It is a mode of ventilation controlled by tidal volume and respiratory frequency
as constant parameters, with variable inspiratory pressures.
The respiratory excursions were recorded on a chart recorder through a bridge amplifier, and respiratory frequency
(RF) was computed from these recordings.
It describes a powerful approach to estimate the respiratory frequency
from exercise ECG's and requires no additional equipment.
1] when analyzing the heart rate, relative oxygen uptake, ventilation, respiratory frequency
and perceptual responses (see Figures 2, 3, 4, 5 and 6).
To monitor the effects of dyspnea induction, inspiratory pressure, inspiratory time, and respiratory frequency
were measured continuously at the mouthpiece using computer software developed by the engineering service of HCPA.
The device can track the following vital parameters simultaneously: respiratory frequency
curve, PANI (Blood Pressure Non-Invasive), Sp02, heart rate, ECG 12 leads with print layout, core temperature and continuous transmission of data and curves.
h] denote respiratory frequency
and heartbeat frequency, respectively.
On the determination of ventilatory threshold and respiratory compensation point via respiratory frequency
c) Adequate pulmonary mechanics: respiratory frequency
below 35 rpm, tidal volume from 4 to 6 ml/ kg; d) hemodynamic stability (dopamine <5 [micro]g/kg/ min), d) temperature <38[degrees]C, Hb >10 g/dl; e) normal serum electrolytes or correction of these prior to weaning; f) Glasgow [greater than or equal to] 8.
Some modifications in cardiac, respiratory frequency
and medial arterial pressure (direct) were found, which were evaluated at 8 different times starting 5 minutes before the anestesic premedication.
The physiological responses of the animals were evaluated through the following measurements: respiratory frequency
(RF), cardiac frequency (CF), and rectal temperature (RT).
During the collection process, continuous measurements were made of the temperature and relative humidity within the chamber as well as the respiratory frequency
of the bird.
