The Turner family from New Zealand purchased the equipment to show their appreciation to doctors at the hospital who cared for their daughter.
Their infant child was involved in a medical emergency a few months ago while they were visiting Rarotonga, and the family was so grateful for the service they received at the hospital, they decided to donate the oximeter.
Chris McCammon of New Zealand Medical & Diagnostics delivered the equipment to the hospital last week and the company also took care of courier costs.
The portable meter is compact and lightweight. It indicates levels of oxygen in patients that could be life-threatening. As well as a cable connection it has rechargeable batteries.
The director of clinical services, Dr Yin May, had been delighted to accept the gift on behalf of the hospital, McCammon said.
