Sorry for your lost ts.
My case also similar but during the peak COVID time in Y2021. Before my dad passed away, we were still texting the night before and it looks the situation under control, but somehow the COVID attacked at mid night about the same timing as your dad, then went in to the ICU for rescue but can't get through it.

So it sounds quite common that COVID bring ppl life away during midnight. I think the hospital has done their best, sometimes we need to learn to let it go.

On 20th November 2023, My father was admitted to UNICU HKL due to lack of oxygen, private hospitals cannot check him in because he is a transplant patient and he has records in Government's HKL

On 20th November 2023, My father was admitted to UNICU HKL due to lack of oxygen, private hospitals cannot check him in because he is a transplant patient and he has records in Government's HKL

Due to this we are forced to admit him into HKL, 3 days later after admittance, hospital announce that they have detected a CAT5 COVID confirmed within his system, hence moved him into Isolated UNICU for personal nurse to monitor him.
His oxygen levels are improving slowly at around 90-95, as he's still awake and able to do minimal activities.

On the 3rd of December, his COVID was confirmed by doctor to be no more. But he must remain in UNICU (High Dependency ICU) for further monitoring due to post COVID effect still linger around.

5th December, a doctor written a transfer letter to have him transferred from a High Dependency ICU Ward to a Normal Ward in Institut Perubatan Respirasi (IPR) at 6PM, he arrived there by 6:30PM being placed on a normal ward along with other patients.

He was doing well on same day at 11PM we last checked with him, until later at 3:30AM, we received a call from the doctor there that he has breathing difficulties, asking all of us as a family to get there as soonest.

The time we reach there, almost 4AM on the clock, he's already laying there, lifeless.

We asked the doctor why won't they inform us sooner to allow us exchange a few more words before his passing, doctor then informed us his actual passing time is 3:10AM.

Prayers and Post Mortem is under way..
So the question is :

On the scenario above, can we hire a lawyer to sue either the hospital or the doctor in charge who transferred him for negligence.

As we believe that if he remained in UNICU with a personal nurse monitoring him, he would still be alive and well. We are very disappointed where the doctor who transferred him did not remark that this patient requires High Dependency Ward for close monitoring.

The patient was transferred there but only lasted 7 hours due to breathing difficulty and passed away without being monitored closely.
That being said, Please advise, because us as a family are unable to accept this.

Mine similar case.

Admitted due to covid stay icu and had to use ventilator.
After awhile dr say turn off ventilator coz getting better can talk and move abit.
Suddenly next day dr say condition worsen back on ventilator and got kidney infection until need to do dialysis.
After few days dr sy not good already body cannot tahan and resuccitated few times.
Then gone liao.

Im thinking hospital negligience cause infection kidney failure.
But later read macam covid may cause that too.

Want to ask lawyer but gonna cost money even before start investigate.
