Intervention: Assessment of accessory respiratory muscles work
Description: Patrick score calculation. Score: 0. No visible tonic or phasic use of neck muscles. 1. Neck muscles taut but with no respiratory modulation (i.e., tonic activity). 2. Mild respiratory modulation in neck muscle contraction. 3. Moderate phasic activity (no supraclavicular or intercostal indrawing). 4. Vigorous phasic activity with indrawing. 5. Vigorous phasic activity with abdominal paradox.
