I'm an ICU nurse in New York City. I start my day at 5:30 am with a prayer, a cup of coffee, and rounds with my trauma patients.

• Nancy Hagans is an intensive care unit nurse in NYC and union president.
• She told Business Insider about how health tech has changed during her 39-year career.
• Each shift is intense, but Hagans said nursing is the most rewarding job she's ever done.

This as-told-to essay is based on a conversation with Nancy Hagans, a nurse in the intensive care unit at New York City's Maimonides Medical Center and president of the New York State Nurses Association. The union ended a 41-day strike in February, securing raises and layoff protections for staff. This conversation has been edited for length and clarity.

I wake up 5:30 a.m. each morning, say my daily prayer, have a cup of coffee, and arrive at work at least half an hour early.

I've been a registered nurse for the past 39 years, and most of my work is in the surgical intensive care unit. I start my shift by greeting the night nurses and checking on my patients, but there's rarely a routine day at the ICU — it could be quiet one minute and the next minute, everything is happening. My hospital is a trauma center, so I could walk into an emergency before I even put my coat down.

I decided to become a nurse because I'm from Haiti, and my Haitian patients were discriminated against. Going to the hospital was very hard, and I wanted to be in a situation where I could make a difference for immigrant communities.

The profession is extremely rewarding. The nurse is the first person patients see when they walk in, and the last person they see when they leave. In stressful situations, the patient depends on their nurse. I may have to walk away, wipe my eyes, and take a deep breath, but then I go back to their room and think: What is it that I could do to make this person better? How can I alleviate their anxiety?

If you're nervous, odds are the patient is nervous, and the family is nervous. I have to be the advocate for my patients. It's my job to make sure they are receiving the proper medications and are seen quickly by the doctors. Every patient is a VIP, and I treat them with the highest quality of care — regardless of their religion, background, and immigration status.

Technology has changed throughout my career, and I welcome the help. When I first became a nurse, I had to do everything myself. I calculated medication doses and hand-wrote patient reports. Computers are much faster at organizing these treatment notes, doing math, and protecting sensitive information. It's not a replacement for the human touch, but it helps us document our care more effectively and spend more time with patients.

When it comes to care, we are not going to cut corners. We're not going to stop fighting for our patients, our colleagues, our pay, and safe staffing ratios at our workplaces — because more nurses means better care. I need people to know that nurses are the front line, they're the backbone of every hospital. The medical field can't operate without us. We keep our patients alive.

I would encourage students to think about nursing as a profession. About a year-and-a-half ago, I ran into a former patient in a supermarket. Standing in the aisle, this former patient told me, "You don't remember me, but I could never forget you."

It's the most rewarding job I've ever done.
