Capnography is the monitoring of the concentration or partial pressure of carbon dioxide (CO 2 ) in the respiratory gases. Its main development has been as a monitoring tool for use during anesthesia and intensive care .
Colorimetric capnography is a qualitative measurement method that detects the presence of carbon dioxide (CO2, a relatively acidic gas) in a given gaseous environment. From a medical perspective, the method is usually applied by exposing litmus paper/film to an environment containing a patient's airway gases (i.e. placing it into their breathing circuit/airway circuit), where it will then ...
Integrated pulmonary index (IPI) is a patient pulmonary index which uses information from capnography and pulse oximetry to provide a single value that describes the patient's respiratory status. IPI is used by clinicians to quickly assess the patient's respiratory status to determine the need for additional clinical assessment or intervention.
Capnography, which involves CO 2 measurements, referred to as EtCO2 or end-tidal carbon dioxide concentration. The respiratory rate monitored as such is called AWRR or airway respiratory rate) Respiratory rate monitoring through a thoracic transducer belt, an ECG channel or via capnography; Neurological monitoring, such as of intracranial pressure.
Using a small amount of inhaled or injected radioactive material called a tracer for visualization, a V/Q scan is a type of nuclear medical imaging that allows for localization and characterization of blood flow (perfusion scan) and measurement of airflow (ventilation scan) within the lungs. [2]
This could mean a return to hybrid popularity. According to recent data from the U.S. Energy Information Administration (EIA) , hybrid electric vehicles were 8.6% of the light-duty vehicle market ...
In colorimetric capnography, the indicator is incorporated in an aqueous matrix that provides a pH just above the indicator's colour change. [4] When exposed to carbon dioxide (CO 2 ), it undergoes a colour change from purple to yellow, because when CO 2 dissolves in the matrix, it forms carbonic acid .
The recall is now Class I, meaning that "there is a reasonable probability that use of the product will cause serious, adverse health consequences or death," according to the Food Safety and ...
