In my opinion, the events that happen in the hospital in this chapter show how empty the society is in terms of emotions and human feeling.
In this chapter, John's mother is dying. In our society, this would be a hugely emotional event. In this society, however, there is no significance. Instead, you have all of these faceless children swarming around being taught that what is going on has no meaning.
I think that Huxley is using this chapter to comment on how horrible this society is. It turns people into machines and robs them of their human emotions.
