q1.can anybody suggest a good neonatal fingertip pulseoximeter or any lowcost pulseoximter working well for neonates for outpatient and postnatal ward use ?

q2.what is the difficulty in making a fingertip pulseox for neonates when pediatric models are available ?any body know technical details,mechanism of finger pulseox/ links ?

1. I remember that BMJ had a Christmas Appeal (for donations) about this device: http://www.lifebox.org/what-we-do/pulse-oximetry/

2. I pass on this question... I read here http://www.lifebox.org/purchase-oximeter/ that the probe is from 3 months... but I suggest you email and ask specifically about neonatal use
