My former resident Seth Trueger (@mdaware) is missing having waveform capnographs at every resuscitation bedside. He is looking for a stand-alone unit for his department to purchase.
First person I suggested he reach out to is prehospital master, Christopher Watford who wrote back this,
As far as handheld goes, Nellcor makes the N-85 which has both EtCO2 (quantitative and waveform) and SpO2. I think new they're around $4k. BCI offers the Capnocheck, which is good too, but I think has more options and is pricier. Oridion has the priciest, but a lot of prehospital and inhospital cardiac monitors use their technology.It also uses semi-standard adaptors, so you may get lucky with some other section of your hospital using the adaptors. EMS in your area may use it too, potential cost sharing opportunity.We've got EtCO2 built into our Philips MRx's, both our LP12's and LP15's, and all of our Zoll's (E, M, and now the X-series). So we don't really use the handheld units in EMS. You could look into upgrading inhospital monitors, usually its a $2-3k “add on” (basically a software upgrade if you've got the port).Let me know if you need anything else!
