Antibiotic Resistance in Nosocomial Respiratory Infections

Clinics in Laboratory Medicine, 2014
Nosocomial respiratory infections are the most common acquired infections in patients with severe underlying conditions and are responsible for high morbidity and mortality in this patient population. Multidrug-resistant (MDR) pathogens are associated with hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP).

Estimating central and peripheral respiratory resistance

Journal of Applied Physiology, 1978
An analytic approach for fractionating total respiratory resistance into central (Rc) and peripheral (Rp) components is presented. In the analysis, linear regression equations relating the logarithm of the measured total resistance to the logarithm of frequency are derived for data spanning the frequency range 1–16 Hz. The computed slope and intercept

Fractionating respiratory resistance in young children

Journal of Applied Physiology, 1979
Total respiratory resistance (Rrs) and the fraction of this resistance located peripherally, (Fp) were measured in a group of children (3--5 yr old). The technique used forced random noise to characterize the frequency dependence of effective resistance and an algorithm to compute Rrs and Fp from these data.

Partitioning of Respiratory System Resistance in Children with Respiratory Insufficiency

American Journal of Respiratory and Critical Care Medicine, 1999
Using end-inspiratory airway occlusion, respiratory system resistance (Rrs) can be partitioned into a flow-resistive component (Rint), and an additional component (DeltaR), reflecting viscoelasticity and time constant inequalities. We studied flow and volume dependence of Rrs and its subdivisions (Rint and DeltaR) in 13 children, seven mechanically ...

Antimicrobial resistance in respiratory tract pathogens

Expert Review of Anti-infective Therapy, 2004
Antimicrobial resistance has been a problem ever since the introduction of antimicrobial agents 60 years ago. Today, this problem is increasing so rapidly that the end of the antimicrobial era is being predicted. The increasing problems caused by antimicrobial resistance can be illustrated by those seen in bacterial pathogens that cause community ...

Validation of Respiratory Resistance Measurements

ASME 2011 Summer Bioengineering Conference, Parts A and B, 2011
The airflow perturbation device (APD) has been developed as a portable, easy to use, and rapid-response instrument for noninvasively measuring respiratory resistance in humans. However, the APD has limited data validating it against established techniques; moreover, a method does not exist to standardize resistance measurement outputs between APD units.

An analysis of respiratory drive components during flow-resistive respiratory loading

Annals of Biomedical Engineering, 1983
Inspiratory flow-resistive loading normally causes an additional respiratory drive that limits the resistance-induced decrease in minute ventilation (load compensation). Occlusion pressures (P100) were measured during CO2 rebreathing with and without added inspiratory loads in normal persons and persons with obstructive sleep apnea (OSA). At each point

Respiratory Infections Due to Drug-Resistant Bacteria

Infectious Disease Clinics of North America, 2010
Pneumonia is the most common infection that is the leading cause of death. The increasing antimicrobial resistance in major respiratory pathogens such as Streptococcus pneumoniae, Staphylococcus aureus and gram-negative bacteria has severely restricted the treatment options.
