c.Physical Function ICU Test (PFIT)

The physical strength of patients in the ICU is usually measured by looking at the patient's ability to perform or meet the needs of daily activities. The physical function of a critical patient can be measured to determine the degree of physical function impairment in the patient. Examination or measurement of physical function is expected to be able to present the real condition of the critical patient's condition in the ICU or after the patient is discharged from the ICU. physical in the ICU are responsibility, reliability and validity can use Physical Function ICU Test (PFIT). Physical Function ICU Test (PFIT) is a physical function measurement tool that can be used by critical nurses in the ICU to identify the condition of critically ill patients in the ICU. The Physical Function ICU Test is proven to be safe with high clinical utility, responsiveness to all changes, and PFIT is recommended in testing the physical function of patients in the ICU [38–40]. PFIT shows good reliability and responsiveness to changes and the respondents who take measurements safe and flexible [39]. The PFIT test was carried out on 20 respondents and all respondents measured the results obtained P < 0.05. The Physical Function ICU Test can show an increase in the progress of muscle function and muscle strength in Critically ill patients [39]. The Physical Function ICU Test can be performed on patients with a tracheostomy attached, a ventilator, the patient can follow orders, can sit, and not. Performed in patients with a fraction of inspired oxygen (Fio2) > 0.6 (> 60%); positive end-expiratory pressure (PEEP) > 8 cmH2O; patients with spinal cord injuries, stroke, and unstable fractures [39]. There are 4 Physical Function ICU Test (PFIT) domains measured, namely:
