Two useful new respiratory products
Sometime in the 1780s the French scientist Jacques Charles’s noted that at constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature on the absolute temperature scale. Or, put more simply, the gas expands as the temperature increases. This is known [...]
End tidal carbon dioxide monitoring in cryonics
The best non-invasive indicator of cardiac output and oxygenation during cardiopulmonary support (CPS) is end tidal carbon dioxide (ETCO2). ETCO2 is the partial pressure of carbon dioxide (CO2) at the end of an exhaled breath. Until recently, cryonics standby kits were equipped with disposable colorimetric ETCO2 detectors. Some limitations of the disposable ETCO2 detectors [...]
