Pulse Oximeters and Capnographs:

Pulse oximeters and capnographs are medical devices used to monitor different aspects of respiration and oxygenation. A pulse oximeter measures oxygen saturation levels in the blood and pulse rate, while a capnograph measures carbon dioxide levels in exhaled breath and respiratory rate. Pulse oximeters are non-invasive and widely used in various healthcare settings, while capnographs can be invasive or non-invasive and are primarily used in operating rooms and ICUs. Both devices provide valuable information about respiratory function and are often used together to assess a patient's overall respiratory status.
