What ICU Mobility Scale levels indicate activity capability?

IMS 0: nothing in bed; 1-2: active movement; 3: sitting on edge of bed; 4: standing; 5: transfer to chair; 6: marching in place; 7: walking with 2 people; 8: walking with 1 person; 9: walking independently with aid; 10: walking independently.

What safety criteria must be met before ICU early mobilization?

Cardiovascular: MAP ≥65 with stable vasopressor doses; respiratory: FiO2 ≤0.6, PEEP ≤2 cmH2O; neurological: RASS ≥-2; other: no ECMO, IABP, or emergency planned procedures in next 2h.

What events should terminate an ICU mobility session?

Stop if: HR >130 or 40, SpO2 1 min, MAP >110 or <65, vasopressor increase required, patient requests stop, patient falls, accidental device removal.

What outcomes does early ICU mobilization improve?

ABCDEF bundle (including early mobility): reduces ICU LOS 3-4 days, hospital LOS 5-6 days, 180-day mortality 28-day delirium duration; patients more likely to be walking independently at hospital discharge; muscle loss reduced.

What is the ICU-acquired weakness classification?

ICU-AW diagnosed by MRC sum score <48/60 (6 muscle groups, bilateral); severe ICUAW MRC <36/60; critical illness polyneuropathy (CIP) and critical illness myopathy (CIM) are the main subtypes; early mobilization reduces severity.

ICU Mobility Scale and Early Mobilization Safety Checklist

Calculates the ICU Mobility Scale (0-10) and SOMS safety checklist to guide progressive early mobility in mechanically ventilated ICU patients, including criteria for sitting, standing, and ambulation readiness.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.
