77th day of attachment

I got the chance to be some repair for simple devices such as the mattress alternating pressure system and ecg recorder. For the ECG recorder, the nurses keep saying that the printed waveforms have a lot of noises that makes some informations in the waveform lost. I went to the particular ward to check the device by using patient stimulator by selecting normal ECG. The fault lies with the printer as the paper is not placed properly and may caused by any slight movement of the patient's body that create this problem. For the mattress alternating pressure system, the internal wires are being exposed so i placed the insulation wire around it.
