In 30 seconds

in bed means placing and supporting a person's body in good alignment while they are in bed. It sounds simple, but it is a therapeutic intervention, not just a comfort task. The position of the body affects breathing, circulation, skin integrity, digestion, swallowing, sleep, and dignity. A person who cannot turn themselves depends on the nurse to move the pressure around, keep joints from stiffening, and keep the airway clear.

Positioning sits in the middle of this chapter's skill chain: the mobility assessment (Topic 2) tells you how much the person can move themselves, the transfer (Topic 3) gets them into bed or a chair, and positioning determines what happens to their body once they are there. The next topic covers devices used when movement must be limited — which changes which positioning choices are safe.

Why this matters

People who cannot move themselves are at risk for a cluster of complications that positioning directly prevents:

Pressure injuries — skin and tissue damage over bony areas such as the sacrum, heels, elbows, and back of the head when pressure is unrelieved.
Contractures — shortening and stiffening of muscles and joints from staying in one position.
Respiratory problems — shallow breathing and pooling of secretions can lead to pneumonia in people who stay flat and still.
Aspiration — breathing food, fluid, or saliva into the lungs, more likely when a person lies flat and cannot protect their airway.

Positioning is also a constant, visible part of nursing care — nurses turn and reposition people many times each shift — and it is a standard skill checkoff in nursing programs. Small details, such as where a pillow goes and whether the heels are lifted off the mattress, are exactly what instructors and examiners look for.

Core Concepts

Body alignment and why it matters

is the arrangement of body parts so the spine is neutral and joints are supported in a natural position. In good alignment, weight is distributed across the body rather than concentrated on one point. Pillows and supports maintain the alignment; they should support a joint's natural position, not force it. A pillow that props the head too high flexes the neck, while a pillow under the calves keeps the heels off the mattress and reduces pressure on them.

Standard positions and their purposes

Supine — lying flat on the back. A resting position after many procedures, but it leaves the sacrum, heels, and back of the head vulnerable to pressure, and it raises aspiration risk for people who cannot protect their airway.
— head of the bed elevated. Semi-Fowler's is a moderate elevation (roughly 30–45 degrees); high Fowler's is near-upright (roughly 60–90 degrees). Raising the head eases breathing, helps with eating, and reduces aspiration risk.
— sitting upright and leaning forward, supported by an overbed table and pillows. This position helps a person who is severely short of breath use the accessory muscles of breathing more effectively.
Prone — lying on the abdomen. Used in specific respiratory situations and some procedures, with careful attention to neck alignment and pressure points; not appropriate for everyone.
Lateral (side-lying) — lying on one side with pillows supporting the back and between the legs. Relieves pressure on the sacrum and is commonly used in repositioning schedules.
Sims' position — a semi-prone position on the left side with the upper leg flexed. Often used for comfort, enemas, and some examinations.
Trendelenburg and reverse Trendelenburg — the whole bed is tilted, head down or feet down. Used in specific clinical situations with a provider order, not as casual positioning choices.

Pressure injury prevention and repositioning

Pressure injuries form when pressure on skin and tissue exceeds what the tissue can tolerate, especially over . The core preventive measure is to change position regularly. Facilities commonly schedule repositioning about every two hours for people who cannot move themselves, and many use a risk assessment tool such as the Braden scale to identify who needs the most frequent turning. Schedules, support surfaces, and documentation vary by facility.

Two technique details matter: use the 30-degree lateral position rather than lying fully on the side, so pressure stays off the hip's bony prominence; and offload the heels with a pillow or device so they float free of the mattress — heel injuries are common and hard to heal.

Turning technique: friction, shear, and logrolling

is the rubbing of skin against a surface, such as dragging a person across sheets. It abrades the outer skin.
happens when skin stays in place but deeper tissue slides — for example, when the head of the bed is raised and the person slides down, skin over the sacrum stretches against deeper layers. Shear damages tissue under intact skin.

Both are prevented by lifting rather than dragging: use a draw sheet or lift sheet, and have enough staff so the person is lifted slightly off the mattress. is the technique for a person on spinal precautions: the body is turned as one unit, keeping the head, spine, and hips in a straight line, usually with two or more staff.

Positioning aids and supports

Pillows — under the head (supporting, not forcing), under the calves to offload heels, between the knees in side-lying to keep the hips aligned, and behind the back to hold the position.
Hand rolls and trochanter rolls — keep the hands and hips in neutral positions.
Foot support and boots — keep the feet at a right angle to the legs to prevent foot drop.
Abduction pillows — keep the legs apart after certain hip procedures, per the surgeon's orders.

Devices hold a position; they do not replace the schedule of repositioning.

Positioning for specific conditions

Breathing difficulty: Fowler's or orthopneic positions help the person use the chest and accessory muscles.
After neurological procedures: head-of-bed elevation is often specified by the care team; follow the orders exactly.
After surgery: position per the surgeon's and care team's orders, which may restrict certain positions.
Older adults: skin is thinner and circulation slower, so pressure injuries develop faster; inspect skin at every turn and use supports generously.
Everyone: explain what you are doing, protect privacy, and place the call light and items within reach afterward.

Common Confusions

Do Not Confuse	With	The Difference
Repositioning	Transferring	Repositioning = new position on the same surface; transferring = moving to another surface
Semi-Fowler's	High Fowler's	Semi-Fowler's is a moderate head elevation; high Fowler's is near-upright — for greater breathing support
Supine	Prone	Supine = lying on the back; prone = lying on the abdomen
Friction	Shear	Friction = skin rubbing a surface; shear = layers of tissue sliding in opposite directions
"Positioned comfortably"	"Positioned therapeutically"	Comfort is one goal; alignment, pressure distribution, and airway safety matter too
A pillow under the head	Always helpful	Over-elevation flexes the neck; pillows should support the natural position, not force it

Eli explains

The same idea, in plain words

Explain it like I’m 10

Positioning is arranging someone's body safely in bed so their joints are supported and no one spot presses for too long. It is like rotating tires — you move the pressure around before one spot wears out. Changing position regularly keeps skin healthy and lungs clear.

Worked example

Mr. J., age 74, was admitted after a stroke that left him with left-sided weakness. He cannot turn himself in bed. On rounds, the nurse finds him supine and notes a reddened area over his sacrum — an early warning sign of pressure damage.

The nurse explains what she is about to do, raises the bed to working height, and calls a colleague. Together they use the draw sheet to lift Mr. J. — not drag him — and roll him into a 30-degree lateral position toward his stronger right side. A pillow goes behind his back to hold the position, another between his knees to keep his hips aligned, and his left arm is supported on a pillow so the shoulder stays neutral. His heels are floated on a pillow at the foot of the bed. The nurse inspects the reddened sacrum, documents the finding and the position change, and schedules the next turn — checking whether the repositioning interval should be shortened based on the facility's pressure-injury risk assessment. The same routine — new position, skin check, documentation — is repeated throughout the shift, with Mr. J. kept informed and covered so his privacy is protected.

Key takeaways

Positioning is therapeutic, not just comfort — it prevents pressure injuries, contractures, respiratory problems, and aspiration.
Good alignment: neutral spine, supported joints, weight distributed.
Know your positions: supine, Fowler's (low/semi/high), orthopneic, prone, lateral, Sims', Trendelenburg and reverse Trendelenburg.
Fowler's helps breathing and eating and reduces aspiration risk; orthopneic helps severe breathlessness.
Reposition on a regular schedule (commonly about every two hours per facility protocol) and inspect skin at every turn.
Offload heels and use the 30-degree lateral position to protect bony prominences.
Lift, don't drag — friction and shear damage skin and deeper tissue.
Logroll for spinal precautions: turn the body as one unit, spine in a straight line.
Document position changes, skin findings, and any devices used.

6 review questions from the chapter. Try each one, then open the answer.

Why is repositioning important for a person who cannot move themselves?
Show answer
It relieves pressure over bony prominences (preventing pressure injuries), keeps joints from stiffening (preventing contractures), and helps keep the lungs clear by changing the pattern of breathing.
Which position best supports a person who is short of breath, and how is it set up?
Show answer
Fowler's position (head elevated) for general breathing difficulty, or the orthopneic position — sitting upright and leaning forward on a supported table — for severe breathlessness.
What is the difference between friction and shear?
Show answer
Friction is skin rubbing against a surface; shear is skin and deeper tissue sliding in opposite directions. Both damage tissue and are prevented by lifting rather than dragging.
Why is the 30-degree lateral position preferred over lying fully on the side?
Show answer
Lying fully on the side puts pressure on the hip's bony prominence (the greater trochanter); a 30-degree angle distributes pressure more safely.
What must the nurse do every time a person is repositioned?
Show answer
Inspect the skin (especially bony prominences) for redness or breakdown, support the new position, confirm the person is comfortable and safe, and document the turn and any findings.
What does logrolling mean, and when is it used?
Show answer
Turning the person as one unit, keeping the head, spine, and hips aligned with no twisting — used when a person is on spinal precautions.
