| Question | Answer |
| What is BiPAP | non invasive device that augments pt ventilation |
| What are the 2 levels of pressure | IPAP and EPAP |
| On BiPAP which one is larger | larger on insp ex 12/5 |
| BiPAP is always | spontaneous |
| IPAP | increase the increments of 2 cmH20. used if there is a CO2 problem (ventilation) |
| EPAP | increase in increments of 2 cmH20. Oxygenation problem, similiar to PEEP |
| Spontaneous | pt triggers ALL inspirations which are pressure supported. You set IPAP and EPAP only. Pt determines RR, volume |
| S/T | Pt determines volume, if pt does not breath, cycles to IPAP when time has elapsed.` |
| T | cycles btwn IPAP and EPAP due to time intervals only. PT may take additional OWN breaths. You set IPAP, EPAP, BPM and % IPAP (like control mode) |
| CPAP mode | pressure is set on continous, pt breaths on it's own, pt is control of RR and volume, set EPAP only |
| indications for BiPAP | resp failure, post surgical, hypoxemia due to hypoventilation, sleep apnea, vent muscle fatigue, upper airway obstruction, post extubation difficulties |
| contraindications for BiPAP | pre existing pneumothorax, hypotension, pre existing bullous lung disease (emphysema), nose bleeding, aspiration, sinusitus |
| side effects of BiPAp | pressure ulcers, claustophobic, eye irratiation |
| What do you adjust IPAP for | ventilation problems |
| What do you adjust EPAP for | oxygenation problems |
| Benefits of BiPAP | can talk, non invasive, infection risk decreased, works in presence of leaks, |
| GOALS of BiPAP | avoid intubation, pt mobility improvement, decrease VAP, improve gas exchange |
| IPAP initial setting | 8-12 cmH20 |
| EPAP initial setting | 3-5 cmH20 |
| Initial setting for oxygen | match pt's or titrate to obtain acceptable PaO2 |
| initial settings for BPM | 2-5 less than pt's spontaneous rate |
| intitial settings for % IPAP | usually 33-50% to deliver 1:2 or 1:1 |
| If there is an increase in CO2 what do you do | adjust IPAP to create greater pressure differences between IPAP and EPAP (this increases alveolar ventilation) |
| What to do if you have hypoxemia | increase level of EPAP |
| IF unit stops and starts | check power cord, check connection |
| if there is no air flow from unit | check voltage selector switch, possible internal problem |
| unit runs but light not activated | replace light |
| How many sets on BiPAP | 2, CPAP and S/T |
| What do you want to set RR on | 4-40 bpm |
| What do you want to set IPAP on | 4-40 cmH20 |
| What do you want to set EPAP on | 4-20 cmH20 |
| What does the exhalation port do | directs air. Exhale goes through port so pt doesn't rebreath their CO2 |
| What does the exhalation port test do | anaylyzes leak rate of exhalation port. |
| Pt flow triggered breaths are | flow cycled |
| Time triggered breaths are | time cycled according to the set insp time |
| How should the mask fit | from the bridge of the nose to just below the nares... make sure the mask rests above the upper lip |
| What is the whisper swivel | designed to exhaust CO2 from pt's circuit |
| Pt's tidal volume should be | 20% greater than what they are doing |
| Pt with chronic hypercapnia IPAP should | be adjusted to maintain an acceptable pH NOT normalize the PaCO2 |
