Abstract : Fabrication at DIPAS of a low resistance respiratory valve from totally indigenous materials costing Rs.500/- is reported here. Experimental data reveal that the dead space in the valve is 230 ml and the pressure drop across the valve (i.e. the resistance) at a flow rate of 240 litres per minute is 1 cm of water.
