1. An apparatus to reduce respiration of a perishable commodity in a low pressure chamber, comprising:
the low pressure chamber, a gas measurement and management system, a computer processor and a memory, and a respiratory management module in the memory to manage respiration of the perishable commodity in the low pressure chamber; wherein
to manage respiration of the perishable commodity in the low pressure chamber, the processor is to execute the respiratory management module and the respiratory management module is to use the gas measurement and management system and the low pressure chamber to:
obtain a total absolute pressure in the low pressure chamber, obtain at least one of a carbon dioxide partial pressure in the low pressure chamber or an oxygen partial pressure in the low pressure chamber;
reduce the total absolute pressure to a low absolute pressure, wherein the low absolute pressure is above an anaerobic compensation point for the perishable commodity;
determine a respiration of the perishable commodity in the low pressure chamber at the low absolute pressure; and
in response to the respiration of the perishable commodity in the low pressure chamber, control a gas composition and the low absolute pressure in the low pressure chamber to reduce aerobic respiration of the perishable commodity and avoid anaerobic respiration of the perishable commodity in the low pressure chamber.
