294(24):3124-30.. Ram FS, Picot J A normal I:E ratio at rest is about 1:2, and so the default duration of the expiratory phase in mechanical ventilation is approximately twice the duration of the inspiratory phase. There is a theoretical benefit in increasing the I:E ratio to improve oxygenation. expirium/inspirium time ratio are also derived. In a group of 10 healthy subjects, a phase lag difference of 11.4+/-8.5% was observed between supine and standing postures, possibly ascribed to breathing mechanics.

2. Hypovolemia and decrease in P[ v with bar above]O 2. Pa O 2 is lower when the mixed venous oxygen tension (P[v with bar above]O 2) is decreased, as can occur with decreased cardiac output, increased oxygen consumption, or severe anemia with increased oxygen extraction.The effect of P[v with bar above]O 2 can be quite significant, especially when there are areas of low [V with dot above]A/[Q
Physical examination of the patients with PSP is generally normal except moderate tachycardia. A decrease in respiratory sounds is observed during the auscultation of the concerning side. If a heart rate of more than 140 pulse/min, hypotension, cyanosis, or electromechanical dissociation exists, pneumothorax should be suspected.

These results suggested that hemodynamic and ventilation parameters may likely affect intraocular pressure by decreasing drainage of aqueous humor from episcleral veins.
One book said it's normally 1:1 and another said it's about 1:2 or 1:3.

Inspektion. - Andningsfrekvens och andningsarbete: Ansträngd, snabb andning indikerar ökade krav på andning (ökat andningsdriv) eller ökat motstånd mot andning (obstruktion). Vid obstruktion ses paradoxal andning, dvs att arbete krävs för exspiration (acessoriska andningsmuskler).

volume. Because gas flow curve during expirium is degressive (exponential), the time required to reach 63 %, 85 % or 96 % of expiratory volume, represent the time constant τ edyn1, τ edyn2, or τ edyn3. Generally for further calculation the first expiratory dynamic time constant value is used τ edyn1, indicated further as τ edyn.

Head trauma patients might exhibit a reduction in FRC and pulmonary compliance and an increase in pulmonary shunting without evidence of pulmonary disease on the chest radiograph.
