B5 · Poor blood flow to hands or feet
Actual Breathing and circulation
Definition
The limbs receive too little blood and may look pale or blue, feel cold, or have weak pulses.- Narrowed arteries
- diabetes
- smoking
- blood clot
- tight dressings
- Cold, pale, or blue hands or feet
- weak pulses
- slow wound healing
- leg pain when walking
📋 Scenario
A diabetic patient has a cold, pale left foot with a weak pulse and a slow-healing toe sore.
Subjective (S): "My left foot always feels cold and my toe sore will not heal."
Objective (O): Left foot cold and pale; weak foot pulse; capillary refill 5 seconds; toe sore 1 cm and not healing for 3 weeks; blood sugar 12 mmol/L.
Assessment tools for this scenario: CP-BREATH Breathing & Circulation Check CP-SKIN Skin & Wound Score CP-FLUID Fluid Balance & Nutrition Score
Validated scales to consider: NEWS2, SpO₂, ECG, Braden Scale, TIME wound chart, MUST, fluid chart, glucose
**CarePath diagnosis:** Poor blood flow to hands or feet related to narrowed arteries, as evidenced by cold, pale, or blue hands or feet and weak pulses.
**Interventions and rationale**
| Intervention | Rationale |
|---|---|
| Check pulses, color, and warmth. | Checking pulses, color and warmth shows how well blood reaches the foot and picks up worsening supply early. |
| Keep limbs warm but avoid heat pads. | Gentle warmth helps keep vessels open, but heat pads can burn skin that has poor blood flow and reduced feeling, and cannot carry the heat away. |
| Avoid tight clothing. | Tight clothing can squeeze vessels and further reduce blood flow that is already poor. |
| Encourage no smoking. | Smoking narrows blood vessels and lowers the oxygen carried by blood, so stopping improves flow and wound healing. |
| Report sudden pain or color change. | Sudden pain or color change may mean a clot has blocked the artery, which threatens the limb and needs urgent treatment. |
**Expected outcomes**
- During the stay: foot stays warm and pink with a felt pulse.
- Within 2 weeks: wound smaller.
- Patient states foot care steps and accepts support to stop smoking.
**Linking the data to the diagnosis**
The patient is diabetic and has a cold, pale left foot with a weak pulse, capillary refill of 5 seconds and a 1 cm toe sore that has not healed for 3 weeks. She says the foot always feels cold. Blood sugar is 12 mmol/L. This is an actual problem because the poor circulation is already visible in color, temperature and slow healing. A skin or wound statement would miss the underlying cause, which is too little blood reaching the foot. The plan aims for a warm, pink foot with a felt pulse during the stay, a smaller wound within 2 weeks, and the patient stating foot care steps and accepting help to stop smoking.

Interventions and rationale
Listed in priority order.
