An extracorporeal blood circulation system monitors blood level in a reservoir which temporarily stores the blood. A memory storage unit stores blood pressure measurements from a pressure sensor monitoring a blood pressure within a tube unit conveying blood from the reservoir relative to atmosphere. A processing unit that detects a height of a top surface of the blood stored in the reservoir based on changes in the blood pressure measurements and a conservation of mechanical energy of a blood flow inside the tube unit. A notification is generated if an abnormality is detected in the height of the blood in the reservoir.

Disclosed herein are various techniques and devices for detecting a level of fluid within a fluid collection receptacle. In one embodiment, a pressure sensor connected to a bottle is provided. The pressure sensor detects air pressure in the bottle as the bottle is filled with a liquid and provides information to determine a volume of the liquid in the bottle.

A dive computer system that includes a primary power source and a console, located remotely from the power source. The console includes a display screen configured to be readable underwater. The primary power source is connected to the console via a cable. The console does not include a connection for a gas hose. In certain embodiments the dive computer includes a secondary power source, while in further embodiments the dive computer has a color display.

A reduced pressure treatment system is provided that includes a canister that is fluidly connected to a tissue site and is configured to receive fluid drawn from the tissue site under the influence of a reduced pressure. A reduced pressure source provides the reduced pressure and is fluidly connected to the tissue site by a fluid communication path, which may include a source conduit, the canister, and a target conduit. A sensing device communicates with the source conduit and is configured to sense a pressure in the source conduit. A valve communicates with the source conduit and is configured to vent the reduced pressure. A processing unit communicates with the sensing device and the valve and is configured to open the valve for a selected amount of time, determine a decay of reduced pressure, and determine a fill status of the canister based on the decay of reduced pressure.
