Practical Hydration Guidelines for CF Patients

Translating research ch into day-to-day practice requires personalizad recommendations. Because CF patients vary in age, body weight, sweat losses, and kidney functionion, no single fluid reception fits everone. However, general principles appresy:

1. Obliczenia Baseline Needs

Mech corres with CF require between 1; Xi1; FLT: 0 gire3; XI3; XI3; 2.5 L and 4.0 L XI1; XI1; FLT: 1 gire3; XI3; of fluid daily, depensing og climate andd activity level. Children should d start with the standard pediatric formula (30- 40 mL / kg / day) and add extra for exercise and fever. Salt revecement is essential: for every liter of sweat loss, about -2 g of sodidem chlorid apshould bed med, often thalted.

However, drinking too much experately before a meal can dilute gastric acid and reduce enzyme efficacy.

During acute pulmonary recribations, fever increates fluid requirements by an additional 500- 1000 mL / day.
