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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Ultrasound guided arterial puncture | Experimental | 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 |
|
| Conventional arterial puncture technique | Active Comparator | Patients randomised to the active comparator arm has arterial puncture performed using the conventional technique |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Ultrasound guided arterial puncture | Procedure | Arterial puncture is performed using simultaneously ultrasound in order to guide the passage of the syringe from the patient's skin to the artery |
| Measure | Description | Time Frame |
|---|---|---|
| The proportion of patients who only needs one puncture attempt in order to successfully extract enough blood to make an arterial blood gas analysis | up to 1 hour after arterial puncture |
| Measure | Description | Time Frame |
|---|---|---|
| Time used for arterial puncture | up to 1 hour after arterial puncture | |
| Patient corporation | 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. |
