1. INTRODUCTION AND INTENDED USE
INTRODUCTION
The CARDELL Veterinary Monitors, Models 9401 and 9402, are vital signs monitors measuring
blood pressure and oxygen saturation. The monitors are restricted for use, one patient at a
time. Non-invasive blood pressure is measured using the oscillometric technique determining
systolic, diastolic, mean arterial pressure and pulse rate. The pulse oximeter function
continuously monitors and displays values for functional arterial hemoglobin saturation and a
pulse rate.
BRIEF DEVICE DESCRIPTION
The CARDELL Monitor is compact, lightweight and portable, allowing it to be easily carried and
used in a variety of clinical settings. The monitor is powered by AC Line Power or by a Nickel
Metal Hydride (NiMH) rechargeable battery pack. The internal battery pack charges when the
monitor is plugged into the AC wall outlet. The CARDELL Monitor can be set to operate in one
(1) of nine (9) different languages: English, German, French, Italian, Spanish, Dutch, Swedish,
Portuguese or Norwegian. The message window can display various system alarm messages.
These messages direct the user to check conditions such as the battery state, air leaks and
measurement problems. The message window also displays the operational mode of the
monitor (automatic or manual).
The non-invasive blood pressure (NIBP) parameter automatically inflates an occluding cuff and,
using the oscillometric measurement technique, determines systolic, diastolic and mean arterial
pressure and pulse rate. Measurement results along with operator prompts and error messages
are displayed on the front panel. The frequency of NIBP determination can be selected by the
operator in varied times between one and ninety minutes. The auto and manual operating
modes cover a variety of clinical uses.
The pulse oximeter parameter (%SpO
2
) determines arterial oxyhemoglobin saturation by
measuring the absorption of red and infrared light passing through the tissue. Changes in
absorption caused by pulsations of blood in the vascular bed are used to determine arterial
saturation and pulse rate. The oximeter requires no routine calibration or maintenance.
Oxygen saturation and heart rate are displayed on light emitting diode (LED) digital displays.
On each detected pulse, the perfusion LED does indicate patient perfusion signals. This bar
graph gives the user a pulse-by-pulse visual indication of waveform signal quality. An audio
“beep” can be enabled that is generated each time the SpO
2
module detects a pulse.
NOTE:
The bar graph is not proportional to the pulse volume.
