Hardware Requirements

To practise this tutorial, you will need Maestros STEMI Kit.

Show image The Hospital Model of this kit, consists of
  • An Android Tab in a metal casing
  • Maestros Device with NIBP, ECG and SPO2 monitor, all in a single device
  • Wi-Fi Printer
  • Trolley
  • Power Strip
Show image The Ambulance Model of this kit, consists of
  • An Android Tab in a metal casing
  • Along with NIBP, ECG and SPO2 monitor, all in a single device
  • And a Power Strip

The Ambulance Model does not have a Wi Fi Printer and is not mounted on a trolley.

Show image In the Ambulance Model the metal casing of the Tab is mounted with a clamp.
Show image The HP Tablet is the data entry device. It has-
  • A power button on the the top of the Tab
  • 2 micro USB ports and an HDMI port at the bottom
Show image Out of the 2 USB ports, the port which is right-most, is used for charging the Tab.
Show image The Android Tab can be charged either with a
  • standard Micro USB charger
  • or with the USB cable hanging out from the Maestros Device.
Continue same pic When this cable is used, the Tab derives power from the Maestros Device to charge itself.

This facility is provided so that the Tab need not be charged by plugging it to a power point.

Rather the device can be carried around while the Tab is being charged.

Show image The Tab is attached to the Maestros Device with a metal casing.

The Tab and the Maestros Device are separate devices.

But they act as a single unit because of the metal casing that surrounds them.

Slide The Maestros Device has 5 Ports

1 - Charging port

2 - ECG port

3 - BP port

4 - SpO2 port

5- Temp

Show image It has a Power button along with the charging port on the left side.
Show image And the ECG, BP & SpO2 port on the right side.

The Maestros Device also two greenish yellow indicator LEDs on its left side.

  • one that lights up once the Maestros Device is switched on
  • the other that lights up when the device is in charging mode

Show image

Now let’s look at the Non Invasive Blood Pressure unit.

The B.P cuff has two parts - the B.P cuff cable and the extension cable.

Show image First connect the B.P cuff cable to the extension cable.
Show image Then connect the other end of the extension cable to the B.P port.

As mentioned earlier, this is located at the left bottom side of the Maestros Device.

Now we are all set to take the B.P.

Next we will look at the SpO2 unit.

The SpO2 cable has two parts -

  • the extension cable
  • and the SpO2 probe
Show image Connect the extension cable with the SpO2 probe, as shown.
Show image Snap the transparent cover into place to secure the connecting cables.
Show image The other end of the extension cable has to be connected to the Maestros Device.
Show image Connect it to the port at the top left side of the Maestros Device.
Show image Now, we are all set measure the SpO2.

Next, let us look at the ECG unit.

Connect the ECG cable…..

Show image the ECG port at the top left side of the Maestros Device as shown here.
Show image Secure the connection by tightening the screws on either side of the connector head.
Now we are all set to take an ECG.
Summary slide Let us summarize.
