Respironics focus user manual

Compact and lightweight, the BiPAP Focus System provides features that make delivery of noninvasive ventilation easy and effective. This feature assures optimum triggering and cycling sensitivity throughout changing breathing patterns and leaks. It also eliminates the need for a perfect seal of the patient interface and constant adjustment while promoting patient-ventilator synchrony.

Large Use Interface - Designed for the hospital environment, the user interface is easy to use. It allows the practitioner to easily and quickly adjust patient care settings. Patient Parameters Display - This valuable feature conveniently allows the practitioner to view all patient parameters at once. Pressure Bar Graph - Quickly and clearly indicates patient breaths and pressure ranges.

Back-up Battery - An integral backup battery system maintains patient ventilation in the event of an interruption in power. This safety feature also provides a convenient method for intra-hospital patient transport from one care area to another with uninterrupted ventilatory care. Toggle Navigation. Sign in.

Battery compartment White-keyed battery cable connector Battery pack. Replace the battery pack in the battery compartment, close the cover, and tighten the screws. Connect the power cord. The unit also has an internal battery as a backup power source. The internal battery can run the system for 45 minutes at default settings see Specifications on page 61 for default settings. Connect battery during initial setup see pages 8 and 9.

NOTE: If the unit is being set-up for the first time out of the box , it is recommended that the unit gets a full battery charge. This also applies after the unit has been stored for 2 weeks or longer. If a error code is displayed, contact Service. The nurse call station alarm is activated when the ventilator is turned OFF, or put into Standby, an alarm occurs, or a system error occurs.

The nurse call station alarm is deactivated when all active alarms are silenced or auto-reset. Most nurse call station systems require only normally open NO or normally closed NC connections.

NO and NC nurse call station cables are available from Respironics. See Accessories on page 81 for cable ordering information. See Specifications on page 61 for pinout information. The communication and USB ports allow service technicians to upgrade system software. To avoid introducing foreign matter into the system, a reusable air inlet filter must be installed. See Care and Maintenance on page 55 for information on how to clean the reusable air inlet filter.

An additional ultra-fine disposable filter is also recommended for enhanced particulate filtering. Simultaneously press and hold the Alarm Reset and Alarm Silence keys. The Menu screen shown in Figure 9 will appear:. After selecting the desired language, the unit will display the message below and will power off automatically after 5 seconds. The BiPAP Focus System patient interface Figure 13 includes: Patient interface nasal or full face mask Breathing circuit tubing Proximal pressure line this line is not used, but should be terminated on the output port mounting post to avoid introducing a leak Bacteria filter Humidifier optional Connecting the Pressure Tube and Filter Connect the pressure tube and filter in the following order: 1.

The displayed pressure compensates for the pressure drop due to the BiPAP Vision single patient use circuit and the bacteria filter see Accessories on page 83 for ordering information. Connecting Supplemental Oxygen If required, connect supplemental oxygen to the patient circuit as shown Figure Bleed in oxygen at the outlet of the BiPAP Focus System, using Respironics-supplied oxygen enrichment adapter and bleed-in safety valve see Accessories on page Table 1 shows the potential range of oxygen concentration for given tidal volume, supplemental oxygen flow, and pressure values.

Substantial leaks around the patient interface can reduce the expected oxygen concentration levels. Use this information for reference when beginning oxygen therapy and adjust oxygen flow gradually to meet patient oxygen needs.

This test is recommended and may be useful for initial setup or following storage periods. Follow these steps to perform a pre-operational check: 1. NOTE: If the ventilator has been in storage for 2 weeks or longer, allow the internal battery to charge for at least 30 minutes before performing the following step.

If a Batt. Charge Failure alarm occurs, the battery may be fully depleted. A re-charge is recommended before proceeding. If the battery does not begin to charge after one hour and the Batt. Charge Failure persists, contact customer service for a replacement battery. Once the system begins normal operation, disconnect the power cord from wall power.

The audible alarm sounds beeps every 10 seconds alerting the user that unit is running on the internal battery. Reconnect AC power. Enter CPAP mode with a patient circuit attached and allow the ventilator to deliver gas for more than 15 seconds. Reenter CPAP mode, clear any alarms, and connect a nurse call station cable.

The nurse call station alarm activates. Pre-Operational Check is complete. Perform the pre-operational check as required. Select the appropriate settings. See "Normal Operation" for more information. Select a mask See Accessories on page Attach to the patient circuit. NOTE: Direct the exhalation port gas-flow away from the patient.

This helps to maintain patient comfort. The system is now ready to be connected to the patient. If the patient does not spontaneously breathe within the cycle time determined by the Rate setting, the ventilator delivers a timed breath at the set level of IPAP.

The I-Time setting determines the duration of each timed breath. Figure Cycle IPAP. The Ramp Time and Ramp Start settings Figure 16 allow the ventilator to begin at a reduced pressure the Ramp Start setting then gradually increase the pressure breath by breath to the prescription pressure CPAP or EPAP , allowing the patient to fall asleep more comfortably.

Leak Estimation The system monitors the total flow in the patient circuit and estimates patient leak using leak estimation algorithms. Because no preset sensitivity threshold can ensure patient and machine synchrony with changing breathing efforts and circuit leaks, the BiPAP Focus continuously tracks patient breathing patterns and automatically adjusts its sensitivity thresholds to ensure optimum sensitivity as breathing patterns or circuit leaks change.

The volume trigger threshold is 6 mL of accumulated patient inspiratory volume. The Shape Signal algorithm Figure 17 continuously tracks patient inspiratory and expiratory flow and adjusts the spontaneous trigger and cycle thresholds for optimum sensitivity.

The shape signal is a shadow image of the patients actual flow and functions as a sensitivity threshold at either inspiration or exhalation. When the patients flow rate crosses the shape signal, the system changes pressure levels. This causes the shape signal to be slightly behind the patients flow rate.

A sudden change in patient flow causes the shape signal to be crossed, causing the pressure level to change. The spontaneous expiratory threshold SET algorithm Figure 18 raises the threshold in proportion to the inspiratory flow rate for each breath. Flow reversal: As flow begins to decrease during IPAP, a flow reversal can occur due to a large leak around the mask or because the patients mouth is open.

When the system senses this flow reversal, the unit automatically cycles to EPAP. Table 2 summarizes the functions of the front panel elements. Each key press restarts the 2-minute interval.

The indicator lights yellow when alarm silence is active. Alarm presilence: press when no alarm is active for two minutes of silence. AC indicator lights green to show that the system is powered by AC mains power.

Press OK to remove this pop-up before proceeding to the next step. When the internal battery is fully charged, the Battery Back-up feature allows the unit to continue operation for a limited time in the event of mains power loss or during intra-hospital transport.

If loss of mains power occurs, the unit will automatically switch to operate from the internal battery and will generate the Loss of AC alarm this alarm can be silenced, see Alarms on page The internal battery is NOT intended to serve as a primary power source. When the BiPAP Focus estimates that there are 10 minutes of internal battery power remaining, the unit will generate a silenceable Low Battery alarm. Mains power should be reconnected immediately to avoid loss of power.

When the BiPAP Focus estimates that there are 2 minutes of internal battery power remaining, the Battery Depleted alarm non-silenceable will occur. Mains power must be reconnected immediately to avoid loss of power to the ventilator. CAUTION: When using the Focus for patient intra-hospital transport, ensure that the DC power supply and power cord are also transported with the unit should the battery become depleted.

Battery Operating Time The amount of time the ventilator will operate on the internal battery depends primarily on the machine settings being used. The following table shows the approximate internal battery life expectancy for a fully charged battery. The battery will automatically charge when the unit is connected to mains power AC via the DC power supply and when the power switch on the back of the ventilator is in the ON position.

The charging cycle operates in Normal Mode and in Standby Mode. Battery charge time is typically less than 5 hours, but can be longer depending on environmental conditions primarily temperature. It is important to maintain a fully charged internal battery in case of a mains power outage. A fully charged battery will deplete within 3 months if unused and not charged.

Battery Care If the number of battery powered operations is greater than per year, the battery should be replaced every six months. If the number of battery powered operations is less than per year, the battery should be replaced every year. Let us know how we can help. Inquire with a Philips healthcare sales rep Sales inquiry.
