(a.) Of or pertaining to tides; caused by tides; having tides; periodically rising and falling, or following and ebbing; as, tidal waters.
Example Sentences:
(1) HFV was delivered at frequencies (f) of 3, 6, and 9 Hz with a ventilator that generated known tidal volumes (VT) independent of respiratory system impedance.

(4) As an inspiratory monitor in the curarized patient, the sensor responds quantitatively to persisting spontaneous tidal volumes of 1 ml.
(5) The tidal volume increase under CO2 inhalation was suppressed by the inflation reflex but other afferent vagal nerves seemed to be closely associated with the increased respiratory rate.
(6) Tidal volume increased by 32 percent (P less than 0.03), minute ventilation by 38 percent (P less than 0.02), dynamic compliance by 29 percent (P less than 0.004), and inspiratory flow rates by 54 percent (P less than 0.01).
(7) The relationship between mean pulmonary artery pressure (PAP) and alveolar pressures, at varying tidal volumes and opposing variable pressure to expiratory flow, was studied in 14 healthy dogs at the end of inspiration and at the end of expiration.
(8) A reduction of tidal volume to zero or an increase by 30% led to a corresponding change of mean carotid artery pH level.
(9) We have studied the EEG analysed with the cerebral function analysing monitor (CFAM) during trimetaphan (TMP)-induced hypotension to a mean arterial pressure (MAP) of 40 mm Hg in 20 normocapnic patients anaesthetized with either 1% end-tidal isoflurane or 0.5% halothane.
(10) Bohr's equation (BE); 2. ideal alveolar air equation for O2 (IDO2); 3. end-tidal (ET); 4. by the Rahn's definition of 'mean alveolar gas', i.e., alveolar pressures are defined when instantaneous respiratory exchange ratio (IRQ) equals mean respiratory exchange ratio (MRQ).
(11) The results confirmed that the fall of end tidal carbon dioxide tension (P(ET)CO2) during hyperventilation and rise during recovery was exponential.
(12) After insertion of venous and arterial (radial and pulmonary) catheters, baseline measurements of tidal volume (VT), respiratory rate (RR), ventilatory response to CO2, and arterial and mixed venous blood gases were made.
(13) To test the hypothesis that during unsupported arm exercise (UAE) some of the inspiratory muscles of the rib cage partake in upper torso and arm positioning and thereby decrease their contribution to ventilation, we studied 11 subjects to measure pleural (Ppl) and gastric (Pga) pressures, heart rate, respiratory frequency, O2 uptake (VO2), and tidal volume (VT) during symptom-limited UAE.
(14) This effect increased as lung volume decreased, so that the greatest difference between DLcoSB-3EQ after a deep breath and that after tidal breathing occurred at the lowest lung volume.
