Abstract
For anesthesiologists working in high-income countries (HICs), pulse oximetry and capnography have become an indispensable part of safe anesthetic practice. In 2023, it is inconceivable that HIC anesthesia providers would feel comfortable providing anesthesia without the benefit of these devices. Pulse oximetry has also become a standard of care in many low- and middle-income countries (LMICs) but anesthesiologists do not have access to capnography. It is time to close the capnography gap.
