A chronically ill patient may not have received enough oxygen on the night he died, an inquest has heard. The Coroner's Court heard that unemployed Yip Ming-cheong, 33, died on May 25, 2006, at Alice Ho Miu Ling Nethersole Hospital. The court heard Yip had suffered from multiple illnesses including asthma and was frequently in and out of hospital. He had also been wheelchair-bound since 2003. Yip was admitted to hospital five days before his death suffering from a spasm. His elder sister, Yip Pik-yi, testified that when she left the hospital about 7pm on May 25, her brother could talk and made no complaint of any discomfort. But at 9.25pm the hospital called to say he was in critical condition, and by 10.20pm he was dead. Pathologist Cheng Hok-fat testified that Yip had died from asthma and bronchopneumonia. Counsel Tim Kwok Tin-sui, representing Yip's family, repeatedly questioned the doctors and nurses caring for him on the night he died as to whether he was given adequate oxygen. Lai King-son, an on-call doctor there at the time, testified that Yip was suffering from shortness of breath the night before he died, which may have been caused by the bronchopneumonia. He also admitted he had not looked at Yip's X-rays. Yip had only 70 to 80 per cent oxygen in his blood, compared with a normal person's 98 per cent. Nursing officer Ng Suk-yee also told the inquest he was given only a ventilator and not an oxygen mask. There was no order to increase his oxygen supply. Health assistant Tse Lai-ha said Yip had had only one doctor's visit from 2pm to 9pm on the day he died. The hearing continues.
