packed cell volume

First day packed cell volume also emerged as a predictor of transfusion requirements.

Packed cell volume and haemoglobin were also measured after each bleeding episode.

For those not requiring red cell transfusion there was no difference in packed cell volume between the groups at 1 month.

Moreover, haemoconcentration is noted with an increase in the packed cell volume; total proteins are initially increased, but changes into a lower than normal value.

Severe blood loss, white mucous membranes, and anemia or low packed cell volumes are common complications of the infection.

The significant difference in mean packed cell volume between our groups suggests that 'regulated' cord clamping enhanced placental transfusion.

Packed cell volume was measured in the first arterial or venous blood sample obtained, usually when establishing arterial access.

Associations have been shown between low packed cell volume or red cell volume, or both, and the respiratory distress syndrome.

As the authors have pointed out previously, packed cell volume is a poor indicator of red cell mass and a better measure would have been useful.

Packed Cell Volume (PCV) is a measure of hydration status, with a value 45% being considered significant.

Hematocrit (HCT, packed cell volume, PCV).

Our inability to standardise the timing of the initial packed cell volume is unfortunate as large changes in plasma volume occur in the first few hours of life.

Hematocrit or packed cell volume (PCV) - This is the fraction of whole blood volume that consists of red blood cells.

The effect of treatment group on final outcome measures appears to be mediated largely through its effect on arterial-alveolar oxygen tension ratio and to some extent packed cell volume.

All patients in the study received the following treatment: ranitidine 50 mg intraveneously three times per day, volume replacement with intravenous fluids, and blood to maintain packed cell volume above 28%.

Compared to the untreated mice with the disease, which they used as a control, "the treated animals had marked increases in RBC counts, healthy hemoglobin, and packed cell volume levels".

Four blood values (hemoglobin, packed cell volume, serum alkaline phosphatase and serum albumin) are measured after the trial, and the average values of the test subjects must meet minimum levels.

Differences in final outcome measures such as duration of supplemental oxygen dependence and red cell transfusion requirements were mediated primarily through arterial-alveolar oxygen tension ratio and also packed cell volume.

The packed cell volume (PCV) can be determined by centrifuging heparinized blood in a capillary tube (also known as a microhematocrit tube) at 10,000 RPM for five minutes.

The haemoglobin and packed cell volume were checked at least once daily, and a blood transfusion was given if the haemoglobin dropped to less than 9 g/dl or if the vital signs deteriorated.

Limited haemorrhage - the presence of unchanged packed cell volume, haemodynamic stability, lack of haematemesis, no evidence of blood in the gastric aspirate, and normal stools or only traces of melaena.

There were statistically significant differences between the two groups in mean initial packed cell volume (regulated group 0.564, random group 0.509) and median red cell transfusion requirements (regulated group zero, random group 23 ml/kg).

However, the significant difference in packed cell volume between the groups remained when only those samples obtained within the first two hours were compared and also when only those obtained from the third hour onwards were compared.

The equine cardiovascular system is hugely compliant with a heart rate range from 20 - 240 beats per minute and a splenic red cell reserve able to double packed cell volume and oxygen delivery during maximal exercise.

Initial packed cell volume, peak serum bilirubin concentrations, red cell transfusion requirements, and respiratory impairment (assessed by ventilatory requirements, arterial-alveolar oxygen tension ratio over the first day in ventilated infants, and duration of dependence on supplemental oxygen).
