IPI integrates four major physiological parameters provided by a patient monitor, using this information along with an algorithm to produce the IPI score. The IPI score is not intended to replace current patient respiratory parameters, but to provide an additional integrated score or index of the patient ventilation status to the caregiver.
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 ...
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.
Excretion of carbon dioxide is also impaired, but a rise in the arterial partial pressure of carbon dioxide (pCO 2) is very uncommon because this leads to respiratory stimulation and the resultant increase in alveolar ventilation returns paCO 2 to within the normal range.
Hypercapnia (from the Greek hyper, "above" or "too much" and kapnos, "smoke"), also known as hypercarbia and CO 2 retention, is a condition of abnormally elevated carbon dioxide (CO 2) levels in the blood.
Various other methods to measure respiratory rate are commonly used, including impedance pneumography, [4] and capnography which are commonly implemented in patient monitoring. In addition, novel techniques for automatically monitoring respiratory rate using wearable sensors are in development, such as estimation of respiratory rate from the ...
The normal range for pH is 7.35–7.45. As the pH decreases (< 7.35), it implies acidosis, while if the pH increases (> 7.45) it implies alkalosis. In the context of arterial blood gases, the most common occurrence will be that of respiratory acidosis. Carbon dioxide is dissolved in the blood as carbonic acid, a weak acid; however, in large ...
