This is a piece of equipment that you may come across in a maternity hospital.
It is used to look after newborn babies in the first few minutes after they have been born.
It should contain all the things that a doctor or midwife will need to attend to the newly born baby, both for normal procedures and for emergencies.
It will have on it oxygen, suction and sometimes an overhead heater.
There will be bottles of oxygen at the rear and maybe a pipeline that can be plugged into a wall supply.

The sucker will most often work off the oxygen supply by VENTURI action.
Venturi is where a strong jet of air or in this case oxygen is passed over a tube like a `T’ piece (that is straight across the top of the arm of the `T’ piece) and in doing this air is dragged up the arm of the `T’ piece and pulled in to the stream of passing air, this creates a partial vacuum in the arm, this is how the vacuum is derived.
It is obviously a very wasteful use of oxygen, so if you are able to use an electric suction, or a foot operated one so much the better.
The safety valves on these will be set much lower than on ventilators, about 40 cm H2O, some doctors say that it should only be 30cm H2O.
There may even be water manometer, this is a clever but simple type of safety valve, it is clever in that it has no parts to wear out, it consists of a tube about a foot deep and about three inches diameter, into it there will be a tube that goes nearly to the bottom, this tube is connected to the tube that goes to the patient by a `T’ connector, behind this tube is a scale graduated in centimetres with the zero mark at the top, the large tube is filled up with water to the zero mark.
Now when pressure is applied to the small inner tube the gas can only get out by pushing the water out of the tube, the pressure that it has to overcome is obviously the same as the depth of water, thus by making the water deeper so you can increase the blow off pressure.
Once the air has blown out of the tube it vents to the atmosphere.
They are very easy to make, and the beauty is that you can make them to any size and therefore pressure that you need, obviously the pressure units that they are calibrated in will be either Centimetres of water or inches of Water.
One thing that you must be careful of with water manometers is that you change the water often, otherwise it can get contaminated.

As far as maintenance goes you can expect the same types of faults as on an anaesthetic machine, gas leaks, rotameters stuck, suction not working, these can be dealt with in the same way as you will have been doing on your anaesthetic machines.
The overhead heaters should not be closer to the baby than 24 inches.
Repairs to these will be of an electrical nature.
Make sure that they have been electrically safety checked once a year, if you do not have the proper electrical safety check tester a good visual inspection as described in the article on electrical safety can be done.
