Mechanical Power Versus Diaphragmatic Excursion As a Predictor for Weaning in Chronic Obstructive Pulmonary Disease Patients

NCT06510517 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 84

No results posted yet for this study

Summary

The primary objective is to evaluate the mechanical power as a predictor of weaning of mechanical ventilation in COPD patients hospitalized in the respiratory intensive care unit of Assiut University Hospital.

The secondary objective is to compare between mechanical power and diaphragmatic excursion (DE) assessed by ultrasound as a predictor of weaning in these patients. Also, to investigate the association between MP and DE and mortality in these patients

Conditions

  • Mechanical Power

Interventions

OTHER

Calculation of Mechanical Power.

Total respiratory rate (RR). Positive end-expiratory pressure (PEEP) (the external or applied PEEP) recorded, not the total PEEP, or intrinsic PEEP. The plateau pressure (Pplat) was measured during an inspiratory pause on the ventilator. Peak inspiratory pressure (Ppeak) should be obtained while the patient is relaxed, not coughing or moving in bed. MP was calculated according to Gattinoni's simplified mechanical power equation as follows (3,8): MP(J/min)=0.098×VT×RR×(Ppeak-0.5×ΔP).

OTHER

Measurement Diaphragmatic Excursion after first SBT

Chest ultrasound to assess diaphragmatic excursion (DE(. M-mode was used to record the movement of the diaphragm during tidal breathing when the sampling line and diaphragm were as vertical as possible (not \< 70°). The data was measured from the first respiratory cycle at 0 min after SBT. The DE at 0 min, 5 min, and 30 min of SBT was respectively named as DE0, DE5, and DE30. The variation of right DE between each time point was named as ΔDE30-5 and ΔDE30-0. (7)
