Functional residual capacity and absolute lung volume

Current Opinion in Critical Care, 2014
To discuss the role of measuring functional residual capacity (FRC) during mechanical ventilation to improve patient ventilator settings in order to prevent ventilator-induced lung injury.Nowadays, FRC can be measured without the use of tracer gases and without disconnection from the ventilator.

A fundamental problem in determining functional residual capacity or residual volume

Journal of Applied Physiology, 1986
To measure a lung volume that is not directly accessible, one often follows dilution of a single-gas tracer, present initially only in the lung or in a rebreathing bag. The final volume available to the tracer is assumed to be the sum of the two initial components.

Diaphragm thickness heterogeneity at functional residual capacity and total lung capacity

Journal of Applied Physiology, 1995
One of the determinants of muscular force is the number of myofibrils in parallel, which is approximated by thickness. To better understand the heterogeneity of diaphragm thickness, we quantified the interregional and radial patterns of thickness of nine canine diaphragms rapidly perfusion fixed in situ with glutaraldehyde at functional residual ...

Postoperative nitrous oxide analgesia and the functional residual capacity

Critical Care Medicine, 1983
Surgery of the upper abdomen is associated with the greatest demand for postoperative analgesia and also is marked by depressed pulmonary function, arterial hypoxemia, and pulmonary complications. Nitrous oxide (N2O) in concentrations of 15-25% is a potent analgesic and is relatively free of untoward side effects if administered for a maximum of 48 h ...

Automated Evaluation of Functional Residual Capacity by Oxygen Washout

Journal of Clinical Monitoring and Computing, 2002
Measurement of functional residual capacity (FRC) is of considerable interest for monitoring ventilated patients in ICUs. However, the lack of instruments that can be used in the clinical setting has so far impeded the routine application of this measurement.

Functional residual capacity and body position in the dog

Journal of Applied Physiology, 1978
Resting lung volumes in the supine position (FRCs) were determined by N2 washout method in 67 dogs under pentobarbital anesthesia and computed in ml/kg body weight (BW). In 21 other dogs, FRCs and the change in FRC from the supine to upright positions (deltaFRC) were determined; these lung volumes were expressed in ml/kg BW and in percentage of TLC40 (

Oxygen wash-in method for monitoring functional residual capacity

Critical Care Medicine, 1982
Atelectasis, pulmonary edema, fibrosis, pneumothorax, and mucous plug airway obstruction all result in reduced lung volume. The oxygen (O2) wash-in method provides a way to monitor routinely the functional residual capacity (FRC) in the ICU without disconnecting the patient from the ventilator and without additional personnel or instrumentation.

Functional residual capacity: the human windbag.

AANA journal, 2002
Like the windbag of a bagpipe, the functional residual capacity (FRC) is the lung volume that acts as a reservoir of air for physiologic use. This reserve volume is particularly important during the period of apnea that occurs during induction of general anesthesia.

Absolute intraesophageal pressure at functional residual capacity in frequency

Journal of Applied Physiology, 1981
Absolute intraesophageal pressure at functional residual capacity (FRC) has been estimated in 15 infants (age 1-30 wk) by the extrapolation of the esophageal pressure-volume relationships to zero balloon volume by use of air-filled balloons in their ranges of infinite compliance. The pressure-volume relationships of the esophageal balloons (length 3.5-

Measurement of Functional Residual Capacity during Mechanical Ventilation

2010
Functional residual capacity (FRC) is defined, in classical physiology, as the volume of gas remaining in the lungs at the end of expiration. In other words, FRC is the volume at which the elastic recoil pressure of the chest wall equals that of the lung and, at FRC, the system is in equilibrium.
