Test results were compared to patients' previous three-week screening and baseline data (their current therapies) as the placebo control for each variable including all their lung functions, FEV-1, FVC, PEF, FEV-1/FVC ratios, SaO2
, nitric oxide, coughing rates and nasal inflammation.
Table 2 shows the values of HR, MAP, Ppeak and plateau inspiratory pressure (Pplateau), end-tidal CO2 and SaO2
recorded at three time intervals.
A diagnosis of respiratory failure was made after the determination of arterial oxygen pressure (PaO2) level <60 mmHg or arterial oxygen saturation (SaO2
) <90% when breathing room air, with or without elevation of arterial PCO2.
The vital signs, CVP, SaO2
, and urine of the patients were closely monitored [18, 19].
As independent variables, we included clinically relevant variables: age, gender, BMI, ESS, smoking history, AHI, oxygen desaturation index (ODI), AI, mean and minimum Sa[O.sub.2], and sleep time spent with SaO2
less than 90% (TST90).
He had a fever of 37.6[degrees]C and a room air SaO2
 La terapia con oxigeno se recomienda en pacientes con hipoxemia (SaO2
<90%) La ventilacion no invasiva se puede utilizar en los casos mas graves, como aquellos que se presentan con edema pulmonar cardiogenico.
His pulse was 122/min, blood pressure was 106/70 mmHg, and SaO2
came down to 72%.
Decreases in PaO2 rarely exceed 10 mmHg, and the PaO2 values tend to be on the flat portion of the oxyhemoglobin curve, so that drops in arterial oxygen saturation (SaO2
) are minimized.
The patient was febrile (38.4[degrees]), blood pressure was 142/88 mmHg, heart rate was 103/minute, and SaO2
