Is this patient really “(un)stable”? How to describe cardiovascular ...
2019年8月6日 · A stable condition can be defined as a situation that does not change substantially over time. But surely all critically ill patients are per se un stable as, by the very nature of being critically ill, their physiological variables—including cardiovascular dynamics—change frequently over time [ 1 ].
word “stable” often has positive connotations when used to refer to patient condition. When the resident described his patient as “being stable,” everyone agreed, knowing that this meant there had been no acute change in the patient’s condition or treatment. In fact, the patient still had profound circulatory shock.

2015年3月16日 · The control animals showed stable condition over the 8-hour anesthesia. MCAV significantly decreased during the development of sepsis (from 23.6 ± 6.6 cm/s to 16.0 ± 3.9 cm/s, P < 0.01) and pulsatility indices increased (from 0.68 ± 0.22 to 1.37 ± 0.58, P < 0.01), indicating vasoconstriction of the resistance vessels.
Pulse pressure and end-tidal carbon dioxide for monitoring low …
2020年9月22日 · Concomitant measurements of NCO, PP, and EtCO 2 were realized in stable condition (no change in VA-ECLS and ventilator settings, patients’ treatment including hemodynamic supports and level of sedation). These study points were aimed first at ensuring that the VA-ECLS setting was optimal and also for catching Th-NCO events.

2018年8月3日 · Prior to testing, patients were required to be in stable condition for at least 30 min, ventilated with fraction of inspired oxygen (FiO 2) of less than 60%, and positive end-expiratory pressure (PEEP) of less than 10 cm H 2 O without any discernable air leaks. Only stable measurements for at least 20 min were considered acceptable.

2016年11月10日 · Prior to testing, patients were required to be in a stable condition for at least 30 minutes, ventilated with inspired oxygen fraction (FiO 2) <60 % and positive end-expiratory pressure (PEEP) <10 cm H 2 O, without any discernable air leak. Only stable measurements for at least 20 minutes were considered acceptable.

2020年9月28日 · Prior to testing, patients were confirmed to be in stable condition with only steady-state measures for ≥ 20 min considered valid. mREE was compared to pREE, which was calculated at same timepoints via commonly utilized Harris-Benedict equation (HBE).
Early prediction of hemodynamic interventions in the intensive …
2021年11月14日 · Background Timely recognition of hemodynamic instability in critically ill patients enables increased vigilance and early treatment opportunities. We develop the Hemodynamic Stability Index (HSI), which highlights situational awareness of possible hemodynamic instability occurring at the bedside and to prompt assessment for potential …
A prospective trial of elective extubation in brain injured patients ...
2008年11月10日 · The need for initial intubation, however, has been extrapolated to argue that continued intubation is needed in the comatose patient despite a stable neurological condition. In a prospective randomised study, Namen and colleagues reported an incremental increase in successful extubations in neurosurgical patients with an increasing GCS.
Daily enteral feeding practice on the ICU: attainment of goals and ...
2005年3月22日 · The TISS scores were calculated for each patient and subdivided into four categories, classifying the patient's need for ICU care: in category 1 the score was less than 10 points (no need for ICU care); 2, a score of 10 or more to less than 20 points (physiologically stable condition with prophylactic overnight observation); 3 a score of more ...
