A sequence of fixed-size blocks defines a page (e.g., in a server system, storage subsystem, DASD, etc.). Each fixed-size block includes a data block and a footer. A high performance block storage metadata unit associated with the page is created from a confluence of the footers. The confluence of footers has space available for application metadata. In an embodiment, the metadata space is utilized to record a “write activity level” metric, and a timestamp. The metric indicates the write frequency or “hotness” of the page, and its value changes over time as the activity level changes. Storage subsystem performance may be enhanced by mapping frequently accessed pages to higher performance physical disks and mapping infrequently accessed pages to lower power physical disks. This approach is advantageous in that the metric is recorded on a non-volatile basis and may be readily communicated between system components (e.g., between a host computer and a storage subsystem).

The present invention is a system for monitoring a patient's breath chemistry comprising a plurality of components, including a self-condensing pH sensor distally mounted on a catheter, a transmitter with hydration sensing circuitry for the pH sensor, and processing receiver/data recorder. A specially designed self-condensing pH sensor is located on the distal end of a tubular catheter which is designed to be inserted into the patient's airway.

Centimeter markings imprinted on the catheter body and an optional light source located near the distal tip of the catheter is used to aid in proper positioning. A transmitter with an antenna is engaged to the proximal end of the catheter and transfers the observed pH data by employing one of many wireless methods, such as radio-frequency (RF) energy. Alternately, the transfer of observed pH data is accomplished by direct wire methods. A processing receiver/data recorder receives the data and provides a means for storing and retrieving the data for study by a physician. The transmitter also includes a means to evaluate the signal strength of the sensor, which comprises of periodically sending a low voltage signal to the pH sensor and reviewing the resulting wave forms. The signal strength system can detect if the pH sensor is non-hydrated, partially hydrated, or fully hydrated. The pH data is transferred or updated at specific intervals, which can be varied according to the patient's needs, to the processing receiver/data recorder that can include an alarming means for predetermined pH values.
