摘要
For non-invasively measuring and assessing patient haemodynamic performance, two sensor systems are used as the raw data inputs. The first sensor system is an ear densitometer 12 which photoelectrically records the instantaneous amount of blood within the blood vessels of the ear. The second sensor system is a standard electrocardiogram on lead 19. The densitometer and electrocardiogram signals are conditioned and processed to permit measurement of specific performance parameters. These are pre-ejection phase, PEP; left ventricular ejection time, LVET; and PEP/LVET. The measured quantities are displayed on a cathode ray tube 28 in a variety of formats upon operator request and recorded by a printer 30. IMAGE
