Brief Summary:
The main purpose of the study is to evaluate whether the routine use of ultrasound guided arterial puncture can increase the proportion of patients who only needs one puncture attempt in order to successfully extract enough blood to make an arterial blood gas analysis, when ultrasound guided arterial puncture is compared to conventional arterial puncture technique.

Arm Intervention/treatment
Experimental: Ultrasound guided arterial puncture
Patients randomised to the this arm has arterial puncture performed using simultaneously ultrasound in order to guide the passage of the syringe from the patient's skin to the artery
Procedure: Ultrasound guided arterial puncture
Arterial puncture is performed using simultaneously ultrasound in order to guide the passage of the syringe from the patient's skin to the artery

Active Comparator: Conventional arterial puncture technique
Patients randomised to the active comparator arm has arterial puncture performed using the conventional technique
Procedure: Conventional arterial puncture technique
Arterial puncture is performed using the conventional technique




Primary Outcome Measures :
  1. The proportion of patients who only needs one puncture attempt in order to successfully extract enough blood to make an arterial blood gas analysis [ Time Frame: up to 1 hour after arterial puncture ]

Secondary Outcome Measures :
  1. Time used for arterial puncture [ Time Frame: up to 1 hour after arterial puncture ]
  2. Patient corporation [ Time Frame: up to 1 hour after arterial puncture ]
    Patient corporation is subjectively estimated by the physician performing the arterial puncture. The degree of patient corporation are assessed on a scale from 1 - 5, where 1 is very poor patient corporation and 5 is perfect patient corporation.

  3. Pain Scores on the Visual Analog Scale [ Time Frame: Up to 1 hour after arterial puncture ]
  4. Number of attempts before successfully acquiring arterial puncture [ Time Frame: up to 1 hour after arterial puncture ]
