§ 17
How many ml per hour should the feeding pump run to deliver what's ordered?
Answer: When a citizen or patient gets tube feeding, the prescription is often energy per day, e.g. 1,500 kcal, and the pump runs a set number of hours. The calculator converts with the tube feed's energy density (on the packaging, typically 1.0–2.0 kcal/ml) to ml per day and ml per hour and shows how much protein it gives. The prescription comes from doctor or dietitian. The calculator helps you check the pump's setting and the nutrition plan.
Sondemad pr. døgn (ml) = ordineret energi (kcal) ÷ energitæthed (kcal/ml)
Hastighed (ml/time) = ml pr. døgn ÷ timer pumpen kører
Protein (g) = ml pr. døgn × protein pr. 100 ml ÷ 100
Eksempel: 1.500 kcal ÷ 1,0 kcal/ml = 1.500 ml. Over 20 timer er det 75 ml/time og 60 g protein
| Symbol | Meaning | Unit |
|---|---|---|
| ordineret_kcal | Ordered energy per day | kcal |
| energitaethed | Tube feed energy (on packaging) | kcal/ml |
| protein_100ml | Protein per 100 ml (on packaging) | g |
| timer | Hours the pump runs per day | timer |
| = | Pump's speed | ml/time |
| = | Tube feed per day | ml |
| = | Protein per day | g |

En borger eller patient, der får sondemad, har en ordination i kcal pr. døgn. Pumpen skal stilles til ml i timen. Du regner ud, hvor meget sondemad der skal bruges, og hvor meget protein borgeren får.
En borger efter en apopleksi har en ordination på 1500 kcal. Sondemaden har 1,0 kcal/ml og 4 g protein pr. 100 ml. Pumpen kører 20 timer.
It means: Pumpen skal køre 75 ml/time. Borgeren får 1,500 ml og 60 g protein.
En patient har en ordination på 1800 kcal med en sondemad på 1,5 kcal/ml og 7,5 g protein pr. 100 ml. Pumpen kører 16 timer.
It means: Hastigheden er 75 ml/time. Det er 1,200 ml i døgnet med 90 g protein.
En borger spiser lidt om dagen og får 1000 kcal om natten over 10 timer. Sondemaden har 1,5 kcal/ml og 6 g protein pr. 100 ml.
It means: Pumpen skal køre 67 ml/time i 10 timer. Det giver 40 g protein.
Ved 1 kcal/ml er ml det samme som kcal.
Gang ml/time med timerne og med kcal/ml. Så skal du få den ordinerede energi igen.
