Our hypothesis is that, for the patients who have high hemoglobin concentration, the average pulse amplitudes should be different from their normal condition. To verify our assumption, we diluted the blood of normal subjects by letting them drink the water. According to our experiment, 80% of the subjects had higher pulse amplitude.engMahidol UniversityHemoglobinpulsediagnosticblood oxygen levelSpringerLink e-BooksProceeding BookSpringer-Verlag Berlin Heidelberg10.1007/978-3-642-29305-4_375
