What Happens in the ICU — A Guide for Families Who Have a Loved One Admitted

If your family member has just been admitted to ICU, you are reading this in shock. The machines look frightening. The medical language is dense. This guide explains everything you'll see — in plain language.

What All the Machines Do

Multi-parameter monitor (the screen above the bed)
Shows heart rate (top), oxygen saturation (SpO2), blood pressure, breathing rate, and temperature. Numbers change — that is normal.
Ventilator (the breathing machine)
Pushes air into the lungs through a tube in the mouth (intubation) or a mask (NIV). Most patients on ventilators come off them.
Infusion pumps (the small boxes hanging from poles)
Deliver precise amounts of medication, fluids, and feeding through veins or feeding tubes. Many lines are normal — not an indicator of severity by themselves.
Urinary catheter
A tube to drain the bladder. Allows precise measurement of urine output — an important sign of how the kidneys and circulation are doing.
Central line (in the neck or chest)
Larger IV access for medications that can't go through small veins (e.g., vasopressors, strong antibiotics). Removed when no longer needed.
Arterial line (in the wrist)
Continuous blood pressure measurement and easy blood draws. Standard for unstable patients.

Daily Routine in ICU

Morning rounds (typically 8–10 AM). The ICU team — intensivist, specialist consultant, nursing in-charge, sometimes physiotherapist — reviews each patient. Plans for the day are made. Family is rarely present at this time but updates are shared afterwards.

Through the day. Hourly nursing observations. Medications at scheduled times. Investigations (blood tests, X-rays, scans) as needed. Bedside physiotherapy if appropriate. Sedation and pain management adjusted.

Evening rounds (typically 5–7 PM). Day's progress reviewed. Overnight plan made. Family update typically given around this time.

Overnight. Continuous monitoring by ICU nursing team. Intensivist on call. Calls to family only for significant changes.

What "Sedation" Means

Many ICU patients are sedated — receiving medications that keep them drowsy or asleep. Reasons:

  • Comfort on a ventilator — the breathing tube is irritating; sedation keeps the patient calm and synchronised with the ventilator.
  • Reduce metabolic demand — in severe illness, reducing the body's work helps recovery.
  • Reduce distress — for patients in extreme respiratory distress before intubation.

Modern practice favours light sedation — patients are arousable, can follow simple commands, but are kept comfortable. Heavy sedation prolongs ICU stays and increases delirium.

Daily "sedation holds" — turning off sedation each morning to assess neurological state — are now standard.

What "Critical But Stable" Means

This phrase is often confusing. In ICU language:

  • Critical: The patient is seriously unwell with vital functions requiring active support (e.g., on a ventilator, on vasopressors).
  • Stable: Not deteriorating in the last 12–24 hours. Trends in oxygen, blood pressure, organ function are flat or slightly improving.

"Critical but stable" means the patient is still very ill but holding their ground — not improving rapidly, but not getting worse either. It is a hopeful sign in the early phase of severe illness.

Other common phrases:

  • "Critical and deteriorating" — getting worse despite maximal support.
  • "Stable, weaning ventilator" — improving, planning to come off the breathing machine.
  • "Stable for step-down" — well enough to leave ICU for the ward.

Visiting and Communication

Visiting policy at Gini ICU: 2 family members at scheduled times (typically 10–11 AM and 5–6 PM). PPE provided. Restricted hours protect patients from infection.

Family communication: A designated nurse provides twice-daily updates. The ICU consultant or specialist meets family at least once daily, more often for significant changes. Emergency calls to family for any major change.

What you can ask:

  • How is my family member today compared to yesterday?
  • What are the main problems being treated?
  • What are the plans for today?
  • What complications are we watching for?
  • What is the realistic outlook for the next 48 hours?
  • When might they leave ICU?

Don't feel embarrassed to ask "in plain language." Doctors should explain in simple terms. If anything is unclear, ask again.

After ICU — What Happens Next

Most patients leaving ICU go to the ward, not directly home. The step-down ward provides closer monitoring than a regular ward but less intensive than ICU.

Post-ICU recovery: Many patients experience post-ICU weakness (loss of muscle from prolonged bed rest), confusion (post-ICU delirium), and emotional after-effects (anxiety, low mood). These are common and treatable. Physiotherapy starts on the ward and continues at home.

Discharge from hospital: Typical timeline 1–3 weeks after ICU discharge depending on the underlying illness and recovery pace. Outpatient follow-up arranged before discharge.

Frequently Asked Questions

Yes — at Gini, 2 family members at scheduled visiting times (typically 10–11 AM and 5–6 PM). PPE provided. Restricted hours protect patients from infection. For unstable patients or end-of-life situations, expanded visiting can be arranged.
Twice-daily updates from a designated nurse. Daily review with the ICU doctor or specialist consultant. Look for trends: reducing oxygen requirements, lower vasopressor doses, improving urine output, lower lactate, normalising kidney and liver function. Day-to-day fluctuations are normal — trends matter more.
A ventilator is a temporary breathing support — not a sign of imminent death. Most ventilated patients come off the ventilator. The duration depends on the underlying problem. Average ventilation is 5–14 days for typical respiratory failure.
Highly variable. Post-surgical observation: 12–24 hours. DKA: 2–3 days. Pneumonia in ICU: 7–10 days. Severe sepsis: 7–14 days. Mechanical ventilation: 10–28 days. The honest answer changes daily as the team observes how the patient is responding to treatment.
Most patients move from ICU to a ward (step-down), not directly home. Ward stay typically 1–3 weeks for ongoing recovery, physiotherapy, and stabilisation. Discharge home happens once eating, walking (with aids if needed), and medications are stable. Outpatient follow-up arranged before discharge.
A designated nurse provides twice-daily updates. The ICU consultant meets family at least once daily, usually after evening rounds (5–7 PM). For urgent queries, ask the nurse to call the on-duty doctor. Don't hesitate to ask for "plain language" explanations — it's your right to understand.
