hypoxemia

A group of specific clinical signs seem useful in predicting hypoxaemia.

Table III shows the association of individual signs or symptoms with hypoxaemia.

A total of 151 (59%) children had hypoxaemia.

Alcohol may also contribute to nocturnal hypoxaemia by causing narrowing of the upper airways.

In addition, we have shown that the physiological measurement of hypoxaemia is significantly related to prognosis and to clinical signs.

Twelve of the 18 patients with clinically undetected baseline hypoxaemia were born preterm.

These infections may be accompanied by clinically undetected baseline and episodic hypoxaemia.

Several studies in adults in developed countries, however, have shown that hypoxaemia on admission is a predictor of death in hospital.

In four of these hypoxaemia induced by epileptic seizure was recorded during subsequent events in hospital.

Some of our patients with suffocation or hypoxaemia induced by epilepsy might have died without a definite diagnosis and appropriate management.

To determine the prevalence, clinical correlates, and outcome of hypoxaemia in acutely ill children with respiratory symptoms.

Our patients were manifesting potentially dangerous hypoxaemia, and we did not consider it ethically appropriate to withhold this form of treatment.

Also, hypoxaemia and hypercapnia should be avoided.

Outcome definitions - Hypoxaemia was defined as arterial oxygen saturation less than or equal to 90%.

Obesity can increase nocturnal hypoxaemia, and we found a positive relation between body mass index and the presence of oedema.

Retractions were sensitive but not specific, and grunting was not significantly associated with hypoxaemia in these newborn infants.

We are not aware of reports from developing countries of the outcome of hypoxaemia in children with acute lower respiratory tract infection.

Each clinical finding was assessed by χ 2 test for association with the outcomes of hypoxaemia and radiographic pneumonia.

Conversely, the absence of hypoxaemia predicts a low risk of death, even in the presence of radiographic pneumonia.

The decrease in CO could also potentiate this effect as ventilation would be suppressed, leading to potential hypoxaemia.

The use of multiple logistic regression allowed the selection of the most useful clinical signs which are predictive of hypoxaemia.

We were, however, able to identify a group of clinical findings which seem useful in predicting the presence of hypoxaemia in this clinical setting.

Thus epileptic seizures often began with a sustained tachycardia in spite of apnoeic pauses and severe hypoxaemia.

The presence of hypoxaemia predicted radiographic pneumonia with a sensitivity of 71% and specificity of 55%.

Twenty nine of these 40 patients (15 with baseline hypoxaemia and 14 with recurrent hypoxaemic events) received continuous additional inspired oxygen.

Oxygen on long term may be necessary in patients with significant hypoxemia.

However, although the hypoxemia is overcome there seems to be no effect on overall survival.

It is used in diagnosing the source of hypoxemia.

Hypoxemia (a condition in which there is not enough oxygen in the blood).

During exercise, almost half of the hypoxemia is due to diffusion limitations (again, on average).

A variety of conditions that physically limit airflow can lead to hypoxemia.

This combination can lead to inadequate oxygen supply, resulting in potential hypoxemia.

Giving extra oxygen if shortness of breath is caused by hypoxemia.

Many patients have hypoxemia at rest, and all patients desaturate with exercise.

Decrease in overall thyroid function is correlated with fetal hypoxemia.

Arterial blood gases may reveal hypoxemia when tested in a lab.

Severe lung injury and hypoxemia result in high mortality.

The A-a gradient is useful in determining the source of hypoxemia.

Patients with hypoxemia may be given supplemental oxygen.

Disagreements exist concerning the scope of the term hypoxemia.

Many of the causes for hypoxemia fall into the general category of problems that concern the lung and heart.

For example, shock may lead to hypoxemia (a lack of oxygen in arterial blood) or cardiac arrest.

With worsening fetal hypoxemia, there is decline in fetal activity.

Impaired diffusion across the blood-gas barrier in the lung can cause hypoxemia.

However, further disease or a stress such as any increase in oxygen demand may finally unmask the existing hypoxemia.

Pulse oximetry can provide an early warning of hypoxemia.

Hypoxemia causes cell death and organ dysfunction .

An elevated serum bicarbonate level, or chronic hypoxemia.

Findings in these patients include hypotension, hypoxemia, seizures, and impairment of cognitive ability.

In addition, the fever, tachycardia and hypoxemia caused by influenza may be harmful to the developing fetus.
