Hand grip strength as a predictor for success in weaning from ventilation

Timely extubation is important integral part of the treatment of intensive care patients.


To evaluate hand grip strength using a Jamar Hydraulic Hand Dynamometer as a predictor of success or failure in weaning from ventilation.


This prospective study included 104 patients (62 males, 42 females) who were ventilated in the general intensive care unit (ICU), and who were alert and cooperating. They undertook a hand grip strength test using the Jamar dynamometer, within hours of extubation. Patients needing resuscitation within 72 hours were defined as failure.


Success rate in weaning from ventilation was 85.6%, and 89 patients successfully weaned from ventilation. Those who were successfully weaned had stronger hand grip than those who failed. Males had a mean kg-strength 31.3 ± 11.5 vs. 23.6 ± 10.3 (P = 0.033), and in females mean kg-strength 23.14 ± 16.39 vs. 11.67 ± 10.33 (P = 0.031). A threshold value (22.5 kg-strength) was found to predict success for weaning from ventilation in the male group, with a sensitivity of 70.0% and a specificity of 62.5%. In the female group, the duration of the ventilation alone was statistically significant (P = 0.049).


There was a connection between hand strength and success in weaning from ventilation. A threshold value can help the medical staff to decide on extubation. Hand grip strength can predict successful weaning from ventilation and does not require high skills, time, a large staff, or high financial cost, and it does not endanger the patient.
