Guatemala: Vital Signs Monitors and Dialysis Machines

Guatemala log #2

During our first day at the hospital we’ve been working on two projects:

The Vital signs monitors. 

The emergency department of Roosevelt hospital has received seven vital signs monitors as donations. They suspect the machines should be working fine, however the cables for measuring oxygen saturation, ECG and oxygen saturation are broken. Unfortunately we cannot test these machines as the power supplies are missing.

Furthermore only managed to collect one set of cables in condition good enough for them to be reapaired and unfortunately buying new ones would cost hundreds of dollars per machine.

For now the strategy will be to get a DC power supply for the machine as quickly as possible (18 V, 2,7A) and then we will try to get just one machine up and running.

The 13-17 dialysis machines

I have seen thirteen machines with my own eyes, some say however that the hospital has 17 Dexter 1550 type dyalisis machines. We started out trouble shooting two of the machines that looked as if they were in a proper condition.

The machines are quite old old but some of them are in a surprisingly good condition. Currently the haemodialysis department is renting machines from an external company, which is expensive, so it is our hope that we can help the hospital by getting their own machines working and thereby save some expenses.

Unfortunately we are currently in doubt whether or not the consumable products are necessary to use the machine are available.

For now however, we are still testing the machine!

Stay tuned for the coming updates for the continuation of these projects and the initiation on the baby-bottle project!

Paediatric Size Blood Pressure Cuffs and Pulse Oximeters

Shortly before we left the KCMC this August, we found out that it was not rare for hospitals to be lacking various equipment in paediatric size. In consequence it would not be possible to measure the oxygen saturation and blood pressure of children. In some cases lack of paediatric size tubes made it impossible to intubate children in need of a ventilator to assist their breathing.

Most of these products could probably be made pretty easily with a bit of creativity. This should give ideas for some design projects for most biomedical/design engineers.

We had a small budget for our various projects from the EWH and we decided to spend what we had left to buy blood pressure cuffs in paediatric size and clip-on pulse oximeters for the paediatric department at KCMC.
