Summary
Brief summary
The primary purpose ot the study is compare two of the commonly used needles in arterial blood gas taking and to determine the level of pain/success rate & complications. Whilst the smaller needle may be theoritically less painful, there is uncertainty whether it is more difficult to perform leading to lower success rates & complications.
