Neocare

The Medisys NEOCARE is a micro-controller based ventilator designed for patients ranging neonates to paediatrics. While ventilating such patients, safety features are of prime consideration. The ventilator incorporates the features of both pressure and volume limiting to reduce the possibility of barotraumas and volume trauma that may occur even at a low pressure. The inspiratory phase is terminated as the pressure of the tidal volume tends to exceed the set limit. The ventilator adopts the widely accepted technique of continuous flow with time cycling for ventilating new-born and paediatric patients. It provides for modes like CMV, ASSIST, SIMV and SPONTANEOUS with CPAP facility. Apnea back up ventilation is available in SIMV and Spontaneous modes. All set and monitored data are displayed on a large 12.1 inch LCD screen. The monitored patient data includes expired tidal volume, minute volume and delivered FiO2 . It also provides for simultaneous display of pressure and Flow Curve. The oxygen blender is servo controlled with closed loop feed- back system. FiO2 can be set from 21% to 100%. For emergency 100% oxygen, set FiO2 can be bypassed at any instant by pressing 100% O2 button. It is reset by pressing the button again. The selection of gas flow remains unaffected even if there is a failure of either air or oxygen, as the unit automatically switches to the available gas supply. A fall in pressure due to patient effort is recognized for pressure triggering. However, the presence of continuous flow trends to neutralize this pressure drop. So more effort is needed to trigger the ventilator. This may be exhausted and result in increased WOB. The Neocare adopts triggering by flow to make it more effective. The flow sensor detects a flow caused by the patient’s effort to trigger ventilator. The flow is detected at the proximal of the patient, thereby avoiding any false triggering due to leakage in the two limbs of the breathing circuit. Moreover, it makes the triggering PEEP compensated.
