An exciting new upgrade to the proven Doppler technology, the monitor combines the proven\u00a0ODM\u00a0Doppler measurement of blood flow with Pulse Pressure Waveform Analysis (PPWA). This provides users with a proven, highly sensitive \u201cFlow Monitoring Mode\u201d to guide intervention and the simplest calibration of a \u201cPressure Monitoring Mode\u201d for extended continuous monitoring yet devised. The ODM+\u00a0has a Pulse Pressure Waveform (PPWA) mode which is quickly and easily calibrated at any time and as often as required, from the Doppler signal and provides continuous monitoring.<\/p>\n<figure id=\"attachment_397\" aria-describedby=\"caption-attachment-397\" style=\"width: 300px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-397 size-medium\" src=\"https:\/\/www.deltex-academy.com\/decision_tree\/wp-content\/uploads\/2017\/01\/ODM4-300x284.png\" width=\"300\" height=\"284\" srcset=\"https:\/\/www.deltex-academy.com\/decision_tree\/wp-content\/uploads\/2017\/01\/ODM4-300x284.png 300w, https:\/\/www.deltex-academy.com\/decision_tree\/wp-content\/uploads\/2017\/01\/ODM4.png 766w\" sizes=\"auto, (max-width: 300px) 85vw, 300px\" \/><figcaption id=\"caption-attachment-397\" class=\"wp-caption-text\"><span style=\"color: #000000; font-family: arial, helvetica, sans-serif;\"> <b>Flow Monitoring Mode using the oesphageal Doppler probe.<\/b><\/span><\/figcaption><\/figure>\n<figure id=\"attachment_398\" aria-describedby=\"caption-attachment-398\" style=\"width: 300px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-398 size-medium\" src=\"https:\/\/www.deltex-academy.com\/decision_tree\/wp-content\/uploads\/2017\/01\/ODM3-300x287.png\" width=\"300\" height=\"287\" srcset=\"https:\/\/www.deltex-academy.com\/decision_tree\/wp-content\/uploads\/2017\/01\/ODM3-300x287.png 300w, https:\/\/www.deltex-academy.com\/decision_tree\/wp-content\/uploads\/2017\/01\/ODM3.png 761w\" sizes=\"auto, (max-width: 300px) 85vw, 300px\" \/><figcaption id=\"caption-attachment-398\" class=\"wp-caption-text\"><span style=\"color: #000000; font-family: arial, helvetica, sans-serif;\"><b>Pressure Monitoring Mode using the arterial wave calibrated from the oesophageal Doppler cardiac output.<\/b><\/span><\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>The PPWA algorithm can be recalibrated at any time, when there is known or suspected arterial compliance changes, from the Doppler waveform.
