Solution for pulmonary disease necessitating at home oxygen therapy.
Some pulmonary diseases are affecting the lungs in a way where the need for oxygen varies depending on the activities of the patient. In example, a patient sitting down may need 1L per minute of continuous oxygen; when walking that oxygen need may increase to 2L per minute, when walking up a flight of stairs that need may increase to 3L per minutes.
One problematic:
Medical point of view:
The oxygen consumption of the patient must stay to a bottom limit. If the patient uses more oxygen than he/she requires, he/she will increase the chance to retain CO2 and suffers on long-term of CO2 intoxication.
When a patient increase his activities but has insufficient oxygen, the patient will suffer from hypoxia. The heart will try to compensate and that will make the effort much more demanding to a point where the effort needed can sometimes not be done. Hypoxia can set in very quickly.
So, bottom line, the patient sitting down with 1L of oxygen must change the flow of oxygen to 2 L when he starts to walk, then when sitting down again, the flow must be adjusted back to 1L.
Physical point of view:
In home oxygen therapy an oxygen concentrator is often use to deliver the extra supply of oxygen through an oxygen tube. The concentrator is a loud, heat-producing device. It is usually place as far as possible to where the patient and its family live.
The problem is that the patient needs a second person to adjust the oxygen flow depending on his need.
The solution:
Is to simply rig the oxygen concentrator flowmeter with a remote control motor.
The patient has a remote controlled transmitter, a flowmeter and a oximeter.
The patient can adjust the flow of oxygen from a distance before and after an activity.
The patient can validate the flow he/she receives with his/her flowmeter. Also the patient can monitor his/her oxygen blood saturation using his/her oximeter.
The results:
Having the oxygen adjusted to the right level for the activities of a patient results in a greater comfort (not being out of breath all the time), better activities, less fatigue, better health for the organs in general.
