Perfecting the science of precise pressure.
Introducing
KPAP™(Kairos Positive Airway Pressure)
For the first time, a radically new pressure algorithm demonstrates improved patient comfort by delivering the optimal inspiratory and expiratory pressure...
at the right time.
Kricket™ and KPAP™: Under 510K review. Not available for sale in the U.S. Any claims associated with KPAP™ have not yet been reviewed by FDA.
Previous efforts to address the condition while making therapy comfortable and tolerable have fallen short.

EPR
-
Lowering IPAP
makes inspiratory pattern and flow more like a patient’s normal respiration. -
Lowering EPAP
reduces expiratory work of breathing. -
Yet returning pressure to optimal levels when appropriate.
We need to make therapy be more like natural breathing.
Optimizing pressure
delivers a better way.
Timing is everything.
KPAP™
- Inspiration: Pressure dropped 2cm and then 3cm H2O yielding a pressure 5cm H2O below therapeutic pressure.
- Expiration: Pressure down at initiation of expiration and stays down through most of the expiratory cycle.
- End Expiration: Pressure returned to therapeutic levels to assure optimal pharyngeal patency and lung volume.
KPAP™ preferred to CPAP by virtually all patients
KPAP™ Comfort Study Results
- 150 patients with recently diagnosed, untreated OSA with an AHI>10.
- Prior to initiation of PAP were exposed to and asked to compare for comfort:
- CPAP at 9 and 13cm H2O
- KPAP™ at 9 and 13cm H2O with various pressure drops
- Outcome:
- Patient selects each time whether CPAP or KPAP™ is more comfortable in blinded manner

KPAP™ delivers equivalent therapeutic efficacy to standard CPAP
KPAP™ Efficacy Trial
- 50 patients with documented OSA on stable APAP with >6 hours per night adherence.
- Reported to the sleep lab for a full night PSG. In random order the patient slept:
- Half the night on CPAP set at the P95 pressure determined from the PAP device at home.
- Half the night on KPAP™ set at the same P95 with a 2cm then 3cm H2O (total 5 cm H2O) drop during inspiration and a return to the P95 pressure approximately half way through expiration.
- Comparisons of CPAP versus XPAP included:
- AHI 3a (3% fall in Sp02 or arousal to score hypopneas)
- AHI 4 (4% fall in Sp02 to score hypopneas)
- AHI in REM and NREM sleep
- AHI supine and lateral


In conclusion:
- KPAP™ has the same efficacy in treating OSA as standard CPAP despite dropping the pressure by 5cm H2O.
- Patients initiating PAP therapy virtually all found KPAP™ more comfortable than CPAP.
- We now need to conduct adherence trials comparing KPAP™ (with auto-titration) to standard APAP.
- 6-week randomized crossover trial with adherence as the primary outcome.
