# Patient positions: Fowler, supine, lateral, prone and others

- Safe practice

Every position in bed has a reason: breathing better, eating without aspiration, relieving pressure or making a procedure easier.

Updated Nov 5, 2026

## Key points

- Semi-Fowler: head of bed at 30–45°. Fowler: 45–90°. High Fowler: 90°.
- Fowler and semi-Fowler help lung expansion and prevent aspiration when eating or on tube feeding; semi-Fowler is better tolerated for long periods.
- Lateral: relieves the sacrum and coccyx; in pregnancy it avoids compressing the inferior vena cava.
- Prone: may improve oxygenation in some severe respiratory disorders.
- Trendelenburg (head lower than the feet): its benefit in hypotension is doubtful and it carries risks; today it is used little and only when ordered.
- Bed-bound patient: reposition at least every 2 hours and check the skin at each change.

## What it is

Positioning the patient well is a nursing intervention with a purpose: it improves breathing, prevents aspiration, relieves pressure on the skin, protects the joints and makes examinations and procedures easier. The goal is functional alignment: spine straight, head neutral and limbs in a functional position. A bed-bound patient who cannot move on their own is repositioned at least every two hours, the skin is checked at each change, and pillows, wedges and special surfaces are used to spread the pressure.

## What it requires

- Knowing the reason for each position and its contraindications (hip surgery, spine, raised intracranial pressure).
- Two people or slide devices to move dependent patients.
- Pillows, wedges and heel protectors to align and spread pressure.
- Documentation of each position change and of the skin.

## How it is applied (and why)

- Check the order, the reason and the restrictions (hip, spine, drains) — every position has contraindications.
- Explain, give privacy and get help or a slide device if the patient is dependent — it prevents injuries and falls.
- Lock the bed, raise it to working height and lower the head of the bed if turning — protects your back and eases the turn.
- Move the patient as one unit, sliding and not dragging — prevents friction and shear on the skin.
- Align: spine straight, head neutral, limbs in a functional position — avoids contractures and nerve injury.
- Place pillows or wedges and float the heels — spreads the pressure over bony prominences.
- Check that tubes, drains and oxygen tubing are not under the body or pressing on the skin — they also cause injuries.
- Check the skin, leave the call bell in reach, the bed low and locked, and record position and time — keeps the turning plan going.

## Positions and why they are used

| Position | What it looks like | What it is for |
| --- | --- | --- |
| Supine (dorsal recumbent) | Flat on the back, pillow under the head | Examination, rest; watch the heels and sacrum |
| Semi-Fowler | Supine with the head of bed at 30–45° | Better breathing, aspiration prevention; tolerated for hours |
| Fowler / High Fowler | Head of bed at 45–90° (high: 90°), hips slightly flexed | Breathlessness, eating, tube feeding; keeps the patient from sliding down |
| Lateral (side-lying) | On the side, top leg flexed, pillow between the knees | Relieves sacrum and coccyx; pregnancy (no vena cava compression) |
| Sims (semi-prone) | Between lateral and prone, legs flexed, arm free | Enemas and some examinations; drainage of oral secretions |
| Prone | Face down, head turned, pillow under the lower legs | May improve oxygenation in certain severe disorders |
| Trendelenburg | Bed tilted, head lower than the feet | Limited use: doubtful benefit in hypotension; only when ordered |

## In nursing practice

- After hip surgery, the patient does not lie on the operated side and an abductor pillow is placed between the legs.
- The feet tend to fall into plantar flexion in bed: on prolonged bed rest, devices that hold the foot at 90° are used.
- In breathlessness, the tripod position (sitting and leaning forward on a table) helps breathing.
- A turning clock in the room helps the whole team follow the repositioning schedule.

## Common mistakes

- Leaving the patient in Fowler without slightly flexing the hips: they slide towards the foot of the bed and shear occurs.
- Leaving an arm trapped under the body when turning the patient: it can cause nerve injury.
- Using Trendelenburg out of habit for any hypotension, without a medical order.
- Repositioning without checking the skin or recording the change.

## Test yourself

Think of the answer, then tap the question to see it.

## To what angle is the head of the bed raised in semi-Fowler?

Between 30 and 45°. It helps lung expansion, helps prevent aspiration and is better tolerated for long periods than high Fowler.

## Why is a pregnant woman in the third trimester laid on her side?

The lateral position keeps the uterus from compressing the inferior vena cava, which improves venous return.

## How often, at the least, is a bed-bound patient who cannot move on their own repositioned?

At least every 2 hours, alternating sides and back, and checking the skin at each change.

## Why is the Trendelenburg position used little today for hypotension?

Its benefit is not proven, and it can make breathing harder, raise intracranial and intraocular pressure and favour regurgitation.
