Winck ed altri hanno confrontato l'uso del dispositivo in pazienti con patologie neuromuscolari e pazienti con BPCO severa; in questi ultimi, la dispnea e i valori di SaO2 miglioravano significativamente dopo l'in-essuflazione, ma non si otteneva un aumento del picco di Flusso Espiratorio.
Volume espettorato in giorni diversi) FEV1 SaO2 32 1) 20 min/die per 20 gg PEF 2) 20 min/die per 20 gg SaO2 PaCO2 Altre var.
Wynee and colleagues  proposed to define a desaturation dip by a fall in SaO2 by more than 4% from baseline during quiet breathing just before the episode of hypoxemia.
Though there was a good correlation between mean sleep and exercise SaO2, and minimum sleep and exercise SaO2, awake PaO2 appeared to be a better predictor for NOD than exercise desaturation .
Impact of oxyhemoglobin dissociation curve Hypoxemic patients at baseline (as measured by PaO2) are more likely to drop their SaO2 with hypoventilation during sleep, compared to normoxic patients at baseline due to the effect of the oxyhemoglobin dissociation curve 23.
During a week-long trial, I compared the OxiMax system's SpO2 readings to each patient's SaO2
values through a series of blood gas draws," continued Whitford.
From our research, we've determined that the MAX-FAST Forehead Sensor monitors SaO2 as accurately as digit-based oximetry in pediatric patients and is well-tolerated in this patient population," said Dr.
The absolute difference between the MAX-FAST Forehead Sensor or digit sensor and CO-oximetry SaO2 values was calculated and compared using a paired t-test.
Carrying this example further, if the SaO2 via arterial blood gas analysis was found to be 97.
Based on the oxygen saturation, hypoxemia is defined as an SaO2 of 90% or less.
When SaO2 falls below 90%, the steep portion of the oxyhemoglobin dissociation curve is encountered.
The system will be manufactured by Optical Sensors and will measure pH, pCO2, and pO2, as well as calculate HCO3, BE and SAO2
