the IPAP or EPAP position, the pressure set on the corresponding dial will be delivered continuously.



IPAP: Delivers set pressure continuously

EPAP: Delivers set pressure continuously

Modes: Spontaneous, Spontaneous/Timed, Timed, CPAP

Pressure and Flow Characteristics

Pressure Range: IPAP: 4 cm H2O to 20 cm H2O* at ± 60 L/min flow

EPAP: 4 cm H2O to 20 cm H2O* at ± 60 L/min flow

Pressure controls are coupled so that the unit will not deliver a higher EPAP than

IPAP level when the unit is operated in the S, S/T, or T modes.
