Quick Operation Guide (Including Parameters of S/T(30) Mode)

Auto CPAP/APAP Machine

Parameters of S/T(30) Mode

  • S/T(30) Mode is an important therapy mode and many of its parameters can be set in the same way in other therapy modes. 

  • When S/T Mode (Spontaneous/Timed Mode) chosen, iBreeze BPAP can monitor how many spontaneous breaths a user takes per minute. If the user doesn’t take enough spontaneous breaths, the machine will add pressure to help him/her breathe.

  • S/T(30) Mode is a therapy mode in which air pressure can go up to 30 cmH2O. 

IPAP: 4-30cmH2O (≥EPAP)

Value of air pressure for inhaling (inspiratory positive airway pressure).

 

EPAP: 4-30cmH2O (≤IPAP)

Value of air pressure for exhaling (expiratory positive airway pressure).

 

Rise Time: 100-900ms(0.1-0.9s) 

Time the machine takes to change from EPAP to IPAP.

 

Vt: ON (200-2000ml) / OFF 

It's to switch on EVAPS which allows IPAP to change automatically, providing the user with optimal levels of air pressure and maximum comfort while maintaining a fixed target tidal volume his/her therapy needs (the tidal volume / Vt can be chosen from 200 to 2000ml).

 

When Vt is ON, the IPAP value can’t be set manually because IPAP will auto change and not be a fixed value. Two other parameters need to be set, which are IPAP Max, IPAP Min. The value of the changing IPAP is limited between IPAP Max and IPAP Min.

 

When Vt is OFF, the IPAP value can be set manually and will become a fixed value during therapy, and parameters of IPAP Max and IPAP Min can’t be chosen. 

 

IPAP Max: 4-30cmH2O (≥IPAP Min) 

Maximum value for IPAP. Can be set only if Vt is ON (EVAPS is ON).

 

IPAP Min: 4-30cmH2O (≤IPAP Max) 

Minimun value for IPAP. Can be set only if Vt is ON (EVAPS is ON).

 

Ti: 0.3-4s 

Time the machine takes to add pressure to help the user breathe in. Kicks in when user’s respiratory rate falls below the backup breathing rate (BPM / BUR).

 

F: 5-50 BPM 

F / Backup breathing frequency / Breaths per Minute (BPM) / Backup Rate (BUR). If the user's respiratory rate falls below the value of backup rate, the machine will add pressure to prompt him/her to breathe.

 

Ti Control: ON/OFF 

Able to set the inspiration time for the user’s spontaneous breathing if Ti Control is ON. If the inspiration time for spontaneous breathing goes outside the set range (Ti Min to Ti Max), the machine can change the timing of IPAP/EPAP delivery to help the user breathe normally. 

 

If Ti Control is OFF, the machine will not intervene in user's spontaneous inhalation time.

 

Ti Max: 0.1-4s(≥Ti Min) 

The longest period of time for the user’s spontaneous inhalation the machine allows. Can be set only if Ti Control is ON.

 

Ti Min: 0.1-4s(≤Ti Max) 

The shortest period of time for the user’s spontaneous inhalation the machine allows. Can be set only if Ti Control is ON.

 

I Trigger: 1-5, Auto

Parameter for adjusting the machine’s sensitivity to responding to user’s spontaneous inspiration. If a higher number selected, IPAP becomes more likely to be triggered. The default value is 3 and this value can be chosen by most users.

 

E Trigger: 1-5, Auto

Parameter for adjusting the machine’s sensitivity to responding to user’s spontaneous exhalation. If a higher number selected, EPAP becomes more likely to be triggered. The default value is 3 and this value can be chosen by most users.

 

Press ADJ: 1-3

Parameter for controlling how quickly IPAP can auto adjust to maintain a target tidal volume (Vt) the user needs. The higher the number is, the faster IPAP can auto adjust. The default value is 2 and this value can be chosen by most users. Can be set only if Vt is ON. 

 

  • The default values of I Trigger, E Trigger, Press ADJ can be used by most customers. 

  • Ti-Control and Ti are two different parameters that may confuse some doctors or users. Ti-Control is to let the machine control the timing for a user’s inhalation so the duration of his/her spontaneous inhalation is limited within certain range (Ti Min-Ti Max); Ti is how much time the machine takes to add pressure to help a user inhale when his/her spontaneous respiratory rate is below normal. 

  • EVAPS (Efficient Volume Assured Pressure Support) allows IPAP to change automatically while maintaining a target tidal volume the user needs, providing the user with maximum comfort. This type of advanced technology is also known as AVAPS (by Philips) and another type of very similar technology is iVAPS (by ResMed).
