Carbon dioxide is a by-product of food metabolism and in high amounts has toxic effects including: dyspnea, acidosis and altered consciousness. [8] Arterial blood carbon dioxide tension. P a CO 2 – Partial pressure of carbon dioxide at sea level in arterial blood is between 35 and 45 mmHg (4.7 and 6.0 kPa). [9] Venous blood carbon dioxide tension
Hyperoxia is the state of being exposed to high levels of oxygen; it may refer to organisms, cells and tissues that are experiencing excessive oxygenation, [1] or to an abnormally high oxygen concentration in an environment (e.g. a body of water).
ISO 22000 is the most popular voluntary food safety international standard in the food industry with 51,535 total number of sites (as per the ISO Survey 2022).The ISO 22000 family are international voluntary consensus standards which align to Good Standardization Practices (GSP) [3] and the World Trade Organization (WTO) Principles for the Development of International Standards.

In healthy lungs where the alveolar dead space is small, Fowler's method accurately measures the anatomic dead space using a single breath nitrogen washout technique. [ 4 ] [ 5 ] The normal value for dead space volume (in mL) is approximately the lean mass of the body (in pounds), and averages about a third of the resting tidal volume (450-500 mL).
This is calculated by dividing the PaO2 by the FiO2. Example: patient who is receiving an FiO2 of .5 (i.e., 50%) with a measured PaO2 of 60 mmHg has a PaO 2 / FiO 2 ratio of 120. In healthy lungs, the Horowitz index depends on age and usually falls between 350 and 450.
CLIP is an analog measurement taking the portion of fulfillment into account using customer commit date as reference date. This intends a usage within a supply chain part with a fixed-period demand pattern (e.g. daily or weekly) and a permanent material flow (e.g. between production and distribution center ), which is later on again split to be ...
Within a product's supply chain, traceability may be both a regulatory and an ethical or environmental issue. [3] Traceability is increasingly becoming a core criterion for sustainability efforts related to supply chains wherein knowing the producer, workers and other links stands as a necessary factor that underlies credible claims of social, economic, or environmental impacts.

Although food engineering is a relatively recent and evolving field of study, it is based on long-established concepts and activities. [1] The traditional focus of food engineering was preservation, which involved stabilizing and sterilizing foods, preventing spoilage, and preserving nutrients in food for prolonged periods of time.
