using arterial waveform to estimate stroke volume
- related: Cardiology, ICU intensive care unit
- tags: #literature #cardiology #icu
- assumptions for this to be used
- flow of blood into artery must equal outflow of blood
- contractility of vessel relates to amount of blood flows through the vessel
- systole: inflow of blood expands artery and is greater than outflow
- diastole: vessel contracts. Outflow of blood is greater
- Area under curve: represents systole and diastole. Sum can be used to estimate stroke volume1
