Language
Paul Kafka uses very descriptive language when expressing what Dan sees.
                    Jennifer Sandler is the magician here tonight. Renee Gilbert plays the role of her beautiful, silent assistant. Soon the baby will spring
                     from the trick box of Renee's belly.

He uses specific verbs as if to make the reader feel the sound that each action makes when it is performed.
                    ...come thudding through the internal monitor with the steady rhythm of a galloping horse (heartbeats)

Uses specific adjectives.
            shining brilliant lights,

There are plenty of medical terms when describing the procedures done.The explanation of the procedures helps the reader understand that each drug administrated provokes.
          Sandler uncovers the pink dome of the uterus, which pushes up against the eye-shaped window in the transversus abdominis.
           ...then hydrated her and put her on terbutaline to stop her or at least slow her down. He also gave her a shot of betamethasone to
           accelerate fetal lung maturity.

Metaphors:

Another resourse Paul Kafka uses is metaphoric language, which most of the times tend to be funny phrases that make the reading more interesting and enjoyable.
                 ...That's what finally reserved Renee this prime, dinner-hour table in OR
                  We're the two youngest in the room, not counting whoever's inside...(inside the mother, Renee)
                  [about Renee] She's the color the nurses here call cream (euphemism)
                 I'll conjure you right up into the air,the way Sandler abracadabraed Jordan out of Renee's belly.

The use of comparison is also visible at some point.
My hands walk up and down this keyboard like Jennifer Sandler's own

Feelings:
When Dan is presencing the birth of the baby, he mentions how he feels a little sorry about Renee,since this Delivery was not going to be normal. Renee is excited about it but since everything is complicated, Dan decides to distract her. Dan says " but I'm new here and afraid to speak unless spoken to". He' is being careful.
Once Dan goes out of the Delivery he encounters one of his bosses. The boss ignores what he says and that makes him feel ignored. "He asked me who I was and if I knew anything about outboard motors, Good to have you aboard, he said, and then told me all about his motor anyway."

When Dan decides to write a letter to Bou, since he had been thinking about her, he finds a PC he can use. He tries to tell Bou as well as the reader the inhumane conditions he is in at this hospital. "Kate says this PC, the steel doors between wards, and the cloth partitions inside the giant rooms were supposed to drag Charity into the modern era.".

He also wants to let her know the details of the things he does. He knew how his recepiet was going to react when she read the words that he was destining to her: The words just poured out. I started describing the C-section. I knew you'd want to know everything. I had to type as fast as I could, just to keep up with your questions.

Besides feeling sad about the conditions he is working on, Dan also feels down: "Who knows where I am. All I can say with confidence is that I'm not in New Orleans, I'm not in October 1992...Over the next ten weeks I could update my records and try to figure out what's going wrong with me. I think it's a memory problem. I've got to free up some working memory. I'm always going to function in the fog that has surrounded me since last spring. "

He appeals to the memory of Bou by telling her "...The records for one year in particular--a year you know wverything and nothing about are such a mess that my only chance of sorting through them is to toss everything out and start from scratch."

Dan mentions the fact that he need her and needs to explain what happened in that Paris that they knew and cannot forger. He wants to describe everything around him because he wants her to know what it is like to be where he is at the moment."There's nothing I won't tell you, except how much I'm still thinking about you, which you know. I'll write about my New Orleans and especially about that Paris we knew, which stubbornly refuses to stay in the past. I'll conjure you right up into the air, Bou, the way Sandler abracadabraed Jordan out of Renee's belly. Then, when you're floating in front of me, I won't reach out. I'll just look, while everything else disappears."

When he realizes he is wanting to tell Bou all about his day he writes: "That makes this a love letter, doesn't it? I'm writing you a love letter." This moment inspires tenderness and careness from Dan to Bou
