1. A system of providing fluid to a user, comprising:
- distensible tubing;
a flow controller coupled to the tubing and configured to control a flow of fluid through the tubing; and
a fluid flow adjustment module connected to the tubing and the flow controller, the module being configured to measure pressure changes in the tubing during a single inhalation and control the flow controller to provide an optimum amount of the fluid through the tubing based on the measured pressure changes during the inhalation.

5. A system of providing oxygen to a user, comprising:
-
distensible tubing connected between an oxygen source and the user to provide an amount of oxygen to the user; a flow controller coupled to the tubing and configured to control the amount of oxygen through the tubing; a pressure sensor connected to the tubing between the flow controller and the user; and a microcontroller coupled to the pressure sensor, the microcontroller being configured to; receive pressure signals provided by the pressure sensor, wherein the pressure signals are detected from differential pressure in the tubing, detect the start of a breathing event from the user based on a first pressure signal, determine the amount of oxygen needed by the user based on a second pressure signal, and control the flow controller to adjust the amount of oxygen flow to the user based on the second pressure signal. - View Dependent Claims (6, 7, 8, 9)
