Limitations in estimating critical closing pressure by noninvasive blood pressure measurements.
Limitations in Estimating Critical Closing Pressure by Noninvasive Blood Pressure Measurements To the Editor: We read with interest the article by Aaslid et al, describing the dynamic pressure-flow velocities relationships in the human cerebral circulation.1 The authors help to validate estimates of critical closing pressure (CCP) based on regular heartbeat data against long diastole determinat...
متن کاملNoninvasive blood pressure monitoring.
For more 20 years, noninvasive blood pressure (NIBP) monitors have been widely used in operating rooms and critical care units to closely monitor blood pressure in patients of all ages. Despite the widespread use of automated blood pressure monitors, clinicians continue to deliberate over the accuracy and reliability of automated NIBP devices compared to other methods of blood pressure determin...
متن کاملContinuous vs intermittent blood pressure measurements in estimating 24-hour average blood pressure.
In the past few years noninvasive automatic blood pressure (BP) recorders have been increasingly used to estimate patients' 24-hour BP more accurately than by one or few isolated measurements. However, these recorders only allow BP to be intermittently measured at intervals between 5 to 30 minutes, which means that the number of values collected over 24 hours (10 to 100) remains a tiny fraction...
متن کاملCritical closing pressure in cerebrovascular circulation.
OBJECTIVE Cerebral critical closing pressure (CCP) has been defined as an arterial pressure threshold below which arterial vessels collapse. Hypothetically this is equal to intracranial pressure (ICP) plus the contribution from the active tone of cerebral arterial smooth muscle. The correlation of CCP with ICP, cerebral autoregulation, and other clinical and haemodynamic modalities in patients ...
متن کاملLimitations of low pressure noninvasive ventilation
Sir, In recent years, we have seen an increasing use of noninvasive ventilation (NIV) in the context of acute respiratory insufficiency (acute respiratory failure). However, adherence to treatment is not perfect; partly because of patient’s complaints relating to high‐pressure levels. This led to envisaging if the use of lower ventilatory pressures could lead to the same clinical results of the...
