1. A gas flow monitor comprising:
- a housing having a fluid passage, an inlet and an outlet, the fluid passage configured to pass a gas introduced at the inlet to the outlet;
a controller contained within the housing;
a first indicator contained within the housing;
a pressure sensitive switch in fluid communication with the fluid passage, the pressure sensitive switch having a first position indicating that the fluid passage contains at least a threshold pressure of a gas introduced through the inlet and a second position indicating the absence of a threshold pressure of a gas in the fluid passage, wherein the controller is configured to provide a first indication with the first indicator in response to the pressure sensitive switch being in the first position, wherein the housing includes a body member including the fluid passage, a first removable housing member configured to be coupled to the body member, and a second removable housing member configured to be coupled to the body member, the first removable housing member configured to receive the controller and the first indicator, the second removable housing configured to receive a portable power supply, the portable power supply being electrically coupled to the controller and the first indicator.

12. A gas flow monitor configured to be coupled in-line to a gas delivery system configured to convey a regulated amount of gas from a gas source to a patient, the gas delivery system including a first portion coupled to the gas source and a second portion coupled to a fluid dispensing device, the gas flow monitor comprising:
-
a housing having a fluid passage, an inlet and an outlet, the fluid passage configured to pass a gas introduced at the inlet to the outlet, the inlet configured to be coupled to the first portion of the gas delivery system and the outlet configured to be coupled to the second portion of the gas delivery system; an indicator contained within the housing, the indicator configured to provide a first indication to indicate that the gas is being passed from the inlet to the outlet of the housing, the first indication being visible from an exterior of the housing; and a lens coupled to the housing and a pressure sensitive element in fluid communication with the fluid passage, the pressure sensitive element including a colored portion positioned in a first position indicating that the fluid passage contains at least a threshold pressure of the gas introduced through the inlet and a second position indicating the absence of a threshold pressure of the gas in the fluid passage, the first position corresponds to the colored portion being positioned generally at a focus of the lens and the second position corresponds to the colored portion being spaced apart from the focus of the lens.
