The goal of this observational study is to investigate methodological if ultrasound is comparable to chest X-ray in verification of intensive care patients enteral feeding tube positioning.

The main question to answer is: Is ultrasound a comparable method to chest X-ray in verification of intensive care patients enteral feeding tube positioning.

In Norway, around 4000 patients are yearly in need of ventilator, and many of them will need enteral nutrition through a feeding tube. 40 % of all intensive care patients have signs of malnutrition. If ultrasound is a comparable method to chest X-ray in verification of intensive care patients enteral feeding tube positioning, then enteral nutrition in many cases can be started several hours earlier than using chest X-ray verification. The ultrasound examination will be performed in a research based in a 4-step approach. In this project 20-30 intensive care patients prescribed by a medical physician to have an enteral feeding tube will be included in the project due to written informed consent by 1) Awake intensive care patient or by 2) Patients informal caregiver if the patient is not competent to consent.

Inclusion Criteria:
