Flow Amount of fluid moving per unit time is flow. It may be laminar or turbulent. Laminar flow :WhereQ = Flow in Litres/secondn = ViscosityP = Pressurer = Radius of the tube in metersl = Length of the tubePrimary FRCA physics
16 pulse oximetrya) T - At wavelength of 660 absorbance ofoxyhaemoglobin is less than deoxyhaemoglobin,b) F - In infrared light (940 nm), the absorbance ofoxy-Hb is greater than that of deoxy-Hb.c) T - Isobestic point at 805 nm.d) F - The diodes are switched on and off at highfrequency several hundred times a second.e ) T - Pulse oximeter must be used duringanaesthesia.Primary FRCA physics
