Strengths and limitations
The limitation of this study is that it was carried out in a tertiary level hospital where there is the availability of human resources and materials to combat severe haemorrhage for this reason very few patients may present complications such as coagulopathy and needs for intensive care unit admission, for this reason, we cannot tell the exact risk those complications using our capillary scheme. On another side, one of its advantages is that the materials needed to obtain these results are portable devices that can be easily obtained in the market, and thus low resourced facilities can obtain them for their patient monitoring.
